Abstract: There is provided a curable resin composition capable of obtaining a resin molded body that is excellent in wear resistance and has a high flexural modulus. The curable resin composition according to the present invention contains a polyol compound, an isocyanate compound, a long reinforcing fiber, and a filler, in which the specific gravity of the filler is less than 4 and the average circularity of the filler is 0.65 or more.

Abstract: A thermosetting furan resin composition comprising furan based resin (A), curing catalyst (B), and additive (C) that is a normal salt including a strong acid and a strong base is offered. The abovementioned additive (C) preferably has a solubility in water of 30 g/100 g H2O at 20° C. Furthermore, the abovementioned additive (C) is at least one selected from the group consisting of sodium chloride, potassium chloride, lithium chloride, sodium bromide, potassium bromide, lithium bromide, sodium sulfate, potassium sulfate, lithium sulfate, sodium nitrate, potassium nitrate, and lithium nitrate, or a mixture thereof. The content of the abovementioned additive (C) is 0.2-10 parts by weight based on the aforementioned furan based resin (A) being 100 parts by weight.

Abstract: A pharmaceutical preparation for rectal administration by which a drug is retained in the affected region or the lower region of the rectum, where the drug is sustained-released is disclosed. The present invention is a pharmaceutical preparation for rectal administration comprising a coated drug-supported particle dispersed in a base, wherein the coated drug-supported particle is what a drug-supported porous microparticulate carrier is coated with a water-soluble polymer having a certain viscosity.

Abstract: A welding method for two members adapted to be welded and formed of a low-alloy steel for structural purposes causing the weld metal to develop martensite transformation during cooling after welding, so that the weld metal becomes expanded to a greater degree at room temperature than at a temperature at which the martensite transformation initiates. The welding material comprises a ferrous alloy containing C, Cr, Ni, Si, Mn, Mo and Nb, all of which meet substantially with the contents of the following equation (1): 170≦719−(795×C wt %)−(23.7×Cr wt %)−(26.5×Ni wt %)−(35.55×Si wt %)−(13.25×Mn wt %)−(23.7×Mo wt %)−(11.85×Nb wt %)<250  (1).
