Title: Semiconductor devices and circuit arrangements
IPC: H01L27/07
Filed: 1969-06-13
Abstract: 1,255,976. IGFET. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13 June, 1969 [14 June, 1968], No. 30055/69. Heading H1K. In an IGFET the channel of which is defined by the gap between source and drain inclusions of N(P) type formed in the surface of a P(N) type substrate the gate electrode is connected to the substrate via a decoupling capacitance exceeding the capacitance of the drain PN junction and preferably also that of the source junction. Though a separate circuit element may constitute the capacitance it is preferably formed at the surface of the substrate. It may comprise a layer of dielectric disposed between the substrate and an overlying metal layer, a Schottky barrier between a metal layer and the substrate or a PN junction and the connection from the gate may consist of a diffused junctionisolated track or of a metal track on the substrate passivation. To avoid formation of a continuous surface conduction channel between the capacitor and the drain electrode the insulation under the metal track may be of increased thickness, have an overlayer of a second dielectric, or a more highly doped inclusion may be formed in the substrate at that point. The first of these measures is adopted in the embodiment shown in Figs. 1 and 2 where oxide 2 forms the capacitor dielectric. The device is made by diffusing phosphorus through genetic oxide masking to form source and drain regions 5, 6 in a boron doped epitaxial layer 4 on a heavily doped P-type Si wafer 3. The oxide masking is removed at the sites of the gate and capacitor and reformed to a smaller thickness after which gate and capacitor electrodes 7, 11 and connecting track 10 are formed by shape etching a layer of vapour deposited aluminium. When a Schottky diode capacitance is used these layers would be of gold or nickel. Where additional dielectric is used under the track it may consist of further layers of silicon nitride and oxide. These are initially deposited overall, the nitride by reaction of silane and hydrazine, and then the oxide is shape etched and used as a mask in etching the nitride. The devices may be made in multiple and later subdivided or used as elements of an integrated circuit.

Abstract: 1,193,835. Electro erosion. EXPERIMENTALNY NAUCHNO - ISSLEDOVATELSKY INSTITUT METALLOREZHUSCHIKH STANKOV. 6 July, 1967, No. 31205/67. Heading B3V. [Also in Divisions G3 and H2] In the electro-erosion machining of a workpiece 4 by an electrode tool 5, movable along a prescribed path relatively to the workpiece by a follow-up system 2, 3, the electrode and workpiece are fed with working current pulses from a pulse generator 6, and in the event of a short-circuit between the electrode and workpiece, current pulses of greater power are fed to the gap to remove the short circuit. The workpiece 4 is mounted on a table 1 movable in two directions by motors 2, 3 controlled by a feed system 10 and a gap measuring instrument 9. In the event of a short circuit in the gap, due for example to the accumulation of debris, the gap measuring instrument 9 stops the feed system 10 and actuates a master control 12. The latter opens switches 7, 8 to isolate the pulse generator 6 and measuring instrument 9 from the gap, and also actuates an auxiliary current generator 11 which supplies current pulses of increased amplitude to the gap for burning away the debris. After a predetermined time delay, a built in device stops the master control 12 and closes switches 7, 8 to restore normal machining operation. In a modification, Fig. 2 (not shown) the switches 7, 8 are omitted and the pulse generators 6, 11 are isolated from each other by a diode (13). In a further embodiment, Fig. 3 (not shown), the working current pulses are produced by a working capacitor (14) fed by a charging circuit (6<SP>1</SP>). These pulses are fed through a controllable thyratron (15) acting as a switch, to the primary winding (21) of a transformer (16). Secondary winding (17) of the transformer is normally connected across the gap. In the event of a short-circuit, the master control (12) switches the primary winding of the transformer across the gap and simultaneously reduces the pulse frequency.

Title: Automatic device for determining the true boiling point curve  of a composite substance
IPC: G01N25/14
Filed: 1974-07-16
Abstract: 1468548 Controlling distillation COMPAGNIE FRANCAISE DE RAFFINAGE 16 July 1974 [19 July 1973] 31386/74 Heading BIB [Also in Division G3] The boiling-point curve of a composite substance is automatically determined by a boiler and distillation column assembly controlled by a sequencer comprising an arrangement of logic circuits. As shown, a column 1, with heat insulation 2, has an internal packing a total reflux equivalent to two theoretical plates. A charge 4 to be distilled is heated, by a heater 5, in a flask 3. A condenser 6 produces a reflux and a solenoid 11 actuates a valve 10 to control draw-off of a distillate 20 to a vessel 19 through condensers 22, 24. A trap 28 containing acetone mixed with solid carbon dioxide condenses vapours which pass through the condenser 6. A solenoid valve 29 keeps the entire device at atmospheric pressure or at a reduced pressure by a pump 30 through a control valve 31. The determination of the boiling curve is effected in response to the flow-rate of the liquid at the column-head which occurs as drops from glass projections 13-12. The drops are sensed photo-electrically and a signal derived, via a frequency/voltage converter in a unit 16, for controlling the heater 5 in dependence on the flow-rate. The temperature at the column head is sensed by a platinum probe 9 and controls, through a unit 17, the draw-off rate by energising the solenoid 11, and, through a unit 18, the temperature in the condensers by adjusting a solenoid valve 40 directing cooling fluid from a line 34 to a line 35, or to a by-pass via line 41. The boiler-heating is controlled in dependence on the flow rate of the liquid at the column head by linear programming temperature with respect to time. The control system is embodied using FET switches, operational amplifiers and unijunction transistor relaxation oscillators triggering triacs.
