Title: Image forming apparatus
Inventor: NOGUCHI BUNRO
IPC: G03G15/08
Filed: 2002-09-27
Abstract: <P>PROBLEM TO BE SOLVED: To prevent cleaning failure resulting from vibration of the surface of an image carrier caused by an AC component applied to an electrifying means and image failure caused by soil on an electrifying member and to minimize a decrease in print output speed, in an image forming apparatus using an intermediate transfer member having an AC electrification system capable of performing highly stable electrification by a simple structure.  <P>SOLUTION: In the image forming apparatus having the electrifying means which electrifies an image carrier by applying a bias in which AC and DC components overlap, a rotation period of the image carrier is extended during an image non-formation period separately from an ordinary image forming operation. The apparatus also includes a control means which switches a bias applied to the electrifying means to only the DC component. This makes it possible to obtain the image forming apparatus which is equipped with the AC electrification system capable of performing highly stable electrification by the simple structure and, at the same time, prevents cleaning failure and image failure caused by soil on the electrifying member.  <P>COPYRIGHT: (C)2004,JPO

Title: Compressor
Inventor: HIRASAWA TAKAHISA
IPC: F04B49/10
Filed: 2002-09-30
Abstract: <P>PROBLEM TO BE SOLVED: To perform highly reliable failure detection, by disposing a vibration detecting means for finding failure of a compressor at a portion not susceptible to receive influence of heat.  <P>SOLUTION: A piezoelectric element 22 as a vibration detecting means for detecting vibrations of a compressor body 50 is mounted in a power supply switch housing 33 supported by an air tank 1 on which the compressor main body 50 is placed, instead of being mounted to the compression body 50 itself that is susceptible to a high temperature. The piezoelectric element 22 detects the vibrations of the compressor body 50 through the air tank 1 or the like. Therefore, since the piezoelectric element 22 is not affected by heat, the piezoelectric element 22 can correctly detect the vibrations and thereby its reliability as a diagnostic device is enhanced.  <P>COPYRIGHT: (C)2004,JPO
