Title: Oil hydraulic pump driven by compressed air
Inventor: HIDAKA HISATOKU
IPC: F04B9/135
Filed: 1988-09-17
Abstract: PURPOSE:To prevent an oil hydraulic pump from deteriorating its function by constituting the pump such that a selecting member additionally detaches a selector valve from a stopper to switch a compressed air chamber to air exhaust and adapts the valve by separation to switch the chamber to an air feed by cam action of an engaging device and an engaging groove. CONSTITUTION:Compressed air is always fed to a compressed air chamber 14. When a plunger 9 reaches a stroke final end, a selector valve 24 advances closing a main passage 15, and the air is fed to the chamber 14 from a subpassage 16 of fine bore. When the selector valve 24 is detached from a stopper 27, an inner hole 25 is opened exhausting the compressed air in the chamber 14 to an exhaust chamber 19. While when the plunger 9 is returned to a stroke start and, the selector valve 24, reset retracing, closes the inner hole 25, and the air is fed to the chamber 14 by opening the main passage. Since the air is always fed to the chamber 14 through the subpassage 16, the plunger 9 advances, even at a very fine speed, pressurizing the air before the selector valve 24 is surely detached from the stopper 27 in the stroke final end.

Title: Magnet roller
Inventor: IWAI MASAHARU
IPC: H01F7/02
Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To realize locally high magnetic flux density without causing increase of size and electric power of magnetizing equipment, by constituting a part or the whole of a roller main body part having a plurality of magnetic poles, of a metal magnet having coercive force smaller than o equal to a specified value. SOLUTION: In a magnet roller 1, a roller main body part 2 and a shaft part 2 are formed integrally by using ferrite type bond magnetic material, and a recessed trench 4 is formed on the outer peripheral surface all over the whole length in the longitudinal direction. The recessed trench 4 is arranged in a forming position of a magnetic pole for development S1 turning to a main magnetic pole of the magnet roller 1. A magnet chip 5 formed of metal which is constituted of an axially anisotropic magnet of an Mn-Al-C type is fitted in the recessed trench 4. Since the magnet chip 5 is a metal magnet whose coercive force is at most 3 kOe, magnetizing magnetic field necessary for obtaining high magnetic flux density is reduced. As a result, locally high magnetic flux density can be realized in a main electrode while evading increase of size and electric power of magnetizing equipment.

Abstract: PURPOSE: To remove carbon films at the corners of a reaction chamber or in the upper part of a shower and in the lower part of a susceptor or in an exhausting part as well as in the side wall part of the reaction chamber by removing the carbon films accumulating in the reaction chamber through film formation by using a gas for oxidizing reaction. CONSTITUTION: In a cleaning step after carbon film formation, a pressure in a reaction chamber 1 is set to normal pressure and the inside of the chamber 1 is heated at about 100 deg.C by a heater 3 prepared on the bottom of a susceptor 2, then an O3 gas is introduced into the chamber 1 to oxidize the carbon films. When the O3 gas spreads sufficiently in the chamber 1, the carbon films are oxidized thereby and are turned into a gas such as SiO2 , etc., then they are exhausted. Therefore, the carbon films at the corners of the reaction chamber or in the upper part of a shower and in the lower part of the susceptor or in the exhausting part as well as in the side wall part of the reaction chamber are removed and almost all of carbon films are removed in the reaction chamber as a result.  Thus, any particle is prevented from generation during film formation thereafter, resulting in carbon films having an excellent film quality.
