Patent number: 11527378Abstract: It is a CNT device (1) (carbon-metal structure) equipped with a carbon nanotube layer (2) (CNT layer 2; same hereafter) on a metal pedestal (4). The metal pedestal (4) is brazed to the CNT layer (2) with a brazing material layer (3) interposed therebetween. When manufacturing the CNT device (1), firstly, the CNT layer (2) is formed on a heat-resistant textured substrate (6). Next, the metal pedestal (4) is brazed to the CNT layer (2) that is on the heat-resistant textured substrate (6) with the brazing material layer (3) interposed therebetween. Then, the metal pedestal (4) (and the CNT layer 2) is peeled off the heat-resistant textured substrate (6) to transfer the CNT layer (2) from the heat-resistant textured substrate (6) to the metal pedestal (4).Type: GrantFiled: October 21, 2019Date of Patent: December 13, 2022Assignees: WASEDA UNIVERSITY, MEIDENSHA CORPORATIONInventors: Suguru Noda, Sae Kitagawa, Kotaro Yasui, Hisashi Sugime, Daizo Takahashi, Yuichi Nishikiori, Hayato Ochi, Rena Takahashi, Toshimasa Fukai

Patent number: 8755166Abstract: A vacuum capacitor includes a fixed electrode, a movable electrode, a movable electrode shaft, a magnetic flux receiving unit, a magnetic flux generating unit and a capacitance control unit. The fixed electrode is formed from a plurality of electrode members in a vacuum casing. The movable electrode is formed from a plurality of electrode members arranged in gaps formed between the electrode members of the fixed electrode in the vacuum casing. The movable electrode shaft supports the movable electrode. Capacitance appearing between the movable electrode and the fixed electrode is varied by rotation of the movable electrode shaft. The magnetic flux receiving unit rotates the movable electrode shaft in the vacuum casing. The magnetic flux generating unit is located outside the vacuum casing and rotates the magnetic flux receiving unit by magnetic attraction. The capacitance control unit rotates the magnetic flux generating unit.Type: GrantFiled: November 19, 2009Date of Patent: June 17, 2014Assignee: Meidensha CorporationInventors: Eiichi Takahashi, Toshimasa Fukai, Toshinori Tatsumi, Yuichi Nishikiori, Kaoru Kitakizaki, Toru Tanimizu

Patent number: 8749946Abstract: A vacuum capacitor includes a fixed electrode, a movable electrode, a movable electrode shaft, a magnetic flux receiving unit, a magnetic flux generating unit and a capacitance control unit. A plurality of electrode members in a vacuum casing form the fixed electrode. The fixed electrode is divided into a plurality of fixed electrodes, and each fixed electrode is lead outside the vacuum casing and electrically connected to each other in series. A plurality of electrode members arranged in gaps between the electrode members of the fixed electrode form the movable electrode. Rotating the movable electrode shaft, which supports the movable electrode, varies capacitance between the movable electrode and the fixed electrode. The magnetic flux receiving unit rotates the movable electrode shaft. The magnetic flux generating unit, located outside the vacuum casing, rotates the magnetic flux receiving unit by magnetic attraction. The capacitance control unit rotates the magnetic flux generating unit.Type: GrantFiled: November 19, 2009Date of Patent: June 10, 2014Assignee: Meidensha CorporationInventors: Eiichi Takahashi, Toshimasa Fukai, Toshinori Tatsumi, Yuichi Nishikiori, Kaoru Kitakizaki, Toru Tanimizu

Patent number: 8749947Abstract: The present invention can easily adjust capacitance of a vacuum capacitor while maintaining a vacuum state in a vacuum chamber of the vacuum capacitor. A fixed electrode 4 is formed by arranging a plurality of flat electrode members 5 in layers at a certain distance in an axial direction of a vacuum chamber 1b. A movable electrode 7 is formed by arranging a plurality of flat electrode members 8 in layers at a certain distance in the axial direction of the vacuum chamber 1b and fixing the electrode members 8 to a movable electrode shaft 9. By rotation of the movable electrode shaft 9, each electrode member 8 is inserted into and extracted from a gap between the electrode members 5 of the fixed electrode 4 in noncontact with the electrode members 5 of the fixed electrode 4. A magnetic flux receiving portion 106b is fixed to a seal member 102 side of a disk member 106a that is provided at the movable electrode shaft 9.Type: GrantFiled: March 28, 2011Date of Patent: June 10, 2014Assignee: Meidensha CorporationInventors: Eiichi Takahashi, Toshimasa Fukai, Toshinori Tatsumi, Yuichi Nishikiori, Kaoru Kitakizaki
