Patent number: 10809232Abstract: In one embodiment, a pipe inspecting apparatus includes a selection module configured to select first and second ultrasonic optical probes from a plurality of ultrasonic optical probes attached to a pipe. The apparatus further includes a power supplying module configured to supply power to an ultrasonic transducer of the first ultrasonic optical probe to input an ultrasonic wave from the ultrasonic transducer to the pipe and to supply the ultrasonic wave via the pipe to an optical fiber sensor of the second ultrasonic optical probe. The apparatus further includes a light detection module configured to detect laser light transmitted through the optical fiber sensor of the second ultrasonic optical probe.Type: GrantFiled: August 7, 2015Date of Patent: October 20, 2020Assignee: Kabushiki Kaisha ToshibaInventors: Keiichi Sasaki, Daisuke Asakura, Hiroaki Cho, Tetsuo Endoh, Shohei Matsumoto

Patent number: 10082035Abstract: An erosion resistant material has a continuous portion and discontinuous portions. The continuous portion has a continuous structure. The discontinuous portions are arranged inside the continuous portion to have a discontinuous structure. The discontinuous portions are formed of particles having an average particle diameter of 1 ?m or less. Further, the discontinuous portions are formed of a material having a surface hardness and a Young's modulus higher than those of the continuous portion.Type: GrantFiled: February 24, 2016Date of Patent: September 25, 2018Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Tetsushi Okamoto, Fumio Sawa, Takashi Harakawa, Kenichi Yamazaki, Hiroaki Cho, Naoki Shibukawa, Tadayuki Hashidate, Yoshihiro Hyodo, Akira Tanaka, Masamitsu Sakuma

Patent number: 9713839Abstract: In a continuous casting method for casting aluminum-deoxidized molten stainless steel 1 by using a continuous casting apparatus 100 in which a long nozzle 3 extending into a tundish 101 is provided at a ladle 2, the molten stainless steel 1 is poured into the tundish 101 through the long nozzle 3, while the spout 3a of the long nozzle 3 is being immersed in the molten stainless steel 1 that has been poured, and the molten stainless steel 1 in the tundish 101 is poured into a casting mold 105. A TD powder 5 is sprayed so that the powder covers the surface of the molten stainless steel 1 in the tundish 101, and nitrogen gas is supplied around the molten stainless steel 1. A calcium-containing material is added to the molten stainless steel 1 in a state other than a state of retention in the tundish 101.Type: GrantFiled: September 24, 2014Date of Patent: July 25, 2017Assignee: Nisshin Steel Co., Ltd.Inventors: Yuuki Honda, Hiroshi Morikawa, Hiroaki Cho, Noriaki Nukushina
