Publication number: 20170082676Abstract: The present invention provides a singularity locator that enables a singularity such as a fault to be located even in a near-end section. One embodiment of the present invention is a singularity locator (1) that locates a singularity by comparing a transmission wave with a reflected wave of the transmission wave reflected at the singularity at which impedance changes. The transmission wave is a frequency modulated continuous-wave (FMCW) with a continuously modulated frequency, and the singularity is located based on a difference in frequency between the transmission wave and the reflected wave.Type: ApplicationFiled: December 5, 2016Publication date: March 23, 2017Applicants: FUJIKURA LTD., ELECTRIC POWER DEVELOPMENT CO., LTD.Inventors: Yuji KUMAMOTO, Keishi SHIBAYAMA, Kazuo AMANO

Patent number: 5553106Abstract: Low temperature water in a low temperature water tank 12 installed outside a reactor pressure vessel 9 is pumped by a high pressure pump 15 and supplied through a conductor 17 under pressure. The supplied water is ejected, as a stream of cold water jet 8, from a nozzle 14 connected to the conductor 17 and introduced into the reactor pressure vessel 9 by a driving mechanism. The stream of cold water jet 8 ejected from the nozzle 14 is directed to impinge against a predetermined position of a core shroud 13 in reactor water 11 filled in the reactor pressure vessel 9 and being at temperature higher than the low temperature water. Then, while continuing to eject the cold water jet 8 from the nozzle 14, the nozzle 14 is moved away from the predetermined position, or the ejection of the cold water jet 8 from the nozzle 14 is stopped, allowing the predetermined position to be heated again with the temperature of the reactor water 11.Type: GrantFiled: June 14, 1995Date of Patent: September 3, 1996Assignees: Hitachi, Ltd., Babcock-Hitachi Kabushiki KaishaInventors: Kunio Enomoto, Masahiro Otaka, Kazuo Amano, Koichi Kurosawa, Eisaku Hayashi, Ren Morinaka, Shigeo Hattori, Kasunori Sato

Patent number: 5308162Abstract: A temperature abnormality detecting structure for a fluid pipe detects a temperature abnormality location by laying an optical fiber serving as a temperature detecting portion of a Ramam scattering optical fiber distribution type temperature sensor along a fluid pipe. The fluid pipe is divided into a plurality of sections in the longitudinal direction, independent optical fibers are laid along the fluid pipe in the respective sections. A portion of the optical fiber laid along one of the adjacent sections is superposed to be laid on a portion of the optical fiber laid along the other of the adjacent sections in the vicinity of each of the respective boundaries of the sections.Type: GrantFiled: February 10, 1993Date of Patent: May 3, 1994Assignee: Fujikura Ltd.Inventors: Kazuo Amano, Shotaro Yoshida

Patent number: 5178465Abstract: In an optical fiber laying structure for an electric power cable line trouble occurrence location detecting system for detecting a trouble occurrence location by laying an optical fiber along an electric power cable line, the portion of the optical fiber laid along the cable of one of the two adjacent sections is superposed on the portion of the optical fiber laid along the cable of the other sections in an area in the vicinity of the boundary of the electric power cable line. Thus, if a temperature rise occurs due to a trouble such as a ground-fault in the boundary area, the temperature peak position, i.e., the trouble occurrence location can be detected by the two different optical fibers. Therefore, the trouble occurrence location in the boundary area can be accurately detected.Type: GrantFiled: July 9, 1991Date of Patent: January 12, 1993Assignee: Fujikura Ltd.Inventors: Kazuo Amano, Shotaro Yoshida
