Patent number: 10178799Abstract: A superconducting fault current limiter (10) is provided with superconducting elements (71, 72) that are in a superconducting state during electrification with a current value in a fixed range and in a normal conducting state during electrification with a fault current in which the current value exceeds the fixed range and is further provided with a coolant vessel (20), which accommodates a liquid coolant (60) and a plurality of superconducting elements, and a cooling means (40) that cools the liquid coolant within the coolant vessel. Within the liquid coolant, the superconducting element (71) for which the critical current is smallest among the plurality of superconducting elements is disposed on the upper side of any other superconducting elements (72). Thus, the superconducting element (71) is cooled, and the life of the superconducting fault current limiter as a whole is extended.Type: GrantFiled: February 7, 2014Date of Patent: January 8, 2019Assignee: FURUKAWA ELECTRIC CO., LTD.Inventors: Hajime Kasahara, Tomohiro Nakayama, Masakazu Matsui

Publication number: 20150099640Abstract: A cooling container accommodates an object to be cooled and a liquid coolant in the inside. A lid member can close an upper opening of the coolant container. A cooling device is supported by the lid member and includes a cooling section at a lower end. Electric current leads supported by the lid member make electric current flow into the object to be cooled inside the coolant container. The electric current leads each include a thermal resistance section with higher thermal resistance than surrounding portions, positioned above the liquid surface of the liquid coolant in the coolant container. Between the thermal resistance sections and the cooling section, a partition section made from a heat insulation material with a lower end below the thermal resistance sections is provided. An effect of penetrating heat can be prevented, allowing the inside of the coolant container to be efficiently cooled.Type: ApplicationFiled: January 29, 2013Publication date: April 9, 2015Applicant: FURUKAWA ELECTRIC CO., LTD.Inventors: Hajime Kasahara, Taro Matsuoka, Masakazu Matsui

Patent number: 8763032Abstract: A first terminal sends a message to an application server in order to redirect the same content object to a second terminal. The application server receives the message and forwards it with content object preference of the second user to the content server. The content server redirects distribution of the content object with the advertisement to the second terminal. The advertisement is personalized for the second user based on the content object preference of the second user. The advertisement for the first user is also personalized based on a content object preference of the first user. The first and second users enjoy the same content object with the different advertisement.Type: GrantFiled: July 25, 2008Date of Patent: June 24, 2014Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Johan Hjelm, Shingo Murakami, Hajime Kasahara, Toshikane Oda
