Filed: 1985-03-29
Abstract: PURPOSE:To enable automatic supplement of two grease by detecting dirtiness of used grease discharged from inside a bearing, by quantity of transmitted light and by supplementing grease according to difference between transmitted light quantities of used grease and new one. CONSTITUTION:New grease pressed into a bearing part 1 pushes used grease inside the bearing out to an exhaust passage 3 and through the narrow gap 7 of a detector 5. When almost no transmitted light reaches the light receptor 10 of the detector 5 after being blocked by the dirtiness of grease, difference between detected values of the detector 5 and a detector 4 of the supply side becomes larger to mark the biggest grease supply power. When new grease is mixed to gradually increase transmitted light of the grease passing through the gap 7 of the exhaust side detector 5, power of grease supply decrease.

IPC: H03H9/02
Filed: 1980-05-21
Abstract: PURPOSE:To achieve low loss and low ripple, by providing a reflector for reflecting wave generation, in the range of the width of a cross finger transducer, for either one of transmitting or receiving transducer. CONSTITUTION:Reflecting components are suppressed at a receiving transducer 3, and a reflection wave 8 is returned to a transmitting transducer 2.
