IPC: H01L27/148
Filed: 1981-09-21
Abstract: A semiconductor imager comprises a first and a second region (41, 42) which have a conductivity type opposite to a substrate (21) and are reversedly biassed relative to the substrate beneath photosensitive regions (22) of each row and a reading device (26, 33) for the row, respectively, to be completely and not to be completely depleted, respectively. The imager may or may not comprise such a covering region (77) on each photosensitive region as may have the conductivity type of the first and the second regions and be not completely depleted. It is possible to provide a line sensor or a photodiode of a similar structure. Preferably, the first and the second regions have a common impurity concentration lower than the photosensitive regions and are thinner and thicker relative to each other. The covering region preferably has an impurity concentration of each channel stopper (23).

Abstract: A scroll type fluid displacement apparatus is disclosed. The apparatus includes a housing. A fixed scroll member fixedly disposed within the housing and comprises a first end plate means from which a first wrap means extends. An orbiting scroll member also comprises a second end plate means from which a second wrap means extends. Both wrap means interfit at an angular and radial offset to make a plurality of line contacts to define at least one pair of symmetrical sealed off fluid pockets. The first end plate means is formed with two holes which are placed at the symmetrical position. A valve means controls the passage of fluids through the holes. The valve means is controlled by the changes of the external environment. The capacity of compressor can thereby be easily changed in response to the changes in the external environment.

Abstract: Es werden ein Verfahren und eine Vorrichtung zur Steuerung der vom Abgassystem einer Brennkraftmaschine zur Saugseite rückgeführten Abgasmenge vorgeschlagen, bei der die angesaugte Luftmenge mit einem in Abhängigkeit von Last und Drehzahl gebildeten Sollwert verglichen wird und bei einer Abweichung, die größer ist als ein Minimalbetrag Steuerimpulse für zwei Magnetventile (16, 20) gebildet werden, die je nach Abweichungsrichtung alternativ angesteuert werden und Druck aus zwei Druckquellen unterschiedlichen Niveaus in den Arbeitsraum eines pneumatisch arbeitenden Stellgliedes eines Abgasrückführdosierungsventils leiten. Die Öffnungsdauer des jeweiligen Ventils ist dabei abhängig von der Größe der Sollwertabweichung und bleibt bis zur gegenteiligen Korrektur ganz geöffnet, wenn die Sollwertabweichung einen bestimmten Höchstbetrag überschreitet. Die im Bereich zwischen minimaler und maximaler Abweichung vom Sollwert gebildeten Steuerimpulse werden jeweils nach einer bestimmten Wartezeit (TW) an die Magnetventile weitergegeben, wobei die Wartezeit drehzahlabhängig gemacht werden kann.

Abstract: A rubber-modified thermoplastic resin is produced by graft-copolymerizing an aromatic alkenyl compound, an alkenyl cyanide and a methacrylic acid ester onto an ethylene-propylene rubber. The polymerization is carried out in two steps. In the first step, the aromatic alkenyl compound and the alkenyl cyanide (optionally with up to 20% by weight of at least one other copolymerizable monomer) are graft-copolymerized onto the rubber until the polymerization conversion has reached a value within the range from 30 to 70% by weight. In the second step, a methacrylic acid ester (optionally in admixture with up to 20% by weight of at least one copolymerizable monomer) is polymerized in the presence of the reaction mixture from the first reaction step, until polymerization is substantially complete. The resulting resin has excellent impact resistance and colourability and produces a moulded article having good appearance.

Abstract: The pattern of pressure variation in the breathing gas supply is detected by a pressure sensor 50 whose digitized output is fed to microprocessor 56. A reference pattern is stored in memory 54 and the actual pattern is monitored to detect departures from the reference pattern. Display 58 and alarm 60 are activated when comparison by the microprocessor shows a significant deviation from normal. Control panel 62 allows intervention when changes in the breathing pattern result from known external causes. 
     Conventional gas monitor 15 senses the partial pressure of a component of the breathing gas to measure its concentration (output signal 68) and also provides a time-varying pressure signal 66 which serves as a check on the pressure sensor 50.

Abstract: An apparatus for turning a steerable vehicle wheel includes a pump assembly which is connected with a reservoir through an inlet valve. Upon rotation of a steering wheel, the inlet valve is actuated to allow fluid to flow from the reservoir to the pump assembly at a rate which varies as a function in variations in the speed of rotation in the steering wheel or the torque applied to the steering wheel. The output from the pump assembly is conducted to a directional control valve which is actuated upon initial rotation of the steering wheel to direct fluid flow to the power steering motor to effect turning movement of the steerable vehicle wheel in a desired direction. The rate at which the power steering motor turns the steerable wheel is determined by the extent to which the inlet valve is opened and is independent of the directional control valve.

Abstract: A driver circuit for an electroluminescent matrix-type display includes a brightness control circuit (430) for essentially eliminating variations in luminescence (inverse shadowing) of display pixels (101) by controlling the time rate of change of the pixel drive voltage at and above the threshold voltage for light emission.

It includes a counter (435) for counting the number of pixels to be lit, a conversion circuit (440) for converting the count into an analog voltage (443) and a summation circuit (445) for adding the analog voltage (443) to a minimum row drive voltage (Rhv(min)). The brightness circuit (430) is reset for each new row to be driven to develop a new count of pixels to be lit from pixel selection pulses to a column driver circuit (420).
