摘要： A method of producing a sulfide solid electrolyte material includes: forming an intermediate having crosslinking sulfur but no Li2S, by vitrifying, in a first vitrification process, a starting material composition obtained by mixing Li2S and a sulfide of a group 14 or group 15 element such that a proportion of Li2S with respect to the sum total of the Li2S and the sulfide of a group 14 or group 15 element is smaller than a proportion of Li2S required for the sulfide solid electrolyte material to obtain an ortho composition; and eliminating the crosslinking sulfur by vitrifying, in a second vitrification process, an intermediate-containing composition resulting from mixing a bond cleaving compound, which cleaves a bond of the crosslinking sulfur, with the intermediate.

摘要： For a semiconductor circuit having one or more semiconductor devices, such as an IGBT, a turn-ON prevention circuit is provided for each device which prevents the device from turning ON during OFF times thereof, due to the presence of a transient voltage (dV/dt) across the main terminals of the device. In accordance with such a scheme, a MOSFET is connected between the insulated-gate electrode and emitter of the IGBT, and a capacitor, for example, is connected between the gate of the MOSFET and a sufficient electric potential to thereby effect a temporary turn-ON of the MOSFET to remove parasitic charge build-up in the IGBT before such charge build-up has reached a potential of the turn-ON threshold of the IGBT during OFF times of the IGBT. The capacitance element can be constituted by a MOSFET, namely, the capacitance across the gate-to-drain of an additional MOSFET. As a result, therefore, power consumption can be kept sufficiently small and the chip area required for implementing the circuit, such as, in a monolithic construction can be reduced. Further, the turn-ON prevention scheme can be applied to MOSFET devices rather than IGBTs.
