Patent number: 7219524Abstract: A high-pressure piping part includes a body structure forged in a closed space. The body structure is formed to include a main body portion formed by forward extrusion and side arm portions formed by side extrusion. The main body portion has therein a fiber flow formed along a passage, and the side arm portion has therein a fiber flow formed along the passage. Therefore, the direction in which stress is applied to the passage of the body structure by an internal pressure is approximately perpendicular to the directions of the fiber flows, thereby improving the degree of allowance of the resistance to pressure of the body structure for an injector.Type: GrantFiled: December 19, 2005Date of Patent: May 22, 2007Assignee: Denso CorporationInventors: Shu Miyashita, Masami Tanaka, Toshihiro Imai, Hirofumi Muranaka

Patent number: 7099763Abstract: A vehicle speed memory unit stores a vehicle speed at a prior predetermined time, the vehicle speed being calculated from an interval of the vehicle speed pulse. A first rapid deceleration detecting section compares an elapsed time from a time the vehicle speed pulse signal is inputted, measured by an elapsed time measuring unit, with a pulse interval corresponding to a predetermined deceleration relative to a vehicle speed stored by the vehicle speed memory unit, or a second rapid deceleration detecting section calculates an undetermined vehicle speed from the elapsed time measured by the elapsed time measuring unit, and calculates a deceleration from the undetermined vehicle speed and the vehicle speed at the prior predetermined time, and compares the calculated deceleration with a predetermined deceleration threshold value. Thus, rapid vehicle deceleration can immediately be determined at the present time without waiting for the determination of the vehicle speed after input of the next pulse signal.Type: GrantFiled: September 24, 2003Date of Patent: August 29, 2006Assignee: Jatco LTDInventors: Masami Tanaka, Nobuyori Nakajima
