Title: Roller carrying mechanism
Inventor: SUMI MAKOTO
IPC: B65H20/02
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a roller carrying mechanism, which can carry a medium at a constant speed, by forming a first roller, on which the medium abuts first, of a hard low-friction roller at a small friction and forming a second roller of a high-friction roller at a large friction. SOLUTION: A photosensitive material, which is pinched for carrying by a roller pair of a driven roller 21 and a driving roller 20 in a guide 24 direction, is guided in a driven roller 22 direction by a guide 24. A tip of the photosensitive material is made to abut on the driven roller 22, and slid for movement on the circumferential surface of the driven roller 22, and pinched by the roller pair of the driven roller 20 and the driving roller 22, and guided to a guide 25 direction. The photosensitive material is carried by the similar work of the guide 25, the driven roller 23 and the driving roller 20. The driven rollers 21, 22, 23 are made of resin and metal, and the driving roller 20 is made of rubber or the like, and even in the case where a tip part of the photosensitive material abuts on the driven rollers 22, 23 made of the hard material, elastic bounce for pushing the photosensitive material in the carrying direction for returning is not generated, and carrying resistance at the time of sliding the photosensitive material on the circumferential surface of the driven rollers 22, 23 at a low friction is small. Consequently, speed of the photosensitive material is maintained constant.

Title: Digital filter
Inventor: TAMAOKA MITSURU
IPC: H03H17/00
Filed: 1984-04-17
Abstract: PURPOSE:To form a signal smoothing digital filter which does not generate phase lag, by adding the effect of forecast besides the effect of signal averaging. CONSTITUTION:The digital filter is formed with a microprocessor 4. A means is provided where a variance in a certain period of data sampled at a certain period is approximated by a line. When data to be next sampled is given, this approximating means is used to forecast an average value. A technique where the variance is approximated by a linear formula in accordance with the method of least squares or a technique where the variance is approximated by a line in accordance with the change of moving average is used as this line approximating means. Thus, the signal amoothing digital filter which does not generate phase lag is formed.

Title: Optoelectric transducer
Inventor: SHIMIZU KATSUYA
IPC: H01L31/11
Filed: 1989-03-27
Abstract: PURPOSE:To raise the sensitivity of the device with respect to an optical input and assure bistable switching operation of a large current at a high speed under a DC bias by subjecting to Darlington connection a base modulation type bipolar transistor having a negative resistance characteristic and a phototransistor. CONSTITUTION:Stationary light is entered into a phototransistor section to energize a base 5a, a collector, and a gate 6 of a base modulation type bipolar transistor section into a back bias-state. Hereby, a high sensitivity large current output amplified by a Darlington connection between the phototransistor and the base modulation type bipolar transistor exhibits a negative resistance characteristic. Once a load is connected to an optoelectric transducer having such a negative resistance characteristic into which an optical input is then entered, a bistable output of a large current having a hysteresis at a high speed is yielded in a high sensitivity with respect to an optical input. Thus, bistable switching operation having a hysteresis with respect to an optical input is assured with two terminals, and hence high sensitivity and high output are yielded with a simple construction and without any circuit for later processing.

Abstract: PURPOSE:To form a high-quality image which is minutely controlled by changing two or more kinds of light emitting intensity in a time which is the light emitting pulse width of a semiconductor laser. CONSTITUTION:When multi-level image data is inputted, it is converted into the data on the light emitting intensity and light emitting time corresponding to the image data in a data conversion circuit 14 and outputted to a power control part 15 and a light emitting pulse width control part 16. Namely, in the case that the light emitting density in one dot changes, the data is assigned to the light emitting intensity and the light emitting time corresponding to the intensity, and the number of the data increases when the light emitting intensity in one dot changes. Thus, the shape and the size of a latent image per dot which is formed on a photosensitive body are minutely controlled by changing two or more kinds of light emitting intensity in the time which is the light emitting pulse width of the semiconductor laser, thereby accomplishing tone expression in the case of forming the image and minutely correcting the image.
