Publication number: 20240153656Abstract: To provide an electrical penetration capable of being used in nuclear power plants which are designed assuming operation under conditions of the severe accident. An electrical penetration includes: a tubular sleeve member 10; two or more insulating seal members 20A and 20B arranged inside the sleeve member 10 so as to be spaced from each other; wiring members 60, 60 disposed along the longitudinal direction of the sleeve member 10 so as to extend across two insulating seal members of the two or more insulating seal members 20A and 20B; and outer seal members provided inside the sleeve member 10 and at the outermost portions of the two insulating seal members 20A and 20B. The wiring members 60, 60 are each covered with an insulator made of the same material as those of the outer seal members 21A and 21B.Type: ApplicationFiled: November 3, 2023Publication date: May 9, 2024Inventors: Shingo ITO, Yasuyuki GOTO, Yukiharu SATO, Teppei KUBOTA, Masayuki SHIMIZU, Susumu KUMAGAI, Atsushi WARIGAYA, Masamichi IDONUMA, Kenta KIMURA

Publication number: 20240096551Abstract: A method of manufacturing an inductor component includes preparing an insulating paste that is photosensitive and that includes a filler material composed of quartz, a glass material and a resin material, and a conductive paste, forming a first insulating layer by applying the insulating paste, and exposing the first insulating layer in a state where a first portion of the first insulating layer is shielded by a mask. The method further includes removing the first portion of the first insulating layer to form a groove at a position corresponding to the first portion, applying the conductive paste in the groove to form a coil conductor layer in the groove, and applying the insulating paste on the first insulating layer and the coil conductor layer to form a second insulating layer.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Applicant: Murata Manufacturing Co., Ltd.Inventors: Yoshiyuki OOTA, Tomohiro KIDO, Tomonori SAKATA, Masahiro KUBOTA, Kenta KONDO

Patent number: 11511370Abstract: A plurality of values measured are relatively compared to determine an optical axis deviation direction in which an optical axis of a measurement beam S deviates from a laser beam L. In performing laser welding in the optical axis deviation direction, an irradiation position of the measurement beam S is changed so that the irradiation position of the measurement beam S is moved to a rear side of the center of the optical axis of the laser beam L in the welding direction.Type: GrantFiled: October 9, 2020Date of Patent: November 29, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Michio Sakurai, Toshiyuki Mishima, Toru Sakai, Kenta Kubota, Kensuke Urata

Publication number: 20210031298Abstract: A plurality of values measured are relatively compared to determine an optical axis deviation direction in which an optical axis of a measurement beam deviates from a laser beam. Then, a first parallel plate and a second parallel plate are rotated to move an irradiation position of the measurement beam so that an optical axis of the measurement beam is substantially coaxial with an optical axis of the laser beam.Type: ApplicationFiled: October 9, 2020Publication date: February 4, 2021Inventors: Toru SAKAI, Michio SAKURAI, Toshiyuki MISHIMA, Kenta KUBOTA, Kensuke URATA

Publication number: 20210023655Abstract: Laser welding is performed while moving irradiation positions of a laser beam and a measurement beam in forward, rightward, rearward and leftward directions, and the penetration depth of a weld portion is measured during laser welding in each of the directions. Then, a direction in which a value smaller than a reference value is measured is determined to be an optical axis deviation direction, and a correction value is added to the values measured during the laser welding when the laser welding is performed in the optical axis deviation direction.Type: ApplicationFiled: October 9, 2020Publication date: January 28, 2021Inventors: Michio SAKURAI, Toru SAKAI, Kenta KUBOTA, Takashi URASHIMA, Daichi HIGASHI
