Title: Polishing method
Inventor: KAWADA KOICHI
IPC: B24B37/00
Filed: 1986-11-19
Abstract: PURPOSE:To aim at highly efficient and highly accurate machining for a high- hardness material, by irradiating a work machining surface being opposed to a polisher with a beam of light out of a light source, while accelerating photochemical, thermal reactions in a working fluid to be fed to abrasive grains and the work surface, and polishing it. CONSTITUTION:A workpiece 1 is attached to a jig 2 and rotated. A polisher 3 consists of an optically transparent material, and it is made freely rotatable to a ring 5 via a ball 4. Abrasive grains 7 and a working fluid 8 are interposed between the polisher 3, where pressurizing force is added, and a work surface 6 of the workpiece 1, and the work surface 6 is polished as being rotated. The work surface 6 is irradiated with a beam of light run past the transparent polisher 3 from a light source 9, whereby a reaction of the working fluid 8 is photochemically accelerated. And, temperature in a work local part along goes up due to absorption of the light and thereby a chemical reaction is accelerated, but a temperature rise is limited to the local part, so that thermal deformation due to the temperature rise in the workpiece 1 is minimized.

Inventor: FUEKI YUJI
IPC: B66F7/24
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To surely recognize whether an automatic operation of a jack is possible or not. SOLUTION: This jack operation control device 40 has a jack operating device 9 performing a manual operation for an outrigger jack, a mode changeover switch 41 for switching either one mode of a manual mode by the jack operating device 9 or an automatic mode for automatically controlling the operation of the outrigger jack, a car body inclination sensor 43 for detecting an inclined angle of a car body, a controller 45 and an automatic operation confirmation lamp 13. By a comparison and decision circuit 51 provided on the controller 45, the inclined angle of the car body is determined to be over an allowable inclined angle.  When the automatic mode is selected by the mode changeover switch 41, an operation selection circuit 55 regulates the selection of the automatic mode, the operation is switched to the manual operation by the jack operating device 9, and an operation control circuit 53 notifies a worker than an automatic operation of the outrigger jack can not be performed by turning off the automatic operation confirmation lamp 13.

Title: Signal transmission line of semiconductor ic
Inventor: YASUDA YOJI
IPC: G11C11/401
Filed: 1984-12-28
Abstract: PURPOSE:To speed up signal transmission of the titled device by reducing the parasitic capacitance of signal wirings, by a method wherein signal wirings are arranged into adjacent wirings with required wiring gaps and steps. CONSTITUTION:Metallic wirings 12, 13 of the first layer and a signal wiring 14 as the metallic wiring of the second layer are formed on a substrate 11 via insulation film. The wirings 12, 13 are provided in parallel with the wiring 14 by having a step. The signal wiring 14 is formed while keeping the horizontal distances (x) between itself and the adjacent wirings 12, 13 equal to the wiring width (d) of the signal wiring 14 or greater than this. Since this construction of the signal wiring line enlarges the gap between the wiring 14 and the substrate 11, the to-substrate capacitance C1' reduces. Since the wiring 14 and the adjacent wirings 12, 13 have steps in the longitudinal direction, the wiring capacitance C2' reduces, and the parasitic capacitance C1'+C2' largely reduces.

Title: Heterodyne light and time area reflectiometer
Inventor: MANFURETSUDO FUKUSU
IPC: G02B6/00
Filed: 1988-11-04
Abstract: PURPOSE: To reduce the light system loss of a reflection factor meter by superposing signals by a passive coupler. CONSTITUTION: An acoustic wave can pass in the direction of an arrow 2 through an acoustic optical modulator AOM 1. Light beams are guided through the AOM 1 via single-mode wave guides 3-6 and a lens that constitute a port. Then, when the AOM 1 is energized by a pulse mode, a wave guide to be tested by a light frequency being modulated by an acoustic frequency has the AOM 1 for deflecting transmission beams from a laser. When the AOM is not energized, a local oscillator beam LO that is constituted of laser beams that cross the AOM 1 is superposed. In this manner, when the superposition is achieved by the passive coupler, especially a fiber coupler 10, a light system loss can be reduced.

Title: Composite signal separating circuit
Inventor: YASUKI SEIJIROU
IPC: H04N9/78
Filed: 1986-11-21
Abstract: PURPOSE:To realize a noise reducing function by subtracting the output differential component of first and second separating means from the output of the first separating means when the action of the image is small and when the action of the image is large, separating a usual composite television signal without executing the subtracting processing. CONSTITUTION:Respective non-linear circuits 39-41, when an input signal is smaller than a prescribed value, making the input signal epsilon K-fold and output it, and when the input signal epsilon is larger than the prescribed value, they have the characteristic not to generate an output. For this reason, when the differential component between low pass luminance signals YOL and Y2L outputted from an adder circuit 32 is small, in short, an image is a still-picture or a moving image close to it, the output Y1L of an adder circuit 31 goes to Y1L=Y0L-K (Y0L-Y2L). When the differential component between high pass luminance signals Y0H and Y2H outputted from an adder circuit 36 is small, the output Y1H of an adder circuit 35 goes to Y1H=Y0H-K(Y0H-Y2H). Thus, the noise reducing function is realized, the constitution can be simplified and the picture quality deterioration does not occur.
