Title: Semi-conductor devices and methods of making them
IPC: H01L21/225
Filed: 1955-03-04
Abstract: 804,000. Semi-conductor devices. RADIO CORPORATION OF AMERICA. March 4, 1955 [April 1, 1954], No. 6499/55. Class 37. Surface recombination of charge carriers in a body of semi-conductor material to which a plurality of contacts are made is reduced by providing the body with a layer of relatively high conductivity semi-conductor material having low lateral conductivity after the electrodes have been affixed. The junction transistor shown in Fig. 5 is formed by diffusing indium from pellets 26, 28 into an acid-etched N-type Ge wafer 22 to form emitter and collector PN junctions 30, 32 and soldering on a non-rectifying nickel contact 38. The assembly is then etched in a solution of bromine and hydrofluoric and nitric acids and a film of acceptor impurity, e.g. In, Zn or Al about 10 Š thick is evaporated on and heated to provide a P-type surface layer. Alternatively a surface layer of high-conductivity N-type material may be provided by evaporation and diffusion of As, Sb or Bi. In either case the impurity layer may be.provided by dipping the body in a solution containing impurity ions, e.g. dilute copper nitrate instead of by evaporation. In an alternative embodiment a discontinuous surface layer is provided by heating an evaporated on layer at a relatively low temperature for a longer period, causing coagulation of the impurity into minute blobs. In this case thicker impurity layers may be used but should not exceed 500 Š. Silicon, aluminium antimonide or indium phosphide may be used instead of germanium as the semi-conductor material.

Abstract: 1,127,955. Fuel cell electrode. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 13 Feb., 1967 [14 Feb., 1966 (3) ; 13 April, 1966 (3)], No. 6855/67. Heading H1B. The invention comprises a gas electrode comprising an active layer of carbon powder held together with a binder and a pre-formed porous film of fluorocarbon resin. The carbon powder may be activated and may contain a metal catalyst, e.g. it may be saturated with chloroplatinic acid solution. It may be waterproofed by treatment with paraffin wax, a fluorocarbon resin or polystyrene. The binder may be a synthetic resin, e.g. polystyrene or a fluorocarbon resin and may be applied in a solvent, e.g. benzene. The fluorocarbon may be P.T.F.E. or a copolymer of tetrafluoroethylene and hexafluoropropylene. The electrode may be assembled by applying a coating of the carbon-binder mixture on the film or by assembling the layers in a metal mould and compression moulding them. In either case they may subsequently be heated to remove solvent. In particular embodiments of the invention: (a) a layer of powdered, waterrepellant synthetic resin, e.g. fluorocarbon resin is attached to the face of the fluorocarbon resin film opposite the carbon layer, (b) a second film may be placed on the other side of the powdered layer of (a), (c) a layer of fluorocarbon powder is sandwiched between the active layer and the fluorocarbon film, (d) a current collector is sandwiched between the active material and the film, (e) the film is sandwiched between two layers of active material and (f) the current collector may be embedded in the active layer. The current collector may be a silver grid with a nickel terminal or a nickel wire mesh. The electrode may be used in a fuel or air depolarized cell. In a particular embodiment an air/ McOH cell comprises an air electrode 1, supported on the gas side by piano wires 7, a fuel electrode 3 containing a noble metal catalyst on a Ni plaque and having a terminal 4, and an inlet 5 and an outlet 6 for fuel/electrolyte mixture.

Abstract: 525,903. Photographic roller blind shutters. LEITZ GES. E. March 2, 1939, No. 6906. Convention date, June 2, 1938. Addition to 488,073. [Class 98 (i)] The shutter of the parent Specification is provided with improved means for braking the initial and final movements of the leading blind, comprising a cam, driven by said blind, and operating a brake, preferably of the internally-expanding type, acting on one of the wheels of the shutter mechanism. As shown, on the spindle 16 of the leading blind V<SP>1</SP> is a disc 1 having a projecting cam 2 and a snail cam surface 3. The brake is housed in a pinion 42 in the gear train between the spindle 16 and the take-up spool 19 of the film, and comprises an annular brake-drum 6 having a pin 7 engaging loosely in a slot 8 in the pinion, thereby permitting limited play between drum and pinion to facilitate winding of the shutter. The drum contains brake-shoes 9, 10, anchored by a pin 12 to the camera body 13, which shoes are expanded by a flat pin 11 on a lever 14 carrying a roller 15 engaging the disc 1. The shutter is set by the usual knob 22, and when released by depressing the button 29 to disengage the coupling 27, 28, the cam 2, by rocking the lever 14, turns the pin 11 to expand the shoes 9, 10 and thus checks the initial speed of the leading blind. During further movement of this blind, the cam surface 3 engages the roller 15 and the brake is again applied gently to eliminate shock as the blind completes its movement. The cam described may also be employed to co-operate with a spring-controlled brake-lever of the kind shown at 22 in Fig. 11 of the parent Specification.

Abstract: 799,012. Tractor power-take-off mechanisms. MASSEY-HARRIS-FERGUSON, Inc. March 9, 1955 [March 30, 1954], No. 6916/55. Class 79(2) Relates to a tractor having a power-take-off shaft which may be driven either at a speed directly and constantly proportioned to the speed of the tractor engine or at a speed directly and constantly proportional to the ground speed of the tractor. As shown in Fig. 1, the crankshaft S of the engine (not shown) drives a pair of coaxial clutches 16, 16<SP>1</SP>, the clutch 16 driving, through a shaft 17, changespeed gearing 19, transmission shafting 20, 21, 22, differential gear 12 and axle shafts 13 of the rear wheels 11 and the clutch 16<SP>1</SP> driving, through a tubular shaft 18, coaxial with the shaft 17, a gear 36, meshing with a gear 37 on a shaft 38 coaxial with the tubular lay shaft 39 of the gearing 19. The shaft 38 drives a pump 26 of the customary tractor hydraulic system which includes a power-lift ram 27. Referring to Fig. 2, the pump shaft 40 is coaxial with the power-take-off shaft 35. Slidably engageable with the splined adjacent ends of the shafts 35, 40 is a combined gear and clutch assembly 55, comprising an internally splined hub 56 and gear wheel 62. A circumferential groove 72 on the assembly 55 is engaged by a finger 71 on an arm 70 secured to a shaft 66 rotatable by a hand lever 65. A segment 74 integral with the arm 70 is provided with three depressions to coact with a spring-urged detent carried in a tubular casing boss 75, whereby the assembly 55 may be moved into any of three positions. In the full line position shown in Fig. 2, the shaft 35 is at rest. When the assembly 55 is moved to the right the internal splines of the hub 56 engage the splines 58 of the shaft 40, so that the shaft 35 is driven by the clutch 16<SP>1</SP>, shaft 18, gears 36, 37, shaft 38 and pump shaft 40, at a speed proportional to that of the engine. When the assembly 55 is moved to the left in Fig. 2 the gear wheel 62 engages a gear wheel 63 secured on the transmission shaft 21, so that the shaft 35 is then driven from the output shaft 20 of the change-speed gearing 19 at a speed proportional to the ground speed of the tractor. In a modification the combined spline clutch and gear assembly is disposed between the pump and shaft 38 and the gear wheel of the assembly meshes with a gear wheel on the shaft 20
