Patent number: 11579059Abstract: Whether an internal defect is present in an inspection target is readily judged. Provided is an inspection method for an inspection target that is a layered structure including an FRP material and/or a structure made of resin, the method including the steps of: tapping, with a tapping tool, an inspection target area on a surface of the inspection target; detecting, by an accelerometer mounted to the tapping tool, an acceleration signal corresponding to acceleration of the tapping tool due to reaction force against the tapping; recording waveform data about the detected acceleration signal; creating a contour map corresponding to the inspection target area, based on the recorded waveform data; displaying the contour map on a display unit; and judging whether an internal defect is present in the inspection target, based on the contour map displayed on the display unit.Type: GrantFiled: November 14, 2018Date of Patent: February 14, 2023Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Hisao Miyake, Yoshihiro Fujioka, Yoshiyuki Morii

Patent number: 7530757Abstract: A rotor coupling having insulated structure which can assuredly prevent galvanic corrosion of beating members, rotors and the like which is caused by shaft voltage, is provided in a shaft system that requires insulation. A generator is disposed in between a steam turbine and a gas turbine or a rotating machinery such as another steam turbine. The rotor coupling having insulated structure is employed in power generating equipment in which a generator is disposed in between a steam turbine and a gas turbine or a rotating machinery such as another steam turbine, a generator rotor and a rotating machinery rotor are connected, a first grounding electrode is provided to the steam turbine rotor, and a second grounding electrode is provided to the generator rotor, wherein both the rotors between the generator and the steam turbine are connected in an electrically insulated state.Type: GrantFiled: August 26, 2002Date of Patent: May 12, 2009Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Hideyuki Toda, Haruo Ishisaka, Yoshiyuki Morii
