As shown, Fig. 3, a circular wafer 10 of N-type Si, which may be cut from a rod pulled from a donor-doped Si melt and lapped and/or etched, or may be cut from a dendrite prepared as described in Specification 913,674 is disposed in a diffusion furnace of maximum temperature 1100-1250‹ C. in the vapour of an acceptor material, such material being maintained at 500-1250 C., in an example, Ga vapour is diffused into the flat parallel faces of the wafer at a maximum temperature of 1200‹ C. to produce P-type regions 18, 20. A collector contact 34 and a base contact 30, each of acceptor metal or an alloy thereof, e.g. Au-Ga, Ag-Sn-In, Ag-In (90: 10%), or preferably Au-B (99: 1%), are placed on opposite faces of the wafer (in an example the collector contact 34 is placed on a Mo disc), an annular emitter contact 32 of donor metal or an alloy thereof, e.g. Au-As, Ag-As, Ag-Sb, or preferably Au-Sb (99.5: 0.5%) is placed around base contact 30, and the contacts are fused to the wafer by heating in a vacuum of 10<SP>-2</SP> to 10<SP>-5</SP> mm. Hg or an inert atmosphere, e.g. at 750‹ C. for 15 minutes. The emitter annulus is then partially masked with wax, rubber, or resin, and etched with aqua regia and then with a mixture of HNO 3 , HF, and acetic acid to form a plurality of discrete wedge-shaped emitter regions as shown in Fig. 6; alternatively, the emitter regions may be circular, elliptical, rectangular &c., and may be formed by fusing a plurality of individual foils to the wafer. Metal, e.g. Cu or Ag, contacts are fused to the emitter regions and leads are joined thereto and to base and collector contacts. In a modification in which a row of emitter regions are formed on a rectangular wafer, two or more base contacts are provided. In operation, all emitter-collector paths become conductive when any one is fired, and remain conductive until all are rendered non-conductive simultaneously. A suggested application is for checking rocketry components during count-down. The semiconductor wafer may be of Ge, SiC, or a III-V compound such as GaAs, GaSb, InAs, InSb. Specification 913,674 is referred to.

Abstract: 120,782. Efandem Co., and Williams, A. H. Nov. 26, 1917. Battery lamps. - In a portable lamp, the bulb holder is mounted in an insulating carrier, on which is mounted a conducting part connecting the bulb holder to an insulated switch contact on the outer face of the metal casing. The insulating carrier may be a plate A, provided with a metal rim a soldered to the casing. Between the insulating plate A and the shoulder of the bulb holder is clamped the conducting plate D. In one construction, an insulating washer E is held in a gap in the insulating plate by a bifurcated rivet F, one prong of which enters a hole in the edge of the disk, while the other bears on the surface of the metal plate D. The head of the rivet, which is concentric with a larger aperture of the casing, forms the stationary contact of a sliding or press switch G, In another construction, a long metal strip attached to the metal plate D passes through a notch in the insulating plate and along the inside of the casing between strips of insulating material. The end of the strip is held by a contact-rivet passing through an insulating washer which is let into a hole in a strengthening band surrounding the casing. Tangs on the metal plate enter the insulating disk, to retain the plate when the bulb-holder is removed.
