Title: Transistors
IPC: H01L21/00
Filed: 1958-07-23
Abstract: 863,740. Transistors. HUGHES AIRCRAFT CO. July 23,1958 [Aug. 2, 1957], No. 23771/58. Class 37. In a junction transistor an auxiliary electrode is provided on the emitter zone in addition to the terminal electrode for establishing a potential gradient in the emitter region parallel to the emitter junction, to control the emission from the region. In the embodiment, Fig. 1a, the emitter region 3 is provided with an electrode 9 at its centre and an annular electrode 13 at its periphery. If a forward bias is applied to connection 9 and a reverse bias to the peripheral connection the emitter current is confined to the central part of the emitter. The resultant decrease in surface carrier recombination results in a higher current gain which falls off only slowly with increasing current. If the reverse bias is applied to the central connection and the forward bias to the peripheral connection emitter current is confined to the peripheral part of the emitter where it has a maximum effect on the base resistance. The device may be made from a wafer 5 of N-type silicon cut from an ingot grown in an antimony doped melt by alloying pellets of aluminium to its opposite faces to form a regrown P-type emitter region 6 and a larger regrown collector region 7. The aluminium overlying the regrown emitter region with the exception of a peripheral part 13 and a central dot 9 is removed by etching with hydrochloric acid through a wax mask, or by grinding. A nickel base tab or ring is then soldered to the edge of the wafer. The invention is also applicable to NPN, PNIP and NPIN transistors. Germanium, gallium arsenide, gallium phosphide, indium arsenide, indium phosphide, indium antimonide or gallium antimonide may be used instead of silicon.

Abstract: 794,719. Electric tests. LYKKE, G. Aug. 24, 1954, No. 24627/54, Class 37. Apparatus for testing the wound rotor of a D.C. machine comprises a magnet producing a narrow diametric magnetic field across the rotated armature, and a pick-up coil disposed symmetrically with respect to the rotor and the field so that with a good rotor winding equal and opposite E.M.F.'s are induced in the coil except for the small variations due to the slots in the armature, but a fault in the armature winding produces a large change in the coil voltage. As shown, Figs. 1, 2, the rotor mounted with its shaft 10 in bearings 8, 9, is located between the poles 3, 6 of a magnet 1. The pick-up coil 7, which has a U-shaped core, is also mounted symmetrically, and its output is taken to a C.R.O. whose time base is derived from an alternator driven synchronously with the shaft 10. A short-circuited turn on the armature, or a reverse-connected turn, is shown on the C.R.O. by characteristic signal pulses, which may be confirmed by the voltage output from two brushes 15, 16 in contact with adjacent segments on the commutator 11, and which may alternatively be connected to the C.R.O. The brushes 15, 16, which also give a characteristic indication for an open-circuit turn on the armature, are mounted on an adjustable carrier 14 to allow them to be located on the segments giving maximum voltage. The stator of the alternator providing the time base for the C.R.O. is rotatable against a dial, so that the position of the faulty turn on the rotor may be located. When applied to rotors wound for more than two poles the magnet polepieces 3, 6 are disposed at adjacent N, S poles, e.g. for a four-pole rotor, the poles 3, 6 are 90 degrees apart.
