Patent number: 9464889Abstract: A method comprises a calibration curve creation step in which a calibration curve is created on the basis of hardened surface layer depth. A destructive test is performed on one of two samples in pairs, and propagation time of a first peak of a first wave of waveform of a signal outputted with the other in pairs in a non-destructive test is determined, the samples in pairs being prepared such that carburization depth varies gradually from pair to pair. A waveform of a signal outputted with a to-be-inspected piece is obtained. The propagation time of a first peak of a first wave of the waveform of the signal output with the to-be-inspected piece is obtained, and the hardened surface layer depth of the to-be-inspected piece is obtained using the calibration curve, on the basis of the propagation time obtained with the to-be-inspected sample.Type: GrantFiled: September 16, 2011Date of Patent: October 11, 2016Assignee: IHI CORPORATIONInventors: Arisa Yanagihara, Minoru Tagami, Kenichiro Watanabe, Yoshinori Ishida

Patent number: 5536704Abstract: A composite material comprising a bulky substrate of a Y-series 123 metal oxide crystal, and at least one layer provided on a surface of the substrate and formed of a crystal of a Y-series 123 metal oxide. The substrate may be produced by immersing a seed material in a liquid phase which comprises components constituting the metal oxide. The liquid phase contains a solid phase located at a position different from the position at which the seed material contacts the liquid phase. The solid phase provides the liquid phase with solutes which constitute the Y-series 123 metal oxide so that the solutes are transported to the position at which the seed material and the liquid phase contact, thereby permitting the Y-series 123 metal oxide to grow on the seed material as primary crystals and to obtain the bulky substrate. The layer of a Y-series 123 metal oxide may be formed on the substrate by a sputtering method, a vacuum deposition method, a laser abrasion method, a CVD method or a liquid phase epitaxy method.Type: GrantFiled: May 9, 1994Date of Patent: July 16, 1996Assignees: International Superconductivity Technology Center, Mitsubishi Cable Industries, Ltd., Kyocera Corporation, Japan Energy CorporationInventors: Yasuji Yamada, Minoru Tagami, Masaru Nakamura, Hideki Sakai, Koichi Uehara, Yuh Shiohara, Shoji Tanaka
