Title: Optical power meter
Inventor: KAWASAKI HIROYUKI
IPC: G01J1/42
Filed: 1989-07-22
Abstract: PURPOSE:To correct the error between ranges and to make it possible to perform accurate measurement in any range by switching the amplitude in correspondence with the output of an optoelectronic transducer element to which light is inputted. CONSTITUTION:The output signal from a photodiode 1 is amplified in an amplifier 2 and converted into a digital signal in an A/D converter 3. Then, the digital signal is sent into an operating and controlling circuit 4 which is composed of a microprocessor and the like. The signal undergoes correcting operation. Thereafter, the signal is outputted to a display device 5. The amplitude of the amplifier 2 is switched by switching the value of a feedback resistor based on a range switching signal outputted from the operating and controlling circuit 4 in response to the output of the A/D converter 3. The input range of the A/D converter 3 can be fully utilized by switching the amplitude of the amplifier 2 in response to the magnitude of the input signal, i.e. the intensity of light to be measured in this way. Thus the resolution of the power of the light to be measured i enhanced. The error between the ranges is corrected in this way, and the correct measurement can be performed in any range.

Filed: 1986-08-18
Abstract: PURPOSE:To remove the generation of a ghost image or the influence of history and to form a stable image by executing uniform exposure based upon light beams prior to a primary latent image forming process. CONSTITUTION:When a secondary electric charger 6 discharges AC or negative corona to the charged surface of a uniformly charged photosensitive body, and an image exposing device 7 makes the image exposure 1 incident through an exposure slit to form a primary latent image consisting of charge density corresponding to the intensity of color component beams transmitted through respective filters on an interface between an insulating layer 4 and a photoconductive layer 3. Then blue light LB is made uniformly incident upon a primary latent image forming surface by a uniform exposure device 8B, and an electrostatic latent image formed by the uniform exposure of blue light is developed by a developing device 9Y storing yellow toner for frictionally charging the latent image with negative charge. When corona discharge similar to that of the secondary charger 6 is applied to the surface of the photosensitive body 1 by a smoothing charger 10Y, the surface potential is smoothed to a potential level generating no toner adhesion. Said operation is repeated to form a full color image based upon the composition of yellow, magenta and cyan toner images on the photosensitive body.
