Filed: 1963-08-28
Abstract: 1,048,424. Semi-conductor devices. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Aug. 28, 1963, No. 34056/63. Addition to 1,007,936. Heading H1K. In a planar semi-conductor device comprising a zone of one conductivity type formed as an inclusion in the surface of a layer of uniform resistivity material of the opposite conductivity type the layer and its junction with the inclusion are insulation covered. A deposited metal electrode making contact with the inclusion extends across the junction over the insulation, which is made thinner where the junction surfaces than it is beyond this point. The thickness at the junction is chosen to provide optimum protection while the thickening elsewhere enables the parasitic capacitance between the electrode and the layer to be reduced. Capacitance may be further reduced by providing outside the junction beneath the insulation a zone making a PN junction with the layer, as in Fig. 2 (not shown). The transistor shown in Fig. 1 is produced in multiple by first providing an N-type layer on a lower resistivity N-type silicon wafer with an oxide layer 10, 2-10 Á thick, and forming windows therein by photolithographic techniques. The surface of the layer is again oxidized to a thickness of 0À5-1 Á within the windows. Apertures are then formed within the windows and boron diffused through them to form P-type base zones 2 in the layer. By a similar technique of phosphorus diffusion N-type emitter zones 3 are formed. Layers 4 and 5 are then partially exposed by removal of oxide and extended base and emitter contacts 8, 9 provided by vapour deposition of aluminium. The wafer is then subdivided and individual transistors mounted on collector headers. If germanium or gallium arsenide is used instead of silicon the oxide layers are provided by vapour deposition.

In a spring suspension system for vehicles wherein air cushions are used as suspension means and transmission of load to the air cushions is by a liquid under pressure, the liquid is subjected to the action of an air cushion and a solid resilient body, for example, a helical spring, for the purpose of superimposing, during the entire duration of shock or jolt independently of their intensity, a substantially linear characteristic of the spring action of a solid resilient body on the predominantly hyperbolic air spring characteristic. In the arrangement according to Fig. 1, a road wheel 2 is supported on a frame 1 by an air cushion 9 through the medium of a pressure liquid system including a piston 3 movable in a cylinder 4. The pressure liquid is also in communication with a vessel 7 and acts therein upon a leaf spring assembly 11 through a piston disc 10. A pump 16 is connected to the pressure liquid line 5 through a piston valve 15 mechanically connected to the wheel 2 and adapted to regulate the flow of liquid to or from the pressure liquid line 5. In the arrangement according to Fig. 2 (not shown), the connections between the pump and the pressure liquid line includes valves by which the automatic control of liquid to or from the pressure line may be cut out and the supply of liquid adjusted manually. A compressor is connected to the air cushion 9 and may be controlled automatically through valve means mechanically connected to the wheel 2 or optionally controlled, through change-over valves, to adjust the air pressure in the cushion 9. In a further arrangement, Fig. 3 (not shown) the piston valve 15, Fig. 1, is adjusted in dependence upon movement of the pressure liquid in line 5, the valve 15 being connected to a piston in a cylinder forming part of the pressure liquid line 5.

Abstract: 981,991. Mobile platform elevators. COTTERELL & PITHER Ltd. Nov. 27, 1963 [Sept. 6, 1962], No. 34235/62. Heading B8H. The platform 1 of a mobile elevator is connected to a base 2 by links 3, pivoted to the platform at 7 and slidably connected to the base at 8, and links 4, pivoted to the base at 7a and slidably connected to the platform at 8a and is raised by a pair of hydraulic rams 13, 14 each pivoted at 15 to the base and at 23 to a bell crank which is pivoted at 22 to a projection 19 on a tube 20 extending between, and secured to, the links 4. When the platform is in the lowered full-line position, Fig. 3, initial extension of the rams rotates the bell crank 17 about the pivot point 22 until a roller 24 on the bell crank engages a spring steel strip 25 on the base. Further extension of the rams causes further rotation of the bell crank 17 about the pivot point 22 thereby raising the pivot point 22 and raising the linkage 3, 4 by means of the projection 19 and tube 20. The rotation of the bell crank 17 continues until the pivot point 15, 22, 23 are in line and thereafter the roller 24 is lifted from the strip 25 and the raising of the platform 1 continues to the dashed-line position, Fig. 3. A stop 27 may be provided on the projection 19 to limit the rotation of the bell crank 17 so that the rams begin to lift the platform 1 by acting directly on the projection 19 before the pivot points 15, 22, 23 are aligned. The flexible strip 25 is normally clear of the ground but deflects under the load from the roller 24 until it contacts the ground to prevent the elevator from movement over the ground during the first stage of lifting the platform. In a modification, the bell crank 17 is replaced by a bell crank having three rollers, Fig. 4 (not shown), adapted to engage the strip 25 in turn during the first stage of lifting the platform. In a further modification (not shown) a plurality of bell cranks, each coming into operation in turn, is provided. It is stated in the Provisional Specification that the roller or rollers on the bell crank may be replaced by a slide block or blocks which slide over the strip 25.
