Title: Exposing device
Inventor: UCHIYAMA KAORU
IPC: G03B27/54
Filed: 1990-01-22
Abstract: PURPOSE:To miniaturize an exposing device by synchronously feeding a light transmission type original and a photosensitive material and performing slit- exposure to the photosensitive material. CONSTITUTION:The feeding speeds of the original 71 and the photosensitive material 26 are adjusted so that the material 26 may be fed faster than the original 71 by the amount of enlarging magnification at the time of exposing the photosensitive material. At this time, the original 71 and the material 26 are synchronously fed so that the slit-scanning starting end and the slit-scanning finishing end of the original 71 may coincide with the slit-exposure starting end and the slit-exposure finishing end of the material 26. Thus, a means for moving an optical system in the case of performing surface exposure is not necessitated and the exposing device can be miniaturized.

Title: Constant current power supply circuit
Inventor: SUZUKI KAZUYA
IPC: G05F1/56
Filed: 1987-01-20
Abstract: PURPOSE:To execute stable operation near a load opening point or an overvoltage starting point by providing the titled circuit with a control circuit for controlling a voltage detecting signal in response to the level of a current detecting signal outputted from a current detecting circuit when the current detecting signal is <=a set value, and suspending its control when the current detecting signal is reduced less than the set value. CONSTITUTION:When an output current is high and a detecting signal from the current detecting circuit 3 is high, current restricted by current flowing into the control circuit 13 is allowed to flow from a voltage detecting point 4x into an amplifier 11. When the output voltage of a main circuit 2 is boosted and a voltage detecting signal from a resistor 4b in a voltage detecting circuit 4 becomes equal to the reference voltage of a reference power supply 10 for an amplifier 11, a signal from the amplifier 11 is transmitted to the main circuit 2 to prevent the output voltage from being higher than an overvoltage set value, and when the impedance of a load 5 is increased furthermore, the output current is more reduced. Since voltage drop based upon a resistor 4a is reduced in accordance with the reduction of the output current, the output voltage is reduced and the signal voltage from the resistor 4b is kept at a value equal to the voltage of a reference power supply 17.
