摘要： PROBLEM TO BE SOLVED: To make clear the replacing time while preventing strength from lowering due to friction by fitting a sliding plate having flat bottom face fixedly to a sheath and projecting a shoe fixing bolt, secured while keeping planarity with the abutting face of the sliding plate, from the bottom face of the sheath. SOLUTION: A sliding plate 1 has flat upper surface and parts 1a, 1b to be fitted fixedly with a sheath 20 are provided, in the longitudinal, at the lower part on the side face thereof. The fixing parts 1a, 1b are enlarged and the flange parts 2a, 2b of the sheath 20 are fitted to the enlarged fixing parts 1a, 1b thus securing the sliding plate 1 to the sheath 20. Since the abutting faces of the sheath 20 and the sliding plate 1 are made flat, apparent residual thickness matches the real residual thickness when wear of the sliding plate 1 progresses and since the frictional margin of the sliding plate 1 can be equalized to the height of the flange parts 2a, 2b, replacing time of the sliding plate 1 can be made clear. Furthermore, stabilized current collecting action can be ensured because the contact area is increased and the contact resistance is decreased.

摘要： PROBLEM TO BE SOLVED: To provide a motor component excellent in corrosion resistance coated with a tetrafluoroethylene resin layer.
SOLUTION: A motor 1 comprises motor part bodies, such as brush 2, a coil 6, a brush holder 4, a spring 9, and the like. The exposed outer surfaces of the motor part bodies are coated with a tetrafluoroethylene resin layer. The corrosion-resistant tetrafluoroethylene resin layer provides the motor part bodies with high corrosion resistance. Since the material cost of the tetrafluoroethylene resin layer is lower than that of gold plating and the like, the production cost also becomes low.

摘要： PROBLEM TO BE SOLVED: To suppress wear of a sliding surface of a sliding member sliding together with a rotating body and to simply and easily form a dynamic pressure generating groove on the sliding surface.
SOLUTION: A shaft body 3 is rotatably supported on a bearing body 1. The shaft body 3 has the bearing body 1 and a ring 7 abutting in a thrust direction. A resin film layer 4 is printed and formed on an end face 1A of the bearing body 1 sliding together with the ring 7. The dynamic pressure generating groove 6 is formed on the end face 1A of the bearing body 1 sliding together with the shaft body 3 by the resin film layer 4. As a result, the shaft body 3 and the resin film layer 4 are slid, and wear of the bearing body 1 and the dynamic pressure generating groove 6 can be suppressed.

摘要： PROBLEM TO BE SOLVED: To effectively reduce the frictional resistance and improve the durability, in a sliding member. SOLUTION: These sliding parts are manufactured by means of charging raw powders 1 and 2 of iron-base and copper-base, respectively, into a charging part 16 of a forming die 11, pressurizing the raw powders 1 and 2 into a green compact 6, and sintering the green compact 6 into a bearing 5, wherein the copper-base raw powder 2 is a flat powder having a larger aspect ratio than that of the iron-base powder 1, and is segregated in a sliding face 51 side by vibration. The provided bearing 5 has the sliding face 51 covered with copper, and has an iron content increasing from the sliding face 15 toward the inside. When a rotating shaft slides on the sliding face 51 covered with the copper, the rotation is smooth, because coefficient of friction between the rotating shaft and the sliding surface 51 is low. Simultaneously, predetermined strength and durability can be provided by iron. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a sintered alloy which has superior corrosion resistance and can assure dimensional accuracy of the product. SOLUTION: This manufacturing method comprises compacting and sintering (S2) a base powder containing copper into a main body of the sintered alloy, plating (S4) the main body with tin, and sizing it (S5). At the sizing step, the tin plated layer is compressed to form the thickness approximately uniform, and simultaneously the pores which open to the outer surface of the main body are blocked with the tin plated layer. Moreover, combining a copper-base sintered alloy with tin plating gives the sintered alloy corrosion resistances both to sulfur and compounds thereof, and to organic acids such as formic acid and acetic acid.
