Title: Stem installing device of drift tube accelerator
Inventor: TAKEDA OSAMU
IPC: H05H9/00
Filed: 1995-01-17
Abstract: PURPOSE: To facilitate positioning and the positional adjustment of a drift tube, and reliably hold electric contact between a stem and a cylindrical accelerating cavity. CONSTITUTION: A flexible annular plate 24 is arranged in a collar shape on a stem 4, and the annular plate 24 is arranged in a wall part of a cylindrical accelerating cavity 1, and a through hole 21a is sealed in a vacuum. Therefore, the stem 4 can be installed in the same position with a wall surface of the cylindrical accelerating cavity 1 through the annular plate 24. Therefore, since a position adjusting-fixing mechanism to support the stem 4 can be installed in the outside vicinity of the cylindrical accelerating cavity 1, the stem 4 can be shortened. When positioning and positional adjustment of a drift tube are performed by the position adjusting-fixing mechanism, the axial directional moving distance of the stem 4 can be absorbed by strain generated in the annular plate 24.

Title: Reducing valve
Inventor: IKEDA KOICHI
IPC: G05D16/10
Filed: 1989-01-11
Abstract: PURPOSE:To eliminate chattering phenomenon by abutting a main valve with a driving part via a spring whose spring constant can be increased as being compressed. CONSTITUTION:The springs 29 and 31 are arranged in the inside of a cylinder 25, and the lower end of the piston bar 20b of a piston 20 is abutted with the spring 29 by inserting. Also, the main valve 18a is arranged at the entry side of a valve seat member 23 which forms a valve opening 14 by pressing elastic ally. Therefore, the main valve 18a is displaced only by 1/2 of the displacement of the piston 20 until the piston bar 20b is abutted with the spring 31 even when a pilot valve 26 is opened quickly due to the fluctuation of secondary side pressure and the piston 20 drops quickly and it tries to open the main valve 18a, and the main valve 18 is opened slightly. Thereby, no steep rise of the secondary side pressure occurs, and hereafter, constant feedback pressure without generating the fluctuation is transmitted through a diaphragm 28, the pilot valve 26, the piston 20, and the main valve 18a corresponding to the above action, thereby, the chattering phenomenon can be prevented.

Title: Rotary body for transporting image bearing sheet
Inventor: KAGIURA KAZUO
IPC: G03G15/00
Filed: 1978-01-20
Abstract: PURPOSE: To prevent offset of unifixed toner on an image bearing sheet even when the sheet is in an insufficient fixation state, by providing a rotary body having a flocked surface on the image bearing side of the sheet and by transporting the sheet keeping them in contact.  
     CONSTITUTION: A flocked resin is coated on the surface of sheet discharging roller 24 by a static flocking method utilizing static attraction. This allows the image bearing surface of transfer paper to come in contact only to the tips of flocked fibers 25, and reduces the contact area remarkably as compared to conventional rollers, resulting in reducing offset of unfixed toner to roller 24 to very slight amount. Since each contact area is like a point and uniformly dispersed, offset of slight toner, if any, on the transfer paper is hardly conspicuous and causes no problem.
