Publication number: 20160341220Abstract: A blower fan includes a plurality of blades radially extending from a boss provided at the rotary center and spaced apart from each other in the rotational direction, and a ring portion connecting outer peripheral ends of the blades in a ring shape. An inner peripheral wall surface of an end part on an air-flow downstream side of a cylindrical portion is disposed on the outside in a radial direction of the rotary shaft in the blower fan, with respect to an end part on the air-flow downstream side of the ring portion. The end part on the air-flow downstream side of the cylindrical portion is positioned outward in the radial direction of the rotary shaft, as toward the air-flow downstream side. Thus, the blower can prevent the backflow air from being swirled, thereby reducing noise.Type: ApplicationFiled: February 20, 2015Publication date: November 24, 2016Inventors: Toshikatsu KONDOU, Masashi MATSUKAWA, Youhei KAMIYA, Masaru KAMIYA, Takeshi MIYAMOTO, Isao KONDOH, Takashi ITO, Kazuhiro TAKEUCHI

Patent number: 8116427Abstract: A radiological imaging apparatus of the present invention comprises an image pickup device and a medical examinee holding device that is provided with a bed. The image pickup device includes a large number of radiation detectors and radiation detector support plates. A large number of radiation detectors are mounted around the circumference of a through-hole and arranged in the axial direction of the through-hole. The radiation detectors are arranged in three layers formed radially with respect to the center of the through-hole and mounted on the lateral surfaces of the radiation detector support plates. Since the radiation detectors are not only arranged in the axial direction and circumferential direction of the through-hole but also arrayed in the radial direction, it is possible to obtain accurate information about a ?-ray arrival position in the radial direction of the through-hole (the positional information about a radiation detector from which a ?-ray image pickup signal is output).Type: GrantFiled: June 21, 2011Date of Patent: February 14, 2012Assignee: Hitachi, Ltd.Inventors: Shinichi Kojima, Takashi Okazaki, Yuuichirou Ueno, Kikuo Umegaki, Kensuke Amemiya, Kazuhiro Takeuchi, Hiroshi Kitaguchi, Kazuma Yokoi, Norihito Yanagita

Patent number: 8044785Abstract: The degradation of a feeling of ride is prevented by preventing engagement/disengagement (sudden engagement/disengagement) of a motorcycle hydraulic clutch due to a lack of hydraulic pressure. Before a hydraulic sensor issues a hydraulic pressure-lowering detection signal Sx, an oil level sensor issues an oil level-lowering warning signal Sf in a state wherein a sufficient oil quantity is such so as not to bring an neutral drive switching clutch into a disengagement state is present even if hydraulic pressure lowers resulting from an inclined oil level due to sudden deceleration, sudden start, drive in a slope, or the like. Thus, the neutral drive switching clutch can be prevented from disengaging or engaging (suddenly disengaging or engaging).Type: GrantFiled: February 23, 2009Date of Patent: October 25, 2011Assignee: Honda Motor Co., Ltd.Inventors: Masaki Cho, Masahiko Nakatsuka, Yasutaka Usukura, Kazuhiro Takeuchi
