摘要： An electric device having a power supply using an electrical two-film capacitor (1) is proposed, which capacitor can be charged in a very short time, and a constant electrical power [lacuna] with a high degree of power utilisation, it being possible, in an electric device of the peak-load type, such as an electric car, for instance, to discharge a low-power output of long duration and a high-power output of short duration. In an electric device of the constant-load type, the electrical power is supplied by an electrical two-film capacitor (1) and is stabilised to a constant voltage by a switched-mode regulator (2), and a power supply is connected for an electric device of the peak-load type by connecting a first electrical two-film capacitor of the high power density type to a second electrical two-film capacitor of the high power density type, via a switched-mode regulator of the current output type, the second capacitor being charged with electrical power in the first capacitor via the switched-mode regulator. The output power is always drawn from the second capacitor with a high power density.

摘要： PURPOSE:To make uniform the voltage being born by each capacitor in a short time while minimizing the leak current of voltage division resistors. CONSTITUTION:When a specific charging power supply V1 is connected across a charging means comprising a series connection of a plurality of capacitors C1, C2, each capacitor C1, C2 is connected in parallel with a smoothing (voltage dividing) resistor R1, R2 through a switching means SW1, SW2. The switch means SW1, SW2 are turned ON when the charging voltage being fed from the charging power supply V1 is varying. When the charging voltage is not varying and the charging means is performing a voltage holding operation, the switch means SW1, SW2 are turned OFF to make uniform the voltage being born by each capacitor C1, C2.

摘要： PURPOSE:To obtain a solid electrolytic capacitor having small leakage current and stable performance by disposing the mounting position of a negative lead terminal on a conductor layer disposed substantially perpendicularly to the bonded part of an anode foil to a positive lead terminal. CONSTITUTION:The mounting position of a negative lead terminal is disposed on a conductor layer disposed substantially perpendicularly to the bonded part an anode foil to a positive lead terminal. That is, since the anode foil used for an aluminum electrolytic capacitor is generally thin of several tens of microns, the foil is flexible. When it is used in combination with solid electrolyte, a leakage current is increased even by a small impact during manufacturing. Accordingly, the mounting position of the lead terminal is specified at a position which is stronger than the other part to remove its disadvantage, thereby reducing the leakage current. Thus, a solid electrolytic capacitor having small leakage current by the use of the conductive polymer compound as solid electrolyte and stable performance can be obtained.

摘要： PURPOSE:To obtain high capacity, low equivalent series resistance and low leakage current by so coating in advance with a dielectric oxide film without loss of conductivity with polymer compound, and forming conductive polymer compound thereon. CONSTITUTION:In a solid electrolytic capacitor having conductive polymer compound on a dielectric oxide film, a dielectric oxide film coats in advance without loss of conductivity with polymer compound, and a conductive polymer compound is formed thereon. For example, an aluminum anode foil in which the dielectric oxide film is formed on the surface by compounding is coated with ethanol solution of copolymer of sulfonic acid-containing p-fluorovinyl ether and tetrafluoroethylene as polymer compound, and then dried. Aqueous solution containing 0.2mol/l of pyrrole and 0.1mol/l of naphthalene sulfonic acid is employed as electrolyte, it is electrolytically decomposed in 0.5mA/cm of current density for 2 hours with a platinum plate as a cathode, and recompounded with adipic acid compounding solution after the reaction is finished.

摘要： PURPOSE:To obtain a nonaqueous electrolytic capacitor having a low resistance characteristic without damaging a stability by using a specific mixed solvent as a polar solvent for an electrolyte. CONSTITUTION:A tetramethylammonium phthalate salt or a tetraethylammonium phosphate salt is used as a solute. An electrolyte, for-driving use, using a mixed solvent composed of at least one kind selected from tetrahydrofuran, dimethoxyethane, dimethylsulfoxide, methyl cellosolve, dimethylformamide and methyl ethyl ketone and of gamma-buthyrolactone as a solvent for the electrolyte is used. A content of the solute in the solvent is preferably 5 to 40 weight% in the electrolyte. When it is especially 10 to 30 weight%, it is desirable from a viewpoint of a corrosion resistance and a high-frequency characteristic of an electrolytic capacitor.
