Patent number: 10230455Abstract: A communication system includes a source node and an end node of a first working path, a source node and an end node of a second working path, and a source node and an end node of a common path serving as a protection path shared by the first and second working paths. The source node of the common path transfers one of signals received from the source nodes of the first and second working paths to the common path, and the end node of the common path transmits the signal received through the common path to each of the end nodes of the first and second working paths.Type: GrantFiled: July 25, 2016Date of Patent: March 12, 2019Assignee: FUJITSU LIMITEDInventors: Shingo Hironaka, Takashi Honda

Publication number: 20170005934Abstract: A transmission device includes a plurality of first cards each being coupled to a first line through which a first signal is transmitted, and a second card coupled to a second line through which a second signal enabling insertion of the first signal is transmitted. The transmission device determines whether or not a data amount of the first signal exceeds a predetermined threshold in the first card, and when the data amount of the first signal exceeds the predetermined threshold, the transmission device causes the second card to set, based on destination information in the first signal, the second line through which the first signal is to be transferred.Type: ApplicationFiled: June 20, 2016Publication date: January 5, 2017Applicant: FUJITSU LIMITEDInventors: Shingo HIRONAKA, Takashi HONDA

Patent number: 8830942Abstract: Mobile equipment includes a second control unit connected to a plurality of first control units performing control of an application function. The second control unit includes a storage unit, a setting unit, a transmitting unit, and a selecting unit. The storage unit stores selection information and connecting-destination specifying information associating each other. The setting unit sets the connecting-destination specifying information for a connecting-destination connected with the mobile equipment via a connection between the mobile equipment and a communication network. The transmitting unit transmits the connecting-destination specifying information set by the setting unit to the first control unit having the application being an establishment requestor of the connection.Type: GrantFiled: September 21, 2012Date of Patent: September 9, 2014Assignee: Fujitsu LimitedInventors: Masaya Oda, Akihiro Sato, Daisuke Kobayashi, Shingo Hironaka, Hidekazu Makino, Yuichiro Oishi

Publication number: 20100051240Abstract: A variable conductance heat pipe is provided. The variable conductance heat pipe includes a sealed container in which a working fluid and a noncondensable gas are sealed, the sealed container extending in an axial direction. The sealed container includes one end to be connected to a heating source and a part to be connected to a heat sink. On a cross section of the sealed container along a direction orthogonal to the axial direction, a portion having water conveying property better than other portions is provided. The portion having the better water conveying property extends in the axial direction.Type: ApplicationFiled: August 27, 2009Publication date: March 4, 2010Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Shigetoshi IPPOSHI, Tetsuya Nagayasu, Shingo Hironaka, Kuraki Kitazaki, Yukio Sato
