Filed: 2002-03-11
Abstract: <P>PROBLEM TO BE SOLVED: To prevent a phenomenon wherein the rise time of a laser driving current is prolonged on account of the saturation of an output voltage of an operational amplifier, while an increase in cost is restrained.  <P>SOLUTION: In a case that an anode of a semiconductor laser is set as a ground potential and a cathode is set as a negative potential in order to prevent the saturation of an output voltage of the negative side of the operational amplifier, the absolute value of a negative power source voltage is made greater than that of a positive power source voltage in a range of the absolute maximum rating of the operational amplifier. In the case that the cathode of the semiconductor laser is set as a ground potential and the anode is set as a positive potential in order to prevent the saturation of an output voltage of the positive side of the operational amplifier, the absolute value of the positive power source voltage is made greater than that of the negative power source voltage in the range of the absolute maximum rating of the operational amplifier. As a result, an output voltage of the operational amplifier is prevented from saturation, so that an ideal rise time of the laser driving current can be obtained, and the laser driving current can be pulse-modulated at a high speed and a low cost.  <P>COPYRIGHT: (C)2003,JPO

Filed: 2002-03-12
Abstract: <P>PROBLEM TO BE SOLVED: To prevent the occurrence of a handling shimmy by suppressing the number of balance weights used for correcting the weight unbalance of a tire with wheel to the minimum.  <P>SOLUTION: The weight unbalance of the tire with wheel A obtained by fitting a tire T to a wheel W is measured and, when a dynamic unbalance of the tire A is smaller than a prescribed value, the static unbalance of the tire A is corrected by attaching a balance weight wi to the inner rim Ri of the wheel W. When the dynamic unbalance of the assembly A is the prescribed value or higher, the dynamic unbalance is corrected by respectively attaching balance weights wi and wo to the inner and outer rims Ri and Ro of the wheel W. Since the static unbalance which causes the handling shimmy can be corrected surely including the case where the dynamic unbalance which is equal to or higher than the prescribed value is corrected, the occurrence of the handling shimmy can be prevented surely. In addition, the appearance of the tire with wheel A is improved, because the balance weight wi attached to the inner rim Ri for correcting the static unbalance goes out of sight.  <P>COPYRIGHT: (C)2003,JPO

Title: Developing device and image forming apparatus
Inventor: ASAMI AKIRA
IPC: G03G21/14
Filed: 2002-03-20
Abstract: <P>PROBLEM TO BE SOLVED: To decrease soiling on a sleeve without exerting influence on developing ability.  <P>SOLUTION: Alternating electric field of higher frequency than the frequency of alternating electric field applied to a latent image forming area is formed in an inter-paper area on a photoreceptor drum. Thus, the adhesive force of toner adhering to the surface of a developing sleeve opposed to the inter-paper area is weakened when the inter-paper area exists at a developing position, whereby the soiling on the sleeve is decreased. The higher the frequency of the alternating electric field is made, the higher an effect to weaken the adhesive force of the toner to the surface of the developing sleeve becomes, which happens to deteriorate image quality. However, the alternating electric field of the high frequency is formed only in the inter-paper area, so that the developing ability is not adversely influenced.  <P>COPYRIGHT: (C)2004,JPO
