Abstract: PURPOSE: To provide a rolling bearing suitable for using under special environment where fluid lubricant can not be used by forming at least one of components having a contact face, which causes rolling or sliding friction, of a condensed polynuclear aromatic resin(COPNA). CONSTITUTION: A rolling bearing is composed of an inner ring 1 fittedly attached to a rotating shaft; an outer ring 3 fitted on the fitting face of a housing 2 with a loose fitting clearance S provided between them; a plurality of balls 4 existing between an inner and an outer ring 1, 3; and a cage 5 to hold the balls 4 at circumferential equal spaces. In this case, the outer ring 3 is formed of COPNA resin. The inner ring 1 and the ball 4 are formed of martensite system stainless steel for example SUS440C, and the cage 5 is formed of SUS304. Thus the outer ring 3 composed of the COPNA resin having self- lubricating ability fulfills a duty as a lubricant supply source to dispense with the use of the lubricant.

Abstract: PURPOSE: To control the rising time of the internal pressure of an injection cylinder and prevent the generation of flashes on a die-cast article or the like by a method wherein a pressure regulating piston formed with a through-hole is provided between the injection cylinder and a hydraulic pressure source, and the piston is moved after a molten material is charged into a mold.  
     CONSTITUTION: When an injection piston 13 is advanced after feeding a molten material into an injection sleeve 18, the mold 17 is charged with the molten material. Then, the pressure inside a rear chamber 10b of a cylinder main body 11 is raised, and when the pressure reaches a desired value, a sequence valve 24 is opened, so that an oil in a front chamber 9b flows into a tank 22 through the valve 24 and a flow control valve 21, causing the pressure regulating piston 14 to move in the direction of the injection piston 13. In this case, since the velocity of the piston 14 is controlled by the control valve 21, the internal pressure of the injecton cylinder 10 is controlled by the piston 14 after the piston 14 starts to move. Accordingly, the rise in the pressure of the cylinder 10 can be controlled in accordance with a solidified layer at the surface of the molten material in the mold 17.
