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.

Abstract: A sheet electrode with a predetermined thickness for an electric double layer capacitor is made by carrying out a roller rolling step in which a long sheet intermediate is made from a material containing a carbonaceous powder, a conductive assistant and a binder and thereafter. The sheet intermediate is passed between a pair of rolling rollers to be wound up by a winding section while being drawn out of a drawing section. The roller rolling step includes drawing the sheet intermediate out of the drawing section under a predetermined tension applied to the sheet intermediate, and controlling a widthwise position of the sheet intermediate immediately before the rolling rollers by an edge position controller, and winding the sheet intermediate rolled by the rollers onto a winding section while the winding section is applying a predetermined pressure to a rolling side drive roller located adjacent to the winding section and rotated at a predetermined speed.

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 %.
