Title: Drive circuit for deuterium lamp and uv-ray absorption detector
Inventor: TANAKA HIROSHI
IPC: H05B41/00
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To suppress fluctuation in the quantity of light of a deuterium lamp due to fluctuation of commercial power supply voltage significantly along with temperature drift. SOLUTION: Power is fed from a heater power supply section 4 to the cathode heater of a deuterium lamp 1 and when electrons are emitted sufficiently from the cathode, the charging voltage of a capacitor C at a trigger power supply section 2 is applied, as a trigger voltage, to the anode of deuterium lamp 1. A transition is made from initial discharge to main discharge in the deuterium lamp 1 and a constant current is fed from the constant power supply 9 at a main power supply section 3 to the deuterium lamp 1. Since the output voltage from a switching constant voltage power supply 8 is invariant even if the voltage of a commercial power supply 5 fluctuates, output current from the constant power supply 9 is also invariant and the quantity of light of deuterium lamp 1 is kept at a constant level.

Abstract: PURPOSE: To make back feed of paper easy and sure as well by increasing or decreasing the spacing between two sets of paper guide plates by crank mechanisms, etc. thereby adjusting the distance between the folding paper near transfer region and the surface of photoconductor drum.  
     CONSTITUTION: When moving members 20, 20' are moved by the crank pins 23, 23' of the crank arms 19, 19' which are driven by motors 13, 13', moving fittings 15, 15' move cooperatively. This causes the moving members 21, 22, 21', 22' which support the pins 17, 18, 17', 18' of the movable guides 11, 12 supported to a stationary shaft 16 to move, by which the spacing of the members 11, 12 is adjusted. Hence, if this spacing is narrowed, the distance between the paper guided by the members 11, 12 and the surface of a photoconductor drum 8 becomes smaller and images are transferred onto the paper having folds. If the spacing is widened, the distance between the paper and transfer region expands and the paper having folds may be readily and surely back-fed without increasing load owing to lack of interference members such as leaf springs.
