摘要:
A hydraulic valve lifter for an internal combustion engine of the type in which a liquid introduced into a confined chamber in the valve lifter is compressed by a plunger so that the pressure of the compressed liquid causes a valve of an intake or exhaust port of the engine to open, is characterized in that an internal mechanism which regulates the time for initiating the compression of the liquid in the confined chamber in response to the change in the running condition of the internal combustion engine is incorporated in the valve lifter for making the valve operating characteristics optimum for the varying running conditions of the engine.

摘要:
A coating film-forming method that includes a first step that involves coating a cationic electrodeposition coating composition (A) containing an electrically conducting agent, followed by washing with water and heat curing and drying to form a cured cationic electrodeposition coating film. A second step that involves coating such an anionic electrodeposition coating composition (B). The coating film formed therefrom has a chromatic color or a white color as an achromatic color onto the cured cationic electrodeposition coating film. This is followed by washing with water, and removing water by preheating or air blowing to form a non-cured anionic electrodeposition coating film. A third step that involves coating a topcoating composition (C) thereonto to form a non-cured topcoating film, and heat curing and drying a resulting laminated coating film simultaneously.
