Patent number: 8376112Abstract: A drive force transmitting apparatus comprises a dry clutch, a hydraulic cylinder, a piston arm, an elastic partitioning member, a first seal member and a leakage lubricating fluid recovery path. The elastic partitioning member prevents lubricating fluid that has leaked from a sliding portion of a piston of the hydraulic cylinder from flowing into the dry clutch. The first seal member is disposed between opposing surfaces of a cylinder housing and a clutch cover at a position downstream from the elastic partitioning member in a leakage flow direction of lubricating fluid that has leaked. The leakage lubricating fluid recovery path is at least partially formed by a gap between the cylinder housing and the clutch cover, such that lubricating fluid leaking past the piston is conveyed to an inside of the transmission while maintaining a sealed state established by the elastic partitioning member and the first seal member.Type: GrantFiled: May 11, 2010Date of Patent: February 19, 2013Assignee: Nissan Motor Co., Ltd.Inventors: Takashi Kuwahara, Yasuo Takagi

Patent number: 8346161Abstract: When a transmission request for new data is issued under a situation where a plurality of data are transmitted to a specific service area from a plurality of service areas, a feeder link station searches an available frequency to be allocated to the new data in a down-link frequency band of the specific service area, and when any of data communications is completed, allocates a down-link frequency band used in the data communication as a down-link frequency band for the new data. A satellite repeater arranges the new data on the down-link frequency band right after the data communication is completed following a relay control by the feeder link station.Type: GrantFiled: May 15, 2007Date of Patent: January 1, 2013Assignee: Mitsubishi Electric CorporationInventors: Yasushi Sogabe, Akinori Fujimura, Takashi Kuwahara, Futaba Ejima

Patent number: 7439114Abstract: For obtaining p-Si by irradiating a laser beam to an a-Si layer to polycrystallize, an energy level in a region to be irradiated by the laser beam is set such that a level at the rear area of the region along a scan direction of the laser beam is lower than that at the front area or the center area of the region. The energy level at the front area or the center area of the region is set such that it is substantially equal to or more than the upper limit energy level which maximizes a grain size of the p-Si obtained. Since an energy profile is set as described above, when the laser beam is scanned on the a-Si layer, an irradiated energy of the laser on the region is gradually lowered from the upper limit as the laser beam passes through, which allows the semiconductor layer to be annealed within an optimal energy level during the latter half of the annealing process.Type: GrantFiled: August 18, 2005Date of Patent: October 21, 2008Assignee: Sanyo Electric Co., Ltd.Inventors: Hidenori Ogata, Ken Wakita, Kiyoshi Yoneda, Yoshihiro Morimoto, Tsutomu Yamada, Kazuhiro Imao, Takashi Kuwahara
