    摘要: A method of making a metal casting composed of a steel plate and aluminum material interlocked with the steel plate. A plurality of teeth are formed on at least one of the opposed surfaces of the steel plate by raising up a skin of the plate from the same, the teeth providing primary interstices, each of which extends from the steel plate and has at least one face with a number of flaws formed during the formation of the teeth and providing substantially irregular interstices. The casting is then formed by pouring aluminum material in the molten state onto the steel plate surface so that the molten aluminum material penetrates into the primary and irregular interstices, thereby to provide a firm interlocking between the steel plate and the aluminum material upon solidification thereof.

    摘要: In a bearing constituted by a plural-layer slide member, the plural-layer slide member comprises a resin layer of polytetrafluoroethylene as a slide member and a backing strip to which the resin layer is bonded. A fitting hole having a depth exceeding the thickness of the resin layer is formed from the resin layer side. A temperature measuring metallic member formed of a white metal is fitted in the fitting hole. A temperature sensor is positioned within the temperature measuring metallic member. This bearing permits an accurate detection of its temperature. Further, in an oil cooled screw compressor having a bearing lubricating oil supply pipe, a slide surface of the bearing is covered with polyether ether ketone. Even if foaming occurs in the oil, it is possible to prevent the occurrence of a mechanical trouble such as galling.
