Patent number: 11338830Abstract: There is provided an underfloor duct which enables inspection of electric equipment to be easily performed, has a simple structure, and hardly allows water to intrude into a duct passage. An underfloor duct according to an aspect of the present invention is an underfloor duct, provided under a floor of a railcar, for storing electric equipment including a cable. The underfloor duct includes: a box having a frame that projects upward, and an opening that opens downward; and a lid that closes the opening and forms a duct passage between the lid and the box. An end portion of the box is located outside an end portion of the lid in a car width direction.Type: GrantFiled: October 29, 2018Date of Patent: May 24, 2022Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Mitsuru Yokoyama, Kazuya Tanigawa

Patent number: 8283945Abstract: FPGAs and MPLDs, which are conventional programmable semiconductor devices, have had poor cost performance and did not suitably take long signal lines into account. To solve this, a flip-flop is built into each MLUT block comprised of a plurality of MLUTs, each MLUT comprising a memory and an address-data pair. With respect to the adjacent line between adjacent MLUTs, alternated adjacent line are introduced, while in the case of interconnects between non-adjacent MLUTs, dedicated distant line and, furthermore, a torus interconnect network are provided.Type: GrantFiled: March 24, 2010Date of Patent: October 9, 2012Assignee: Taiyo Yuden Co., Ltd.Inventors: Tetsuo Hironaka, Kazuya Tanigawa, Hiroaki Toguchi, Naoki Hirakawa, Takashi Ishiguro, Masayuki Sato
