Publication number: 20110060479Abstract: An electronic device includes an electronic control unit, a wire, and a wiring-side connector. When a movable member is arranged in a first arrangement relative to a wiring-side connector main body, the movable member is in a position where the movable member does not prevent the wire from projecting from the main body to extend straight in a counter-fitting direction. When the movable member rotates from the first arrangement to a second arrangement relative to the main body, a restricting member approaches a portion of the main body from which the wire projects, to press and bend the wire, so a direction in which the wire projects from the main body is limited to a direction crossing the counter-fitting direction. When the movable member is arranged in the second arrangement and the main body is fitted to an ECU-side connector, the second arrangement is maintained.Type: ApplicationFiled: September 7, 2010Publication date: March 10, 2011Applicants: DENSO CORPORATION, Fujikura Ltd.Inventors: Toshio Hosokawa, Yasuo Takemura, Yuji Ishitani

Publication number: 20070057395Abstract: A polyglycolic acid resin is used as a forming aid to efficiently produce various shapes, such as porous film, ultrafine fiber, ultrafine film and porous hollow fiber, of shaped products of substantially water-insoluble thermoplastic resins. More specifically, a shaped composite of the polyglycolic acid resin and the substantially water-insoluble thermoplastic resin is caused to contact an aqueous medium, thereby selectively removing the polyglycolic acid resin through solvolysis and extraction to leave a shaped product of the remaining thermoplastic resin. A glycolic acid aqueous produced by the solvolysis and extraction can be recycled into the polyglycolic acid resin as a forming aid via the formation of a concentrated glycolic acid oligomer and glycolide.Type: ApplicationFiled: May 26, 2004Publication date: March 15, 2007Inventors: Kazuyuki Yamane, Toshiya Mizuno, Yukichika Kawakami, Shiro Suzuki, Yoichiro Yamanobe, Toshio Hosokawa, Takumi Katsurao

Publication number: 20050154530Abstract: The present colliding obstacle detection apparatus comprises a pedestrian bumper, which is supported below a front bumper of the vehicle by a body of the vehicle, at least one collision detector, which is located on the pedestrian bumper, and a control circuit, which determines whether the collision has actually occurred based on a detection signal outputted by the at least one collision detector. The front end of the pedestrian bumper vertically aligns with or extending ahead of that of the front bumper. The at least one collision detector detects one of a collision of the pedestrian bumper with an obstacle, and a presence of the obstacle in a close proximity to the pedestrian bumper. When the control circuit determines that the collision has actually occurred, the circuit activates a colliding obstacle protector for protecting the obstacle, especially a pedestrian.Type: ApplicationFiled: December 9, 2004Publication date: July 14, 2005Inventors: Toshio Hosokawa, Tetsuya Takafuji, Yoshiyuki Hattori

Patent number: 6317202Abstract: A radar apparatus for automotive vehicles is provided which is designed to emit laser beams to scan a forward zone for detecting moving object such as preceding vehicles and a downward zone for detecting lane marks printed on a road surface for defining a traffic lane. The downward zone is wider than the forward zone horizontally. Each zone has a minimum width required for assuring desired accuracy of radar detection of an object, thereby minimizing the number of emissions of the laser beams, resulting in an increase in lifetime of a laser diode and production of unwanted data on roadside objects having a low probability that the vehicle will collide them. The apparatus also includes a light focusing mechanism which focuses the laser beam on a given area in the downward zone to increase the power density of a return of the laser beam.Type: GrantFiled: November 12, 1999Date of Patent: November 13, 2001Assignee: Denso CorporationInventors: Toshio Hosokawa, Takekazu Terui
