摘要： A rotating shaft 4 is attached to an inner race 1, and an outer race 2 is fixed to a housing 5 so that the bearing is operated by the rotation of the rotating shaft 4. In this case, the inner race 1 is made to be the race on the rotating side, and the outer race 2 is made to be the race on the non-rotating side. The raw material composing the inner race 1, outer race 2 and rollers 3 is manufactured from alloy steel containing 4.5 weight % or less of Ni, and 0.5 weight % or less of Cu, and the average value of the Cu equivalent of the rollers 3 and the inner race 1 is set at a value higher than the Cu equivalent of the outer race 2. Thus, even in humid environments where water infiltrates into the lubricant, it is possible to make the rolling bearing have the same durable life as with rolling bearings which are used in normal environments. Accordingly, it is possible to provide rolling bearings endowed with superior durable life from the electrochemical viewpoint even when water infiltrates into the bearing lubricant.

摘要： A bearing with dynamic pressure grooves includes an outer cylinder made of a metal and a resin sheet bonded to the inner peripheral surface of the outer cylinder. The resin sheet is made of a thermoplastic resin, for example, a polytetra fluoroethylene, as a main component mixed with a wear-resistant improving material, for example, graphite or the like. The resin sheet is formed with a pattern of dynamic pressure generating grooves formed in an inner surface by plastic work. The pattern of grooves is varied depending on the types of relative movement between the outer cylinder and a shaft body, i.e., whether an axial linear movement, a rotational movement, or a spiral movement.

摘要： A pulse code modulation terminal equipment, having a first hold circuit which continuously supplies a multiplexer unit with a seizure signal supplied from a seizure supervisory circuit during a predetermined time after a fault is detected. The first hold circuit prevents the seizure signal from being supplied to the multiplexer unit after the lapse of the predetermined time. A second hold circuit continuously supplies a related trunk of an exchange with an answer signal supplied from an answer supervisory circuit even after the fault is detected.

摘要： A rolling bearing includes an outer raceway, an inner raceway, a plurality of rolling elements interposed between the outer raceway and the inner raceway, and a cage for holding the rolling elements away from each other at the same interval in a rolling direction of the rolling elements, the cage including a first layer subjected to a surface treatment of at least one of carbonitriding, phosphating, sulfonitriding and gas soft nitfriding, and a second layer formed of at least one of PTFE, MoS.sub.2, WS.sub.2, Ag and Sn when the first layer includes a treated surface subjected to the surface treatment of phosphating. The rolling bearing can stabilize the attitude of the rolling elements and retain the ease of grinding them. At the same time, the dynamic torque of the rolling elements can be minimized while insuring to prevent the rolling elements from falling away from the cage.
