Title: Dry electrophotographic device
Inventor: HARADA TOSHIMITSU
IPC: G03G21/10
Filed: 1991-02-16
Abstract: PURPOSE:To prevent the fur of a cleaning brush from secular tilting by regularly or irregularly changing the rotating direction of the cleaning brush. CONSTITUTION:At the time of cleaning, the cleaning brush 3 is rotated in a direction A to clean a photosensitive drum 1. By meshing a 1st brush gear 18 with a 2nd brush gear 19, the brush 3 is rotated in a direction C which is opposite to the direction at the time or cleaning. The device is so constituted that bias voltage is not impressed on the brush 3 by switching the impressing means 7 of the brush 3 to a ground side as soon as the rotating direction of the brush 3 is changed. Therefore, toner is easily separated from the brush 3.

Title: Cryogenic temperature generating device
Inventor: NOMACHI HIROYASU
IPC: F25B9/06
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To reduce a driving torque by a method wherein an energizing member, energizing a rotary valve piece in a direction of separating the same from a valve plate, is provided to cancel a force, pushing both of the rotary valve piece and the valve plate from the difference between the pressure of the rotary valve piece side and the valve plate side, by the energizing member in some degree. SOLUTION: A high-pressure space 53 is positioned at the side of a rotary valve piece 38 while a low-pressure space 54 is positioned at the side of a valve plate 39. Accordingly, the rotary valve piece 38 is pushed against the valve plate 39 by a pressure corresponding to a difference between the high pressure and the low pressure. In this case, the rotary valve piece 38 is energized in a direction of separating the same from the valve plate 39 by a spring 40, arranged in the bottomed groove of the rotary valve piece 38, whereby a pushing force due to a pressure difference is canceled by the energizing force of the spring 40 in some degree. As a result, a force, pushing the rotary valve piece 38 against the valve plate 39 is mitigated whereby the rotating torque of the rotary valve piece 38 can be reduced.
