Title: Magnetic developing device
Inventor: KAWANO YUZO
IPC: G03G15/09
Filed: 1987-08-07
Abstract: PURPOSE:To prevent toner from being deposited on the surface of a developing sleeve even after long-period use by putting a developer in a turbulence flow with the repulsive magnetic force between 2nd and 3rd magnets and removing toner from the surface of the developing sleeve by the turbulence flow together with carriers. CONSTITUTION:Outside magnetic poles of 1st, 3rd and 4th magnets 3, 5, and 11, i.e. magnetic poles opposing to the inner periphery of the developing sleeve 2 and S poles and that of only a 2nd magnet 4 is an N pole. When the developing sleeve 2 rotates, part of the napped developer 9 is inhibited from moving with the repulsive force between the 4th magnet 11 and 3rd magnet 5 and a turbulence flow of the developer (encircled with a broken line) is generated at the napping part. This turbulence flow brings toner and carriers which stick on the surface of the developing sleeve 2 or are to stick into sufficient contact and the toner on the surface of the developing sleeve 2 sticks on the carriers with static electricity generated at the time of contacting and is conveyed and scraped off by a scraping-off plate 8 together with the carriers. Consequently, the sticking of the toner on the developing sleeve is suppressed.

Title: Tableware washing machine
Inventor: MATSUNO TOMOHIKO
IPC: A47L15/42
Filed: 1994-08-23
Abstract: PURPOSE: To ensure a sufficient water sending amt.while enhancing reliability, in a tableware washing machine wherein a valve mechanism is interposed between a nozzle and a washing pump, by improving the valve mechanism. CONSTITUTION: When a thermo-actuator is set to a current non-supply state, a stopper 55 is not moved and the rising route of a ball valve 54 is opened. When washing is started, the ball valve placed on a placing part 52 is pushed up by washing water to close the inflow port 49 to a tower nozzle 24. By this mechanism, washing water is ejected only from an arm nozzle 21. When the thermo-actuator is set to a current supply state, the stopper 55 falls forwardly and the rising route of the ball valve is closed. In this state, the ball valve pushed up by washing water is stopped by the stopper and the inflow port to the tower nozzle 24 is not closed. By this constitution, washing water is ejected from both of the arm nozzle and the tower nozzle.

Title: Scratch repairing method for information recording disk
Inventor: YAGUCHI SADAO
IPC: G11B23/50
Filed: 1990-07-27
Abstract: PURPOSE:To repair an information recording disk and to reproduce again the information by dropping the resin onto the surface of the disk, flattening the resin on the disk by the centrifugal force, and hardening the resin. CONSTITUTION:When a scratched compact disk 6 is to be repaired, the rotational frequency of a motor 1 is reduced and the ultraviolet ray hardening resin is dropped on the revolving disk 6 at a point near the center with use of a filler 8. Then the rotational frequency of the motor 1 is gradually increased and the resin is evenly spread over the surface of the disk 6 by the centrifugal force. Thus the scratches are repaired on the disk 6. At the same time, the extra resin is blown away and only the necessary resin remains thin and evenly. Then the repaired disk 6 is irradiated by the ultraviolet rays through an ultraviolet ray radiator 9 and the resin is hardened. Thus the scratches caused on the transparent resin surface of an information recording disk can be repaired and the recorded information can be reproduced again.
