Abstract: In a connector to be connected to a cable by an insulation displacement connection, a first housing has a holding portion for receiving the cable. A second housing holds a contact and coupled to the first housing with its rotation with respect to the first housing. The contact is adapted to be contact with a mating connector and has a pair of insulation displacement portions faced to each other with a gap and adapted to be connected to the cable by the insulation displacement connection. The holding portion is inserted into the gap following the rotation of the second housing so that the cable is clamped between each of the insulation displacement portions and the holding portion.

Abstract: An object of the present invention is to provide a sliding member which can slide for a longer period of time even in a dry state. In the present invention, sliding layers 3 are provided on the surfaces of a base material 2, and the sliding layer 3 contains polybenzimidazole (PBI) and 1 to 70 vol % of a solid lubricant. Since PBI, which is a thermoplastic resin, has higher heat resistance and also has higher material strength than PAI, PI, and EP, which are the conventionally used thermosetting resins, the wear resistance and the anti-seizure property can be improved and a decrease in material strength caused by high-temperature atmosphere, heat generation at the time of sliding, etc. can be restrained. Furthermore, the initial conformability can be improved because of high elongation percentage. Also, since the sliding layer contains the solid lubricant, the coefficient of friction can be decreased, and hence the anti-seizure property can be enhanced.

Abstract: There is provided a double-sided sliding thrust bearing of a plate shape adapted to be in sliding contact with a counterpart on each of both faces of the thrust bearing, comprising a bearing structure provided with a plate-shaped base member having an anchor effect on each of both faces thereof, and a sliding layer having a thickness not less than 30 ?m on each of the faces of said base member which sliding layer is made of a thermosetting resin-containing material. By making the thickness of the sliding layer 10 not less than 30 ?m, it becomes possible for the thrust bearing 1 to slide shoes for a longer time even when being used in a dry state and the sliding layer 10 comes to be hardly peeled off from the base member 2 because of the anchor effect of the base member 2. Further, the mechanical strength and thermal conductivity of the thrust bearing 1 can be improved by the base member 2 located between the sliding layers 10.

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: An object of the present invention is to provide a sliding member which can slide for a longer period of time even in a dry state. In the present invention, the sliding member is provided with a sliding layer 3 containing 1 to 20 vol % of bismuth powder and/or bismuth alloy powder, 20 to 60 vol % of metal powder, and 1 to 20 vol % of a solid lubricant, the sum thereof being not more than 70 vol %, and the balance being a thermosetting resin. Therefore, a large quantity of metal powder and bismuth powder and/or bismuth alloy powder are mixed with the thermosetting resin in the sliding layer 3, so that the thermal conductivity in the sliding layer 3 is improved, and hence heat does not accumulate in a sliding layer portion, by which seizure can be prevented.

Since a rod guide is constituted by a press molded product formed by press molding a sheet member, and at least a sliding surface of the rod guide with respect to a piston rod is coated with a sliding synthetic resin layer, it is possible to achieve a widely weight saving in comparison with the case of using a metal sintered housing, it is possible to secure a sufficient rigidity in comparison with the case that an entire of the rod guide is formed by a synthetic resin for sliding, and it is possible to achieve a further weight saving in comparison with the structure in which a composite sliding member is pressed.

Abstract: In prior art, the wear resistance and frictional properties of a sliding member are improved by adding bismuth, an alkaline earth metal salt or the like, but not lead, to a polytetrafluoroethylene used as a base resin, in view of the undesirable influences of lead on the environment. However, a further improved wear resistance at a high PV value has been desirable. In the present invention, a sliding member having excellent wear resistance and frictional properties even when used at a high PV value can be obtained by using a thermosetting resin as a base resin in a proportion of 50 to 80 vol % and adding thereto a PTFE with a molecular weight of 3,000,000 or more in a proportion of 10 to 40 vol % and bismuth and/or a bismuth alloy in a proportion of 1 to 20 vol %.

Abstract: A master vac (6) is connected and fixed to a dash panel (20) side via a bendable pedal bracket (1), and a striker (4) extends forward toward a longitudinal direction of a vehicle and is arranged in such a manner as to protrude a front end (4a) thereof from the dash panel (20) at a normal time when an external force is not applied.
