Filed: 1973-10-16
Abstract: 1446236 Semi-conductor devices HITACHI Ltd 16 Oct 1973 [18 Oct 1972] 48202/73 Heading H1K A charge transfer semi-conductor device (Fig. 5c) comprises a plurality of buried charge transfer passages 54-57 of opposite conductivity type to the semi-conductor substrate 51 formed within it and located intermediate the gate electrodes 58. The passages may be formed by the implantation of ions of the opposite conductivity type to the substrate. The arrangement enables inter-electrode spacing to be increased, the charges between depletion regions below electrodes flowing through the passages, eliminating the surface trapping of prior art devices. To prevent coupling of depletion regions, highly doped surface adjacent regions, of the same conductivity type as the substrate, may be located between the electrodes, e.g. by phosphorous ion implantation. The device may be formed with aluminium electrodes 58 etched from a layer deposited on an oxide layer 52. Alternatively the electrodes may be of boron doped polycrystalline silicon and covered with a layer of vapour deposited oxide. In either case the electrodes can be used for masking the ion implantation to give a self aligned structure.

For example, if contact S 12  is closed and switch S 11  is placed in its second position, contact 11 is connected to the moving contact of the switch so that whenever key 1 in keyboard a is played the resulting signal from bus-bar 8 is passed to amplifier V of keyboard a and amplifier V<SP>1</SP> of keyboard b. The signal passed to amplifier V can be controlled in volume by device 18, further devices 18<SP>1</SP> and 18<SP>11</SP> being of similar construction. By placing switch S 11  in its third position keyboard a is coupled to both amplifiers V<SP>1</SP> and V<SP>11</SP> and by placing the switch in its fourth position keyboard a is coupled to amplifier V<SP>11</SP> of keyboard c. The amplifiers have variable output characteristics controlled by stops to provide a variety of effects. If switches S 12 , S 12 <SP>1</SP> are opened and S 11 , S 11 <SP>1</SP> placed in their second positions, keyboard a plays through amplifier V<SP>1</SP> and keyboard b plays through amplifier V i.e. the amplifier and stops of keyboards a, b have been interchanged. In a further example, keyboard c may be arranged to play through both stop groups of keyboards a and c simultaneously. Various further combinations of the keyboards and amplifiers are possible by appropriate use of the switches.

Abstract: 1360684 Automatic control CINCINNATI MILACRON Inc 21 Oct 1971 [22 Oct 1970] 48878/71 Heading G3R [Also in Division B5] In an injection moulding machine, material is plasticized using friction by a rotatable and axially movable screw in a barrel, the rotational speed of the screw being automatically controlled to provide a desired shot size of plasticized material in a desired time. From values of the desired shot size, the desired plasticizing time and an estimated back pressure, applied hydraulically to a piston 22 on one end of screw 20, a digital computer in controller 32 calculates a trial rotational screw speed. The screw is maintained at this speed by a hydraulic or electric motor 26, and material e.g. polyethylene, polystyrene, polypropylene or ABS, is fed into gravity hopper 19, is plasticized and builds up at one end 17 of barrel 16, forcing the screw backwards away from this end, the back pressure on the piston  being controlled by valve 37 to maintain the temperature of the material, as sensed by transducer 33, at a predetermined value. When the screw has moved a distance Xs, equal to the desired shot size, a signal from a counter, fed from screw position transducer 30 e. g. a shaft encoder or a resolver, stops the motor 26, and pressure is applied to cylinder 23, from pump 36, to inject the plasticized material into a cavity 13 of a mould 11, 12. In controller 32 see also Fig.3 (not shown), the average of the actual time of actuation of motor 26 and the desired plasticizing time, is combined with the actual back pressure measured by transducer 35, to calculate a new screw rotational speed for the next run and this is repeated until the time error is eliminated. Band heaters 31 on the barrel may be used to maintain it at a uniform high temperature and prevent heat losses. A valve (not shown) may be interposed between the barrel 16 and the mould.
