Patent number: 7943241Abstract: A composite ceramic body and a method thereof are provided. The composite ceramic body comprising a first bonding body comprising a ceramic containing Si ingredient, and a second bonding body bonded to the first bonding body through a bonding material containing, as main ingredient, a Si compound which includes the element common to the Si ingredient contained in the first bonding body. The first and second bonding bodies can be bonded strongly and uniformly without any adhesive. Since the composite ceramic body has high bonding strength, it is applicable to microchemical chips and reformers.Type: GrantFiled: November 29, 2005Date of Patent: May 17, 2011Assignee: Kyocera CorporationInventors: Junji Kurokawa, Kazutsugu Kobayashi, Motoaki Yoshida, Masahiro Okumura, Atsushi Ogasawara, Tetsurou Abumita, Takeshi Ogawa, Masakazu Yasui

Patent number: 7537098Abstract: An electromagnetic clutch (20) capable of connecting and disconnecting a driving power source and a rotary shaft (22) includes a rotor (25) rotated by the driving power source, and an armature (40) capable of being attracted to the rotor (25) by electromagnetic force to produce a transmission force transmitted from the rotor (25) to the rotary shaft (22). The electromagnetic clutch (20) further includes leaf springs (52) urging the armature (40) in such a direction as to separate the armature from the rotor (25). The leaf springs (52) each assume an orientation such that a boost force assisting the attractive force acting upon the armature (40) is produced based on the transmission force when the armature (40) is attracted to the rotor (40).Type: GrantFiled: July 23, 2004Date of Patent: May 26, 2009Assignee: Sanden CorporationInventors: Shigeru Ito, Hirokazu Ichinose, Motoaki Yoshida, Isamu Shirai

Publication number: 20080287236Abstract: A pulley in which screw holes can have a sufficient axial-direction length without thickening a projecting part. The pulley comprises a pulley main body (10) and flat members (20) fixed thereto, the flat members (20) having screw holes (20c) formed therein. Consequently, there is no need of forming screw holes in the pulley main body (10) and, hence, the screw holes (20c) can have a sufficient axial-direction length without the need of thickening the projecting part (12). Namely, a weight reduction can be attained by thinning the projecting part (12) and a reduction in production cost can be attained by the weight reduction.Type: ApplicationFiled: October 17, 2006Publication date: November 20, 2008Applicant: SANDEN CORPORATIONInventors: Tomomi Yamaguchi, Motoaki Yoshida, Hirokazu Ichinose, Atsushi Ozawa
