    摘要: An RTV organopolysiloxane composition is provided comprising (A) an organopolysiloxane having the formula: HO(R12SiO)xH wherein R1 is a monovalent hydrocarbon group and x is an integer of at least 10, (B) an alkoxysilane compound having on the average at least two silicon-bonded hydrolyzable groups and/or a partial hydrolyzate thereof, (C) organoxy titanium, and (D) an organic compound having at least one hydroxyl group bonded to a benzene ring. The color of the composition tinted with components (C) and (D) fades or changes upon curing of the composition, by which a degree of curing is visually observable. The composition has improved storage stability and resin adhesion.

    摘要: A silicone rubber composition for use in rubber construction materials contains dispersed particles having a photocatalytic activity. The particles are surface-treated with a compound that can easily be deteriorated by the photocatalytic activity under outdoor exposure to ultraviolet light. Rubber construction materials made of the cured form of the composition, when exposed to ultraviolet light, undergo surface hydrophilization that endows them with excellent stain resistance, and also have excellent sealing properties. When the composition is applied as a coating, filled into joints, or used as a solid gasket, it does not cause staining of the building, joints, or the area around joints.

    摘要: A method for producing D-lactic acid in high yield, and to provide a method for producing D-lactic acid with high selectivity, in which optical purity is high and a by-product organic acid is small. In one aspect, a microorganism, wherein activity of pyruvate formate-lyase (pfl) is inactivated or decreased, and further activity of Escherichia coli-derived NADH-dependent D-lactate dehydrogenase (ldhA) is enhanced, is cultured to efficiently produce D-lactic acid. With regard to a method for enhancing ldhA activity, by linking, on a genome, a gene encoding ldhA with a promoter of a gene which controls expression of a protein involved in a glycolytic pathway, a nucleic acid biosynthesis pathway or an amino acid biosynthesis pathway, suitable results are obtained compared to the method for enhancing expression of the gene using an expression vector. A microorganism in which a dld gene is substantially inactivated or decreased is cultured to produce high quality D-lactic acid with reduced concentration of pyruvic acid.

    摘要: An image extraction device for extracting an image showing a document from an image of the document shot by an imaging device includes a document table on which a document is placed, a side detection unit, an opposing side estimator, and an image extraction unit. The side detection unit detects a side of the document on the document table based on the shot image of the document. The opposing side estimator estimates a position of a side opposite the side detected by the side detection unit. The image extraction unit segments the image of the document from the shot image of the document based on the side detected by the side detection unit and the opposite side estimated by the opposing side estimator.
