    摘要： 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.

    摘要： 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.

    摘要： A soft magnetic material includes a plurality of composite magnetic particles each including a metal magnetic particle and an insulating coating film covering the metal magnetic particle. Each of the plurality of composite magnetic particles has a ratio Rm/c of a maximum diameter to a circle-equivalent diameter of more than 1.15 and not more than 1.35. The insulating coating film is composed of a thermosetting organic material and has a pencil hardness of 5H or higher after thermosetting. With this material, an eddy current loss can be reduced, and a compact with a high strength can be formed.
