摘要： A method for forming a spacer of an optical fiber cable includes the steps of providing a tension member and covering it with a spacer body of crystalline thermoplastic resin, the spacer body being formed on its outer periphery with a plurality of grooves each for supporting an optical fiber therein. An apparent diameter d0 of the tension member and a target diameter d3 of the spacer body measured at bottoms of the grooves are so determined as to satisfy an expression 0.5

摘要： A thrust bearing for a turbocharger of an internal-combustion engine is made of a copper alloy including a brass matrix and a needle-like Mn—Si-based compound dispersed in the brass matrix. Not less than 50% of the needle-like Mn—Si-based compound dispersed in a region from a surface of a sliding portion of the thrust bearing to a depth of 50 μm have a major axis extending from the inside of the sliding portion to the surface. The major axis makes an angle of 30° to 150° with the surface of the sliding portion when observed in a sectional view perpendicular to the surface of the sliding portion.

摘要： A copper-based sliding material including a steel back metal layer and a Cu alloy layer is provided. The Cu alloy layer contains 0.5 to 15 mass % of Sn, 0.2 to 5 mass % of inorganic compound particles and the balance being Cu and unavoidable impurities. The inorganic compound particles are dispersed in a Cu alloy matrix and have an average size of 1 to 10 μm. A ratio of a true density of the Cu alloy matrix in relation to that of the inorganic compound particles is 0.6 to 1.4 and a ratio of a thermal expansion coefficient of the Cu alloy matrix in relation to that of the inorganic compound particles is 1.5 to 3.0. An average distance between the inorganic compound particles dispersed in the Cu alloy matrix is 5 to 50 μm.

摘要： Disclosed is a sliding bearing used in turbochargers of internal combustion engines. It is formed with a copper alloy containing, by mass %, 25 to 45% Zn, 0.3 to 2.0% Si, 1.5 to 6.0% Mn, and the balance being Cu and unavoidable impurities. The sliding bearing has a cylindrical shape for supporting a rotating shaft. Crystallized Mn—Si compounds are dispersed in a matrix of the copper alloy, the compounds extending in an axial direction of the rotating shaft on a sliding surface of the sliding bearing. The crystallized Mn—Si compounds have an average inter-grain distance of 20 to 80 μm. The matrix may contain precipitated Mn—Si compounds as well as the crystallized Mn—Si compounds.
