TRANSISTORIZED LAND MINE DETECTOR WITH IMPROVED SENSITIVITY DEVELOPED FOR U. S. ARMY BY TEXAS INSTRUMENTS INCORPORATED DALLAS, January 6 --(Special)--Texas Instruments Incorporated has developed a new light-weight transistorized land mine detector for the U. S. Army with greatly increased ::; eneitivity and other advantages over detectors currently in use, it was announced today by W. F. Joyce, TI Vice President in charge of the Apparatus division. Because it is transistorized, the new detector has a much longer battery life and enhanced reliability under rugged field conditions of use, it was pointed out. Use of transistors also has permitted miniaturization of the device to the point where all parts except the antenna can be carried under the operator's clothing. This is considered of special importan'-=e where the detector is to be used in Arctic regions. The detector also is fungus proof for advantageous use in the tropics. Texas Instruments worked with the Engineering Development Laboratories, Corps of Engineers, Fort Belvoir, Va., in developing the transistorized land mine.

It already has had a pilot production run leading

toward more extensive production commitments, TI announced. Developmental work took place in Tl's Apparatus division, an important s upplier of electronic and electromechanical apparatus and systems for the nation's defense and for civil governmental agencies.

Tl's Semiconductor-

Components division is the world's leading manufacturer of transistors and r e lated devices.

FOR ANNUAL BUSINESS EDITIONS

GAINS IN SALES, EARNINGS, PRODUCT DEVELOPMENT, PLANT FACILITIES MAKE 1957 A YEAR OF UNPRECEDENTED GROWTH FOR TEXAS INSTRUMENTS DALLAS, January 9- -{Special)- -Substantial gains in sales and earnings and expansion in product development and plant facilities made 1957 another year of unprecedented growth for Texas Instruments Incorporated, President Erik Jonsson said today. Gains over the preceding year were registered in all principal lines of TI activity, accompanied by planning and preparation for still further growth in 1958 and the years beyond, he said. New company records were established in the sale of transistors and related semiconductor devices, electronic and electromechanical apparatus and systems for the nation's defense, and in contract services to oil companies for geophysical exploration for petroleum. Net sales and earnings for 1957 are expected to exceed the $65,000,000 and

$1. 10 per share of common stock, respectively, forecast earlier in the year, when final compilation of the year's results is completed, Mr. Jons son said.

These

represent approximately a 45% increase in sales and better than a 50% increase in earnings per share over 1956 results, which totalled $45, 700, 000 in net sales and earnings of 72¢ per share of common stock. During 1957, TI began its first manufacturing activity outside the United States with the production in a new plant at Bedford, England of semiconductor devices for marketing in the Sterling area.

At the year's close, Tl's new 310,000

page two growth of ti sq ft plant on its new 300-acre North Central Expressway site in Dallas was nearing its final stage of completion with occupancy by the Semiconductor ­ Components division scheduled for early spring. At that time, Tl's Apparatus division will take over full occupancy of the company's 240,000 sq ft main plant at 6000 Lemmon avenue in Dallas. As the year closed, Geophysical Service Inc. and TI 's other geophysical subsidiaries had more than 70 crews engaged in exploration for oil in 18 countries of the free world, marking an all-time high in this phase of the company's activity. In the area of new product development, TI entered the basic material field during 1957 with the commercial production and sale of high purity silicon.

TI

also achieved another important milestone with the commercial production of .a new gaseous diffused-juncti on silicon transistor having many times the power output of then available units.

TI continued to supply transistors for use in the majority

of portable radios manufac br ed. and in 1957 supplied transistors for the first portable radios for automobiles, introduced in some 1958 model cars. Tl's Apparatus division developed and began the manufacture for the U.S. Air Force of a new photographic mapping radar system which, when carried aloft, produces a strip photograph of the picture appearing on the radar scope covering a broad corridor of the terrain below. Because the corridor portrayed extends out on each side of the plane's path, its developers have described the system as a "sidelooking" radar. As 1958 opened, Texas Instruments began work on a contract with the

TI also was engaged in supplyin g compon ents for five differen t guided missile s and with designin g or redesig ning for use of silicon transist ors many complet e systems for the missile program .

Additio nally, it was manufa cturing

for the nation's defense s detectio n systems used for aerial reconna issance and antisub marine warfare , aircraf t early warning and aircraf t commu nication s system s. All of this reflecte d the high level of researc h and develop ment activity which is a continui ng basic part of Tl's industr ial effort. Accomp anying the expansi on of Tl's sales, product lines and physica l facili­ ties during 1957 has been a corresp onding increas e in its employ ment rolls. Beginni ng 1957 with 4,200 employ ees, the total had been increas ed 1.omore than 5,000 by January 1, 1958, about 3,900 of them in Dallas, making TI the third largest manufa cturing employ er in the Dallas area.

Indicati ve of the high

TEXAS INSTRUMENTS PRESIDENT PREDICTS SALES APPROXIMAT ING $80 MILLION FOR 1958 IN ADDRESS BEFORE SECURITY ANALYSTS OF SAN FRANCISCO SAN FRANCISCO, January 20--{Special)- -President Erik Jonsson of Texas Instruments Incorporated, Dallas, Texas, told the Security Analysts of San Francisco today that his company's net sales probably would approximate $80 million for 1958. Earnings for 1958, he added, are expected to bear the same relationship to sales as they do for 1957. These would compare with 1957 net sales of approximately $67 million and earnings slightly over $1. 10 per share of common stock. Addressing the analysts group in a luncheon meeting at the Fairmont Hotel, Mr. Jonsson said 1957 h1d brought sales increases for all major phases of the company's activities. At year -end, he said: Exploration activity was at an all-time high for Geophysical Service Inc. and Tl's other geophysical subsidiaries, with 71 crews active in 17 countries of the free world. The crew total since has increased to 73, another new high. TI had a total government backlog of $27, 600, 000 and the Apparatus division now is working on major portions of electronics systems for five guided missiles as well as on detection systems used for aerial reconnaissanc e and antisubmarine warfare and aircraft early warning and aircraft intercom systems.

TI' s Semicondu ctor -Componen ts divis ion had more than doubled its volume of transistors and related semiconduc tor devices over 1956 s volume. 1

Mr. Jonsson revealed that the first of a number of buildings projected for Tl's new 300-acre site in Dallas--a 310,000 sq ft plant for the Semicondu ctor-Compo nents division--c urrently is being partly occupied, with full completion slated for early spring. This facility, he said, would permit new economies and increased production volume for the division. He emphasized the growing importance of research, developmen t and engineering at Texas Instrument s and the steady increase in budgeted expenditure s for these purposes. Total expenditure s for all classes of technical effort--TI' s own and that sold to others--am ounted to $2,500,000 in 1954, nearly $9,500,000 in 1957, and probably will increase to about $16,250,00 0 during 1958, he said. No acquisition s or mergers presently are pending or in prospect, he told the analysts. Mr. Jonsson expressed himself as being optimistic for 1958 and the years beyond. ''We are a part of the dynamic electronics industry, and most emphatical ly 11 he said. "We are the largest geophya part of the growing semiconduc tor business,

at six volts and 100 microfarads at 15 volts, stability within 10 percent of rating from -80°C to plus 85°C, and plus or minus 20 percent capacity tolerances at 25°C. Mechanically, the tan-TI-cap capacitor provides a

solution

to many of the major space and mounting problems for designers of miniaturized circuitry.

The case, which is cylindrical and without a

protruding lip, measures only 0. 358 by 0. 173 inch for the smallest device and 0. 700 by 0. 264 inch for the largest.

Its clean design permits vertical

or horizontal mounting on printed circuit boards within a minimum of space. The unique construction of tan-TI-cap capacitors permits maximum ratings in small packages.

tan-TI-cap capacitors are constructed of a solid

pellet of pressed and sintered tantalum powder with an integral wire lead. The dielectric is formed by a tantalum-derived coating deposited electrochemically on the pellet, resulting in a semiconductor-type junction with the solid electrolytic.

The pellet is solidly embedded within the case

to withstand high and low frequency vibrations and high impact. To facilitate printed circuit board mounting in close spaces, the leads of all tan-TI-cap capacitors can be bent sharply in any direction because the leads and welds are anchored within the case.

All leads are

guaranteed to withstand a three -pound pull in any direction for up to 30 seconds.

The solid construction of tan-TI-cap capacitors eliminates

one of the major causes of failure in other .m iniature capacitors, that of leakage.

Because tan-TI-cap capacitors contain no liquid or paste material,

they cannot leak. (more)

These advantages are achieved by completely dry construction ( no liquid or paste is used) and the chemical stability of tantalum and its oxides. Typically, the anode for this capacitor is a porous tantalum pellet. A film of dielectric material, tantalum oxide, T A,O,, is formed electrochemically on the tantalum interfaces of the pellet. The capacity of the unit is inversely proportional to the film thickness, whereas working voltage is directly related to film thickness. A semiconductor material, MnO.,, is then deposited over the tantalum diox­ ide film. The MnO., is an electronically conducting material which heals any pores in the Ta,O,,,- and together with the Ta,O,,, forms a p-n junction which is the current barrier of the dielectric. Thereafter, conducting coatings of graphite and copper, which form the cathode, are applied to the pellet in order to form a good conducting bond to the case.

capacitor characteristics. The important tan-TI-cap characteristics are: impedance, dielectric absorption, leakage, power factor, and dissipation factor. Dielectric absorption and leakage are properties of the dielectric material, whereas the capacitor's physical and chemical properties affect impedance, power factor, and dissipation factor.

definitions and relationships -

impedance. Since capacitors in the electrolytic range have resistance as well as capacitance, an impedance is introduced in the circuit. This impedance will vary with the frequency of the applied voltage. In most cases, the actual capacitor impedance at the principal operating frequency is a more direct indication of capacitor performance in a circuit than power factor, dissipation factor, or leakage.

dielectric absorption. A characteristic of the dielectric which determines the ability of the capacitor to deliver

its stored energy in a short period of time ( sometimes called dielectric hysteresis or dielectric "soak"). This characteristic is the reappearance of potential across the capacitor, after it has been shorted and the short removed. It is an important, and often critical, characteristic for RC timing networks, triggering systems, computers, and high-reliability military equipments. Increasing the ambient temperature has the effect of shifting the dielectric absorption curve to the left, but does not affect the amplitude nor the shape of the curve. On the other hand, shortening the charging time, lengthening the discharge time or decreasing the magnitude of the charging voltage will result in the reduc­ tion of the peak amplitude of the dielectric absorption curve, but will have very little effect on its charac­ teristic shape or its position with reference to the abscissa.

leakage. The amount of direct current, not charging current, that will flow steadily through a capacitor. It is an

important consideration when the capacitor is used in coupling or other applications where direct current is imposed upon the capacitor.

power factor. The power factor is numerically equal to the cosine of the capacitor's phase angle ESR

Power Factor = cos 0 when ESR = equivalent series resistance.

ESR" + X/

• ✓--=~----

This characteristic appraises the total capacitor losses, which include dielectric losses due to leakage and dielectric absorption, and ohmic losses due to contacts, leads, and high frequency skin-effects. The ohmic losses have a more pronounced effect on the capacitor's power factor, and become particularly important as frequency is increased. The better the capacitor, the lower will be the power factor.

dissipation factor. The dissipation factor is numerically equal to the cotangent of the capacitor's phase angle. DF

ESR = cotangent 0 = -X-,.

This term is encountered in capacitor testing, since many bridges give a direct reading of dissipation factor. Similar to power factor, a low value indicates a better capacitor. For phase angles greater than 80 °, there is very little difference, numerically, between dissipation factor and power factor. The relationship between power factor and dissipation factor is: Power Factor = DF

-✓ 1 +lDF"

Generally, power factor and dissipation factor are expressed as percentages.

INCREASING IMPORTANCE OF SEMICONDUC TORS IN MILITARY ELECTRONIC S EMPHASIZED BY CHIEF ENGINEER OF TEXAS INSTRUMENTS APPARATUS DIVISION NEW YORK, March 24--(Special)- -Use of semiconductor devices in airborne electronic systems is significantly extending the range and increasing the reliability and payload of missiles and military aircraftp H.J. Wissemann, Assistant Vice President and Chief Engineer of Texas Instruments Incorporated Apparatus divisionp said today. Transistorizat ion of a single system in a patrol bomber--some thing as prosaic and comparatively simple as a 14-station intercom--elim inates more than 100 pounds of dead weight while increasing reliability and reducing maintenancep Mr . Wissemann pointed out. And the opportunities for successfully transistorizing military electronic syst ems are broadening steadily, he added, as the state of the semiconductor art adv ances and devices with new and improved characteristic s are produced. Texas Instruments is introducing at the Radio Engineering Show, \now under

way at the Coliseum here, a new transistorized subcarrier oscillator and a solid-state electTonic commutator with no moving parts, both designed to increase environmental t o l erances of telemetering systems . 11

Silicon transistors, with their small size, light weight and low power drain,

c ombined with characteristic s which make them operabl e at extreme temperatures a n d ruggedness which permits them to withstand severe shock and vibration, are meeting the exacting demands of missile circuitry in an ever widening range of (more)

page 2 wissemann application, 11 Mr.

1Nis semann

said.

He cited as examples the successful transistorization of telemetering, infrared detection and mapping, and missile guidance systems. Other systems which have been or are being completely transistorized include those used in aircraft instrumentation, radar, sonar, intercommunication, magnetic airborne detection, attack navigation, and computers. Semiconductor devices have been used even in land mine detectors for the ground forces, he said, with resultant reduction in size and weight and increased sensitivity. TI has developed extremely compact telemetering transmitters in special units to 200 watts output in a 3 x 4 x 5-inch package. TI also has developed telemetering units with transistorized keyers, choppers, signal processors and other subassemblies. Transistors are replacing vacuum tubes in infrared detection and mapping systems, giving low level signal amplification with a reduction in weight, volume and power r.equirements, Mr. Wissemann pointed out.

He said that transistorizing pre-

amplifiers makes possible infrared systems offering numerous separate information channels. Previously, in attack-navigation systems, a separate analog computer was necessary for each attack or navigation function.

This system contained unreliable

and bulky mechanical parts such as gear trains, servos and synchros.

Now a single

transistorized digital computer performs multiple attack navigation functions, he said. Although detailed performance characteristics of transistorized missile-guidance systems remain classified, Mr. Wissemann said that semiconductor applications are widely made in this field. (more)

page 3 wissemann In radar, sonar and magnetic detection equipment, successful transistorizati on of major components and circuits such as IF strips, video and audio amplifiers, timing or synch circuits, certain sweep circuits, and servo amplifier circuits, is being accomplished, he said, and the feasibility of semiconductor components applications to high voltage power and modulator circuits has been proved. A phase sensitive voltmeter with a 100 microvolt resolution, developed as a part of a missile checkout system and now entering the production stage, has been successfully transistorized , Mr. Wissemann revealed,

A unique feature allows it to

reject over I 000 times as much out-of-phase voltage as it admits to the reading, he said.

In addition to the advantages of small size, weight and low power requirements, transistorized mine detectors are virtually non-microphon ic and don't alter signals when subjected to shock or vibration, he pointed out. Despite heavy emphasis on transistorizati on in the industry, each circuit must ultimately be designed using the component that is best suited for the overall system. 11

That decision depends on a combination of economics, requirements and

the current state of a rt. 11 But current strides in effective transistorizati on of military systems, with

the many new advantages each step brings to the system, are expected to accelerate considerably,

In 1957, approximately 12 per cent of the combined total units of

receiving tubes and transistors consumed by the government was transistors. 1962, Mr. Wis semann estimates, government consumption of transistors will approach 45 per cent of the total units of transistors and receiving tubes.

such as thermislors , have heen characterized by a. decreasr:: in resistance with a rising t empP.ralur<>. Therr• are two conf1 gu.r.ations of the new "SENSJ.STOR" silicon resistor. The TM 1/4 is an axial lead molded device which is linearily derated at foll load from 100°C to I 50°C.

The TC 1 / 8 is encased in a TO-5 round-welded

package and is derated Linearily at foll load from 125°C to Z00°C.

Both units

are immediately available in commercial quantities in standard resistance ratings ranging from 100 to 1,000 ohms at 25°C. Texas Instruments is the leader in the field of silicon technology, having developed and pioneered the commercial production of silicon transistors in 1954.

This newest silicon semiconductor product is one result of Tl's

continuing re search and development in all fields of semiconductors and resistors.

In addition to the industry's widest line of silicon and germanium

transistors, Texas Instruments also manufactures a broad line of silicon diodes and rectifiers , "tan-TI-cap" solid tantalum capacitors, carbon film re sis tors, and high purity silicon material. -30-
