Title: Ground and fault contact detecting system
Inventor: YAMAGUCHI TAKASHI
IPC: H04M19/00
Filed: 1988-06-03
Abstract: PURPOSE:To detect the trouble of ground and fault contact without receiving an influence in a feeding condition by defining a current, for which the differential current of first and second output currents in a first feeding circuit and the differential current of third and fourth output currents in a second feeding circuit are added, as a trouble detecting signal. CONSTITUTION:The respective differential current detecting circuits of a NOR feeding circuit 1 and a REV feeding circuit 2 detect a current to be proportional to a differential current, which is generated in an A-line current and a B-line current, and voltage detection is executed to the sum current of these currents by a differential detection resistor R70. Then, the voltage is compared with a reference voltage by a comparator 11. Thus, even if any feeding circuit is in an operating condition, the ground trouble can be detected regardless of the output limit of a balance circuit. Thus, the ground and fault contact detecting of high reliability can be executed with being applied to the feeding circuit of a public subscriber circuit.

Title: Igniting apparatus for internal-combustion engine
Inventor: YAGI GIICHI
IPC: F02B1/04
Filed: 1983-07-25
Abstract: PURPOSE:To prevent occurrence of engine trouble and to lower the cost of an igniting apparatus for a rotary engine, by using a diode distributor type ignition coil on the trailing side of the igniting apparatus and using the diode distributor type or a simultaneous ignition type ignitioncoil on the leading side of the igniting apparatus. CONSTITUTION:In the drawing, a rotor 11 of a rotary engine is in the state of starting explosion, that is, in the state of causing ignition, while a rotor 12 is in the state of starting exhaust or compression stroke. At the time of igniting plugs 7, 9 of the rotor 11, main spark is emitted to the plugs 7, 9 and ineffective spark is emitted to a plug 8. However, since a diode distributor type ignition coil 2 is used in this engine, ineffective spark is not emitted to a plug 10. Further, since combustion gas is charged in a rotor space 12a and unburnt gas is charged in a rotor space 12b, emission of spark to the plug 8 does not cause any trouble. However, if spark is emitted to the plug 10, unburnt gas is ignited, so that engine trouble is caused. On the other hand, an igniting apparatus using a diode distributor type ignition coil which does not cause ineffective emission of sparks is used on the trailing side, so that engine trouble is not caused.
