摘要： A constant velocity universal joint comprising: an inner race having a plurality of inner grooves; an outer race having a plurality of outer grooves; a plurality of balls arranged individually in the plurality of inner grooves and in the plurality of outer grooves; and a retainer for retaining the plurality of balls. The center of curvature of the plurality of inner grooves and the center of curvature of the plurality of outer grooves are set on the both sides of a bisector. The plurality of inner grooves are formed helically in the inner race, and the plurality of outer grooves are formed helically in the outer race. The adjoining inner grooves are inclined in opposite directions, and the adjoining outer grooves are inclined in opposite directions.

摘要： A rotary coupling for torque transmission is arranged between two relatively rotatable shafts to transmit a rotational torque in response to a rotational speed difference therebetween. The device includes a housing connected to the first shaft for rotation therewith, a clutch means for transmitting rotational torque between two shafts, and a piston which thrusts the clutch means in the axial direction. The rotary coupling also includes a rotor received in a cylindrical space, in which a high viscous fluid is filled to be compulsorily moved by the rotor. Each side surface of the rotor is provided with plural depressions at regular interval in the circumferential direction. The depressions have inclining surfaces inclining in the rotational direction of the rotor. When a rotational speed difference occurs between the two shafts, wedge effects occur between the inclined surfaces and the housing and between the inclined surface and the piston so that a high pressure is generated in the space section quickly.

摘要： An admixture for cement compositions is prepared by calcining at 630.degree. to 870.degree. C. at least one substance selected from the group consisting of natural kaolin, halloysite and synthetic kaolin, effecting classification so that amorphous portions of alumina/silica having a mixing ratio of 0.5 to 1.3 form main components, with all particles having diameters up to 8 .mu.m and an average diameter of 0.5 to 2 .mu.m, and a specific gravity ranging from 2.45 to 2.55. This admixture is used to produce a cement composition such as mortar or concrete, which realizes excellent fluidity to promote workability, and a high strength structure.
