Abstract: A method for driving an internal combustion engine is a method for reducing nitrogen oxides in emissions of the internal combustion engine, and includes a process of introducing air, which has a low oxygen concentration and contains no emissions, into the internal combustion engine, and a process of mixing humidifying water with a hydrocarbon fuel and injecting the mixture into a combustion chamber of the internal combustion engine as an emulsion fuel.

Abstract: Provided are a method for reducing a nitrogen oxide in an exhaust gas from an internal combustion engine, a membrane module, an apparatus for reducing a nitrogen oxide from an internal combustion engine using the membrane module, and an internal combustion engine apparatus. A method for reducing a nitrogen oxide in an exhaust gas from an internal combustion engine, the method comprising: a step of bringing pressurized air into contact with one surface of a steam permeable membrane (11), and allowing water to flow along the other surface of the steam permeable membrane (11) to moisturize the pressurized air; and a step of introducing the moisturized air into the internal combustion engine.

Abstract: A main object is to provide a method, a membrane module and a purified water manufacturing device that demonstrate a performance of manufacturing water stably for a long period of time and lower a salt concentration in purified water. In the method, raw water is made to flow along one surface of a gas-permeable membrane, vapor permeated through the gas-permeable membrane is condensed, and the purified water is obtained.

Abstract: The invention aims at finding a highly-safe natural product having glutathione production-enhancing activity, and providing a glutathione production enhancer and a prophylactic/therapeutic agent for diseases caused by glutathione deficiency using that natural product as an active ingredient. The glutathione production enhancer or the prophylactic/therapeutic agent for diseases caused by glutathione deficiency contains, as an active ingredient, a licorice extract composition that contains liquiritin, liquiritigenin, isoliquiritin and isoliquiritigenin but contains substantially no glycyrrhizic acid.

Abstract: A lens holder includes: a first barrel with a plurality of helicoidal grooves that extend from a base portion to an end portion and at positions with rotational symmetry; and a second barrel with a plurality of protrusions that respectively enter the plurality of helicoidal grooves. The helicoidal grooves are respectively divided into helicoidal groove sections in multiple stages with a helicoidal groove section on a base portion side and a helicoidal groove section on an end portion side being disposed at angles that do not overlap. The first barrel includes circumferential grooves on the middle portion and circumferential grooves on the end portion. The middle circumferential grooves connect the end on the end side of the helicoidal groove sections on the base side to the end on the base side of the helicoidal groove sections on the end side and guide the protrusions in the circumferential direction.

Abstract: A separation membrane module for separating a specific component from a mixture containing a plurality of components includes a plurality of separation stages each including a plurality of hollow fiber membranes arranged in parallel to each other. The separation stages are connected in series via connection portions allowing passage of the mixture. At lease one parameter relating to separation by the hollow fiber membrane or membranes in each separation stage is determined to provide effective separation throughout the separation stages.

Abstract: To provide a method of reducing a nitrogen oxide in an exhaust gas of an internal combustion engine, an apparatus for reducing a nitrogen oxide, and an internal combustion engine system that can effectively reduce a nitrogen oxide in the exhaust gas of the internal combustion engine in a simple manner. A method of reducing a nitrogen oxide in an exhaust gas of an internal combustion engine includes: a step of moisturizing air at a pressure equal to or lower than atmospheric pressure by bringing the air into contact with one surface of a steam permeable membrane (11) while flowing water along the other surface of the steam permeable membrane (11); and a step of introducing the moisturized air into the internal combustion engine.

Abstract: There is disclosed a woody thermoplastic resin composition which prevents the occurrence of rust on the metal surface in a molding machine and suppresses the generation of a volatile substance as encountered when a woody thermoplastic resin composed of a thermoplastic resin and wood flour was subjected to heat molding and processing. According to the present invention, a specific amount of dolomite is added to a woody thermoplastic resin composed of a thermoplastic resin and wood flour thereby there may be obtained a woody thermoplastic resin composition which has an effect to prevent the occurrence of rust on the metal surface in a molding machine during the molding and processing and to suppress the generation of a volatile substance.

Abstract: A stopper piece of a regulating member is abutted against a receiving portion formed at a lever of a display mechanism. The stopper is biased in a regulating direction by the force of a torsion coil spring. A projecting piece is abutted against a lever of a releasing member so that the stopper piece can be kept at a position where the rotation of the lever is regulated. The lever of the releasing member is supported in such a manner to move back and forth freely, and is held at the position where the rotation of the lever is regulated before a film pack is set. A trigger plate is formed at the lever. When a pack main body is set at a final position, the trigger plate is pushed by a pack main body and move. When the trigger plate is moved, the lever pushes a lock lever so that the regulation of the lever's rotation by the stopper can be released.
