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.
