Abstract: A natural gas liquefying apparatus includes: a precooling unit, which is a treatment unit configured to precool natural gas; a liquefying unit, which is a treatment unit configured to liquefy the natural gas; a refrigerant cooling unit, which is a treatment unit configured to cool a liquefying refrigerant; a compression unit configured to compress vaporized refrigerants; and a pipe rack including air-cooled coolers arrayed and arranged on an upper surface. The treatment units and the compression unit are separately arranged in a first arrangement region and a second arrangement region arranged opposed to each other across a long side of the pipe rack. The pipe rack interposed between the first and second arrangement regions has a region in which no air-cooled cooler is arranged in order to arrange a plurality of pipes, through which refrigerants are allowed to flow, in a direction of a short side of the pipe rack.

Abstract: A fiber sizing agent is described, which is capable of imparting sufficient sizing properties and fiber spreading properties to reinforced fiber bundles for producing fiber-reinforced composite materials. A fiber sizing agent composition (E) includes a sizing agent (A) having a viscosity of 50 to 3,000 Pa·s at 35° C., and has a thixotropic index of 3 to 15. The sizing agent (A) is preferably an epoxy resin, a polyester resin, a polyurethane resin, a polyether resin or a vinyl ester resin.

Abstract: A sizing agent for fibers is provided, which contains a polyester resin, and is capable of improving the emulsification stability and the sizing property while maintaining adhesive property with a matrix resin. The sizing agent for fibers is an aqueous solution or an aqueous emulsion, which contains a polyester resin (A) that satisfies all the following conditions (i)-(iv) and an aqueous medium: (i) that the polyester resin (A) is made from a dicarboxylic acid or its anhydride (a) and diols (b); (ii) that at least one of the diols (b) is diol (b1) that has an average 4.5-60 contiguous oxyethylene groups; (iii) that the weight percentage of the average 4.5-60 contiguous oxyethylene groups in the polyester resin (A) is 25-50 wt %; and (iv) that a mixture of 10 parts by weight of the polyester resin (A) and 90 parts by weight of water forms an uniform transparent solution or an uniform emulsion at 25° C.

Abstract: An object of the present invention is to provide a vehicle which is capable of recycling contaminated liquid in a factory or the like swiftly and efficiently without performing incineration.

Abstract: The present invention uses a curable resin which has: in the molecule thereof, at least two crosslinking functional groups of at least one kind selected from the group consisting of epoxy group, (meth)acryloyl group, alkenylamino group and alkenyloxy group; a glass transition temperature before curing of 50 to 150° C.; a weight-average molecular weight of 10,000 to 1,000,000; and a dielectric constant of not higher than 3.5 after curing. By use of the curable resin of the above constitution, the present invention can provide a curable resin that an insulator having an excellent thermal shock resistance and an excellent dielectric property is obtained.
