Filed: 1986-11-14
Abstract: PURPOSE:To prevent a temperature sensor from malfunctioning at the time of temperature detection by rotating a photosensitive drum at slower speed in copying stand-by mode than in copying operation so that the photosensitive drum is not heated locally by a fixing heater. CONSTITUTION:When the copying operation is performed, a signal E1 is inputted to a control means C and a motor M rotates the photosensitive drum 31 at the speed of 30 turns per minute. When a copying machine main body 11 finishes copying and afterward processes, a signal E2 is inputted to the control means C and the motor M rotates the photosensitive drum 31 at the speed of one turn per minute for a period until the next start of copying operation, i.e. in copying stand-by mode. Here, a heat source lamp H2 is provided on the left side of the photosensitive drum 31, so the temperature of the photosensitive drum 31 rises by its heat radiation, the rotation is maintained even in the copying stand-by mode, so the photosensitive drum 31 is never heated locally. The temperature sensor 3, therefore, detects the temperature of the photosensitive drum 31 without malfunctioning. An electric heater 11, on the other hand, holds the temperature of the photosensitive drum 31 at a specific value.

Abstract: PURPOSE:To achieve predictive integrity of a lightning arrester by predicting deterioration of the lightning arrester according to size and change of counted value which is obtained by performing light to electricity conversion of pulse light using a signal processing means. CONSTITUTION:A voltage which is proportional to leakage current of a lightning arrester is charged to a capacitor C1 of a charging circuit part 12, a thyristor TH of a switch circuit part 14 is turned on when this voltage reaches a voltage which is set by a zener diode ZD and resistors R1 and R2, electric charge of the capacitor C1 is discharged, and a light-emitting diode LED is illuminated. When leakage current of the lightning arrester reaches a specified level before deterioration, the light-emitting diode LED is illuminated once, thus enabling the thyristor TH to be turned on due to voltage drop caused by discharge of the capacitor C1, the capacitor C1 to be discharged due to leakage current again, and charging and discharging to be repeated. Emission frequency of this light emitting diode LED allows size of leakage current of the lightning rod to be known and degree of deterioration of the lightning arrester to be known, thus achieving preventive integrity of the lighting arrester.
