Publication number: 20070239334Abstract: A turning motion control system for a vehicle includes an actuator, and an actuator control device for controlling the actuator so that an actual turning motion state of the vehicle becomes close to a target turning motion state. The actuator control device is designed so that its control-permitted state and its control-stopped state can be switched from one to another through a switching device operated by a driver. When an air-pressure decreased state detecting device has detected an air-pressure decreased state, the actuator control device carries out the control of the operation of the actuator, irrespective of a switching mode of the switching device. Thus, even if an air-pressure decrease or an abnormality is generated in any of wheels in a state in which the turning motion control by the actuator has been stopped, the stability of the vehicle can be ensured.Type: ApplicationFiled: May 31, 2007Publication date: October 11, 2007Applicant: HONDA MOTOR CO., LTD.Inventors: Nobuyuki Imaizumi, Yoshihiro Iwagawa, Susumu Ohta, Kazunari Okada, Hironobu Kiryu, Kazuya Sakurai, Masakazu Shiraishi, Tomoaki Sugano, Toshio Yahagi

Patent number: 7227051Abstract: A disposable wearing article includes a liquid-pervious topsheet, a liquid-impervious backsheet, a liquid-absorbent core interposed between the top- and backsheets, a pair of liquid-impervious leak-barrier sheets and a pair of elastically stretchable sheets. Each portion of the aforesaid sheets placed one upon another are joined together by means of adhesives and the core is joined to inner surfaces of the top- and backsheets by means of adhesives. Adhesives are defined by a plurality of adhesive lines continuously extending in a given direction and each of the adhesive lines includes first and second zones arranged alternately in the given direction along the adhesive line. A quantity of adhesives in the first zone is much more than a quantity of adhesives in the second zone.Type: GrantFiled: December 17, 2003Date of Patent: June 5, 2007Assignee: Uni-Charm CorporationInventors: Koichiro Mitsui, Masakazu Shiraishi, Yasushi Sayama

Patent number: 6336689Abstract: A brake fluid pressure retaining unit for a vehicle comprises a solenoid valve SV arranged in a brake fluid passage FP between a master cylinder MC and a wheel cylinder WC so as to shut off or communicate the brake fluid passage FP. In the case that a transmission of the vehicle is shifted to a driving position, the solenoid valve SV is switched to a shut-off position when the vehicle stops with a brake pedal BP depressed. The solenoid valve SV is switched to a communicating position when driving force is exerted on the vehicle. Brake fluid pressure is retained within the wheel cylinder WC when the solenoid valve SV is in the shut-off position. The brake fluid pressure within the wheel cylinder is retained after releasing the brake pedal so that braking force continues to act on the vehicle.Type: GrantFiled: March 2, 2000Date of Patent: January 8, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takahiro Eguchi, Hirotoshi Inoue, Toshiya Kanda, Masakazu Shiraishi, Shouji Suzuki, Yoichi Sugimoto
