摘要:
Compositions of high lubrication and light coloration are disclosed in which a selected class of resins and rubbers is blended with a specified cured polybutadiene product. The cured product results from crosslinking more than 10% of vinyl bonds in a butadiene polymer having a vinyl bond content of not less 20% by mol in terms of its monomer unit. Also disclosed are solid lubricants comprising a specified fluorinated cured polybutadiene and compositions containing the solid lubricant.
摘要:
Lubricant compositions of high lubrication and light coloration characteristics are made up essentially of a selected mineral or synthetic oil and a selected polybutadiene. The polymeric component contains greater than 20% by mol of vinyl bonds in terms of its monomeric unit and has crosslinked more than 10% of the vinyl bond content.

摘要:
A fuel supply pump with a large fuel discharge amount and a tappet structure body, which are suitably used for an accumulated pressure-type fuel injection device that mechanically amplifies pressure, is provided. A fuel supply pump has a tappet structural body and a spring sheet, wherein a penetration portion for allowing passage of a lubricant or a fuel for lubrication therethrough by coordinating the tappet structure and the spring sheet is provided between a spring-holding chamber for holding a spring to be used for pulling up a plunger and a cam chamber for housing a cam to be used for moving the plunger up and down.

Power supplying unit to be used for supplying power to such a load as the motor for driving a submerged pump that scoops liquid out of a tank storing low temperature liquid like LNG and so forth. The power supplying unit has a ceramic sleeve fixed to the flange, a penetrating conductor inserted into this ceramic sleeve, and the ceramic sleeve and the penetrating conductor are coupled air-tightly to each other inside the flange (inside the tank) sealed outside the flange with a bellows of semi-mountain construction in cross section. The bellows has an elasticity and is mounted, when the ceramic sleeve and the penetrating conductor are linearly expanded at the maximum temperature during practical or normal use, or at the temperature slightly higher than the said level. The bellows is mounted between the ceramic sleeve and the penetrating conductor in a state where it is displaced to its maximum length due to its self elasticity. The bellows has been structured in such that it may absorb the reaction force being generated, when the penetrating conductor has linearly expanded, as a compression onto the side of ceramic sleeve for preventing it from acting as an tensile stress.

摘要:
An image recording apparatus for recording an image corresponding to an original on a photosensitive recording medium by irradiating light onto the original and converging light from the original onto the photosensitive recording medium. The apparatus includes a lens unit vertically movably supported by the frame, a plurality of position setting holes arrayed in a vertical direction of the frame, position setting means provided on the lens unit and capable of being inserted into one of the position setting holes for fixing the lens unit to the frame, urging means provided on the lens unit for urging the position setting means toward the frame to project the position setting means, actuating means provided on the lens unit for actuating the position setting means so that the position setting means retracts and moves away from the frame against urging force of the urging means when electric current is supplied to the actuating means. The apparatus further includes control means for controlling the actuating means so that when an error is detected during movement of the lens unit, electric current to the actuating means is cut off to project the position setting means by the urging force of the urging means and to fix the lens unit to the frame.
