Title: Semiconductor devices
IPC: H01L23/467
Filed: 1953-11-18
Abstract: 760,708. Semi-conductor device. RADIO CORPORATION OF AMERICA. Nov. 18, 1953 [Nov. 29, 1952], No. 31984/53. Class 37. A semi-conductor device comprises a body of semi-conductor material with zones of different conductivity type, with a duct of good thermalconductivity and adapted to carry a fluid coolant in heat transfer relation with one of said zones. In the Fig. 5 device, a cylinder of N- type Ge is formed by grinding or preferential etching into a spool 31. A hole 38 is formed by heating a metal rod, at the end of which is carried a body of activator material of acceptor type which is melted by the heat and dissolves the Ge so that pressure applied to the rod forces it through the body while the activator alloys with the internal surface to convert annular zone 48 to P-type. Suitable impurities are gallium, which is normally liquid, indium, aluminium, zinc or even boron which, having a higher melting point than Ge must be dissolved in a neutral or other acceptor impurity. Alternatively, a hollow tube filled with the impurity may be used. The inner surface is then chemically etched and into the hole is inserted a Cu or Ni tube 46 coated with Sn or In 47 which is heated to fuse it to the inner surface. The outer surface of the recessed part is wrapped either with an In foil which is heated to diffuse it into surface zone 50 after which cooling tubes are fused thereto or else indium coated tubes may be used. Simultaneously, tinned tubes are fused to the ends 34, 36 of the spool. The four sets of cooling tubes 46, 52, 56, 58 which are connected in parallel or series to a coolant supply serve as electrodes and 56 and 58 may be electrically connected, whereas the others, which carry insulating fluid, such as distilled water, are joined by insulating pipes. The whole assembly may be encased in insulating material such as that known by the Registered Trade Mark " Araldite." In a rectifier (Fig. 7, not shown), the central P-N junction is formed as above and a copper tube inserted, while the other electrode consists of a tinned coolant duct of elongated cross-section fused to the recessed part of the reel. In another arrangement a main semi-conductor body is bonded to a copper annulus and the electrodes which are blobs of activator material partly diffused into the main body to form P-N junctions are connected to copper discs, the discs and annulus being cooled by fluid flowing in series or parallel through tubes mounted on the peripheries thereof. In a modification, Fig. 4, one disc is replaced by a solid Cu cylinder 27 with a surrounding coil 30, which is fixable to a chassis 26 via an insulating layer 29 by an insulating bolt 28. In all the embodiments the basic body may be P-type and the N-type regions produced by diffusion of As, Sb, Bi or P.

[Also in Division F2] A percussive tool comprising a barrel 10 in which a piston 14 is slidable within a floating ram 11 so as to provide a chamber 16 wherein air is subjected to compression or rarefaction depending upon the direction of movement of the piston, with primary venting means 17 provided for venting the air in the chamber, has a sealing ring 21 loosely disposed in a groove 20 in the piston and so arranged in the groove that the air entrapped under pressure exerts an outward radial force on the sealing ring and the entrapped air is momentarily vented through the groove 20 during periods of reversal of the reciprocating movement of the piston. The sealing ring 21, of resilient material, is provided with an internal diameter which is greater than the diameter of the groove 20 so that when e.g. the piston is moved towards the right as shown in Fig. 4, the ring is forced into contact with the wall 22 of the groove and the air also acts on the inner diameter of the ring to force it into firm contact with the wall of the ram 11. Upon reversal of the piston at the end of the stroke, the sealing ring dwells momentarily in relation to the piston thus providing a passage through which the compressed air can escape. The primary venting means formed by the relation between the width of the piston 14 and the width of a recess 17 is fully described in Specification 932,275. A coupling device 18, 19 for preventing hammering of the piston and ram when the sealing ring wears out is fully described in Specification 932,224.

Filed: 1952-12-19
Abstract: 713,729. Photographic image-transfer apparatus. KODAK, Ltd. Dec. 19, 1952 [Dec. 21, 1951], No. 32290/52. Class 98(2) A photographic image-transfer apparatus for use in the process of Specification 655,274 comprises a container for processing liquid, said container having an opening for inserting an exposed sheet, supporting means external of the container for an image-receiving sheet, and a pressure device (e.g. a roller) mounted on an arm rotatable between operative and inoperative positions such that in the former it presses against co-operating means disposed near the entrance to the container to exert pressure on the two sheets as they are withdrawn in superposed relation between the pressure device and said co-operating means. In one embodiment, a tank 10 (Fig. 1) contains processing liquid 16 and a pressure roller 20 is mounted on arms 36 and is moved between an inoperative position (Fig. 1) and an operative position (Fig. 2), by depressing the handle 42. A squeegee is mounted frictionally on the bearings of roller 20. In operation the exposed sensitized sheet 11 is inserted into the tank 10, (Fig. 1) and an image-receiving sheet 13 is inserted into tray 12 above the tank. Stops 23 and 25 are operable to allow sheets of two different lengths to be used. After development the handle 42 is depressed and roller 20 presses the two sheets together against plate 18 (Fig. 2). The ends of the sheets are then grasped and pulled together under the roller, the squeegee 19 removing excess solution from sheet 11. A thin layer of the unhardened gelatin on sheet 11 is thus transferred to sheet 13. Further layers of unhardened gelatin may be transferred to sheet supports by repeating the process until the gelatin is exhausted. In the embodiment shown in Fig. 8 the sensitized sheet 11 is developed in tank 62 and the receiving sheet is inserted between roller 60 and guide 66 while they are in the inoperative position shown by dashed lines. After development a layer of unhardened gelatin is transferred by bringing roller 60 to bear on roller 59, and pulling the sheets together through the rollers. Squeegee 64 acts against roller 65 to remove excess solution as before.
