  • Patent number: 5948329
    Abstract: It is possible to obtain at high yield a carbonaceous material suitable for carbon electrodes of electrical double layer capacitors and having superior capacitance by means of a method comprising a halogenation treatment step wherein a halogenated dry-distilled charcoal is obtained by bringing a dry-distilled charcoal into contact with a halogen gas; and by a dehalogenation treatment step wherein a part or all of the above-mentioned halogen in said halogenated dry-distilled charcoal is eliminated. In addition, it is possible to obtain carbonaceous material for electrical double layer capacitors, which has a large capacitance at rapid discharge and excellent shape, by means of conducting a molding treatment step in which a molded article is made by crushing a dry-distilled charcoal and adding a binding agent; and a carbonization treatment step in which the above-mentioned molded article is heated in an inert gas atmosphere before conducting the halogenation treatment.

  • Patent number: 5149308
    Abstract: A transmission comprising a change speed mechanism and a differential housed in a transmission case. The change speed mechanism includes drive gears mounted on a transmission shaft, and driven gears meshed with drive gears. The differential includes a differential case having elongated axle-bearing bosses extending to inside walls of the transmission case. The driven gears are mounted on one of the elongated bosses to be rotatable therewith. The differential case is supported by rear wheel axles extending through the transmission case and the elongated bosses.

  • Patent number: 4473527
    Abstract: In the manufacture of an inflation film for forming a thermoplastic resin having a melt tension of not more than 4 g into a tubular bubble, a tubular bubble extruded from an extruding nozzle is cooled from the inner circumferential surface thereof by air supplied from a first air supply opening. The outer circumferential surface of the bubble is cooled with air from a first external air-cooling ring arranged at the outside of the bubble. The first air-cooling ring has a guide plate for guiding the bubble, a second air supply opening for supplying air between the guide plate and the bubble from an inlet port arranged at the lower end of the guide plate, and a third air supply opening for supplying air to the bubble from an outlet port arranged at the upper end of the guide plate. The bubble which is cooled by the first external air-cooling ring is further cooled by the air supplied from a second external air-cooling ring. The bubble is solidified.

  • Patent number: 4171054
    Abstract: A work vehicle having a work arm assembly mounted for horizontal oscillation on a swivel platform. The arm assembly and the swivel platform are actuated by separate hydraulic actuators. The two actuators are connected in parallel with one another to a control valve via a circuit selection valve. The arrangement enables the swivel platform and the arm assembly to move in the same direction by operating the control valve.
