Patent number: 7794306Abstract: An apparatus and method for surface finishing a workpiece is disclosed as including a workpiece supporting mechanism supporting a workpiece having a target shaped periphery with a given width to be surface finished and a tool holder holding a surface finish tool in abutting contact with the target shaped periphery of the workpiece. A pressure applying mechanism is operative to apply a pressure force to the surface finish tool through the tool holder to cause the surface finish tool to be held in pressured contact with the target shaped periphery, with the pressure force exhibiting a given distribution pattern depending upon an axial direction of the workpiece. A drive mechanism rotates the workpiece to allow the surface finish tool to surface finish the target shaped periphery into a given geometrical profile, variably contoured along an axis of the workpiece depending on the given pressure distribution pattern.Type: GrantFiled: February 6, 2004Date of Patent: September 14, 2010Assignee: Nissan Motor Co., Ltd.Inventors: Tomohiro Kondo, Masahiko Iizumi, Masahiro Omata, Kiyoshi Hasegawa, Takashi Ogino, Takafumi Watanabe, Yoshiyuki Chida, Yasushi Matsushita, Kazuo Takeda

Publication number: 20100036029Abstract: Disclosed are: a high-performance polyphenylene ether-organoclay complex which is significantly improved in fire retardancy, durability (e.g., light resistance, chemical resistance, impact resistance), an ability of being extruded into a sheet and the like; and others. The polyphenylene ether-organoclay complex can be produced by: preparing a mixture comprising a solvent, a catalyst, a phenolic compound and an organoclay, wherein the organoclay is contained in an amount of 0.1 to 20 parts by mass relative to 100 parts by mass of the phenolic compound; contacting the mixture with an oxygen-containing gas to cause the oxidative polymerization of the phenolic compound; and removing the solvent and the catalyst from the resulting polymerization mixture. This method is applicable to the production of a complex of an organoclay with other polymers such as an aromatic polycarbonate, a polyether imide and a polyacrylate.Type: ApplicationFiled: February 22, 2008Publication date: February 11, 2010Applicant: ASAHI KASEI CHEMICALS CORPORATIONInventors: Toru Yamaguchi, Tomohiro Kondo, Akira Mitsui

Patent number: 7625313Abstract: In a shift control device and a shift control method of a vehicular automatic transmission that performs a coast downshift by engagement switch between a release-side engagement element and an element-side engagement element at a time of deceleration of a vehicle, it is determined whether or not there is a driver's intention to decelerate the vehicle during the coast downshift. If an affirmative determination is made regarding the intention to decelerate the vehicle, the rise of engagement pressure of the engagement-side engagement element is stopped so as to cause the coast downshift not to progress. If a negative determination is made regarding the intention to decelerate the vehicle while the rise of the engagement pressure has been stopped, the engagement pressure of the engagement-side engagement element is raised again so as to cause the coast downshift to progress.Type: GrantFiled: December 5, 2006Date of Patent: December 1, 2009Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tomohiro Kondo, Yoji Takanami, Atsushi Ayabe, Masami Kondo, Masaharu Tanaka
