Filed: 1975-10-07
Abstract: 1517203 Transistor circuits INTERNATIONAL BUSINESS MACHINES CORP 7 Oct 1975 [21 Nov 1974] 40907/75 Heading H3T An on chip field effect transistor circuit is disclosed for electrically compensating for variations in process parameters which have occurred during the course of fabrication of the integrated circuit chip as well as variations in environmental parameters such as supply voltages and temperature. The compensation is performed by utilizing three field effect transistor devices on the integrated semiconductor chip as a sensor to detect variations in the characteristics of the devices due to deviations in the process parameters during fabrication thereof. The sensing field effect transistors operate in a circuit to adjust the gate potential of FET load devices in those functional circuits on the integrated circuit chip whose sensitivity to the variations in the process parameters is critical to the operation of the circuit as a whole. In the described circuit, the gate width of transistor T1 is made less than that of any other transistor in the circuit and the gate length of T2 is similarly less than that of any other. The circuit produces a voltage V LG  dependent on the transistor parameters.

Title: Improvements in or relating to semiconductor devices
IPC: H01L27/10
Filed: 1963-10-17
Abstract: 1,010,142. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 17, 1963 [Nov. 23, 1962; Dec. 14, 1962], No. 40963/63. Heading H1K. A semi-conductor device includes a monocrystalline body having at least three regions defining two spatially separated junctions, one of which can emit recombination radiation which may be absorbed by the other with the emission of charge carriers, and electrodes connected to each of at least three of said regions. In one embodiment, Fig. 1 (not shown), the device is a simple PNP structure comprising N-type GaAs with Zn diffused into it to form the P-type regions and having a forward biased emitted-base junction which produces recombination radiation which, falling on the collectorbase junction, causes the emission of charge carriers to provide the collector current. In a modification, Fig. 3, the light emitting and absorbing junctions are on the same side of the base. Thus, a wafer 20 having N and P regions has a trough 24 etched in the N region to form a circular region 28 and an annular region 29, the junction of the former with the P-region being the light emitting junction and that between the latter and the P-region being the light absorbing junction. Some of the light transmission is direct, and the remainder by reflection from a metal coating 30. To avoid short circuiting the junction, the coating must be broken at this point, or alternatively the body may be covered with an insulating coating prior to adding the metal coating. In an alternative embodiment, Fig. 4, a forward-biased radiation emitting junction 38 is also provided on the collector side. Thus, collector current passing through this junction causes the emission of light to the radiation absorbing junction 37 in addition to that received from the emitter junction 36 so causing increased collector current. The device may be constructed by taking a P-type wafer of GaAs doped with Zn, growing epitaxially by vapour deposition N-type regions on each side of GaAs doped with Te, and finally diffusing zinc into the surface layer, so forming a PNPNP structure from which one of the P-type surface zones is then removed. Fig. 5 illustrates an embodiment working on similar lines, in which a PNP structure is obtained by diffusing Zn into an N-type wafer, and etching to produce a recess 45, which separates emitter from collector regions, a reflecting coating 48 being provided for the radiation from the junction 46. The collector contains a radiation emitting junction as in Fig. 4. Other modifications mentioned include (a) the use of a radiating junction in the collector region only, a conventional transistor configuration being used at the input, (b) the omission of the emitter region 32, Fig. 4, the radiation falling on the junction 37 from an external source, (c) the use of a tunnel diode junction for the base-emitter junction, (d) the use of structures having multiple collectors or emitters.

Abstract: 1,143,057. Fluidic pulse shapers. HONEYWELL Inc. Sept. 8, 1967 [Sept. 9, 1966], No.41125/67. Heading G3H. A fluidic pulse shaper comprises cascade connected proportional amplifiers 11, 12, 13 in circuit with resistances 36, 37, 44, 50, 52, 55, 61, 63, 65, 68, 70, 72, 74, 76 between a constant pressure source P 1 , an outlet 60 which is subjected to variable pressure P 5  and an outlet 40 from which fluid issues at two different pressures P 4  (see also Fig. 3 not shown) determined by whether the rate of flow through resistance 61 is sonic or not. When the flow through resistance 61 is sub-sonic P 3  exceeds P 2 , due to the effect of resistances 50, 51 for all values of P 5 , and thus a major flow is established through legs 17, 24 and 28 to output 40, but once the flow through resistance 61 becomes sonic, any reduction in P 5  has no effect upstream of that resistance while P 3  is reduced. At the stage when P 3  falls below P 2  the major flow is switched via legs 18, 23, 29 so that P 4  drops to its lower value. Resistance 61 is of orifice type. The apparatus may be used in an aircraft automatic flight control system with outlet 60 subjected to atmospheric pressure.

In a thermal regenerator, an annular space containing the heat transfer material is formed between two concentric cylinders 12, 13, and is divided by radial walls 14 into sectors, e.g. 34, which are sub-divided into trapezoidal subchambers by radial and arcuate partitions, e.g. 35-38 and 59, which sub-chambers are filled with heat exchange material, the regenerator being characterized in that the cylinders 12, 13, radial walls 14 and radial partitions, e.g. 59, are all of common axial length and terminate in the parallel end faces of the regenerator whilst the arcuate partitions, e.g. 35-38 are of lesser axial length and lie wholly between the end faces, thus reducing the total length of edges at the ends of the regenerator which need to be constructed for sealing contact with the gas ducts which sweep over the ends of the regenerator. The arcuate partitions may be continuous or discontinuous over their axial lengths. The heat exchange material may be retained in their sub-chambers by grids 41 formed of bars inclined to the arcuate partitions and co-planar with the end faces of the regenerator.

Title: Production of beryllium hydroxide
Inventor: J MORANA SIMON
IPC: C01F3/00
Filed: 1963-10-28
Abstract: Commercial beryllium hydroxide is purified by forming therefrom a solution containing beryllium sulphate and impurities other than silica and alkaline each metal fluorides, adding to the solution a chelating agent to retain in solution the said impurities and adding ammonium hydroxide solution to precipitate beryllium hydroxide. Suitable chelating agents are the tetrasodium salt of EDTA, diethylene triamine penta-acetic acid and trisodium hydroxyalkyl ethylene diamine triacetate.  The beryllium sulphate solution may be prepared by introducing a slurry of the commercial beryllium hydroxide continuously into excess concentrated H2SO4 over such a period of time as to reach a temperature of 300 DEG  F., thereby eliminating the conventional baking step, filtering the reaction liquid to remove silica and alkaline earth fluorides, diluting the filtrate with de-ionized water and adjusting to about pH 3 with ammonia.  Alternatively, commercial beryllium hydroxide is reacted with 50% excess concentrated H2HSO4, the reaction mass is baked at about 260 DEG  F. for about 3 hours, the baked mass is diluted with de-ionized water, silica and alkaline earth metal fluorides are removed by filtration and the filtrate further diluted is adjusted to pH 3 with ammonia. After addition of the chelating agent, the pH is adjusted to pH 6.5 with ammonia, the solution is boiled, the pH again adjusted to pH 6.5 and filtered to obtain substantially pure beryllium hydroxide.
