Title: Inrush current limit circuit
Inventor: FUJITA ATSUSHI
IPC: H02J1/00
Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To limit inrush current so as to be small when turning-on again with power supply stopped and operation stopped after long operation, by connecting DC voltage obtained by rectifying AC voltage through another rectifier to the input end of a voltage regulator, and connecting a capacitor having smaller capacity than the smoothing capacitor of a main rectifier. SOLUTION: Diodes 12, 13 (forward direction) are connected to the output side (AC side) of a noise filter 1, and a capacitor 14 having smaller capacity than the smoothing capacitor of a main rectifier is connected to the input side of a voltage regulator 9. If continuous operation is conducted and the AC side is opened and stopped under such a condition as a thermistor 3 is thermally saturated and its resistance value decreases, the power supply of the voltage regulator 9 for supplying power to a control circuit 8 is stopped on AC side, therefore, the voltage of the capacitor 14 with small capacity becomes zero in a short time, and the control circuit 8 and an excitation control circuit 6 stop.  Therefore, the charge of the smoothing capacitor 4 is discharged through a discharging resistor 5 in a long time, thus it is possible to reduce the inrush current at the time of turning-on again substantially.

Filed: 1989-01-20
Abstract: PURPOSE:To obtain a high quality picture by generating a correcting signal to correct an output signal corresponding to a dark current from output signals and correcting a read picture signal with the correcting signal. CONSTITUTION:In an arithmetic circuit 46 of a signal correcting circuit 20, a correcting signal Va is calculated based on a picture signal V0, and the signal Va is stored in a memory 48.

Picture information Vi photoelectrically converted by a CCD image sensor 18 is introduced to the adder 40 of the circuit 20. In this case, since the signal Vb is introduced to the adder 40, a picture signal Vi' to be introduced to an offset/gain adjustment circuit 42 becomes a signal to hold only picture information from which the dispersion of output voltage caused by the dark current is removed. Consequently, for output of the circuit 20, the corrected high quality signal V0 is outputted.
