Patent number: 4712129Abstract: A semiconductor integrated circuit device includes a rigid planar member or cover affixed to and overlying at least a portion of the upper surface of a semiconductor integrated circuit bar. The upper surface of the planar member is textured to lock the member to the encapsulating medium, and has a thermal coefficient of expansion similar to that of the integrated circuit bar. According to another aspect of the invention the planar member is formed of a material having a low alpha particle emission.Type: GrantFiled: September 30, 1985Date of Patent: December 8, 1987Assignee: Texas Instruments IncorporatedInventor: John W.

Patent number: 4495376Abstract: A carrier having a plurality of leads extending from the lateral sides thereof. The leads extending along the lateral side and over protuberances into depressions in the bottom of the carrier. Each of the depressions is separated by ribs from the other depressions. The ends of the leads disposed in the depressions are prevented from substantial movement by the rib to prevent contact with adjacent leads. At least some of the leads are provided with holes disposed adjacent to the exit of the leads from the enclosure of the carrier. The holes in the leads allow the leads greater flexibility at their portions close to the entrance of the leads into the enclosure. The leads are tapered along their length toward the protuberances. Further, the leads are separated by a width along the lateral side which is within the range of slightly greater than the width of the leads to less than the width of the leads to prevent nesting.Type: GrantFiled: September 15, 1983Date of Patent: January 22, 1985Assignee: Texas Instruments IncorporatedInventors: Angus W. Hightower, Reginald W. Smith, John W. Orcutt

Patent number: 4463217Abstract: A surface mounted integrated (IC) device package or carrier is disclosed suitable for accommodating large terminal count IC devices in a small space. A carrier, preferably of plastic, is disclosed having notches or castillations in its sides. A first row of leads are positioned in the periphery of the package and a second row of leads are positioned in the notches, said notches formed a predetermined distance from the periphery of the package (e.g., 0.050"). Selected leads of the second row are alternated with said first row of leads. In the preferred embodiment, the first and second leads are separated by 0.025". Also in the preferred embodiment, the first and second row of leads extend over protuberances into depressions in the bottom of the package. Each of the depressions is separated by ribs from the other depressions such that the ends of the leads are disposed in the depressions and are prevented from substantial movement, thereby preventing contact with adjacent leads.Type: GrantFiled: September 14, 1981Date of Patent: July 31, 1984Assignee: Texas Instruments IncorporatedInventor: John W.

Patent number: 4260862Abstract: A pressure responsive electrical switch uses precalibrated snap acting monometallic or bimetallic discs freely disposed in a disc seat formed on a base member. Over pressure protection in the form of a surface spaced just beyond the normal snapped position may be provided to avoid calibration changes. A flexible thin gasket is positioned over the disc and is sealed to the base by trapping between the base and a cap which is clamped to the base. Several seal variations are shown to provide varying degrees and types of seals. A rocker member having a specially curved surface rests on a movable contact arm and transfers motion from the disc to the movable arm. A support for the movable arm has a portion which is formed with a complementary curved portion which cooperates with the rocker member and a stationary contact to limit the amount of stress imparted to the movable contact arm.Type: GrantFiled: February 21, 1979Date of Patent: April 7, 1981Assignee: Texas Instruments IncorporatedInventor: John W. Orcutt

Patent number: 4121073Abstract: An electrical switch actuatable upon the occurrence of a preselected level, includes a generally cup shaped, open ended housing which mounts therein a spaced pair of stationary contacts. The housing has two pairs of upwardly extending channels in its side walls, the two channels of the first pair aligned with the stationary contacts and the two channels of the second pair aligned with platform surfaces. An electrically conductive, flexible cruciform element is disposed in the housing with the distal end portions of two legs of the cruciform received respectively in the two channels of the first pair, and the distal end portions of the other two legs of the cruciform received respectively in the two channels of the second pair and resting on the platform surfaces. The stationary contacts may be disposed above or beneath the cruciform element for a normally open or normally closed switch as desired.Type: GrantFiled: February 28, 1977Date of Patent: October 17, 1978Assignee: Texas Instruments IncorporatedInventors: Thomas Bileski, Joe W.

Patent number: 4100930Abstract: A one-shot pressure relief device which can be hermetically sealed comprising a housing with a port fitting for connecting to a pressure zone to be monitored, the fitting having a passage which leads into a central cavity within the housing from the top side. The cavity is divided and sealed into two portions by a thin metallic membrane fixedly mounted adjacent a snap-acting pressure disc member with a central aperture. A hollow puncture member is positioned in the bottom of the housing in axial registry with the center aperture of the snap-acting pressure disc so that upon an over pressure condition in the monitored zone, the disc will snap over center at a predetermined condition allowing the membrane to move likewise piercing itself on the puncture member thereby venting and relieving the over pressure condition.Type: GrantFiled: May 3, 1976Date of Patent: July 18, 1978Assignee: Texas Instruments IncorporatedInventor: John W.

Patent number: 3988943Abstract: This invention relates to improved apparatus for the automatic calibration of cables of the type having a core wire and surrounding sheath. Such cables are commonly used in automobiles to transfer motion from a controlling member to a controlled member at a distant point which is moved in accordance with the force applied at the first member. A calibration apparatus is described which is fixedly attached to the cable sheath and comprises a rack section and a comb section which interact when force is applied to change the sheath length to that desired.Type: GrantFiled: February 19, 1974Date of Patent: November 2, 1976Assignee: Texas Instruments IncorporatedInventor: John W.

Patent number: 3961749Abstract: A thermally responsive valve assembly comprises a plurality of fluid ports in which typically two are connected to vacuum sources, one to vent and another two to control functions. The switching of the control functions from vacuum to vent and back again is controlled by a bimetallic coil which rotates and, in turn, causes a switch disc to rotate thereby changing the passage route between the ports from vacuum to vent or visa versa.Type: GrantFiled: January 10, 1975Date of Patent: June 8, 1976Assignee: Texas Instruments IncorporatedInventor: John W.
