Title: Optical encoder
Inventor: YAMANISHI TOSHIHIRO
IPC: G01D5/36
Filed: 1988-12-14
Abstract: PURPOSE:To offer an optical encoder which can cope with the detection of a position or a speed at a low cost and with high resolution by using a slit plate obtained by forming a V-shaped groove on one face of a plate-like body consisting of a transparent body having two parallel faces. CONSTITUTION:A slit plate 1 used for an optical encoder is a plate-like body consisting of a transparent body having faces 1a, 1b being parallel to each other, and on its face 1b, V-grooves 2a, 2b, 2c... having an inclined surface of an angle alpha are provided at equal intervals in parallel to each other. When light beams 3 irradiate, the surface vertically from the face 1a side, the light beams 3 irradiating a part in which there is no V-groove 2 transmits through the plate-like body 1 as it is. However, as for the light beams 3 irradiating a part of the V-groove 2, when the angle alpha is set in advance so that the V- groove surface makes an angle exceeding a critical angle against the light beam 3, the light beam 3 is brought to total reflection by this V-groove surface, and not emitted from the face 1b. That is, a section of V-grooves 2a, 2b, 2c... functions as a slit for cutting off the light beam 3.

Filed: 1991-11-29
Abstract: PURPOSE:To obtain the video signal processing method and device in which color noise with a high level is reduced without deterioration in the apparent resolution of a color signal by limiting an undesired vertical frequency band of the color signal. CONSTITUTION:An output of a luminance line memory 1 storing luminance data of a picture element in the vertical direction and color difference line memories 2a-2d recording chrominance data is inputted to an arithmetic operation means via shift registers 4a-4c. The arithmetic means extracts three consecutive picture elements of luminance data, uses a center picture element as a noted picture element and operated an arithmetic mean between upper and lower luminance data and chrominance data adjacent to the noted picture element in the vertical direction and the result is inputted to selection means 10a, 10b. An edge part in which a luminance change in the vertical direction is eminent is lightly filtered by a smoothing filter and a portion with less luminance change is filtered strongly by the smoothing filter. As a result, since the smoothing filter is applied to the chrominance data without incurring deterioration in the brightness of a picture, a high color noise reduction effect is obtained.

Filed: 1990-11-21
Abstract: PURPOSE:To prevent unnecessary heating and extension of print waiting time by providing a control means which raises the fixing temperature again to a set temperature according to a paper sheet feeding instruction during operation. CONSTITUTION:In waiting, temperature of a heating source 9 is controlled to be lowered below a set temperature, and in operating, this temperature is controlled to be raised again to the set temperature, and when this temperature is raised, it is carried out according to a paper sheet 2 feeding instruction. Therefore, even if data transformation process in a printer takes a long time due to transformation of a graphic figure and the like, when data from a host computer are transformed into image data and a print possible state appears, a control part of the printer gives the paper feeding instruction to the printer. By this paper feeding instruction, fixing temperature of the heating source 9 can be raised to the set temperature within the time from starting of the paper feeding until the paper sheet 2 reaches the heating source 9. Accordingly, unnecessary heating and extension of the print waiting time can be prevented.

Title: Multi-wired probe
Inventor: TANI KENICHIRO
IPC: G01R1/073
Filed: 1993-11-24
Abstract: PURPOSE:To enable a multi-wired probe to inspect even narrow-pitched circuits by fixing contact wires which are coated with insulating layers and have specific mum-order thicknesses and spring properties with resin-molded plates in an arranging state and forming the wires in U-shapes by removing the insulating layers from the wires at their contacting sections. CONSTITUTION:Contact wires 12 which are coated with insulating layers and have specific mum-order thicknesses and spring properties are fixed with resin-molded plates in an arranging state and the wires 12 are formed in U-shapes by removing the insulating layers from the wires at their contacting sections 14. A multi-wired probe 15 constituted in such a way can inspect circuits for continuity without hindrance even when the arranging pitches of the circuits is short. Since the sections 14 are formed in U-shapes, in addition, the sections 14 do not shave off circuits to be inspected even when the sections 14 are repeatedly brought into contact with the circuits and can be brought into contact under high contact pressures, resulting in stable contact and, at the same time, the buckling of the wires 12 at the contacting sections 12 can be prevented. Moreover, the wires do not short-circuit with another and no erroneous inspection occurs, since each wire 12 is coated with the insulating layer. Therefore, the inspection reliability and accuracy of the probe can be improved.

Abstract: PROBLEM TO BE SOLVED: To accurately instruct a driver to avoid deviation from the running lane by applying appropriate steering control torque without interfering the steering intended by the driver based on degree of the vehicle deviation from the running lane and the lateral acceleration. SOLUTION: A calculation means 4A for lateral deviation calculates the lateral deviation for the running position of a vehicle 1 from the reference position in the running lane. A calculation means 5 for control torque calculates the steering control torque obtained by the calculation means 4A for lateral deviation based on the lateral deviation. Then, the control torque obtained by a correction means 5A of the calculation means 5 based on the lateral deviation is further corrected based on the lateral acceleration detected by a lateral acceleration detecting means 31. Thus, a steering torque which may be easily overruled by the driver is determined based on the lateral deviation and the lateral acceleration. A control means 6 controls a steering actuator 21 for vehicle in the manner that the determined control torque is generated in the direction reducing the lateral deviation.
