Title: Bearing device
Inventor: UNO SHIYUUETSU
IPC: F16C37/00
Filed: 1979-03-19
Abstract: PURPOSE: To prevent damage and abnormal vibration by providing a long circumferential groove not reaching the divided surface between the upper half bearingcooling groove and both ends and by dividing oil into the cooling groove and the long groove.  
     CONSTITUTION: The oil supplied from an oil supply hole 3b of the lower half bearing 3 flows into a bearing gap being divided in the cooling groove 2b and in the two long grooves 2c by a parting plate 3e set up in an oil pooling groove 3d. The oil in the long groove 2c flows out of the sliding surface as indicated by an arrow showing the positive pressure. In case the inside of the cooling groove 2b becomes negative-pressure on account of failed oil, even if desired to draw in air from the bearing end, the air intermixture from the bearing end is completely checked because of the sliding surface positive pressure. In this way oil film ridigity increases, critical speed improves, oil film break is eliminated, finally abnormal vibration and damage are prevented.

Abstract: PURPOSE:To perform mode switching without providing any dedicated mode changeover switch by providing a control system which detects that a key for indicating frequency variation is pressed for a prescribed time or longer and performs switching from a manual mode to an automatic mode. CONSTITUTION:An indication signal generated by the key operation of an operation part 8 is supplied to an arithmetic circuit 17 through a decoder 12. The arithmetic circuit 17 monitors the operation time of the key, and when the key is pressed for the prescribed time or longer, the judgement of the state of the key is repeated without generating any stop signal C after one-step up or down operation. Then when the key operation is ceased, the monitoring of the operation time of the next key is started after the one-step up or down operation, and when no key is operated, the one-step up or down operation is restarted. When the signal C is confirmed, a decision on tuning is made and said operation is stopped to enter the automatic mode, but the arithmetic circuit 17 carries out said operation to control a programmable divider 19, performing tuning in corresponding modes.
