Title: Driving mechanism for photoreceptor drum
Inventor: HARADA YOSHIKAZU
IPC: G03G21/00
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent irregular image from occurring caused by the rotation irregularity of a photoreceptor drum by providing a roller brought into contact with a rolling surface formed on the photoreceptor drum having a common axis with the rotary shaft of a small-diameter gear. SOLUTION: A roller 46 is fitted to a driving shaft 42 supported by bearings 47a and 47b through a bearing 46 adjacently to the small-diameter gear for driving 41. The roller 46 is provided in order to prevent the shaft 42 from being deflected in a direction that backlash is increased when an inner gear part 31a is driven by the gear 41. Then, the outside circumferential surface of the roller 46 abuts on a circular-arc surface 38a formed on a photoreceptor unit frame 38 with the rotary shaft 35 as a center. Since the supporting position of the shaft 42 approaches the gear 41 by providing the shaft 42 with the roller 46, the backlash between the gear 41 and the gear part 31a is hardly changed from a prescribed value at the driving time. That means, since the backlash is hardly generated, the rotation irregularity is not caused and the gear part 31a is smoothly driven by the gear 41.

Title: Control method and device for vehicle brake device
Inventor: FAYE IAN
IPC: B60T8/32
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To surely detect a degree of risk to operate a brake auxiliary device in an early period when the risk is expected, by regarding at least one driving variable as a variable derived from the distance to an obstacle or the like ahead of a vehicle. SOLUTION: A relative speed Vrel of an obstacle ahead of a vehicle is read (100), and a threshold value (dPVOR/dt)0 to the change of supply pressure is selected on the basis of the relative speed Vrel (102). Then the change of supply pressure dPVOR/dt is calculated (104), and a pump and a valve of a hydraulic brake device are operated when a value of the change is over the threshold value (106) to start the rise of the brake pressure independently from a driver (108). Whether the rise of the pressure is finished or not is judged (110), the brake device is operated to lower the additional brake pressure again when the rise of the pressure is finished, and the braking force set by the driver is added to a wheel brake. Whereby the possibility of the start of the automatic braking process in an undesired state, can be prevented.
