Abstract: The present invention relates to a compound capable of lowering the flammability of a non-aqueous electrolyte when included in the non-aqueous electrolyte and improving the life properties of a battery by forming an electrode-electrolyte interface which is stable at high temperatures and low in resistance, and relates to a compound represented by Formula I descried herein, a non-aqueous electrolyte solution and a lithium secondary battery both including the compound, n, m, Ak, and X are described herein.

Abstract: Disclosed is a high voltage output device having a serial-parallel stack structure of capacitors. The high voltage output device includes a substrate includes a capacitor element and a pillar structure provided on an upper surface of the substrate. The substrate includes a first electrode and a second electrode, which have different potentials from each other. The capacitor element is connected to at least one of the first electrode and the second electrode.

Abstract: An emergency generator power system with reserved fire protection power includes a generator engine and a generator body, a main power circuit breaker, a control panel, and a circuit breaker for fire protection systems and a circuit breaker for other emergencies. The generator power system also includes a measuring instrument and a control instrument. The measuring system measures a power load change on a main power line passing via the main power circuit breaker. The control instrument is connected to the measuring instrument at an input side thereof and to the circuit breaker for other emergencies at an output side thereof. When the value of the power load change reaches a predetermined value, the circuit breaker for other emergencies is primarily broken, thereby keeping the main power circuit breaker from being broken before the breaking of the circuit breaker for other emergencies.

Abstract: The present invention relates to an emergency generator power system with reserved fire protection power used for fire protection systems and other emergencies at the time of stop of supplying of normal power and comprising a generator engine and a generator body, a main power circuit breaker, a control panel, and a circuit breaker for fire protection systems and a circuit breaker for other emergencies branched therefrom respectively. The present invention is characterized in that, when a fire and an interruption of power occur in buildings or facilities in which the emergency generator power system is to be installed, power load other than power load for fire protection systems is primarily interrupted, thereby emergency power is safely supplied to the power load for fire protection systems.
