Title: Disk rotating mechanism for floppy disk device
Inventor: TAKARA KAZUHIRO
IPC: G11B19/20
Filed: 1988-07-21
Abstract: PURPOSE:To suppress eccentricity of a shaft with a simple constitution by providing a groove in a part, which faces a bearing and is packed with a lubricant, of the shaft. CONSTITUTION:A groove 23 is provided in the part, which faces a bearing 22 and is packed with the lubricant, of a shaft 21. The spiral groove 23 provided in the shaft 21 agitates the lubricant packed between the shaft 21 and a metallic bearing 22 by rotation of the shaft 21. That is, the oil pressure distribution generated by rotation of the shaft 21 is disturbed by the groove 23. Consequently, the oil pressure disturbance of the lubricant is not localized to prevent the shaft 21 from turning in the eccentric state. Thus, oil whip is prevented to suppress eccentricity of the shaft.

Title: Air intake amount control device for engine
Inventor: YAMAMOTO SHIGERU
IPC: F02D41/18
Filed: 1992-07-08
Abstract: PURPOSE:To predict atmospheric pressure accurately in a wide area by providing an atmospheric pressure prediction prohibition means to prohibit the prediction of atmosphere on an atmospheric pressure prediction means when a difference between air intake amount averaged value and air intake amount is large. CONSTITUTION:An air intake amount detected by an air flow sensor 15 and an actual charging efficiency based on the engine speed are calculated by a control unit 13. Also, using a base CE map, a reference charging efficiency is calculated based on a throttle opening and speed. In addition, the control unit 13 predicts the atmospheric pressure from the actual charging efficiency and reference charging efficiency. Then, from a ratio of air intake amount to air intake amount average value, an area where the detection accuracy of the air flow sensor 15 is lowered is judged and, in that area, the prediction of atmospheric pressure is prohibited. Thus the predicted accuracy of atmospheric pressure is increased.
