摘要： Plastic composite gears and bearings with excellent friction and wear properties and further, plastic composite molded parts with excellent dimensional accuracy, can be presented at a low cost without adding large quantities of solid lubricant and glass fibers, etc., by adding a crystalline nucleus to crystalline polymers, such as polyacetal, polyamide, polyphenylene sulfide, etc., molding while applying vibrational energy, heat-treating the molded part after molding at a temperature that is the glass transition point of the crystalline polymer or higher and the melting point of the crystalline polymer or lower, heat treating the molded part after molding in the presence of a natural mineral, or by irradiating the molded part after molding with far infrared rays or infrared rays in order to reduce spherulite size of the crystalline polymer in the molded part and increase the degree of polymerization and thereby control crystal morphology and reduce the coefficient of friction and specific wear rate, and the molded parts have excellent recyclability.

摘要： A method for testing leakage of a pipe passage employs a flow rate of gas used in testing supplied to the inside of a pipe passage undergoing testing hermetically sealed on one side while detecting flow rate with a flow measuring device and pressure with a pressure detector, and detecting temperature of the gas used, and inputting the detected values of pressure, flow rate and temperature into a computation treatment apparatus, and internal capacity VL of the pipe passage is computed as VL=(supplied flow rate Q×pressure applied time Δt)/(pressure rise value ΔP2), and next, the volume QL leaked from the pipe passage is computed as QL=(pressure drop value ΔP2′×internal capacity VL)/(pressure drop time Δt′).
