Title: High Power Transistors.
IPC: H01L23/488
Filed: 1967-11-06
Abstract: 1,163,637. Transistors. WESTINGHOUSE ELECTRIC CORP. 6 Nov., 1967 [16 Nov., 1966], No. 50277/67. Heading H1K. In a high power transistor the base contact is replaced by an auxiliary emitter region on the side of the collector zone remote from the base zone. Base current is injected through the collector from this region and in the preferred arrangement, in which a number of interconnected emitter regions are distributed over the collector zone, this has the effect of eliminating the lateral voltage gradient in the base zone responsible for current crowding at the edges of the emitter. In a typical embodiment (Fig. 1) such emitters are formed by alloying strips 18 of aluminium, gold-boron or gold-silicon alloy to one face of an NPN sandwich formed by donor diffusion into a P-type wafer. Alternatively they are made by diffusion from boron chloride vapour through slits in silicon oxide masking. The " of the transistor proper is about 0-9 while that of the control transistor configuration constituted by the auxiliary emitter and the collector (base) and base (collector) zones proper is chosen to be less than 0À8 to ensure uniform distribution of the base current over the collector junction. In operation the control signal, which is applied between the auxiliary emitter and collector electrodes is fed from the main power source via a switching transistor. In a modification, in which a further PN junction is formed between the auxiliary P-type emitter and a further N-type zone, the power source is connected through this junction when it is broken down by a control signal applied across it.

Title: Method and apparatus for digital measurement and control
Inventor: PORTER LAWRENCE C
IPC: G05D11/13
Filed: 1969-10-17
Abstract: 1291840 Automatic control of speed UPJOHN CO 17 Oct 1969 51181/69 Heading G3R [Also in Division G4] Variable frequency signals representing different parameters, e.g. the speeds of D.C. motors driving pumps for supplying different constituents of a mixture, are each compared with a corresponding pre-set value to derive digital difference signals for adjusting the parameters. The motor speed may be adjusted by a stepper motor 11, Fig. 1 which receives a train of pulses representing the measured difference, and adjusts a potentiometer 10 connected to an SCR controller. Magnetic teeth on a gear 5 may be sensed by a pick-up 8 and a frequency converter 9 provides an output said to be representative of transfer rate rather than motor speed. Scanner 26, Fig. 5 processes the pulses on inputs 12 to 23 so that corresponding pulses appear on outputs 32-43 but without coincidence between pulses on different outputs. The control system is under the general control of a step counter 162 which enables gating network 160 to sample leads 32-43 sequentially. Pulses representing the resin input 32 are applied to period counter 168 in each sampling period, an output 243 being obtained after a pre-set number e.g. 1000 has been counted. Each sampled input 33-43 is counted at 170 and compared at 172 with a corresponding pre-set value 202-212 representing the desired ratio of the associated constituent to resin. Comparator 182 controls an error counter 180 to count constituent pulses during the interval between the outputs from 243 to 172, the direction of counting being determined by which output is the first to occur. The ratio error accumulated in counter 180 is converted by multiplier 178 into a train of pulses representing the mass transfer rate error, and these pulses are applied to the appropriate stepper driver 221-231. In a further sequence step, the total material throughput rate is checked. Gating circuit 160 supplies the pulses on all leads 32-43 to stages of counter 170 corresponding to the effective weights of the pulses. Clockpulses from source 161 are fed to period counter 168 to establish a selected time interval e.g. 1 second, and a comparison between actual and desired total throughput rates is made at 172. Error counter is controlled by comparator 182 as before, but in this step counter 180 accumulates pulses from the stage of counter 170 corresponding to the effective weight of the resin pulses multiplier 178 then derives the portion of this error which is attributable to the base constituent (resin) and produces a pulse train output for adjusting stepper 220.

Abstract: 1,134,659. Transistor bi-stable circuits. MOTOROLA Inc. 13 Nov., 1967 [7 Dec., 1936], No. 51612/67. Heading H3T. A JK flipflop comprises: a slave bi-stable circuit 7 and a master bi-stable circuit 9 so arranged that the outputs Q M , Q M  of the master are fed as inputs to the slave, and the outputs Q s , Q s  of the slave are fed as inputs to the master; means for feeding J and K inputs to the master 9; and a clock pulse control 6 which locks the master and enables the slave when the clock pulses are at one logical level, and which locks the slave and enables the master when the clock pulses are at the other logical level. Assume initially that the potential Q s  is low and potential #Q s  is high, then when clock pulse C switches to its low level Q s  switches on transistor 78 to enable the J input. If J is at a high level transistors 68, 56 conduct to make #Q M  low. If J is low, transistors 74, 58 conduct and Q M  is low. If J and K inputs are both high together, then, assuming Q s  is high, a low level clock pulse will again switch on transistors 68, 56 to make #Q M  low and transistors 72, 74 will be off to make Q M  high. The next high level clock pulse will switch the slave to Q s  high and Q s  low, switching on transistor 76 instead of transistor 78, so that on the arrival of the next low level clock pulse the K input will control the master bi-stable circuit switching it to Q M  low and #Q M  high. At the next high level clock pulse transistor 32 overrides transistor 16 and the slave switches to #Q s  high and Q s  low. Separate set S and reset R inputs are also provided to give independent control of the states of the master and slave circuits. The various transistors are biased from a circuit 8 which includes temperature stabilizing diodes 96, 98.

Abstract: 1352114 Blasting PENNWALT CORP 13 Nov 1972 [26 Jan 1972] 52381/72 Heading B3D [Also in Division H1] An abrading apparatus for producing miniature electrical resistors comprises a work-table 16 mounted for movements in a horizontal plane and having a plurality of holding zones each adapted to support a workpiece 14, a vertically disposed nozzle 12 mounted above the worktable for directing a pressurized abrasive stream downwardly towards the work-table, means for supplying the stream to the nozzle, means for indexing the work-table so that one of the holding zones is directly beneath the nozzle, and means for initiating the flow of the abrasive stream from the nozzle. The nozzle 12 is enclosed in a hood 13 which is connected to a vacuum source for removing spent abrasive and residue from the workpieces. As described, the work-table 16 has two holding zones defined by pins 38, the workpieces being held on the table by vacuum means. The table is indexable through 180 degrees first in one direction and then in the opposite direction so that while one workpiece is being abraded in one zone, an abraded workpiece can be replaced by a new workpiece in the other zone. The indexing of the table is effected by rotation of a pinion 69 engaged by a rack on the position of a pneumatic cylinder 24, the indexed positions being determined by engagement of an abutment 28 with one or other of stops 30, 32 a, button 34, in the indexed positions of the table, operating one or other of two pairs of switches 51, 53 or 52, 54. The table can be moved in two perpendicular horizontal directions on a slide 26 to position the workpiece beneath the nozzle. The workpieces initially have a resistance less than their desired resistance and during abrading probes 18 are lowered by a pivoted arm 20 to engage and measure the resistance. The resistance increases during abrading until, at a predetermined value, the abrading is automatically terminated by operation of a pinch valve in the air supply to the nozzle. In one embodiment, the apparatus is manually controlled and separate switches are actuated to effect indexing and abrading. In an alternative embodiment, abrading is effective automatically after indexing.
