Title: Optical system for range finding
Inventor: CHO MICHIO
IPC: G02B7/32
Filed: 1985-08-27
Abstract: PURPOSE:To control so as to output an optimum photoelectric signal within the infinite range from very close distance by providing as well a diaphragm plate on at least either projecting lens or photodetecting lens and by performing the adjustment of the light quantity by limiting one part of the irradiating luminous flux at close distance side. CONSTITUTION:The light from the light emitting diode 1 emitting a near infrared ray is condensed by a projecting lens 2, propagated linearly according to an optical axis 3 and irradiated on a material body 6 as a spot light 5. The spot light 5 is reflected with diffusion on the surface of the body 6 and one part thereof is made incident on a photodetecting lens 8 according to optical axis 7. A line sensor 10 is arranged so that the longitudinal direction is allowed to coincide with the base line length direction at the rear part of the photodetecting lens arranged apart from the projecting lens 2 and base line length lambda, then. The optical axis 7 is inclined largely for an optical axis 11 when the body 6 is located at very close distance and the inclination of the optical axis 7 becomes smaller as the body 6 becomes at remote distance. And the luminous flux converged by the lens 8 is focused on the different position on the sensor 10 corresponding to the body distance and the sensor 10 outputs the focused position thereof as electrical signal, so by utilizing it, the distance upto the body 6 can be measured.

Title: Motor-driven rear wheel steering device
Inventor: SANO SEIJI
IPC: B62D5/04
Filed: 1992-07-14
Abstract: PURPOSE:To provide a great speed reduction ratio with a little movement amount of output shaft i.e., with a narrow space by making different the number of teeth of a driving gear from a driven gear to cause relative rotation between an input shaft and an output shaft. CONSTITUTION:When an input shaft 11 is rotated by the operation of an electric motor 30, a driving screw 11a and a driving gear 11b are rotated to transmit the rotation to a driven gear 12b so that an output shaft 12 and a driven screw 12d are rotated. By setting the number of teeth of the driving gear 11b to be A=40 and the number of teeth of the driven gear 12b to be C=39, relative rotation is caused between the input shaft 11 and the output shaft 12 so that the output shaft 12 is moved in the axial direction while being rotated to steer a rear wheel. The transfer amount S is expressed by (A-C)XD/C, and S=0.25 mm/rev, where A=40, C=39, and D is a pitch between the driving screw 11a and the driven screw 12a and 10mm/rev. Since the movement amount S is very small, a great speed reducing ratio is provided with a narrow space.

Title: Photosensitive drum for copying machine and production thereof
Inventor: HONMA MASAHITO
IPC: G03G5/05
Filed: 1989-07-21
Abstract: PURPOSE:To prevent the interference by a laser beam which is coherent light and to prevent the appearance of moire fringe patterns on printing by roughly forming the surface of the photosensitive body of a photosensitive drum by a solvent having high volatility for the photosensitive body. CONSTITUTION:A stock pipe 3 of the photosensitive drum is pulled up from coating liquid tank 1 in which a coating liquid 2 for a charge transfer layer is stored and is dried to form the charge transfer layer. The coating liquid 2 for the charge transfer layer applied on the surface of the stock pipe 3 is eventually immediately exposed to the outdoor air when the stock pipe 3 is pulled up from the coating liquid tank 1. Dichloromethane having high volatility is thus evaporated. The orange peel surface-like ruggedness is formed on the surface of the photosensitive body by the convection arising from the evaporated solvent and, therefore, the surface of the photosensitive drum can be roughly formed and the laser beam is irregularly reflected by the surface of the photosensitive body. The interference by the laser beam which is the coherent light is prevented in this way and the generating of the moire fringe patterns on the printing is prevented.

Inventor: SUZUKI SUSUMU
IPC: H04N9/78
Filed: 1989-07-20
Abstract: PURPOSE:To obtain a luminance signal (Y signal) and a chrominance signal with high quality by separating a video signal into a luminance signal and a chrominance signal with an inter-line comb-line filter circuit and an inter- frame comb-line filter circuit with use of the movement adaptive system. CONSTITUTION:A movement detection circuit 133 is a circuit detecting whether or not a picture element of a current processing object is moving and, e.g. the 1 frame luminance signal difference detection system is adopted. That is, the picture elements on the same position on a CRT screen between a current frame and a just preceding frame are compared, and when the difference exceeds a prescribed value, the presence of movement is decided and when not, the absence of movement is decided. When the result of detection by the movement detection circuit 133 represents the presence of movement, a changeover circuit 134 is thrown to the position of an inter-line comb-line filter circuit 131 and when the result of detection by the movement detection circuit 133 represents the absence of movement, the changeover circuit 134 is thrown to the position of an inter-frame comb-line filter circuit 132. Thus, a high luminance and chrominance signal of a picture element is obtained.

In the reproduction system, a read light from a light source LS is transmitted through the recording medium RM and converged by a lens LP and the image is formed to line image sensors ISr, ISg, ISb whose main scanning direction is the perpendicular direction and the light is subscanned in the direction X. The line image sensors ISr, ISg, ISb give red, green blue signals subject to photoelectric conversion to amplifiers 3, 2, 1 respectively. Thus, the signal processing for the sequential/simultaneous system conversion is easily implemented and the inexpensive recording and reproducing device is realized.
