摘要： After forming a primary powder bed at a toothed portion of an article, such as a gear or a spline shaft, by electrostatic powder coating process, the powder bed is removed from crests of teeth in the toothed portion by a specified thickness by scraping it off while sucking up the scraped powder. Next, the electrostatic powder coating process is performed again to form a secondary powder bed over the entire surface of the toothed portion. Then, the primary and secondary powder beds are melted or fused by induction heating to thereby form a coating film of a substantially uniform thickness.

摘要： A resolver includes: a resolver rotor attached to a rotational shaft; an annular resolver stator that is provided on a radially outer side of the resolver rotor and that has a plurality of teeth each opposed, across a clearance, to an outer peripheral face of the resolver rotor and circumferentially arranged at given intervals; and a case member having a cylindrical fit portion to which an outer peripheral face of the resolver stator is fitted. At least three protrusions, each protruding radially outward, are formed at given circumferential intervals on the outer peripheral face of the resolver stator, so that the outer peripheral face of the resolver stator is press-fitted to an inner peripheral face of the fit portion at positions at which the protrusions are formed.

摘要： Provided are a spline joint (1) where a section at which a male spline shaft (2) and a female spline shaft (3) mesh is filled with a lubricating agent composition containing a lubricating oil and buffer particles (B), and the lubricating agent composition. Impact caused by meshing of both spline shafts (2, 3) is buffered by the buffer particles (B) placed in the section at which both spline shafts (2, 3) mesh. As a result, chattering sound and sliding resistance can be stably reduced for a longer time without having wearing and peeling which occur in coating.
