摘要： In a hydraulic transmission apparatus, a lockup piston of a lockup clutch mechanism is placed on the opposite side of first and second friction plates from a sidewall portion of a front cover. A damper device is placed on the opposite side of the lockup piston from the first and second friction plates. An outer peripheral portion of the lockup piston is located closer to the outer periphery than an outer peripheral portion of a flange member. A part of the lockup piston is placed in a region located between first and second springs and a third spring of the damper device in a radial direction and in the range of an axial width of the third spring located closer to the lockup piston.

摘要： A surface hardening method, in which a surface layer on a thin steel plate member is stably melted and solidified to provide a high surface resistance against wear includes irradiation with a high density energy beam to melt a process surface portion of the steel member followed by rapid cooling. The melted surface portion includes a fully melted layer and an adjacent imperfectly or partially melted layer. At least the cooling to solidify the molten steel is performed in a short time period less than an austenitic transformation completion time at temperatures below melting, e.g., one-twentieth of the normal austenitic transformation time, and preferably both heating to melt the surface layer and cooling to solidify and harden the surface layer are performed in a time period less than the normal austenitic transformation completion time period. The high density energy beam can be divided to irradiate plural regions to melt the surfaces of the plural regions at the same time. The thermal capacity (or thickness) of the entire steel member can be designed to be as small as four times the thermal capacity of the process portion (or depth of melted portion) and still allow self cooling of the steel member to produce surface hardening. Additionally the melted-hardened surface has improved smoothness such as exhibited by a roughness which is only sixty percent or less of the roughness of non-processed surfaces.

摘要： The disclosed method produces a spline-grooved cylindrical member, e.g. torque converter front cover, including a cylindrical portion having a target wall thickness t2, from a plate blank having a plate thickness t1. An outer peripheral portion of a disc-shaped blank is plastically deformed by pressing it against a mandrel with the concave peripheral edge of a thickness-increasing roller, so that a thick wall portion, of a thickness greater than the plate thickness t1 of the blank, is formed in the cylindrical portion. The thick wall portion is then pressed against the mandrel by forming rollers to form spline grooves therein. Thus, the other portions of the product have a wall thickness which is not unnecessarily increased. In this manner, the wall thickness t2 of the cylindrical portion is not entirely dictated by the wall thickness t1 of the blank material. Thus, a cylindrical member resistant to high pressures acting on its axially-extending outer cylindrical portion can be produced with an optimal configuration.
