Patent number: 11922964Abstract: Sound source enhancement technology is provided that is capable of improving sound source enhancement capabilities in accordance with settings of usage and applications. A PSD optimization device includes a PSD updating unit that takes a target sound PSD input value {circumflex over (?)}?S(?, ?), an interference noise PSD input value {circumflex over (?)}?IN(?, ?), and a background noise PSD input value {circumflex over (?)}?BN(?, ?) as input, and generates a target sound PSD output value ?S(?, ?), an interference noise PSD output value {circumflex over (?)}?IN(?, ?), and a background noise PSD output value {circumflex over (?)}?BN(?, ?), by solving an optimization problem for a cost function relating to a variable uS representing a target sound PSD, a variable uIN representing an interference noise PSD, and a variable uBN representing a background noise PSD.Type: GrantFiled: August 8, 2019Date of Patent: March 5, 2024Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Hironobu Chiba, Kenta Niwa, Noboru Harada

Patent number: 6058153Abstract: A preventive maintenance apparatus for structural members inside a nuclear reactor pressure vessel includes a ring-shaped guide rail having a plurality of lugs which is placed on an upper flange of a core shroud provided inside a reactor pressure vessel. At least some of lugs separately engage with a plurality of guide rods provided on an inner surface of the reactor pressure vessel. A turntable is rotated on the guide rail. A first discharging nozzle moving apparatus placed on the turntable moves a first discharging nozzle for adding compressive remaining stress to an outer surface of the core shroud in a radial direction of the core shroud and in an axial direction of the core shroud. A second discharging nozzle moving apparatus placed on the turntable moves a second discharging nozzle for adding compressive remaining stress to an inner surface of the core shroud in a radial direction of the core shroud and in an axial direction of the core shroud.Type: GrantFiled: February 20, 1998Date of Patent: May 2, 2000Assignees: Hitachi, Ltd., Babcock-Hitachi Kabushiki KaishaInventors: Koichi Kurosawa, Eisaku Hayashi, Sadato Shimizu, Minoru Ootaka, Fujio Yoshikubo, Ren Morinaka, Masayuki Nishino, Noboru Chiba, Kunio Enomoto, Kazunori Sato

Patent number: 5749384Abstract: An apparatus preventive maintenance having a driving mechanism capable of driving a jet nozzle 24 to cause it to travel upward-and-downward, to rotate and to swing is settled on the top of a housing in the bottom portion of a reactor pressure vessel and on a hole for a fuel support piece, water pumped by a high pressure pump is spouted from a jet nozzle, and cavitation bubbles generated during the spouting are supplied to the positions to be treated for preventive maintenance, such as housings in the bottom portion of the reactor pressure vessel. Therewith, the residual tensile stress in the position to be treated is improved in a releasing direction by the energy generated by the collapsing of the cavitation bubbles.Type: GrantFiled: March 24, 1995Date of Patent: May 12, 1998Assignees: Hitachi, Ltd., Babcock-Hitachi Kabushiki Kaisha, Hitachi Nuclear Engineering Co., Ltd., Hitachi Kiso Co., Ltd.Inventors: Eisaku Hayashi, Koichi Kurosawa, Fujio Yoshikubo, Hideyasu Furukawa, Ren Morinaka, Kunio Enomoto, Masahiro Otaka, Noboru Chiba, Kazunori Sato
