Title: Optical processing device
Inventor: YONESHIMA KUNIHIRO
IPC: F24F13/02
Filed: 1989-03-31
Abstract: PURPOSE:To stabilize the light emission from a lamp so as to achieve an efficient optical processing by providing the lamp cooling air discharge line with a damper and an air flow pressure sensor, and controlling the damper-regulated air volume according to the signal from the air-flow pressure sensor. CONSTITUTION:The air flow rate through ducts 4 and 9 is not constant as it is affected by the air flow rate through the main duct 10, and such air flow rate fluctuation is detected by an air flow pressure sensor 13. A damper 14 is suitably moved by a DC motor 15 according to the signal from a controller 17 to control the damper angle so as to regulate the flow rate of discharge air through the duct 9. Therefore, the air flow pressure sensor 13 can detect the air flow pressure generated by the finally controlled air flow through the duct 4, and the detected signal is fed back to the controller 17 to suitably control the angle of damper 14 by means of the DC motor 15 so that the air flow rate through the duct 4 may be optimized for the lamp input.

In this way, by increasing the number of layers for constituting the layer of the photoreceptible layer 1000, an interferential effect of an irradiated light can be prevented. An interference fringe generated in minute part does not appear on a picture because the size of the minute part is smaller than the irradiated light spot diameter, namely, smaller than a resolution limit. In this way, the interference fringe is prevented, and this member can be used for laser light, etc.
