摘要： A roller bearing cage is made of a resin and has a tapered tubular shape as a whole. In the roller bearing cage, tapered rollers are forcibly fitted to pockets while elastically deforming pillar portions at a small-diameter annular portion side. A stress alleviating portion is provided on at least an outer circumferential side of an end of the pillar portion at the small-diameter annular portion side so that a portion of the pillar portion from a crossing portion between the pillar portion and the small-diameter annular portion to a side of the large-diameter annular portion is linearly cut, thereby alleviating the stress occurring in the pillar portion when the tapered roller is forcibly fitted to the pocket.

摘要： A method of making a coated article is provided. The method includes electrostatically depositing powder onto a metallic article to be coated using an electrostatic spray gun while the metallic article is being rotated around its axis such that the powder is deposited around the entire circumference of the metallic article at least in a radially outward peripheral region having projections and depressions and that the powder deposited on top of the projections is larger in thickness than the powder deposited in other parts of the metallic article. Melting of the powder is performed by induction heating the metallic article to make a coating film adhere to the metallic article.

摘要： A gear composed of a polymer blend or a copolymer of PA66 and PA6 which contains a part having a PA66 molecular structure and a part having a PA6 molecular structure in a weight ratio of PA66/PA6=99.9/0.1 to 95.0/5.0 is excellent in durability as well as heat resistance and dimensional stability. A speed reduction gear using the gear has a reduced size, and can be used under a higher torque without a torque increase due to dimensional change of the gear. An electric power steering apparatus using the speed reduction gear has a reduced size, and can be used for a larger automobile.

摘要： After forming a primary powder bed (i.e., powder layer) at a toothed portion of an article, such as a gear or a spline shaft, by electrostatic powder coating process, the powder bed/layer 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/layer over the entire surface of the toothed portion. Then, the primary and secondary powder beds/layers are melted or fused by induction heating to thereby form a coating film of a substantially uniform thickness.
