    Abstract: PROBLEM TO BE SOLVED: To provide a water producing apparatus which easily, quickly, and reliably produces drinking water and water for household use even in a site where water supply is not available and make the apparatus light weight, compact, and economical by installing an electric motor using a storage battery as an electric power source, a raw water pump employing the electric motor as a driving source, and a separation membrane module unit. SOLUTION: A cable 22 is connected with a storage battery 21 of a vehicle 40, a strainer 1 connected with a raw water hose 3 is placed in a lake or a marsh or a river, a prime motor of the vehicle 40 is started, a raw water pump 7 is driven by an electric motor 6, and water is sent to a prefilter 9 through the strainer 1. The water is pre-treated to remove SS components and sent to a reverse osmosis membrane module unit 11 to remove dissolved, components such as salts, trihalomethane, and the likes contained in the water passed through the unit. A part of the obtained water is discharged to outside through a concentrated water distributing pipe 12 to be used for household use. The remaining water is sent to an aspirator 17 after being passed through a filtered water distributing pipe 14, a soluble disinfectant in a disinfectant bottle 20 is added to water when the water flows by, and the water is disinfected and discharged as drinking water to outside.

    Abstract: PURPOSE:To stabilize membrane properties, in preparing a composite membrane for reverse osmosis, by permitting a definite amount of an org. solvent for a porous support present in a membrane forming solution and/or water contained in said porous support. CONSTITUTION:In preparing a composite membrane for reverse osmosis by a method wherein a membrane forming solution (pref., a monomer coating polymerizable solution consisting of, for example, furfuryl alcohol, isocyanuric acid and sulfuric acid as a catalyst) is coated on a porous support comprising porous polysulfone or the like in a wet state and heat treatment is subsequently carried out at 100-170 deg.C, an org. solvent for said support (DMF or DMSO) is made present in a range shown by a formula 0.1

    Abstract: PROBLEM TO BE SOLVED: To obtain a polyolefin-based foam having good whiteness without generating environmental health problems by maintaining and stabilizing whiteness and overcoming polymer degradation caused by high-temperature treatments. SOLUTION: In a sheet polyolefin-based crosslinked foam, a composite blowing agent of azodicarbonamide (A) and N,N'-dinitrosopentamethylenetetramine (B) blended in a ratio of (B)/[(A)+(B)] of 0.1-5 is concurrently used together with a mixed heat stabilizer of a hindered phenol-based and a thio-based stabilizers.

    Abstract: PROBLEM TO BE SOLVED: To obtain a resin composition for foaming and which is excellent in formability, mechanical strength, elongation, thermal stability, or the like, and to provide a foamed body therefrom. SOLUTION: A crosslinked polypropylene-based foamed resin composition comprises 1-10 pts.wt. of a bifunctional vinyl group-containing benzene compound (c) which has a content (M) of a benzene compound having a vinyl group located at a para position of 0.18-0.69, 0.5-5 pts.wt. of an alkyl group and monofunctional vinyl group-containing benzene compound (d) and 1-10 pts.wt. of a thermally decomposable chemical foaming agent per 100 pts.wt. as the sum of 50-90 wt.% of a polypropylene resin (a) having an MFR of 0.5-10 g/10 min. and 10-50 wt.% of a polyethylene-based resin (b) having an MFR of 1-30 g/10 min.
