Abstract: A color filter is manufactured on each of a plurality of light-receiving elements of an RGB sensor using a plurality of kinds of light-transmitting films having different transmission colors. In such a case, the light-transmitting film that is to be coated next does not uniformly spread across the entire semiconductor wafer, and coating nonuniformities readily occur when a pattern of the light-transmitting film formed earlier on a certain optical element has a right angle portion. In order to solve this problem, the pattern of the light-transmitting film formed earlier has a planar shape having corner-cut portions so that right angle portions do not occur.

Abstract: It is an object of the present invention to provide a durability improving agent for a cement composition that improves the freezing-thawing resistance of the cement composition and also exhibits a sufficient shrinkage reducing performance as well, and a cement composition including such a durability improving agent. Specifically, the present invention provides a durability improving agent for a cement composition, characterized by comprising a hydrocarbon-based compound having an average molecular weight of 150 to 600 and a pour point of 20° C. or less as an active ingredient, and a cement composition including such durability improving agent.

Abstract: There is here provided a wing-like needle protector which can surely prevent mistaken sticking, and can safely cap a hollow needle. The wing-like needle protector for housing a wing-like needle 1 which comprises a hollow needle 2, a holding cylinder 3 for holding a rear end of the hollow needle 2, and a pair of wing pieces 4, 4 formed integrally with the holding cylinder 3 so as to freely coalesce with each other. The protector comprises a gutter-shaped member 7 for housing the hollow needle 2, the holding cylinder 3 and the coalesced wing pieces 4, 4, and a gripper 8 protruded outward from a bottom surface of the gutter-shaped member 7. The gutter-shaped member 7 has a closed tip 9a of a portion 9 for housing the hollow needle 2, an opened rear end 10a of a portion 10 for housing the holding cylinder 3, and a narrowed area 7a where the holding cylinder 3 is fitted in a bottom portion, and the holding cylinder 3 is engaged with the narrowed area 7a.

Abstract: A process for hydrogenating acetylene in hydrogen chloride gas using the catalytic palladium supported on silicon carbide carrier whose iron content is specified to be not more than 1,000 ppm. The catalyst has the advantages of enhancing the conversion of acetylene into ethylene, improving the selectivity of ethylene, and retaining catalytic activity over a long time at a large space velocity. This process can be effectively applied to the hydrogenation of acetylene in hydrogen chloride gas separated from the thermally decomposed products of 1,2-dichloroethane which occurs in the production of vinyl chloride; namely, the hydrogen chloride gas that contains thus hydrogenated acetylene (ethylene) can be recycled in such an effective way that 1,2-dichloroethane can be produced economically.
