Abstract: 1372779 Integrated circuit manufacture INTERNATIONAL BUSINESS MACHINES CORP 5 Sept 1972 [22 Nov 1971] 41084/72 Heading H1K When an epitaxial layer is grown over a semiconductor substrate having diffused inclusions in its surface impurity may evaporate into the atmosphere from the inclusions and diffuse back into adjacent areas of the substrate to cause undesirable short circuits between adjacent inclusions. This is compensated for by diffusing impurity determinative of the conductivity type opposite to that of the inclusions into their surfaces prior to the epitaxial deposition. In the embodiment the inclusions are N+ subcollector regions formed by diffusing arsenic or phosphorus into a silicon wafer via oxide masking. Boron or gallium is then diffused as compensating impurity via the same mask to provide shallow P+ regions. An N-type layer is epitaxially deposited after removal of the mask and P-type isolating regions formed in it by masked acceptor diffusion. Subsequent masked acceptor and donor diffusions provide base and emitter regions and contact is made thereto and to the collector region via holes in oxide masking. The shallow P+ regions are so doped that by the time the above processes are complete they will have been converted to N-type. If desired the wafer may have a plurality of integrated circuits including diodes and resistors formed on it. These may subsequently be diced from the wafer.

Title: Improvements in or relating to fuel injection apparatus
IPC: F02M59/20
Filed: 1962-11-01
Abstract: 1,080,311. Fuel injection pumps. W. FRIEDLANDER. Jan. 31, 1964 [Nov. 1, 1962], No.41375/62. Heading F1A. A fuel injection pump comprises a housing 10, a pumping chamber 12 which receives a governed amount of low pressure fuel, a first reciprocating member 39a which pumps the fuel to an injection nozzle 20, and a second reciprocating member 39b separated from the member 39a by hydralic fluid such that reciprocation of the second member causes reciprocation of the first member. A low pressure fuel feeding device 21 and the injection pumps are actuated from a common cam-shaft 42. A plunger 46 of the device 21 supplies fuel to the injector pumps through a conduit 22 and a collar 47 on the plunger supplies fuel to a chamber 29, in which is located a governor valve 28. As the fuel pressure builds up, the valve 28 moves until a reduced diameter portion 30 interconnects conduits 27, 31, thereby opening a by-pass circuit. The angular setting of a peripheral cut-away portion 37 on the valve 28 relative to a return conduit 48 determines the rate at which fuel flows to the conduit. The cut away 37 varies in radial depth around the valve circumference and its setting is adjusted by a lever 38. A gear pump 81 supplies hydraulic fluid to a space 61 between the members 39a, 39b of the injection pump plunger 11. The member 39b is actuated by a cam 19 and injection is terminated when the member 39a uncovers a by-pass passage 86. A relief valve 85 maintains a constant pressure in the hydraulic circuit thereby keeping the member 39b in contact with the cam 19 and hence maintaining the injection timing constant. Alternatively the relief valve 85 may be replaced by a restriction (89) so that the pressure is proportional to engine speed and by having to overcome a spring (98a) acting on the member (39b) injection timing is progressively advanced as the engine speed increases, Fig. 3 (not shown). In a preferred embodiment of the pump 9, the member (39b) is replaced by a cap (17a) which slides over the pump barrel (10) and is directly acted upon by the cam, Figs. 4, 5 (not shown).

Abstract: 994,762. Resilient mounting units. AEROFLEX LABORATORIES Inc. Oct. 21, 1963 [Oct. 25, 1962], No. 41486/63. Heading F2S. A resilient supporting unit comprises a ring of circumferentially-spaced L-shaped stranded wire cable lengths 21a which are connected between the flange 17a of a cup-shaped member 15a having a central hub 16a and a coaxial annular member 19a and which pass through a floating ring 20a each cable length 21a including portions which extend radially and axially of the axis of the unit when the latter is not stressed by a load. Fig. 1 shows two identical opposed units the members 15a, 15b, with their hubs 16a, 16b in abutment, being connected by a bolt 22 to a strut 13 and the members 19a, 19b, spaced slightly in the axial direction, being secured to a bracket 10a. During fabrication of the unit the cable lengths are cast into the ring 20a and the annular member 19a and also into a ring 18a which is screwed on to the flange 17a of the cup-shaped member 15a. In a modification a continuous length of stranded wire cable is looped through holes in the cupshaped and annular members 17a, 19a and reeved through the ring 20a. To provide the desired spring rate the ring 20a may be segmented or even omitted in which case the L- shaped cable lengths may be prestressed during formation.

Filed: 1963-10-24
Abstract: 1,035,049. Respiratory appliances. C. G. D. ENGSTROM and P. HERZOG. Oct. 24, 1963 [Oct. 25, 1962], No. 42049/63. Heading A5T. A forced breathing apparatus, for artificial respiration, has an atomizer for medicaments &c. comprising a supersonic vibrator and liquid supply means, connected into the high pressure branch of the system. In the apparatus described a piston 2, reciprocated in a cylinder 1, provides the necessary pressure changes and, in moving towards the right compresses a bag 7 to force air through pipe 11, carbon dioxide absorber 15 and atomizer 61 to the lungs 20. On the reverse stroke of the piston the bag 7 is distended and withdraws air from the lungs through an air drier 22, non-return valve 26, pipes 37, 36 and valve 31. A bladder 38 serves as a form of accumulator and any additional air required is drawn in through a valve 43. If the system is to be operated on open circuit, the plug valve 40 is turned to close pipe 37 and to connect chamber 24 with a venturi arrangement 50 in which the air displaced by the piston on the return stroke is employed to assist in the withdrawal of air from the lungs. In the atomizer, liquid from a supply flask 80 drips from a tube 88 through a funnel 91 on to a plate 73 vibrated supersonically by a piezo-electric device 72. This causes it to be broken up into a fine mist which is carried away by the air entering at 69 and passing to the lungs at 70. A baffle 95 catches any relatively large droplets, which may be splashed up, and directs them back on to the vibrating plate 73. In two modified forms of the atomizer the supply of liquid is held in a container within the walls of the atomizer and in one of these the container is removable for convenience in refilling. A further type of atomizer uses a concave vibrating plate placed in the based of the chamber so that violent motion caused at its focus are located at the surface of liquid placed in the container and air flowing over the surface carries away the resulting mist. In each case suitable means prevents the liquid being forced back by the gas pressure.
