Title: Exposure device of electrophotographic apparatus
Inventor: NEMOTO SHIGEO
IPC: B41J2/45
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To restrain the occurrence of needless printing caused through the variation of light emitting intensity and unnecessary sensitivity in a photosensitive drum at a low temperature by monitoring the temperature of a semiconductor laser and controlling a bias driving current in accordance with temperature. SOLUTION: The bias current Ic flowed from a transistor Tr2 to a semiconductor laser 101, when the resistance value of a thermistor 107 is NTC1, is decided by Ic=(R1/R2)×Iref=(R1/R2)×(Vcc-Vbe)/(R1+R4+NTC1). Herein, the thermistor 107 shows negative characteristics, so that the resistance value lowers according to the increase of temperature, and the higher the temperature is in the thermistor 107, the larger the bias current Ic becomes, as a result, it comes to be small as the temperature is low. Namely, by setting the temperature-resistance characteristics of the thermistor 107 to the temperature characteristics of the semiconductor laser 101, a transition width to a driving current to obtain the intensity of an arbitrary laser beam from the bias current can be rendered uniform not depending on temperature.

Title: Method of starting static scherbius device
Inventor: KAMIMURA TAKESHI
IPC: H02P1/28
Filed: 1979-03-07
Abstract: PURPOSE:To make a starting resistor and a switch unnecessary by a method wherein a diode used as a forward converter is replaced with a thyristor and at the same time a phase is controlled by a phase controller in response to the actual value of the speed of an induction motor. CONSTITUTION:When a power supply side switch is closed, an induction motor 30 is energized and started. Upon receiving of an output signal from a speed detector  42, a phase controller 46 applies to forward converter 34 a firing pulse that makes  the control lag angle alpha of a forward converter 34 large when the rotational speed of  the induction motor 30 is low, and a firing pulse that makes the control lag angle  small when the rotational speed rises. The output of the forward converter 34 is  regenerated in the power supply via a DC reactor 36, a reverse converter 38, which  is controlled by a speed control unit 44, and an inverter transformer 40. When the rotational speed of the induction motor 30 enters the Scherbius region, a firing pulse that makes the control lag angle alpha zero is fed from the phase controller 46 to the forward converter 34.
