Title: Air static pressure bearing having touch down bearing
Inventor: TAKEDA MINORU
IPC: F16C32/00
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To prevent a main shaft and a housing from directly interfering with each other to be damaged by retaining balls on the inner peripheral surface of a housing by a retainer to be functioned as a touch-down bearing, whereby even if the supply of air is stopped at the time of overload and power failure, the main shaft can be supported by the touch-down bearing. SOLUTION: Balls 3 are retained on the inner peripheral surface of a housing 2 by a retainer 4 to be functioned as a touch-down bearing. Normally, when air is supplied into a through hole 6 from an air supply passage 7, the air flows into an annular gap 5 from the axial direction and the peripheral direction of an outer cylinder to form a complete air film in the gap 5. Thus, a main shaft 1 is supported by air pressure to keep a fixed track resistance. When the air supply is stopped (the compressor is stopped) due to overload or power failure to the main shaft 1, the main shaft 1 is supported by the touch-down bearing. Thus, the outer periphery of the main shaft 1 and the inner periphery of the housing 2 will not directly interfere with each other so as to prevent damage.

Abstract: PURPOSE:To prevent an image from fogging or image dropout owing to the local deviation of a developer by detecting the distribution state of the amount of a developer in the axial direction of a developer holding member and conveying the developer in such a direction that the distribution is uniformed. CONSTITUTION:An electromagnetic latent image formed on a latent image carrier 1 is developed by a developing device 2 which is arranged opposite.

The means 7 use piezoelectric element, inductance varying elements, etc., and are turned ON in a circulation area A where the amount of the developer decreases and OFF in a stationary circulation area B and a circulation area C where the amount increases. The direction of local deviation of the developer is decided from the combination of outputs of the means 7 arranged on both sides of the device. A developer conveying means 8 is provided in parallel to the holding member 3 and a means 8 is brought under rotational control in such a direction that the distribution of the amount of the developer becomes uniform. Consequently, the local deviation of the developer is suppressed.
