Title: Inverting amplifier circuit
Inventor: KOTOBUKI KOKURYO
IPC: H03F1/34
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To eliminate the influence of cross talk between a lead wire set between a refresh switch and the input side of an inverter circuit and an analog input voltage supply line by arranging the refresh switch at a position that is closer to the inverter circuit than the analog input voltage supply line. SOLUTION: A refresh switch SW1 is arranged at a position that is closer to an inverter circuit INV than an analog input voltage Ai supply line. A lead wire which is led from the SW1 to the input of the circuit INV does not cross the analog input voltage Ai supply line. As a result, the influence of the analog input voltage Ai is eliminated to a floating node of the input side of the circuit INV. In other words, the interaction is eliminated between the lead wire between the SW1 and the input of the circuit INV and the analog input voltage Ai supply line and also the interaction is eliminated between a refresh control signal CNT1 and the voltage Ai. Thus, the output accuracy is compensated.

Filed: 1990-04-27
Abstract: PURPOSE:To prevent the dispersion of picture quality from occurring by detecting that surface potential at the exposure part of a photosensitive body cannot be controlled to a target value caused by the secular fatigue of a laser diode LD and displaying that the exchange of the LD is demanded. CONSTITUTION:When potential difference from a subtracter 62 is detected, each current or voltage of the LD40 or an electrostatic charger 3 is adjusted and added to a current or voltage transformer 10 by a controlled variable set part 60 based on the potential difference. Then, in the case that it is judged by the set part 60 based on the secular fatigue of the LD 40 that the photosensitive body is not converged to the target value even when the current is adjusted, the display that the exchange of the LD40 is demanded is executed on a display part 9. Thus, since the secular fatigue of the LD40 is precisely grasped and the LD40 is exchanged based on it, the LD40 can be effectively and usefully used with time. Besides, the dispersion of the potential at the time of exchanging an LD unit is restrained and the stable picture quality is obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent trouble due to fluctuation of various timings in a machine body delivering a detection signal from a second laser light detection means to a synchronism detection signal selecting means while regulating the timing to be substantially equal to that of output from the laser light detection means. SOLUTION: A timing regulating section 21 regulates the timing of detection signal from a second laser light detection sensor 5 to be substantially equal to that of output from a first laser light detection sensor 4 before delivering an output to a synchronism detection signal selecting section 22. Consequently, even when a detection signal from the second laser light detection sensor 5 is employed as a synchronism detection signal, writing of image information to an effective image area on a photosensitive drum 2 can be started at an optimal timing using laser light. Since various timing can be set based on a detection signal from the second laser light detection sensor 5 at the control section 24 of machine body, trouble due to fluctuation of various timings in the machine body can be prevented.
