Title: Cleaning method of heat fixing roller
Inventor: TARUMI NORIYOSHI
IPC: G03G15/20
Filed: 1977-12-20
Abstract: PURPOSE: To perform sure cleaning over a long term by using an elastic blade composed of toner adhesive material.  
     CONSTITUTION: A cleaning blade 12 which is composed of silicone rubber, fluorine rubber, polymide film or the like being heat-resistant and elastic material to which release type toner is easy to adhere is secured to a crossing member 10 by way of a holding plate 11 and screw 13 and the end part thereof is pressure-contacted to the surface of a fixing roller 3 in such a manner that the end side face 12a faces the speed vector direction of the fixing roller 3 at the pressure contact point. Then, the toner having deposited on the surface of the fixing roller 3 adheres to the end side face 12a on account of its high cohesiveness and is subsequently accumulated in laminar form. This is then pushed up by the heating by the fixing roller 3 and subsequent shearing force by the toner. Hence, even when the copying machine has been continuousely used for a long time, good cleaning effect may be sustained.

IPC: H01J29/04
Filed: 1983-08-24
Abstract: PURPOSE:To stably generate an electron beam with high current density by forming three edges or more on the anode opposed surface of a cathode and arranging the intersection of these edges in matching condition with an anode small opening. CONSTITUTION:Three edges 14 or more are formed on a surface, opposed to the anode 21, of a cathode 13 and the intersection 15 of these edges and the small opening 22 of the anode are installed on the same axis.

Abstract: PURPOSE:To form a satisfactory electrostatic latent image by providing a base made of a material having a thermal expansion coefficient equal to or near that of a first insulating board in a third electrode, and conducting the surface of the board of the side opposed to an second electrode. CONSTITUTION:A recording head 1 is manufactured at an ambient temperature, heated to a temperature of approx. 60-75 deg.C to be used for the formation of an electrostatic latent image. In this case, since a base 12 for forming a screen electrode (third electrode) 3 is formed of a material having a thermal expansion coefficient equal to or near that of a first insulating board 5, the deformed amounts of the board 2 and the electrode 8 upon thermal expansion are the same or substantially the same. Thus, no large positional deviation occurs between the position of the openings 5 of electrode provided on the board 2 and particularly control electrodes 4, 4,... and that of the opening 10 formed at a polarized pole 8. Accordingly, ions generated by a creeping corona discharge generated in the opening 5 of the electrode 4 are efficiently output from the opening 10 of the electrode 8.

IPC: B01D63/02
Filed: 1994-07-05
Abstract: PURPOSE:To conduct good patting regardless of the kind of a hollow-fiber membrane at the time of coating the end of the bundle of the membranes by rotating the bundle and injecting a coating agent into the end of the bundle. CONSTITUTION:When the end of the bundle of hollow-fiber membranes 6 is coated, the bundle is rotated, and a coating agent is injected into the end of the bundle. Namely, the coating agent is centrifugally applied on the end of the membrane 6, the excess coating agent is centrifugally shaken off, and the impregnation with the coating agent is prevented. Further, a coating of optional thickness is applied at an optional position by adjusting the application position, viscosity and centrifugal force (revolving speed) of the agent. Consequently, the partial coating of the hollow-fiber membrane which has been difficult in the state of long fiber immediately after filature, is ideally applied. Further, a hollow-fiber membrane module without generating an impermeable fiber and using the membrane area efficiently is produced.
