| 20100031918 | NON-CONTACT IGNITION CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE - A no-contact ignition control device includes a stop switch which maintains a second switching element at the OFF state so that an induced voltage of a trigger coil triggers a first switching element and shortcircuit a generation coil. A surge absorption element is connected in parallel to the stop switch. This configuration prevents intrusion of a surge current into the ignition control circuit caused by static electricity accumulated on the surface of casing covering electronic parts of the ignition control circuit and surely avoid dielectric breakdown of the electronic parts or malfunction of the circuit by the surge current. | 02-11-2010 |
| 20090165541 | ENGINE ROTATING METER - A level adjusting circuit which adjusts input pulses from an antenna to a level suitable for determining the number of engine revolutions, is connected in a circuit that connects the antenna with a determining circuit. An optimum adjustment of the determination level by manual operation allows the pulses inputted to the determining circuit to be precisely determined at all times. | 07-02-2009 |
