摘要： A ball bearing for supporting a spindle rotating at high speed is provided with at least one member of an inner race and a shaft having an inner raceway in an outer peripheral surface thereof, an outer race having an outer raceway in an inner peripheral surface thereof, and a plurality of balls having 3 mm or less in diameter which are rollingly provided between the inner raceway and the outer raceway, the balls being arranged along a pitch circle 11 mm or less in diameter. A bearing steel or stainless steel which is used to form the member having the raceway is reduced to 6% by volume or less in the amount of retained austenite, so that the raceways are improved in impression resistance. This eliminates the difficulty that the impression of the raceway lowers the acoustic characteristic.

摘要： A rolling part steel with which the strength of a rolling part of a cold-worked bearing is improved compared with that of a conventional turned part by controlling the length and number of sulfide inclusions in the steel to an optimal range, when a rolling part steel is prepared so that the maximum length of sulfide inclusions in the steel is 100 .mu.m or less and that a number of sulfide inclusions whose lengths exceed 40 .mu.m is 50 or less per unit area (160 mm.sup.2) , the roughness of its bore surface is improved to have a greater strength. As a result, for example, a thus formed raceway ring has a longer life against fatigue-induced cracks than a turned raceway ring.

摘要： In a corrective tempering method and apparatus for a rolling element in which the thermal deformation of the rolling element is corrected within an extremely short time by utilizing plasticity exhibited during a metallic structure transforming process brought about by low-temperature tempering of the rolling element made of steel, the hardened rolling element is heated and pressured to a maximum temperature within a range of from 250 to 500° C. by a heating device while set in correcting molds to correct the deformation of the rolling element at a degree of working within a range not exceeding an elastic deformation range of the rolling element at a room temperature. The rolling element can be heated also by an induction heating device in addition to a conduction heating device. A product whose inner/outer diameter correcting degree of deformation is 60% or more, dimension standardizing rate is 30% or more, surface roughness is less than Ra 0.2 &mgr;m, and surface hardness is HRC 56 or more can be obtained for a correction time within 6 minutes and an induction heating time within 30 seconds.

摘要： Novel regenerated cellulose fiber dyeable with disperse dye is disclosed. In this regenerated cellulose fiber, 10 to 40 weight % of polyester fine particles or styrene-acrylic polymer fine particles having an average particle size of 0.05 to 5 .mu.m are compounded. Products wherein the regenerated cellulose fiber and polyester fiber are used in combination can give dyed products excellent in homochromatic properties, and since both fibers can be dyed at the same time, the dyeing efficiency is remarkably improved.
