Title: Pre-load type differential-limitting device
Inventor: HIROTA ISAO
IPC: F16H48/38
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To produce a higher differential limitting effect and to provide an increased life for a multidisc clutch by a method wherein even when initial torque of a pre-load type differential limitting-device is a given value, the increase of a distribution factor is practicable. SOLUTION: A pre-load type limitting circuit is formed in such a manner that a rotational drive force on the input side from a differential case 1 is transmitted in a differential distribution state to the right and left output sides through a differential rotation member consisting of differential gears 4, 5, and 6 and a multidisc clutch 7 arranged between the differential rotation members 1 and 5 is connected by the press force of a press member 8 on which a pre-load is axially exerted to limit differentiation between the differential rotation members 1 and 5. In this case, a press ring 2 co-rotated with the differential case 1 is arranged between the multidisc clutch 7 and the rotation member 3 on the input side of the differential gear to brake a rotary member 3 on the input side.

Title: Cleaning device of copyimg machine
Inventor: NAGASAWA NAOKAZU
IPC: G03G21/10
Filed: 1982-02-16
Abstract: PURPOSE:To remove toner forcibly even if it sticks once by allowing a coupling member to strike a toner guide plate intermittently while moving along with the rotation of a revolving shaft, allowing the toner to slide down on the toner guide plate by fine oscillation and its own weight, and permitting the coupling member to move to bite and dig the toner layer. CONSTITUTION:A cross bar member 8a is longer than the distance between a ladder chain and the surface of a revolving shaft 4, so the coupling member 8 is hooked by the revolving shaft 4. When the rotating shafr 4 further rotates, only the coupling member 8 is inverted abruptly as shown by an arrow B with regard to the ladder chain. The distance between a toner guide plate 10 and the position of hooking to the ladder chain as the center of the rotation under inversion is shorter than the cross bar member 8a. During the inversion, the coupling member 8 falls on the toner guide plate 10 to strike it. The toner guide oscillates and the toner falls. At the same time, the coupling member 8 is intruded into the toner. According to the rotation of the revolving shaft 4, the coupling member 8 is drawn on the tone guide plater to scrape the toner by digging.

Title: Computer equipment for adopting address translation
Inventor: IWATA YOSHIHIRO
IPC: G06F12/08
Filed: 1989-02-03
Abstract: PURPOSE:To constitute a physical cache having a large capacity without increasing a cache access time by providing a translation predicting means and a translation holding means, and updating the translation predicting means by an appropriate condition. CONSTITUTION:A translation holding means 160 decides whether a physical address which translates an indirect address part of a logical address designated immediately before by a processor 100 by using the logical address designated by the processor 100 is effective or not. In the case when the address is not effective, the processor suspends or extends or retries an access. In this case, a translation support means 150 translates the present logical address and outputs a translated physical address from a translation address output line 151. At that time, a translation predicting means 130 updates a predictive physical address of an entry corresponding to a logical address before by one to the translated physical address, and updates a value of the corresponding logical address indirect address part to the present logical address. In such a way, a physical cache having a larger capacity than a page size can be constituted without increasing a cache access time.
