One or more of constructional members of a hydrodynamic bearing assembly are nickel-plated, and the members to be welded and fixed are arranged to abut on one another. The nickel plating is performed so as to form a plated layer of less than 10 μm in thickness between the members to be welded and fixed. An energy beam is applied at the joining portion of the members to be welded and fixed, to weld and fix these members.

A coil spring 60 is provided in an empty room (inside of a fixing roller 50) of a main body 52 of a roller. The coil spring 60 is in contact with an inside wall 52a surrounding the empty room of the roller main body 52 and pushes the inside wall 52a outward. The coil spring 60 and the inside wall face 52a are coated with a black film 66 except the contact portion 62 of the coil spring 60 and the inside wall 52a.

Roller insertion grooves are formed along the longitudinal direction of inner wall portions of side frames, which are provided in the interior of a housing that makes up a gate valve. Respective pairs of retaining rollers are inserted into the roller insertion grooves. A valve disk is tilted, such that in a valve closed state in which the valve disk is seated on a valve seat, a load imposed from a displacement block, which is connected to a valve rod and tiltably displaced thereby, is imposed on the retaining rollers, the load being borne by first and second pressure receiving bodies, which abut against the retaining rollers and are disposed on the side frames. The first and second pressure receiving bodies are formed from a material having a hardness greater than that of the side frames.
摘要:
In a liquid crystal display panel, a liquid crystal layer is sandwiched between a TFT substrate and a color filter substrate. An ITO film is formed on a front surface of the color filter substrate. By supplying an electric current to the ITO film at the time of staring an operation of the liquid crystal display panel, a temperature of the liquid crystal layer is elevated to a level which allows the liquid crystal layer to perform a normal operation within a short time. By forming a plating electrode on two sides of the color filter substrate, it is possible to uniformly supply an electric current to the ITO film thus enabling uniform heating of the color filter substrate.
