摘要： A lubrication apparatus for a four-stroke engine (1) is provided that prevents lubrication failure from occurring around the crankshaft and reliably prevents oil from remaining in a valve operating chamber (30). The lubrication apparatus for the four-stroke engine (1) includes: an intake part (55) positioned below the level of an oil A in an oil reservoir (7) even if the oil reservoir (7) is tilted and the level of the oil A changes; an oil feeding passageway (54) that sucks up the oil A from the intake part (55) and supplies the oil A to the crank chamber (5a); and an direct passageway (47) that allows communication between a valve operating chamber (30) and a crank chamber (5a) when a negative pressure is created in the crank chamber (5a). Open end parts (47a, 54a) of the oil feeding passageway (54) and the direct passageway (47) which are open in the crank chamber (5a) are provided to open as the piston (13) moves from a position near the top dead center to the top dead center. It is possible to control the flow rate of oil supplied to the crank chamber (5a) via the oil supply passageway (54) by means of a flow rate control passageway (67) that allows communication between a supply passageway (51) to supply oil mist from the oil reservoir (7) to the valve operating chamber (30) and the oil feeding passageway (54).

摘要： 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.

摘要： A DDR type zeolite membrane formed on a substrate includes silica as a main component. The DDR type zeolite membrane separates at least one type of a gas component from a mixed gas containing at least two types of gases selected from a group consisting of carbon dioxide (CO2), hydrogen (H2), oxygen (O2), nitrogen (N2), methane (CH4), normal butane (n-C4H10), isobutane (i-C4H10), sulfur hexafluoride (SF6), ethane (C2H6), ethylene (C2H4), propane (C3H8), propylene (C3H6), carbon monoxide (CO), and nitrogen monoxide (NO). Each single gas permeance at room temperature and 100° C. are different, respectively, in order to separate at least one selected gas component from the mixed gas.

摘要： A method for producing a zeolite composite membrane in which a zeolite membrane is formed on a porous substrate includes the steps of: coating a zeolite membrane on a porous substrate made of zeolite having the same or a similar composition as the zeolite membrane and containing the same template as the zeolite membrane; and calcining the porous substrate having the zeolite membrane thereon to remove the template from the zeolite membrane and the porous substrate at once. A zeolite composite membrane that does not have cracks can be obtained by almost equalizing thermal expansion coefficients of the porous substrate and the zeolite membrane.
