Abstract: An injection moldable fluorine-containing meltable resin composition comprising 70 to 98 wt. % of a fluorine-containing meltable resin, and 2 to 30 wt. % of a needle-shape material having an average diameter of 3 &mgr;m or less, an average aspect ratio of between 10 and 100, and Mohs hardness of between 5 and 8, which composition has good sliding and sealing properties and excellent moldability, in particular, moldability of thin wall articles.

Abstract: A method of manufacturing a simulated wood product which has not only a texture similar to wood, but also exhibits a pattern similar to the grain of natural wood depending on molding conditions, and such a simulated wood product itself. Specifically, pulverized dust 102 obtained by pulverizing a cellulose material as raw materials is subjected to a trituration process to produce powdery particles 111, 121 having an increased bulk specific gravity, surface particles 112, 122 smaller in size and harder than the powdery particles are fixed to outer circumferential surfaces of the powdery particles to produce fixed particles 110, 120, a resin and a pigment are mixed with the fixed particles, and a resultant mixture is melted to be later or simultaneously molded into the desired shape by extrusion or injection molding.

Abstract: A process is disclosed in which an amino acid-producing microorganism having an ability to assimilate lactic acid is aerobically cultivated in the presence of at least one lactic acid microorganism in an aqueous nutrient medium containing at least one carbohydrate which is assimilable by the lactic acid microorganism but nonassimilable or weakly assimilable by the amino acid-producing microorganism as the main carbon source and an accumulated amino acid is recovered from the culture broth. An industrially advantageous production of an amino acid has become feasible by utilizing inexpensive carbon sources or those organic substances in agricultural or livestock wastes that have heretofore not been effectively utilized.
