Title: Landing corrector of color television receiver
Inventor: SAWARA HIROSHI
IPC: H04N9/29
Filed: 1978-04-12
Abstract: PURPOSE: To make it possible to correct landing in any direction by storing the variation in the landing at the time of demagnetization in a certain direction and by accurately adjusting the landing correction on the basis of the obtained data.  
     CONSTITUTION: With the switch of a color television turned ON, earth magnetism detection circuit 1 starts operating immediately and its detection voltage is stored in analog memory 4. Magnetic eraser 2, on the other hand, also operates immediately to erase magnetism. To landing correction circuit 3, a voltage obtained by multiplying by -1/2 the earth magnetic detection voltage at the time of magnetic erasing stored in analog memory 4 and the earth magnetic detection voltage detected invariably are both inputted. As a result, the correction value lessens when it remains at the magnetic erasing time and increases when the direction of the television is opposite. This phenomenon is equivalent to the correction after the magnetic erasing at every time when the direction is changed. Namely, the correction of the color television in a moving body becomes accurate.

Title: Method, and device for inspecting surface defect and manufacture of sheet-shaped material
Inventor: NAKAJI SHINICHI
IPC: G01N21/89
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To inspect surface recessed or projecting defects accurately and speedily, by extinguishing light with an extinction material, radiating the light in specific incident angle range to a surface of an object to be inspected, and measuring its reflected light with light receiving part. SOLUTION: A light transmitting part 20 radiates light onto a surface region 60 of a sheet- shaped material 10, and a light receiving part 40 measures its reflected light. An extinction material 30 which distinguishes incident light in incident angle range α is placed between the light transmitting part 20 and the surface region 60. The extinction material 30 is positioned such that the equation, L1 tan α=W1 /2 is met, where L1 is distance between the material and the surface region 60 and W1 is material's width. The light receiving part 40 is positioned such that the equation, L2 tan β=W2 /2 is met, where L2 is distance between its light receiving surface 41 and the surface region 60 and W2 is width of the light receiving surface 41. Then, incident angle range α is greater than or equal to light receiving angle range β.  When there is a defect with gradient angle θk , reflected angle distribution is transferred in parallel by 2θk , and therefore setting α<θk allows the reflected light to face the light receiving part 40 and defects to be detected. Thus, when a defect surface has gradient more than a prescribed angle, signal strength provided by the light receiving part 40 is processed and surface defects are detected.

Title: Shut-off valve for railroad crossing gate
IPC: B61L29/04
Filed: 1992-02-28
Abstract: PURPOSE: To provide the shut-off valve of a rail-road crossing gate having excellent impact-resistance and self-recovering capability with a visco-elastic behavior whose elasticity is small for preventing any secondary disaster due to a shut-off valve impact accident in a railroad crossing. CONSTITUTION: This shut-off valve is provided with two plane plate members 10 extended to the longitudinal direction of a bar and a visco-elastic double coated adhesive tape 12 interposed between those plane plate members 10 like a layer. The plane plate member 10 itself has little bending due to its own weight while having flexibility against an outer force and self-recovering capability after folding. The visco-elastic double coated adhesive tape 12 is made of visco-elastic materials whose elasticity is relatively small, and closely adhered to each plane plate member 10 along almost the whole face of each boundary face of the plane plate member 10. When any outer force is impressed to the bar, the plane plate member 10 is elastically deformed.  At that time, the visco- elastic double coated adhesive tape 12 can prevent the stress concentration of each plane plate member 10 and absorb the elastic recovering force with the visco-elastic behavior characteristics.

Title: Power source device, electric equipment and copying machine
Inventor: ISHIHIRA RIYOUTA
IPC: G05F1/455
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To reduce the leakage and radiation of a higher harmonic component to a power source side by restricting the generation of the higher harmonic component. SOLUTION: A control circuit 1 turns on a TRIAC Tr1 and turns off the TRIAC Tr2 at the time of turning on the power source. Thus, A.C. is permitted to flow in a route adding a resistance load 3, a capacitor C1 and the TRIAC Tr1 from a commercial power source 2 and the capacitor C1 is charged. After that, when current flowing in Tr1 becomes equal to below the holding current of the TRIAC with the charging of C1, Tr1 is turned off. When Tr1 is turned off, the control circuit 1 turns on Tr2 and the charging current of C1 is permitted to flow in the route adding Tr1 and the resistance load 3. When current flowing in Tr2 becomes equal to below the holding current of the TRIAC with the discharging of C1, Tr2 is turned off. When Tr 2 is turned off, the control circuit 21 turns on Tr1.  The control circuit 1 turns on/off Tr1 and Tr2 by a frequency drastically higher than a commercial power source frequency and transmits power to the resistance load 3 so that the generation of the higher harmonic component is reduced by the improvement of a force rate.
