Patent JP-H063330-A (JP)
Title: Magnetizing device for magnetic particle inspection
Inventor: YOSHIDA MITSUO
IPC: H01F13/00
Filed: 1992-06-23
Abstract: PURPOSE:To suppress the excessive heat generation of an interpole magnetizing coil so that the title device can continuously perform sensitive measurement for a long time by providing a repulsing coil which generates magnetic fluxes in the direction opposite to that of leakage magnetic fluxes between two magnetic poles of the interpole magnetizing coil between the two magnetic poles. CONSTITUTION:A repulsing coil 10 is provided between two magnetic poles 2A and 2B of an interpole magnetizing coil 2. The coil 10 is constituted by connecting windings 2a and 2b in series to each other in the opposite directions so that the direction of magnetic fluxes 11 generated by the coil 10 can become opposite to the direction of leakage magnetic fluxes 9 between the magnetic poles 2A and 2B of the coil 2. Therefore, the heat generation caused by the interlinkage between the magnetic fluxes 9 and coils 2a and 2b can be prevented by reducing the amount of magnetic fluxes 9 between the poles 2a and 2B by using the magnetic fluxes 11 generated by the coil 10. In addition, since the reduced amount of the magnetic fluxes 9 is added to magnetic fluxes 8 which magnetize the upper side face 2 of a bar steel material 1, both side faces of the material 1 can be inspected for flaws with high sensitivity.

Abstract: PROBLEM TO BE SOLVED: To improve performance by forming a wall material mainly of a building raw material in which an inorganic adhesive, cement and water are added to and mixed with natural zeolite. SOLUTION: A building wall material 1 is formed by lining the reverse of a rectangular wall material body 2 of a prescribed thickness with a heat insulating material 3.

Title: Optical disk
Inventor: UENO ICHIRO
IPC: G11B7/24091
Filed: 1991-06-10
Abstract: PURPOSE:To obtain a high density recording disk by setting the change amount of unevenness corresponding to the height between the surface of a guide groove part and the surface of a non-guide groove part, and to an information signal to a prescribed value. CONSTITUTION:The optical disk is formed in such a way that a spiral groove or a concentric guide groove is provided on a substrate 1. The guide groove part G and the non-guide groove part L which are sequentially and alternately arranged in the direction of a diameter are used as recording areas. The information signal is recorded in the recording areas by the unevenness change corresponding to the information signal. The height between the surface of the guide groove part G and the surface of the non-guide groove part L is set to be less than 1/8 of the wavelength of reproduction light used for the reproduction of the information signal, and a numerical value obtained by multiplying the numerical value of the change amount of unevenness for recording the information signal by the refraction index of a constitution material in the part is set to be actually equal to 1/4 of the wavelength of reproduction light. Thus, the recording content of the information signal and a tracking error signal can satisfactorily be reproduced, and recording density can be made high.

Abstract: PURPOSE:To prevent that a noise generated by a switching operation in a digital circuit part from affecting an analog circuit part via a semiconductor substrate of a first conductivity type by a method wherein the central part of a semiconductor region of the first conductivity type is isolated electrically from the substrate. CONSTITUTION:A p-type well and an n-type well are formed in a p-type silicon substrate 100; the p-type well is constituted of a central part 102a and a peripheral part 102b. The part 102a is isolated from the part 102b and the substrate 100 by n-type semiconductor layers 103, 104; it is formed in either a digital circuit part or an analog circuit part.

Title: Image pick-up device for inspection scratch on cylindrical surface
Inventor: TAKANO TAKETOSHI
IPC: G01N21/88
Filed: 1995-06-30
Abstract: PURPOSE: To make image processing advantageous and to achieve an automatic inspection by illuminating a cylindrical inspection target with a line-shaped light source along the longitudinal direction of the target and picking up a two-dimensional development image of the entire periphery surface by rotating the inspection target. CONSTITUTION: The image of a specific visual field out of the surface of a rubber roller 4 irradiated by a light source 2 is picked up by a line camera 5. The visual field is along the longitudinal direction of the rubber roller 4 and the light source 2 is also along the longitudinal direction of the rubber roller, thus achieving a uniform lighting. The rubber roller 4 is rotated at a specific anglar velocity around a shaft, the two-dimensional image of the camera 5 is successively read for the rotation, and the image is edited into the two-dimensional development image on the entire- circumferential surface of the rubber roller 4. The complete reflection from the sound part of the rubber roller 4 goes in a direction differing from that of the camera 5, thus obtaining an image with intermediate gradation.  However, since the complete reflection from a scratched part 10 goes to the camera 5, halation occurs by that amount, thus obtaining an image with saturated gradation or an image close to it.

IPC: F02M55/00
Filed: 1987-07-01
Abstract: PURPOSE:To make it possible to supply fuel to an engine in proper injection rate and injection timing to an engine speed within a wide range by providing a control valve for continuously controlling an area of a fuel return passage to be smaller as the engine speed becomes higher. CONSTITUTION:In a fuel pressure control valve 7 mounted in a return passage 3, a value of current flowing to a solenoid 15 is set by an ECU 16 to be smaller as an engine speed becomes higher. With the above setting, the closed degree of an inflow port 8, which is closed by an outer peripheral surface of a large diameter part 11b on the fixed core 14 side of a plunger 11, becomes larger so that an area of the return passage 3 becomes smaller. Thus, the fuel quantity returned from a fuel injection valve 1 to a fuel 4 is controlled to be smaller so that the fuel pressure is controlled to be lager. Therefore, it is possible to supply fuel to an engine in proper injection rate and injection timing to an engine speed within a wide range.
