    摘要: An improved investment casting process for producing dental restorations, particularly a dental crown, comprising the steps of fixing a wax pattern onto a truncated cone in a metallic ring having a lining of a cushioning material, pouring an investment material into the space around the wax pattern in the metallic ring, drying the resultant product, melting out the invested wax pattern, curing the resultant product at a temperature of 700.degree. to 950.degree. C for 20 to 150 minutes to give a mold, fixing the mold thus obtained to a centrifugal casting machine and casting a molten chromium-cobalt and/or nickel alloy in the mold maintained at a temperature of 100.degree. to 500.degree. C.

    摘要: A linear bearing structure comprises a bearing bush, a plurality of annular ball retainers each holding a plurality of bearing balls, circumferentially and a pair of annular endpieces respectively removably secured to ends of the bush to confine the ball retainers therein. The bearing bush comprises an outer metal cylinder and an inner cylindrical lining layer formed by a bearing material having a small coefficient of friction and a small coefficient of wear and is provided with a slit which has a predetermined width and extends along the axis of the bush over the entire length thereof so that the bush can be circumferentially elastically compressed by a magnitude corresponding to the width of the slit. Each of the endpieces has, at the inner side thereof, an annular groove having a diameter smaller than that of the bush so that by compressing the bush into the annular grooves of the endpieces at the ends of the bush, the bush and the endpieces can be elastically fitted together.

    摘要: An automatically tiltable small roller structure, which comprises a shaft, a small roller including an elastic rubber cylinder and a sleeve, and a plurality of bearing balls. The sleeve is integral with the inner periphery of the elastic rubber cylinder, and mainly composed of polytetrafluoroethylene (fluoroplastics). The shaft is fitted in the roller structure. The bearing balls are fitted in a circumferential or annular groove formed on the shaft, and are provided such that they are in rolling contact with the inner periphery of the roller and the outer periphery of the shaft in the groove. The groove is provided at a middle point between the opposite ends of the roller. The depth of the groove is set such that the bearing balls project slightly from the groove, so that a slight gap is formed between the inner periphery of the roller and the outer periphery of the shaft. The axes of the roller and shaft are thus slightly tiltable in relation to each other.

    摘要: A throttle valve assembly for displacing the plungers of at least two contiguous throttle valves in correspondence with the degree of throttle opening of an engine includes a first cam rotatably mounted on a stationary bracket fixed to the throttle valve bodies and having a cam face for displacing the plunger of the first throttle valve and an axially extending boss, a second cam rotatably mounted on the bracket and having a cam face for displacing the plunger of the second throttle valve and an axially extending boss, the first and second cams being coupled via coupling means formed on the opposing bosses, and a cable operatively associated with the engine torque demand for rotating the cams. The cam faces of the cams are formed to have a shape capable of providing the desired throttle pressure characteristic, the shapes of the cam faces differing from each other in order to obtain the optimum speed-change performance.

    摘要: In a hydromechanical transmission, low and high speed drive power trains are selectively completed in response to variation of the speed ratio between an input shaft and an output shaft. The transmission comprises a speed ratio detecting valve for detecting lower and higher limits of a predetermined speed ratio and a clutch control valve for conducting the switchover between the low and high speed drive power trains with a predetermined time lag after the actual speed ratio reaches a range defined by the lower and higher limits of the predetermined speed ratio.
