Patent number: 8800710Abstract: A motorcycle with a muffler disposed downwardly of a rider's seat positioned, in a side view, upwardly of a rear wheel when a rear shock absorber is extended, to minimize sideway bulging of the muffler from a vehicle body and improve ride comfort, while avoiding interference between the muffler and other parts. An outer shell of a muffler has a rhombus cross section. The muffler is disposed on at least one side in a vehicle width direction of a rear wheel wherein one pair of side walls extend in parallel with each other out of side walls of the outer shell extending in a vertical direction. A side cover is formed to extend along the upper and outer side walls of the four side walls of the outer shell to cover the muffler from a side, downwardly of a rider's seat.Type: GrantFiled: March 5, 2013Date of Patent: August 12, 2014Assignee: Honda Motor Co., Ltd.Inventors: Yoshitaka Hayama, Takuya Otsuka, Yusuke Inoue, Satoshi Matsushima

Patent number: 8228665Abstract: The object is to provide ring-bus-type gas insulated switchgear that ensures maintenance and inspection performance, reduces the installation space, and further reduces costs. Each of a plurality of breaker units is formed by connecting an instrument current transformer and a disconnector to each of the upper and lower branch ports drawn horizontally from the side surface of a vertical breaker in the same direction, and the breaker units are arranged in parallel. Adjacent disconnectors are connected to each other by a connection bus, so that the bus route runs alternately at upper and lower levels. Furthermore, the breaker units positioned at the two ends are connected linearly to each other by a communication bus. In addition, the line-side devices are arranged to face the corresponding breaker units across the disconnectors.Type: GrantFiled: November 1, 2007Date of Patent: July 24, 2012Assignee: Mitsubishi Electric CorporationInventors: Daisuke Fujita, Takuya Otsuka, Hitoshi Sadakuni

Patent number: 8000087Abstract: Each integral unit is structured by arranging partial units (I), (II), and (Ill) side by side, while line-side devices are branched from positions between the partial units adjacent to each other. Each of the partial units is structured by connecting a current transformer and a disconnector in sequence to each of upper and lower outlets horizontally drawn out from a lateral face of a vertical-type circuit breaker in the same direction. Any two partial units positioned adjacent to each other are connected in series by connecting the disconnectors included therein with a connection bus. The line-side devices are positioned to oppose the circuit breakers while the disconnectors are interposed therebetween. The switchgear includes a plurality of integral units. Two ends of each of the integral units are respectively connected to two main buses that are provided in an upper position and a lower position while the disconnectors are interposed therebetween.Type: GrantFiled: November 29, 2007Date of Patent: August 16, 2011Assignee: Mitsubishi Electric CorporationInventors: Daisuke Fujita, Takuya Otsuka, Hitoshi Sadakuni
