Title: Control method for image forming condition
Inventor: ASO TAKAKO
IPC: G03G15/04
Filed: 1992-02-20
Abstract: PURPOSE:To decrease drop of the intermediate tone reproducibility and reduce contamination on the ground surface of an image or wasteful consumption of toner by lessening the toner attachment to the non-image portion of an electrostatic latent image on a photo-sensitive drum due to drop of the electric resistance in the process of forming images by the use of a developing roller having such a trait that the electric resistance varies with environment. CONSTITUTION:The non-image forming region in the same potential state as the non-image portion of an electrostatic latent image on a photo-sensitive substance drum 1 is passed through the part confronting a developing apparatus 4 on which the same development bias as during image formation is impressed, and the toner attachment amount is sensed by an optical sensor 3. Also the region is passed through the part confronting the developing apparatus 4 with a development bias impressed which has been changed so that the potential difference from the region is made greater than the development bias, and this toner attachment amount is sensed by the optical sensor 3. If the later amount of toner attachment is greater, it is judged that a drop has occurred, and the development bias during image formation is corrected so that the potential difference from the non-image portion lessens.

Title: Damper unit for opening and closing door
Inventor: KANBARA SHINJI
IPC: H04N5/64
Filed: 1988-03-25
Abstract: PURPOSE:To form a mechanism for opening and closing a door by using a hinge and not using a gear, by installing a member to retain the free end of a holding shaft of a hinge in such a manner as to be able to rotate, and making the member further fix and hold an oil damper main body, said hinge being inserted with pressure into the rotary shaft of the oil damper main body and fixed to the shaft. CONSTITUTION:An oil damper main body 1 is fixed to a damper unit retaining metal member 9 with screws. An A hinge 8 has a small shaft 8 arranged so as to protrude from a retaining shaft 8a. The small shaft is retained by a hole 9a of the damper unit retaining metal member 9, in such a manner as to be able to rotate. As a result, the step-part on the small shaft and the retaining shaft 8a prevents the A hinge 8 from getting out of the rotary shaft of the oil damper main body. When a door 4 is opened, it rotates around a center axis 12 because of its self-weight. This rotation is transferred to a protruding shaft 8b installed on the A hinge 8 of a damper unit, via a C hinge 14, and rotates the oil damper main body 1 to generate damper effect. Thereby the door is opened smoothly.

Title: Continuous expression filter device
Inventor: YOSHIMOTO TAKEFUMI
IPC: B30B9/24
Filed: 1985-04-08
Abstract: PURPOSE:To improve the dehydrating efficiency of a material slurry by interposing upper and lower belt-like filter cloths into the spacing between a filter plate on the outside circumferential surface of a cylindrical drum under rotation and an endless tracked vehicle which contacts with and detaches from said filter plate at specified intervals and providing a pressurizing member for expressing the material slurry between the two filter cloths. CONSTITUTION:A drum shell 2 is rotated by worm reduction gear devices 4, 5 and the cake between two sheets of the belt-like filter cloths 9 and 9' is brought into contact with the filter plate 8 on the outside surface of the drum by the endless tracked vehicle 10. Guide rollers 10 of fixtures 11 attached to the side faces of the drum are pressed onto the endless tracked vehicle 10 on the drum by guide rails 13 in a expressing part (the lower part of the drum). A diaphragm 7 inflates toward the outside by water or air and presses the plate 8 toward the outside of the drum, thereby dehydrating the cake existing in the endless tracked vehicle 10 supported by the fixtures 11 and the filter plate 8. The endless tracked vehicle 10 and the filter cloths 9, 9' detach from the drum in the non-expressing part on the upper side of the drum. The rollers 12 of the fixtures 11 are removed from the endless tracked vehicle 10 by the rails 13 in this stage.
