Patent number: 8763746Abstract: A mounting structure of a handle switch device with which a panel can be replaced by manipulating fasteners for fastening two outer casings of the handle switch device together. A rear casing is temporarily mounted to an inner casing that is mounted to a handle pipe, engagement pieces of a design panel are inserted through through holes of a front casing, and the front and rear casings are fastened together by mounting screws, thereby completing assemblage of the handle switch device. To replace the design panel, the mounting screws are loosened to bring them into a half-engagement state and the front casing is displaced toward a driver side to disengage projection ribs of the inner casing from the through holes. Next, the design panel is dismounted from the front casing, a new design panel is mounted to the front casing, and the mounting screws are tightened.Type: GrantFiled: November 30, 2012Date of Patent: July 1, 2014Assignee: Toyo Denso Kabushiki KaishaInventors: Tsutomu Tozuka, Shigeharu Nazu, Keisuke Hojo

Publication number: 20110298741Abstract: The touch-operating input device is configured so that when the control circuit turns on the main light source corresponding to each of the translucent operation buttons that can be operated, the control circuit, on condition that the translucent operation button corresponding to the main light source that is turned on is operated, turns off the sub-light source corresponding to the translucent operation button that is turned on simultaneously with the main light source. Ease of operation is increased by enabling the operator to distinguish operated translucent operation buttons from translucent operation buttons that have not been operated according to whether or not the main light sources are lit.Type: ApplicationFiled: February 22, 2010Publication date: December 8, 2011Applicant: TOYO DENSO KABUSHIKI KAISHAInventors: Naohiro Sakai, Yoshitaka Noguchi, Shigeharu Nezu

Patent number: 7796004Abstract: An ignition coil of a dual ignition type that can prevent outputs from becoming unbalanced due to a difference in floating capacitance on wiring that connects secondary output terminals and ignition plugs together, thus realizing balanced outputs. A coil assembly housed in a housing as a coil case has a primary coil and secondary coils disposed concentrically with the primary coil. The secondary coils are comprised of two coils wound in opposite directions with the center of winding width being a boundary. The center of the winding width of the primary coil is shifted from the center of the winding width of the secondary coils by a predetermined width so as to balance outputs from the two secondary coils.

Patent number: 7591174Abstract: A rudder angle sensor with high accuracy, including a memory for storing a correction value to correct a rotational delay of a driven gear relative to a main drive gear caused by a backlash at a time of reverse of a steering shaft, a computer for correcting the value measured by the measuring mechanism based on the correction value stored in the memory, to thereby, calculate the rotation angle of the steering shaft. The measured result of the driven gear obtained by the measuring mechanism is corrected based on the correction value, and therefore, the backlash existing between the main drive gear and the driven gear can be matched completely or approximately. Thus, the high accuracy angle sensor is realized.Type: GrantFiled: October 26, 2006Date of Patent: September 22, 2009Assignee: Toyo Denso Kabushiki KaishaInventor: Masahiro Matsuda
