Title: Rotary device and method and device for adjusting pre-load on rotary device
Inventor: MARUYAMA FUMIO
IPC: B23P19/06
Filed: 1986-09-13
Abstract: PURPOSE:To prevent generation of noise and rattle in a rotary shaft of a differential gear device for an automobile by applying pre-load to bearings through plastic deformation of a bent portion of a collapsible spacer provided between the bearings and elastic force of the whole structure. CONSTITUTION:In order to adjust pre-load on a rotary device (differential gear device) 1, a drive pinion shaft 3 is first supported through tapered bearings 4a, 4b by a gear carrier 2, and a collapsible spacer 5 is interposed between the bearings 4a, 4b. Then, a nut 9 is screwed on a threaded portion 3c of the shaft 3. A nut box 24 is engaged with the nut 9 of the rotary device 1. When the box 24 is rotated, the nut 9 is fastened to force the flange companion 6 to the left. As the result, the spacer 5 is pressed through an inner race 4d of the bearing 4b. This causes compressive stress to occur in the spacer 5, and the reaction force thereof applies pre-load to the bearings 4a, 4b.

Title: Source voltage generating circuit, and semiconductor integrated circuit
Inventor: SEKIMOTO YASUHIKO
IPC: G05F3/24
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To provide an intermediate-voltage generating circuit which is reduced in power consumption. SOLUTION: A reference voltage is generated by resistances 11 and 12. The midpoint X is connected to the gates of P1 and N2 and also connected to the drains of P2 and N1. A saturation connection between the P2 and N1 is made and their sources are connected to the drains of the N2 and P1. The gates of the N1 and P2 are connected to the gates of N3 and P3 connected in series between a positive power source VDD and a negative power source VSS. In this case, the N1 and P2 operate at the limit of a threshold voltage, so the gate of the N3 is biased to a voltage which is the threshold voltage higher than the reference voltage and the gate of the P3 is biased to a voltage which is the threshold voltage lower than the reference voltage. Therefore, the value of a current i3 becomes 0 in a stationary state and an intermediate source voltage generating circuit 10 consumes little electric power.

Abstract: PROBLEM TO BE SOLVED: To provide a vehicle sharing system capable of smoothly executing renting processing of a shared car because of executing the renting processing without using a terminal equipment and enabling a user to reserve the car when the user leaves the car temporarily. SOLUTION: In the vehicle sharing system, an ID receiver 25 reads an ID characteristic to a user from an IC card storing this ID through a door antenna 24 and outputs it to a CARD-ID managing UNIT.23. Then, the UNIT.23 stores this read ID in an ID storing device 29 to execute renting processing. Thus, when the ID is stored in the device 29, renting of this shared vehicle is rejected and the UNIT.23 permits renting of this shared vehicle when the ID is not stored in the device 29. When the user selects reservation by a return/reservation selecting switch SW.28, the IC card is ejected with the ID stored in the device 29, so that the user can temporarily leave from the shared vehicle carrying with the IC card.
