Filed: 1991-06-13
Abstract: ABSTRACT OF THE DISCLOSURE              A permeable base transistor or an electronic component layer having a permeable base transistor is formed by providing a stack on a semiconductive substrate of insulating, conductive and insulating layers one on another and then structuring that stack to form a grating between the bars of which semiconductive material is deposited by selective epitaxial growth techniques preferably with alternating doping.  With this construction, because of the presence of the insulating layers above and below the conductive gate fingers, the space charge zones are reduced in volume to reduce the capacitance of the permeable base transistor and permit higher transit frequencies.

Abstract: A RAIL ANCHOR WRENCH               Abstract of the Disclosure A wrench for applying rail anchors to the flange of a rail of a railroad track.  The wrench includes an elongated handle and a shoe.  The shoe is connected to the handle by 21 pair of links which are pivotally connected to the shoe and the handle.  The shoe has a nose, a tine, a heel and a jaw opening.         The jaw opening is defined between the nose and the tine and receives the hook end of a rail anchor when the hook end is placed over the flange of a rail prior to installation.  The nose of the shoe rests on the flange face of the rail in contact with the hook end of the anchor when the wrench is in its anchor installing position.  The first link of the pair of links is pivotally connected at one end to the handle and at its opposite end to the nose of the shoe.  The first link engages the head of the rail to fix in position its pivotal connection with the handle.  The second link connects the handle and the heel of the shoe.  As the handle is rotated about its pivotal connection with the first link, the second link forces the shoe to rotate about its pivotal connection to the first link.  Rotation of the shoe forces the anchor into engagement with the rail flange until the anchor latch is seated.

Abstract: A process for the clean-up of wet tailings ponds produced in the operation of an oil sands extraction process includes the steps of removing matter from all layers of a pond and vacuum filtering the combined matter to obtain clarified water, bitumen and dry tailings. With this process, tailings ponds may be completely removed and the water contained therein recycled to the extraction process.  The uncovered area may be mined and the dry tailings may be used to reclaim mined-out areas.  Residual bitumen recovered from the pond material contributes to a reduction of the clean-up costs.  Environmental damage is minimized by complete removal of the pond.

Title: Process and device for pulverization and separation
Inventor: NISHIBORI SADAO
IPC: B02C21/00
Filed: 1992-10-22
Abstract: The materials to be treated, for instance, molded resin articles with resin films coated thereon are treated by relatively simple means to separate and remove the resin film coatings from the surfaces thereof, and are further treated to recover them as a raw-form of resin material or a resin material regulated such that its particle diameter lies within a given particle diameter range, or the materials to be treated, for instance, powder materials are pulverized and granulated. A molded resin article is crushed to small pieces, to which compression impacts based on fine vibrations are in turn applied for squeezing, and resin film coatings separated off the small pieces are removed. The thus treated small pieces are further re-pulverized, and frictional crushing impacts are applied to the thus pulverized pieces as well for polishing and size-regulation. Alternatively, directional fine vibrations are applied to one of the inner and outer compression impact surfaces of inner and outer compression impact members that are located in opposition to each other with a given gap between them to pulverize and squeeze the material to be treated that is fed between the compression impact surfaces, thereby separating surface thin films therefrom for granulation.

Title: Luminal stent, holding structure therefor and device for attaching luminal stent
Inventor: IGAKI KEIJI
IPC: A61M29/02
Filed: 1991-11-20
Abstract: A luminal stent is a tubular body formed by knitting a yarn of a bioresorbable polymer fiber, such as fiber of polylactic acid, polyglycol acid or a polylactic acid - polyglycol acid copolymer. When introduced into and attached to the inside of the vessel by a catheter fitted with a balloon, the tubular member may retain its shape for several weeks to several months after attachment and subsequently disappears by being absorbed into the living tissue. In this manner, the luminal stent is not left as a foreign matter semi-permanently in the living body without producing inflammation or hypertrophy in the vessel.      There is also provided a method for attaching the luminal stent in the vessel.

Title: Encoder, data detecting semiconductor integrated circuit applicable to the same and dynamic sense amplifier
IPC: G06F17/30
Filed: 1993-01-08
Abstract: A encoder has a prefetch circuit or a flag data sense circuit built into the priority encoder provided for a CAM block.  While a hit signal in the first priority subblock is being encoded, a hit signal in the second priority subblock can be stored in the prefetch circuit.  Therefore, the encoding operation is performed without subblock-to-subblock switch time and this makes the encoder best suitable for a large capacity CAM which is required to operate at high speed.  Moreover, a semiconductor integrated circuit of the present invention detects the differential current between the current flowing through one signal line and the reference current flowing through the other signal line.  Moreover, it can operate as the number detection circuit to detect the number of hit signal in the subblock, and it can operate as the timing control circuit to previously notify the encode termination of the hit signal in the subblock of the encoder described above.  Therefore, this semiconductor integrated circuit can allow the encoder to encode very efficiently at high speed.  Moreover, a dynamic sense amplifier is able to operate with a great operating margin.

Title: Vehicle vibration simulator and method for programming and using same
Inventor: DEGROAT DOUGLAS E
IPC: G09B9/052
Filed: 1993-03-01
Abstract: "VEHICLE VIBRATION SIMULATOR AND METHOD FOR PROGRAMMING AND USING SAME"                         ABSTRACT A method of programming a vehicle simulator to provide an operator of the simulator with exertional and vibrational responses substantially the same as the driver of an actual vehicle would experience when driving the vehicle has been provided.  The simulator comprises a frame supporting a vehicle seat from which the operator operates a gear shift, an accelerator pedal, brake pedal, clutch pedal and steering wheel. Inflatable pods are provided under each corner of the simulator to simulate road conditions and turning of the vehicle by selectively deflating them.  Each of these controls selectively provides one or more signals to a programmed logic controller (PLC) which provides suitable signals to devices for controlling movement of the simulator to closely simulate movement of a vehicle under similar circumstances.  The simulator can be used to determine the tolerance level of a person to the exertional and vibrational levels of a simulated vehicle over a given time period. Thus, the ability of the person to perform the tasks required under normal conditions can be evaluated to determine if the person is employable as a driver of the actual vehicle, or has been rehabilitated following injury to the point of returning to their former job as a driver of the actual vehicle.
