    摘要： An electric double layer capacitor excellent in cycle characteristic with which a high electrostatic capacity is obtained by impression of a low voltage is provided. Carbonization treatment is carried out in which 1 kg of meso carbon micro beads whose particle diameter is 25 μm is heated in a nitrogen atmosphere at 800° C. for 2 hours, and is cooled to room temperature. The carbide of meso carbon micro beads and sodium hydroxide powder are mixed in a ratio by weight of 1:2.5. Alkali activation treatment is carried out in which the mixture is heated in a helium atmosphere at 600° C. for 1 hour, and the carbide is exposed to sodium vapor. After cooling to room temperature, 8 g of this carbon powder, 1 g of ketchen black 1 g and 1 g of polytetrafluoroethylene are kneaded and rolled into a sheet 0.5 mm thick. The sheet-like carbon material is stamped out 16 mm in diameter to be active carbon layers 3 which form polarizable electrodes 4 in combination with collecting layers 2. The polarizable electrodes 4 and a separator 1 are combined and impregnated with an organic electrolytic solution to produce an electric double layer capacitor A.

    摘要： Disclosed is a novel fluorocarbon comprising carbon atoms and fluorine atoms and having no double bond, the atomic ratio of fluorine to carbon atoms being 1.50 to 1.93, which exhibits a liquid state at room temperature. The liquid fluorocarbon has excellent water- and oil-repellent properties and can advantageously be used, for example, not only as a water- and oil-repellent but also as an inert liquid, a heat transfer agent and a vapor phase soldering liquid in various fields, especially in the electronic industry. The liquid fluorocarbon can be obtained directly from a pitch or from a pitch fluoride which can be obtained by direct fluorination of a pitch.
