  • Patent number: 10020646
    Abstract: A busbar includes: an elongated busbar body which is composed of an electrically conductive material; and an insulating coating which covers the circumference of the busbar body. The cross section of the busbar body orthogonal to the longitudinal direction is substantially rectangular. The insulating coating is composed of a light curing resin which has an elongation percentage of not less than 50% after being cured and a Young's modulus of not more than 900 MPa. And the insulating coating is formed by applying the light curing resin onto the surface of the busbar body and then curing the applied light curing resin. The light curing resin has a viscosity of 10 to 1000 Pa·s at 25° C.

  • Patent number: 8339130
    Abstract: The surface length of a metal subject to be inspected is evaluated by detecting an eddy current without using a combination of a scale and visual or liquid penetrant inspection. An exciting coil and a detecting coil are scanned above the subject in a length direction. An eddy current detector measures an output voltage corresponding to scanning positions based on an output from the detecting coil. Based on an output voltage distribution curve indicating a distribution of output voltages corresponding to the scanning positions, position information is extracted corresponding to values which are within a differential voltage range and lower by 12 dB than a maximum value of the output voltages on the left and right sides of the distribution. A distance between the positions included in the extracted information is calculated to evaluate the length of a slit which is a defect present on the subject surface.

  • Patent number: 8228058
    Abstract: Disclosed is an eddy current flaw detection probe that is capable of pressing itself against an inspection target whose curvature varies. A flaw sensor is configured by fastening a plurality of coils to a flexible substrate that faces the surface of the inspection target. A first elastic body is positioned opposite the inspection target for the flaw sensor, is obtained by stacking two or more elastic plates, and has an elastic coefficient that varies in a longitudinal direction. A second elastic body is a porous body positioned between the flexible substrate and the first elastic body. A pressure section is employed to press the first elastic body toward the inspection target.
