Filed: 1978-11-25
Abstract: PURPOSE: To enable the production of plastic ball set with a metal ball free from being positioned in an eccentric place, by first molding a part of a plastic ball by means of mold plates and by molding the rest of the ball in a subsequent process.  
     CONSTITUTION: A mold plate 11 is provided with a cavity being formed such that a semispherical concave portion 11a has the same radius as that of a metal ball and a narrow groove 11b cut therein. The other mold plate is provided with a cavity being formed such that a semispherical concave portion 12a has an equal radius to that of a finished plastic ball. After the metal ball is positioned in a given place in the cavity of the mold plate 11 and the mold plate 12 is then closed, resins are filled therein to form a semiprocessed plastic ball. The semiprocessed plastic ball is thus formed such that the metal ball 3 is set in the center of a plastic semispherical object 14 and is prevented from coming out by dint of a plastic band 15. The semifinished product is set in subsequent processing molds 16 and 17 wherein resins are filled to form a finished plastic ball set with the metal ball.

Title: Water supplying unit for bearing
Inventor: SATOU SHIYOUJI
IPC: F04B49/02
Filed: 1979-11-12
Abstract: PURPOSE: To prevent a rapid lowering of a feed water pressure until a hydraulic machinery stops due to a power failure to stop the machinery safely by mounting a fly wheel on a feed water pump which is used to feed water to a hydraulic-lubricating bearing of the pump.  
     CONSTITUTION: A bearing 2, which bears a main shaft 1 of a hydraulic machinery, is pressurized by water fed by a pump 16 to control vibration of the machinery during its rotation. As a motor 20 to drive the pump 16 stops at the moment that the power failure occurs because the force of inertia of the motor 20 is small in general, a flywheel 21 is mounted to make up for the power to extend the time until the pump stops. When hydraulically pressurizing a static pressure type bearing by the pump, the flywheel 21 is mounted on the feed water pump 16 to prevent rapid lowering in the pressure when the feed water pump 16 stops. By such constitution, the hydraulic machinary can be safely stopped without giving abnormal vibrations to the shaft 1.
