The stacked rods may be bonded together by means of an epoxy adhesive and their ends may be rough ground and shot-blasted prior to the explosive bonding step. For the latter the metal capping may be tack-welded in position and a primer cord 44 used to ignite the explosive layer 42. The preliminary cutting step may provide complementary rods for upper and lower matching die sections (Fig. 4, hot shown) at least one of these being provided with an explosively bonded capping.

Abstract: 1302200 Converting reciprocal motion into rotary motion MONOMECH DEVELOPMENTS Ltd 27 Oct 1970 [30 Oct 1969] 53344/69 Heading F1A An hydraulically operated mechanism for producing rotary motion of a shaft 10 from reciprocation of two rams 12, comprises cranks 14, 24 connecting the piston rods 13 to the shaft 10. The mechanism is controlled by valves 20, 26, the valves 20 having spools 22 which reciprocate as the rams rock due to shaft rotation. Such reciprocation of spool 22 ensures supply of fluid to the rams 12 in a sequence which maintains smooth rotation of the shaft 10. As they reciprocate, they alternately connect opposite sides of their respective rams to high pressure and to exhaust. If the pressure in either cylinder exceeds a certain value the appropriate side of a double check valve 32 opens to supply fluid back to the source through a shuttle valve 30.

Title: Methods of manufacturing a semiconductor device

Filed: 1970-01-15
Abstract: 1332931 Semi-conductor devices MULLARD Ltd 4 Dec 1970 [15 Jan 1970] 1996/70 Heading H1K The emitter of a transistor is formed in a mesa and the base region is formed by implanting ions into the mesa and through adjacent parts of an insulating and passivating layer surrounding the mesa, the profile of the base-collector junction being such that its depth below the plane of the top of the mesa is no greater in that portion directly below the mesa than in the surrounding portions. A transistor is produced by growing an N type epitaxial layer 3 on an N+ type substrate 2, applying a masking layers of Si 3 N 4  and utilizing superimposed silicon oxide and photoresist layers to etch a rectangular ring-shaped window in the Si 3 N 4  layer. A groove is then etched in the exposed surface of the epitaxial layer to define a mesa portion and any remaining parts of the oxide layer are etched away. B ions are then implanted into the surface of the groove to form a heavily doped base contact region (16) the plane portions of the wafer being masked by the remaining parts (5, 18) of the Si 3 N 4  layer, Fig. 2 (not shown). A thick layer of SiO 2  is applied by pyrolytic deposition or by sputtering and selectively etched to leave only that portion 19 surrounding the outside of the groove, Fig. 3 (not shown). The exposed surface of the wafer in the groove is covered with a thin oxide layer 10 by heating in steam, Fig. 4 (not shown), and the portion (5) of the Si 3 N 4  layer on the top of the mesa is removed by etching, Fig. 5 (not shown). P is diffused-in from the gas plane to form an N + + type emitter region 8. The base region of the transistor is then formed by implanting B ions through the exposed emitter area and into the grooved area through the thin oxide layer 10, the thick oxide layer 19 acting as a mask, and the wafer is annealed Fig. 6 (not shown). The phosphorus glass layer formed during the emitter diffusion is removed by dipping in HF, base contact windows are etched using a photoresist mask, and a layer of Al is deposited and etched to form an emitter electrode 14 connected to a bonding pad and two base electrodes 15 which are connected together at one end and provided with a bonding pad. A plurality of such transistors may be provided in a single wafer which is then subdivided and the individual devices encapsulated. In alternative production methods the emitter region may be produced by local epitaxial deposition through a window in a mask, by doping the surface and then etching the surrounding groove, by ion implantation, or by "knock-on" implantation.
