    摘要： 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.

    摘要： An eddy current testing device which confirms that a change in characteristics of a target object is detected regardless of the magnitude of the change and specifying the position of a portion from which the change is detected. The device uses an eddy current probe to inspect a bent portion of a metal body, and has an inspection controller and a display unit. The inspection controller calculates a phase angle of a signal detected by the eddy current probe and generates flaw identification image data that indicates an area (or an area of the signal detected and determined to correspond to a flaw signal, based on the phase angle of the detected signal) of a flaw signal in coordinates in which the position of the portion of the target object is plotted along a coordinate axis. The display unit displays the flaw identification image data.

    摘要： An eddy current flaw detection sensor is provided which can detect a circumferential crack occurring at the deformed portion or peripheral portion thereof of a heat transfer tube with a high degree of sensitivity. Two excitation coils 1a, 1b cause eddy current B to flow in the axial direction of a tubular test object 31. A detection coil 2 disposed between the excitation coils 1a, 1b detects bypass eddy current D which flows in the circumferential direction of the test object 31 while bypassing a circumferential crack E. For this purpose, the coil axes of the excitation coils 1a, 1b are directed to the radial direction of the cylindrical protection member 3 and the coil axis of the detection coil 2 is directed to the axial direction of the protection member 3.

    摘要： An electrophotographing method using a corona charging device having areas with and without a grid. Prior to at least a second exposure step, a charging step is effected using both areas relative to the grid. A voltage applied to the grid in the second charging is lower than that in the first charging, and lower than a potential of a non-image region of the photosensitive body.
