Filed: 1970-06-12
Abstract: 1283484 Light activated PNPN switch WESTINGHOUSE ELECTRIC CORP 12 June 1970 [20 June 1969] 28563/70 Heading H1K Instantaneous turn-on of a light controlled PNPN switch is achieved by providing, at the face of the semi-conductor body opposite to that on which light is incident, means for reflecting the light back into areas of the body not illuminated in the first transit. In the device illustrated in Fig. 2 the reflective means is a concentric series of grooves 50 inclined at an angle of >16-5 degrees to the lower surface of the silicon body. This ensures total internal reflection when using radiation from a neodymium doped laser 42. A single groove may alternatively be used in which case its intersections with the PN junctions in the body must be passivated. Preferably to improve reflection aluminium is evaporated over the surfaces of the body abutting the copper electrodes and sintered at 500‹ C. for 20 minutes.

Abstract: 627,713. Granulating. LAZARENKO, B. R., and LAZARENKO, N. J. Sept. 24, 1946, No. 28583. [Class 82(ii)] In a method of producing powders of metals, alloys or other electrically conductive materials, the said materials serve as electrodes in an electric oscllatory discharge circuit so adjusted as to operate in the region of spark discharges, the electrodynamical forces liberated by the said electric spark discharge at the moment the said oscillatory circuit is closed as a result of a low-voltage breakdown of a liquid dielectric between the said electrodes removing particles of the material being pulverized and ejecting them into the surrounding liquid medium serving as a dielectric. The electric oscillatory circuit may be made to give a spark discharge by varying the electric parameters of the oscillatory circuit. In the form shown a disc 2 of the material acting as cathode is rotated in a liquid in a vessel 1 by a motor 8, a disc 3 of the same material acting as anode carried by a movable carriage 6 being then forced to rotate when the spark discharge commences and kept rotating; liquid medium is circulated by a pump 7 and the powdered material thus removed in a known manner. While the discharge takes place, the armature of the relay 4 is attracted to the poles by the discharge current passing through the windings. As soon as the discharge ceases the armature is released and closes a contact in an auxiliary circuit containing a motor 5 which moves the carriage 6 carrying the disc 3 towards the disc 2 and the discharge recommences. The anode may be in the form of a plate having a smooth or serrated edge arranged parallel to the axis of the cathode and mechanically oscillated in a direction parallel to this axis.
