Abstract: There is provided a sliding member having excellent frictional wear properties not only under non-lubrication and under oil-lubrication but also under boundary lubrication. The present invention provides a multilayer sliding member including a porous metal layer formed on a sheet of back metal and a resin layer impregnated into and coated on the porous metal layer, wherein the above described resin layer contains 1 to 25 vol % of an oxybenzoyl polyester resin, 0.1 to 5 vol % of a hard particle material, 1 to 5 vol % of an inorganic compound, and polytetrafluoroethylene. Particularly, the addition of the inorganic compound enhances the oil-retention property under boundary lubrication, so that the frictional wear properties under boundary lubrication can be improved pronouncedly.

Abstract: The invention provides a method of processing an inner surface of a bearing having a cylindrical shape which bearing includes a resin layer composed mainly of a synthetic resin as the inner surface, the method improving roughness of the inner surface and dimensional accuracy of an inner diameter of the bearing without cutting the inner surface. According to the method, the bearing is press-fitted into a jig and then the jig is mounted on a chuck. Next, a mandrel having a cylindrical bar shape is inserted into an inner diameter portion of the bearing and then the mandrel is heated by a heater up to 250° C., for example. The mandrel is expanded due to thermal expansion by the heating so that the inner surface, i.e., a surface of the resin layer is pressed by a press face of a peripheral surface of the mandrel.

Abstract: A micro relay is provided including a movable contact, a stationary contact, and a ground contact opposed to the movable contact. In an operating state, the movable contact touches the ground contact when the movable contact separates from the stationary contact. In a non-operating state, the movable contact remains separated from the ground contact so that the movable contact does not stick to the ground contact. Since no parasitic capacitance is formed between the stationary contact and the movable contact, the isolation property of the micro relay is improved.

Abstract: A multiplex security system provides two-way data communications between a local panel and multiple microprocessor-based remote panels interconnected over a common data transmission line. A second line provides two-way voice communications between the local and remote panels with automatic forwarding by an audio/data control selector to a central control unit via a single telephone line. Two additional lines provide a common ground and transmit DC power from the local to the remote panels. The remote panels include bus drivers connected to the communications line for transmitting both ASCII digital data messages and a higher voltage request or SRQ signal to the local panel when the remote panel has a message to transmit. The local panel includes two separate receivers for distinguishing the request signal from digital data and a bus driver for transmitting data. The local panel transmits a grant message which is superimposed over the request signal, reducing its voltage level to zero. The remote panel has a receiver for receiving ASCII data from the local panel and for sensing the reduced voltage level to turn off the request signal. The remote panels are assigned priorities by setting different switch numbers in each panel. The switch numbers correspond to unique brief time slots in which each of the remote panels can commence transmitting. Following a grant command, the remote panels count time slots. None can respond until the count equals its respective switch number, and then only if another panel has not already commenced transmitting.
