摘要： The present invention provides an electric double layer capacitor which has electrodes made of an alkali-activated carbon, prepared from a graphitic material, useful in manufacturing high-capacitance capacitors and which has an electrolytic solution containing chain carbonate and/or cyclic carbonate. Even if the electric double layer capacitor is used under high-temperature and high-voltage conditions, chain carbonate and/or cyclic carbonate is prevented from being degraded and the amount of generated gas is slight. The electric double layer capacitor has high initial performance and energy density and the performance of the electric double layer capacitor is maintained high. The electrolytic solution contains a quaternary ammonium salt except for a quaternary ammonium salt containing a carbon atom being bonded to the quaternary nitrogen atom and being bonded to other nitrogen atom than the quaternary nitrogen atom, chain carbonate and/or cyclic carbonate, and a solvent containing a carboxylic ester which contains five or more carbon atoms and which has two or more carboxylic ester bonds.

摘要： An oscillator comprising a delay circuit having an input terminal and an output terminal, and a tristate inverter having an input connected to the output terminal of the delay circuit and an output connected to the input terminal of the delay circuit. This tristate inverter is adapted to be switched by a control signal between an operable condition and an inoperable condition. A wave shaping inverter is connected to the output of the tristate inverter to generate a shaped pulse signal. Further, there is provided at least one tristate inverter having an input directly connected to an output of the tristate inverter itself so that it can generate a predetermined potential corresponding to the threshold of the tristate inverter itself. This voltage generating tristate inverter is connected at its output terminal to a selected one of the input and output terminals of the delay circuit. This voltage generating tristate inverter is adapted to be put in response to the control signal, when the first tristate inverter is put in the operable condition, in such a biasing mode as to generate the above predetermined voltage at the output terminal, and when the first tristate inverter is put in the operable condition, in such a floating mode as to bring its output terminal into a floating condition, so that the first tristate inverter oscillates because of a feedback given by the delay circuit.
