摘要： At least one of center and ground electrodes of a spark plug has a thin layer formed by bonding noble metal powder on a discharge-related surface area of the electrode stock of said at least one of said center and ground electrodes in accordance with ultrasonic bonding. Instead of the thin layer, a discharge tip may be formed there by boring a hole in the electrode stock, filling noble metal powder, which has been obtained by coating spherical or flaky metal particles with a corresponding noble metal or noble metal alloy, in the hole and then bonding the thus-filled noble metal powder in accordance with ultrasonic bonding. As a further alternative, a tip made of a noble metal or an alloy thereof may be bonded by ultrasonic bonding or resistance welding in the hole with a layer or metal powder of a metal having good high-temperature erosion resistance or an alloy thereof interposed therebetween. The spark plug enjoys a long operating life.

摘要： A voltage conversion apparatus includes a booster circuit, a boost stop circuit, a Zener diode, and a capacitor. The boost stop circuit includes a transistor. When an overvoltage equal to or larger than a breakdown voltage of the Zener diode is output to an output line of the booster circuit, the Zener diode is turned on. Accordingly, the transistor is turned on and a switching element is turned off to stop a boost operation. Further, the capacitor is charged through the Zener diode. Even when the Zener diode is turned off due to a drop in the output voltage after the stop of the boost operation, the transistor maintains its on state for a certain time by discharge of the capacitor. Thus, the stop of the boost operation is continued.

摘要： A conductive resin composition which includes an epoxy resin (A), a compound (B) having a (meth)acryloyl group and a glycidyl group, a phenolic resin curing agent (C), a radical polymerization initiator (D) and a conductive particle (E). The conductive resin composition which may be B-staged (semi-cured) at a relatively low temperature to exhibit sufficient tack-free properties and excellent pressure-sensitive tackiness. This permits temporary bonding of parts without involving solvent evaporation or light illumination, thereby reducing or avoiding an increase in facility costs. The conductive resin composition may thereafter be cured (C-staged) to provide a cured product having a desirable bond strength, while maintaining a low specific resistivity.

摘要： A LPF extracts DC component of a current detection value of an inverter input current. A subtracting section 4 calculates a difference between a current command value and the DC component of the current detection value. A current controller 5 produces two-phase PWM signals Sa and Sb complementary to each other, from the current difference. Further, an integrating circuit 7 integrates output terminal voltages Vu, Vv and Vw of the inverter to convert the output terminal voltages Vu, Vv and Vw into a magnetic-flux information Φu, Φv and Φw. A logic conversion section 8 converts the magnetic-flux information Φu, Φv and Φw into 120-degree conduction patterns S1′-S6′ to output the 120-degree conduction patterns S1′-S6′. Then, a logic circuit section 9 executes a logic synthesis between the PWM signals Sa and Sb and the 120-degree conduction patterns S1′-S6′ to output gate signals S1-S6.
