    摘要： Provided are a pitch-formation suppressor and the like which can be widely applied independently of the substance that causes a pitch and of the situation to generate a pitch in a paper manufacturing process, and which can effectively suppress and prevent the troubles due to the pitch, such as foreign spots and defects in a paper, breakage of a paper, and lowering of workability. This pitch-formation suppressor comprises an alkaline solution in which a phenol resin and/or a modified phenol resin is dissolved, or an acid solution in which a phenol resin and/or a modified phenol resin is dissolved.

    摘要： An object of the present invention is to provide a material which resolves the drawbacks associated with polyimide polymers, and yet retains the advantages offered by conventional polyimide polymers. An amino group containing phenol derivative of the present invention is represented by a general formula (1) show below, and the present invention also provides a polyimide precursor produced using such an amino group containing phenol derivative. 1 (wherein, R1, R2 and R3, which may be the same or different, each represent an alkyl group of 1 to 9 carbon atoms, an alkoxy group of 1 to 10 carbon atoms, a COOR group (in which R represents an alkyl group of 1 to 6 carbon atoms) or a hydrogen atom; R4 and R5, which may be the same or different, each represent an alkyl group of 1 to 9 carbon atoms or a hydrogen atom; X represents nullOnull, nullSnull, nullSO2null, nullC(CH3)2null, nullCH2null, nullC(CH3)(C2H5)null, or nullC(CF3)2null; and n represents an integer of 1 or greater).

    摘要： The resin-coated sand is produced by coating the surface of a refractory granular aggregate with a thermosetting resin and a thermoplastic resin. When using this resin-coated sand, a mold with a less rough surface can be produced by a RP molding apparatus. When using this mold made of the resin-coated sand, a casting with fewer gas defects can be produced.
