  • Patent number: 8707928
    Abstract: A lubrication apparatus for a four-stroke engine that prevents lubrication failure from occurring around the crankshaft and reliably prevents oil from remaining in a valve operating chamber includes: an intake part positioned below the level of an oil A in an oil reservoir even if the oil reservoir is tilted and the level of the oil A changes; an oil feeding passageway that sucks up the oil A from the intake part and supplies the oil A to the crank chamber; and an direct passageway that allows communication between a valve operating chamber and a crank chamber when a negative pressure is created in the crank chamber. Open end parts of the oil feeding passageway and the direct passageway which are open in the crank chamber are provided to open as the piston moves from a position near the top dead center to the top dead center.

  • Patent number: 8637416
    Abstract: There is provided a zeolite membrane which is thinner than a conventional membrane and which has improved permeability and a method for manufacturing the zeolite membrane. The method includes a surface layer forming step for forming a surface layer by attaching a low polar polymer on a first surface of a porous substrate to cover the surface, a filling step for filling a masking polymer into pores in the porous substrate from a surface different from the first surface of the porous substrate up to the surface layer by impregnating the porous substrate with the masking polymer and solidifying the masking polymer, and a surface layer removing step for removing the surface layer. After the surface layer removing step, a zeolite membrane is formed on the first surface of the porous substrate.

  • Patent number: 8263516
    Abstract: A method for manufacturing a DDR zeolite membrane element including the steps of: immersing a porous substrate in a raw material solution, forming a DDR zeolite membrane containing 1-adamanthanamine on a surface of the porous substrate by subjecting a DDR zeolite to hydrothermal synthesis in the presence of DDR zeolite seed crystals, applying a glass paste onto the surface of the porous substrate so as to contact the membrane, and heating the membrane at 500 to 800° C., thereby burning away the 1-adamanthanamine contained in the membrane and melting the glass paste to form a membrane-like glass seal contacting the membrane on the surface of the porous substrate. The method for manufacturing a DDR zeolite membrane element can inhibit the permeation of the DDR zeolite membrane from being hindered in a contact portion between the membrane and the glass seal and inhibit poor seal of the glass seal.
