Patent EP-0244963-A2 (EP)
Inventor: ONDRIS MIROSLAV
IPC: C25D9/08
Filed: 1987-04-09
Abstract: A method of electrodepositing a doped compound semiconductor film (43) including tellurium and a metal selected from Group IIB of the Period Table of Elements by adding an effective concentration of dopant ions to the electrolyte bath. Cadmium telluride, mercury cadmium telluride and zinc cadmium telluride may be doped with copper, silver and gold. The conductivity type of the electrodeposited doped layers may be changed by a heat treatment. Thin film photovoltaic cells incorporating the doped layer to form a heterojunction with semiconductor layer (42) of the opposite conductivity type show substantial improvements in open circuit voltage, fill factor and efficiency over similar devices employing undoped electrodeposited layers.

Title: Plug-in type pump assembly
Inventor: SAILER THOMAS
IPC: F04B23/00
Filed: 1987-06-05
Abstract: Pump assembly (1) includes a rotatable handle (35) with integral cams (39, 40) thereon to releasably retain the pump assembly (1) within a receiver (2). During assembly, the pump assembly (1) is initially inserted only part way into the receiver (2) to a first intermediate non-operating position and then rotated a part turn to cause the cams (39, 40) on the handle (35) to be engaged inside receiver lugs (41, 42) on the receiver housing (8) which retain the pump assembly (1) in a second intermediate non-­operating position for pump drainage. While in such second intermediate non-operating position, the handle (35) may be pivoted between closed and open positions to respectively push the pump assembly (1) further into the receiver (2) to an operating position and pull the pump assembly (1) back out to the second intermediate non-operating position. Seal means (21, 22, 24) between the pump assembly (1) and receiver (2) are respectively engaged and disengaged during camming movement of the pump assembly (1) between such operating and non-operating positions. Also, one or more valve means (15, 19) are respectively opened and closed during such camming movement of the pump assembly (1) between such operating and non-operating posi­tions. The handle (35) may be trapped in the closed position by an electrical connector (55) which is adapted to be connected to the outer end of the pump assembly (1) to provide power to operate the pump assembly (1). A cover plate (56) may be used to cover an access opening (4) to the pump assembly (1) when the pump assembly (1) is in the operating position within the receiver (2). The handle assembly (35) will permit attachment of the cover plate (56) to the access opening (4) only when the pump assembly (1) is in the operating position and the handle (35) is in the closed position.

Abstract: A method of generating a two-dimensional image representing a three-dimensional scene is described. The method comprises: a) storing a set of foreground pixel data and at least one set of background pixel data, each such set defining a colour and a depth for each pixel of the image; b) selectively modifying the stored foreground and background data in response to a series of input pixel data defining colour and depth for a series of pixels of the image; and c) forming output pixel data by combining the stored foreground and background colour for each pixel in proportions defined by a mixing value associated with that pixel. In one embodiment, step (b) comprises selectively modifying the stored data depending on the input depths so that: 
(i) if the input depth is greater than the stored foreground and background depths, the stored foreground and background pixel data are left unchanged, (ii) if the input depth lies between the stored foreground depth and the stored background depth, the input pixel data is stored in place of the background data for that pixel, and (iii) if the input depth is less than both the stored foreground and background depths, the stored current foreground data for that pixel are stored in place of the stored background data and the input data are stored in place of the current foreground data. An arrangement is described for performing the method. The arrangement may form part of an electronic graphics system.

Abstract: The disclosed light emitting semiconductor device has an n-type (or p-type) base region sandwiched by a p-type (or n-type) emitter region and a p-type (or n-type) collector region. An injecting voltage source is connected across the emitter region and base region so as to apply a constant voltage therebetween, while a control voltage source is connected across the emitter region and the collector region so as to selectively apply a reverse bias to a base-collector junction for controlling recombination of carriers injected to the base region. The control voltage source produces such non-emitting period voltage and emitting period voltage that carriers injected during the non-emitting period voltage are captured in the base region while the carriers thus captured are allowed to recombine during the emitting period voltage.
