Title: Apparatus for reproducting information record carrier
Inventor: EBINUMA NAOTAKE
IPC: B29C45/27
Filed: 1984-10-19
Abstract: PURPOSE:To avoid that ground powder resulting from sliding is mixed into a radiation-curing resin that is discharged for forming an information record carrier transferring surface, by sucking and discharging ground powder that is formed near a sliding section of a slide pin for controlling the amount of the discharge. CONSTITUTION:Ground powder resulting from sliding at a sliding part 7 is carried by a radiation-curing resin flowing toward a pipe 9 and is pushed outside of a discharge nozzle, so that the ground powder would not be discharged between a plastic base plate 1 and a copying metal stamper 2. If, additionally, a suction mechanism is incorporated on the tip side of the pipe 9 and suction is carried out synchronously with the operation of a slide pin 5, the effect becomes remarkable. It is important, in practice, that an inflow side pipe 6 is to be located nearer to the base plate 1 than to the discharge side pipe 9, and the greater the distance (a), the better the effect. It is better that the attached position of the pipe 9 is nearer to the sliding section 7, and good results will be obtained by providing many such pipes 9.

Title: Data transfer control system
Inventor: KOSUGE HIROSHI
IPC: G06F13/362
Filed: 1989-08-25
Abstract: PURPOSE:To prevent the generation of a state increasing switching overhead due to the frequent switching of transfer requesting sources by preventing a certain processor from being interrupted by a transfer request from another processor until the end of the specific volume of data transfer. CONSTITUTION:Respective processors 10(1) to 10(n) detect that the volume of continuous data transfer reaches a specific value X and send continuous transfer end commands to a competition control part 20a together with block transfer requests.

Title: Metal-made handle and door
Inventor: WADA NOBUYUKI
IPC: E05B1/00
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To ease a shock caused by electro-static discharge received on a human body by arranging electrically conductive resin of high resistance at a region where a metal-made handle is brought into contact with a metal-made door body, and setting the resistance value of the electrically conductive resin and a distance from a handle member to the door body within a specified range. SOLUTION: A metal-made handle is constituted of a handle member 1 and a door body 2. A metal-made door is constituted of the handle member 1, the door body 2 and electrically conductive resin 3. Even in the case where electro- static voltage electrified on a human body is generally 10kV or higher, the resistance value of the electrically conductive resin 3 is made about 10MΩ to about 10GΩ from the viewpoint of safety on which a shock received on the human body is eased. In order to maintain the electrically conductive resin in high resistance, current causes atmospheric discharge between the handle member 1 and the door body 2. In this case, a distance from the handle member 1 to the door body 2 is enlarged, and atmospheric discharge can be prevented by forming the distance of the electrically conductive resin 3 within about 7mm to 15mm.
