摘要： PURPOSE:To easily obtain the title formed product of high reaction efficiency by homogeneously mixing an aqueous polymer solution with a dispersion containing a specified amount of a nonionic fatty acid ester with microoganisms dispersed into separate individuals and by coagulating the resultant mixture. CONSTITUTION:A nonionic fatty acid ester (e.g. sorbitan monostearate) is dissolved in water, and the resultant solution is gradually added, while stirring, to an aqueous microorganism solution so as to be 0.001-2wt.% in the concentration of the former solution (based on the concentration of suspended matter as the microorganisms) into a dispersion with the microorganisms dispersed into separate individuals. Thence, this dispersion is homogeneously mixed with an aqueous solution of a polymer (e.g. PVA). The resulting mixture is then coagulated by e.g. introduction into a coagulating solution (e.g. an aqueous sodium sulfate solution), thus obtaining the objective formed product made up of (A) the microorganisms, (B) the polymer and (C) 0.001-2wt.%, based on the microorganisms, of the nonionic fatty acid ester.

摘要： PURPOSE:To easily obtain a large amount of immobilized biocatalyst consisting of spherical gel and having high activity by dropping a liquid mixture of an aqueous solution of polyvinyl alcohol, an aqueous solution of a gelatinizable water-soluble polymeric polysaccharide and a biocatalyst into a coagulation liquid to effect the coagulation of the components, separating the coagulum from the liquid and freezing and then thawing the product. CONSTITUTION:The objective immobilized biocatalyst is formed by the following steps A to G. (A) A step to dissolve polyvinyl alcohol; (B) a step to dissolve a water-soluble polymeric polysaccharide gelatinizable by contacting with at least one kind of cation; (C) a step to mix the aqueous solution of polyvinyl alcohol, the aqueous solution of the above watersoluble polymeric polysaccharide and a biocatalyst; (D) a dropping step; (E) a coagulation step; (F) a liquid remov ing step and (G) a freezing and thawing step.

摘要： PURPOSE:To improve the stability of shape at the time of using by using heat resistance aromatic polyamide fiber specifying melting point, exothermic starting temp., crystallized degree and dry heat shrinkage ratio to a spacer for heat treatment. CONSTITUTION:The spacer to be used for the heat treatment of aluminum products is formed by using the aromatic polyamide fiber satisfying conditions in the inequalities I-VI. Wherein, Tm: the melting point, Tex: the exothermic starting temp., Xc: the crystallized degree, DE: elongation degree, Dsr(Tm): the dry heat shrinkage ratio at the melting point, Tm, and Dsr(Tm+55 deg.C): the dry heat shrinkage ratio at the melting point +55 deg.C. Needle felt, etc. is made by using this heat resistant fiber and the spacer is formed by compressing and heat-treating. The polyamide fiber is desirable to produce from the aromatic polyamide having functional group selected among lower alkyl group, amino group, sulfone group, carbonyl group, hydroxyl group, having 1-4 of carbon atoms. in ortho position of phenylene group directly coupling with nitrogen atom. and carbon atom. in amide coupling or halogen atom.

摘要： PURPOSE: To achieve a higher durability of a ball by producing a sewing thread of a fiber obtained by melt-spinning a wholly aromatic polyester. CONSTITUTION: A thermotropic liquid crystal polymer comprising a copolymer of p-hydroxybenzoic acid and 6-hydroxy-2-naphthoic acid is used to be melt-spun by adding a red pigment thereto. The spun raw yarn obtained is doubled to make a tow for the production of a spun yarn by a normal tow spinning method. Moreover, the spun yarn obtained undergoes a thermal treatment in the air and twisted to make a sewing thread. This achieves a higher durability of a ball as compared with the sewing thread produced from a polyvinyl alcohol- based spun yarn and a Kevlar (R) spun yarn made of an aramid fiber.
