摘要:
A sliding surface (2) of a valve lifter (1) or a shim (3) is subjected to a gaseous nitriding to have a surface hardness of Hv 660 or higher and a thickness of a compound layer (6) of 1 to 5 μm. The nitrided layer on the surface is a dense compound layer (6) with a porosity of 5% or less.

摘要:
The heat-generating components of an integrated motor system are disposed proximate the motor body, for efficient heat dissipation, and the heat-sensitive components are segregated therefrom, physically and thermally.
