Patent EP-0293588-A2 (EP)
Inventor: LESK ISRAEL ARNOLD
IPC: H01L27/06
Filed: 1988-04-21
Abstract: The present invention describes a method of producing MOS, Bipolar, or BiMOS pedestal transistors wherein the source, drain, and gate metals (57, 64) are in place prior to the source/drain diffusion (62) in a MOS transistor; and the emitter and base metals (57, 64) are in place before junction formation on the bipolar transistors. This is accomplished in MOS devices by a first blanket implantation of impurities into a first polysilicon layer (56) during processing and a second blanket implantation into a second polysilicon layer (63) subsequent to deposition of the silicide layers (57, 64). This is accomplished in bipolar devices by the above, or by blanket implantations subsequent to the deposition of the silicide layers (57, 64).

Abstract: A vacuum toilet system comprises a waste-receiving bowl (2) having an outlet (4), a sewer pipe (7) that can be placed at a pressure that is lower than that in the interior of the waste-receiving bowl, and a discharge valve (6) connected between the sewer pipe and the outlet for controlling passage of material from the waste-receiving bowl to the sewer pipe. The discharge valve (6) comprises a closure member movable by a drive mechanism (36) relative to a valve housing between an open position and a closed position. A sensing device (60) provides a control signal in the event that the drive mechanism is not able to cause the closure member to attain its closed position. A controller (50) is connected to the drive mechanism and responds to a user stimulus (via 58) to move the closure member from its closed position to its open position and subsequently from its open position towards its closed position. The controller responds to a control signal provided by the sensing device by causing the drive mechanism to move the closure member towards its open position and subsequently towards its closed position.

Abstract: An apparatus and method for measuring a uniform volume and weight of food material, and continuously delivering it, is provided. The apparatus (1) comprises screws (5) disposed at the bottom of a hopper (3) and a delivering means (7) having a rotating cylinder (27) and vanes (29) freely slidable in respective pairs of slots (31) formed in the periphery of the cylinder. The delivering means is disposed in a housing (9) and both ends of the vanes slidably contact the inner surface (21) of the side wall of the housing to form compartments (39) between each adjacent pair of vanes. In the apparatus, the material is fed by screws (5) and introduced into the compartment for measuring. Since the rotational speeds of the screw and cylinder are respectively controlled to introduce a sufficient amount of the material into the compartment, the density of the material in the compartment becomes uniform. The material is then continuously discharged from the apparatus.

Abstract: A high resolution image is decomposed into a low resolution replica and into corresponding supplemental information for facsimile transmission to a remote location. The low resolution replica is generated by replacing a super pixel (picture element) including a plurality of high resolution image pixels with a single low resolution pixel and corresponding supplemental information, if any is required. The pixels of the low resolution replica are chosen such that all supplemental information required to convert the low resolution replica back to the original high resolution image is located at the "edges" of the low resolution replica. Thus, if a low resolution pixel is at an edge in the low resolution replica, supplemental information is generated in accordance with prescribed criteria. In a remote receiver, the decomposition is reversed and the original high resolution image is recomposed by substituting the transmitted supplemental information, if any, for the corresponding low resolution pixels located at the edges of the low resolution replica.

Abstract: A method and apparatus for producing foam elastomer tires for various uses including bicycle and wheel chair tires with a minimum amount of wasted material. The method involves spin casting the tires wherein a mold with suitably designed tapers on the exterior surface is placed between press plates with corresponding annular tapers which cause the mold to be accurately centered within the press plates when the press is closed. The preblended liquid foamable materials are either poured directly into the mold or onto a surface immediately adjacent to the mold gate. One or more tension members are located within the mold such that either the incoming stream of preblended liquid foamable materials wet the tension member(s), or the tension member(s) lie more or less in the path of the expanding foamable material as it fills and forces its way out of the mold, or (preferably) both. This ensures that the foaming material completely covers the tension member(s) so that the tension members are fully embedded and form an integral part of the resulting tire. This novel arrangement provides a method of producing consistent, high quality tires.
