Title: Gas insulated switch gear and conductor holding post of the same
Inventor: WATANABE TAKAHIDE
IPC: H02B13/02
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To make it possible that a charging means is never exposed to the outside and make it unnecessary to provide a tank to the external side by insulating a supporting conductor with a conductor holding post, and then providing to an air-tight conductive electrode. SOLUTION: A conductor holding post 13 is composed of an insulator and is provided with a fitting means at an air-tight conductive electrode 71 for fitting with a screw hole 131 at a flange 15 of one end thereof, and a flange 15 at the other end to fit the supporting conductor 2. Shape of flange 15 is identical to that of the flange of supporting conductor 2, namely the diameter of flange 15 is set larger than the diameter of air-tight conductive electrode 71 while diameter of screw, screw pitch, number of screws and outer diameter of flange are identical and thereby it is also possible that the air-tight conductive electrode 71 fitted is perfectly covered with the flange 15. The airtight conductive electrode 71 is exposed to the outside but it is safe because it is insulated by the insulating post 13 and is never operating as the charging means.

Title: Transcription conveying belt
Inventor: GOTODA KATSUHIKO
IPC: G03G15/00
Filed: 1988-04-05
Abstract: PURPOSE:To surely attract recording paper to be conveyed after its transcription performing the transcription of high quality by forming a porous dielectric layer, having many fine through holes or recesses, on a conductive layer. CONSTITUTION:A dielectric layer 6, formed on a conductive layer 5, is of porous quality having many fine through holes 7 or recesses 8. Consequently, a toner minus charge is placed in a solid part of the dielectric layer not forming the through hole 7 or the recess 8, even when a surface potential in the solid part decreases, an electric field by the other potential of the conductive layer 5 acts through the through hole 7 or the recess 8. Thus a drop of the surface potential is suppressed as the total unit of the dielectric layer 6. While the action is similarly performed in case of toner having a plus charge. Accordingly, a toner image on a sensitive unit can be surely transcribed on recording paper, and it can be surely attracted and conveyed after the transcription while enabling its high quality to be attained.
