    • In a combination of the shim 5 and cam 1 for use in a reciprocating mechanism portion, the shim 5 is made of a material having a hardness higher than that of the sliding surface of the cam 1 and the sliding surface of the shim 5 is finished to within a range of the surface roughness of Rz0.07-0.2 &mgr;m in 10-point mean surface roughness and further the sliding surface of the cam 1 is provided with open pores 1b. In the above combination, the generated torque and the wear of sliding portion are minimized by selecting a shim member whose surface roughness is difficult to deteriorate due to plastic deformation by a injection pump contact with a mating member and corrosion by various impurities mixed in lubricant and the like, and providing the surface of a cam member with an oil film holding function so as to maintain fluid lubrication of the sliding surface.
    • 在用于往复机构部分的垫片5和凸轮1的组合中,垫片5由硬度高于凸轮1的滑动表面的材料制成,并且垫片5的滑动表面被完成 在10点平均表面粗糙度中Rz0.07-0.2μm的表面粗糙度的范围内,并且凸轮1的滑动面进一步设置有开孔1b。 在上述组合中,通过选择由于与配合构件的注射泵接触引起的塑性变形而表面粗糙度难以劣化的垫片构件以及混入润滑剂中的各种杂质的腐蚀以及滑动部件的产生扭矩和磨损最小化 并且为凸轮构件的表面提供油膜保持功能,以便保持滑动表面的流体润滑。

    • A fuel injection pump for high pressure injecting gasoline, fuel whose main component is gasoline or light oil having a sulfur content of 0.05% by weight or less by a reciprocation of a piston sliding relative to a cylinder, wherein at least a sliding surface of the piston to slide on the cylinder is made of ceramic and the surface roughness thereof, expressed in ten-point mean surface roughness Rz, is 0.05-0.4 &mgr;m in a direction perpendicular to the sliding direction and 0.2-0.6 &mgr;m in a direction parallel to the sliding direction while the surface roughness expressed in the ten-point mean surface roughness Rz of a cylinder sliding surface corresponding thereto is 0.2-0.8 &mgr;m in a direction parallel to the sliding direction. By using the above combination of piston and cylinder, the wear resistance of the piston and cylinder is improved, the durability thereof is improved and the production cost can be largely reduced.

    • There are provided a dust core in which, even if the surface of a heat-treated compact is ground, the insulation between soft magnetic particles on the ground surface can be ensured in the grinding step, and a method for producing the dust core.The method includes a preparation step of preparing a heat-treated compact 100 by compacting soft magnetic particles having an insulation coating and heating the resultant compact to a predetermined temperature; and a machining step of removing part of the heat-treated compact 100 using a working tool 2. The machining step is performed while an electric current is supplied with a conductive fluid 7L between the heat-treated compact 100 serving as an anode and a working tool 2 that machines the heat-treated compact 100 or a first counter electrode 5 that faces the working tool 2 with a distance therebetween, the working tool 2 or the first counter electrode 5 serving as a cathode. A bridge portion that connects soft magnetic particles to each other is removed through the supply of an electric current, the soft magnetic particles being adjacent to each other along a machined surface of the heat-treated compact 100.
