Title: Image forming device
Inventor: YOSHIDA MINORU
IPC: G03G21/10
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a distinct image even in the case of consecutive printing by controlling electric field between a non-patterning member and a photosensitive body so that the charge amount of developer may be smaller than that of normal developer electrostatic charging polarity. CONSTITUTION:By allowing the brush 2a of a non-patterning means 2 to contact with a developer image which remains at the time of transferring and an electrostatic latent image, non-patterning is electrostatically and mechanically performed. Then, a photosensitive drum 1 reaches a developing and cleaning position again but residual developer is nearly uniformly and thinly scattered, so that irregularity in exposure does not occur. Since proper developing bias is impressed on a developing roller 10, the developer newly adheres to an exposing part from the roller 10 and simultaneously the residual developer adhering to a non-image area is attracted to the roller 10 to be recovered. It is good that the electrostatic charging amount Q of the developer in a developing device and the average electrostatic charging amount QA of the developer adhering to an image carrier after the developer passes a developer image non-patterning member satisfy the relation of 0.5XQ<=QA<-1.0XQ in the case that Q is negative polarity and 0.5XQ>=QA>-1.0XQ in the case that Q is positive polarity.

Title: Method for controlling active filter
Inventor: KAMIMURA YOSHIAKI
IPC: H02M1/12
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To reduce damping resistance of an active filter by suppressing resonance phenomenon of impedance of a power system and a ripple absorbing high-frequency filter capacitor of the active filter, by detecting the voltage of the filter capacitor and adding the higher harmonic component of the detected voltage to a compensating current command value. SOLUTION: A controller 8 adds a load current detected by means of a current transformer 11 and a voltage of a high-frequency filter capacitor 9 detected by means of a transformer 12 to each other. Then a compensating current command computing circuit using three-phase/two-phase conversion calculates a compensating current command value, Ic=-Gn(s)×(-kVf+I1) (where, Gn(s), G(s), and Vf respectively represent a notch filter to a fundamental wave, a transfer function, and the voltage of the high frequency capacitor 9), by adding the K-fold value of the gain of the reverse code of the higher harmonic component of the voltage of the capacitor 9 to the conventional current command and outputs the command value. Therefore, the damping resistance of an active filter can be reduced and ripple currents can be absorbed by suppressing the resonance of the impedance of a power system and the capacitor 9.
