摘要： PROBLEM TO BE SOLVED: To improve the performance of an electric motor by reducing eddy current loss.
SOLUTION: A stator core assembly to be used for an electrical appliance is provided. The stator core assembly includes a plurality of core members. Each core member forms the circular arc part of the stator core assembly. Each core member includes at least two core blocks, with each core block being adjacent to each other. Each core block is formed of ferrous magnetic metallic granular body and powdery material which is mutually insulated overall. The ferrous magnetic metallic granular and powdery material is compressed and molded with the core blocks.

摘要： PROBLEM TO BE SOLVED: To provide a wide initial contact area between the pin of a bush for a roller chain and the bush. SOLUTION: A milled or rolled bush 18 of which a roller chain 10 consists comprises an opening part 22 for removing a stress situated at a central part along a joint; and recesses forming a taper-form flank formed in bush end parts 34 and 36. The bush end parts 34 and 36 are press-fitted in first and second mounting holes 28 of a bush link plate 12, whereby deformation of the bush end parts 34 and 36 is suppressed to a minimum. The recess is formed such that, before molding of the bush end parts 34 and 36, a specified spot in direct opposition to the joint of the bush 18 from the viewpoint of diameter is locally deformed or machined. In this case, when, during press-fitting of bush end parts 34 and 36 in the first and second mounting holes 28 of a bush link plate 12, the occurrence of barrel deformation phenomenon of the bush 18 is suppressed and a chain is assembled with a recess situated at a stress centralization point along the pitch line 32 of a chain, the occurrence of initial wear between the pin 16 and the bush 18 due to an initial chain drive load is decreased.
