  • Patent number: 8352139
    Abstract: An apparatus comprises a changeover mechanism which is able to change a connection state of an electric motor output shaft to any one of “an IN-Connection State” in which a power transmission path is provided between a transmission input shaft and the electric motor output shaft, “an OUT-Connection State” in which a power transmission path is provided between the transmission output shaft and the electric motor output shaft, and “a neutral state” in which no transmission path therebetween is provided. When a kick-down-condition is satisfied, a changeover operation for changing an electric motor connection state to the OUT-Connection State is firstly performed. Thereafter, a gear position shifting operation for increasing a transmission reduction ratio is performed. After the kick-down-condition satisfied, an E/G side output torque Te and a M/G side output torque Tm is adjusted in such a manner that a sum Ts of Te and Tm continues to increase.

  • Patent number: 8343348
    Abstract: A method for producing a carbon membrane of the present invention is a production method where a carbon membrane obtained by subjecting a carbon-containing layer to thermal decomposition in an oxygen inert atmosphere while sending a gas mixture containing an oxidizing gas thereinto is thermally heated. The carbon membrane is subjected to a heating oxidation treatment with controlling the ratio of the flow rate of the gas mixture to the areas of the carbon membrane to 0.5 cm/min. or more to control (temperature ° C.)2×time (h)/10000, which is the relation between the temperature of the gas mixture and the flow time, to 9 to 32. This enables to obtain a carbon film which selectively separates alcohols having 2 or less carbon atoms from a liquid mixture of the alcohols having 2 or less carbon atoms and organic compounds having 5 to 9 carbon atoms.

  • Patent number: 8343431
    Abstract: The honeycomb filter is constructed as a diesel particulate filter having a filtration function for filtering out the particulate matter included in an exhaust emission of a diesel engine. The honeycomb filter has a honeycomb structure as a base and inlet opening cells with surface layers formed on respective inner surfaces thereof. The surface layer has zero film thickness in an inlet peripheral region. Separation vortexes are generated in the inlet peripheral regions. The zero film thickness of the surface layers in the inlet peripheral regions naturally causes non-flaking of the surface layers induced by the separation vortexes generated in the inlet peripheral regions and thereby leads to non-production of flakes. In the non-existent condition of flakes, the overall surface layers are not collapsed by collision of the flakes.
