Abstract: Black currant anthocyanin-containing compositions for foods comprising 1 to 25% by weight of black currant anthocyanin on the basis of solid matters; a process for producing a black currant anthocyanin-containing composition for foods characterized by purifying and concentrating black currant juice employed as a starting material by using a charged reverse osmosis membrane; functional foods and drinks characterized by containing the above compositions for foods; and the above-described compositions for foods and the above-described functional foods and drinks having an effect of improving visual function, a function of improving blood fluidity, and/or a function of lowering blood pressure. The conventional black currant anthocyanin compositions have a low black currant anthocyanin content, strong acidity and poor stability, which makes them unsuitable as additives for foods and drinks.

Abstract: A polishing pad for electrolytically polishing an interconnect material of a device wafer by applying a direct-current voltage to the interconnect material as an anode and a cathode as a counter electrode while causing an electrolyte to come in contact with the anode and the cathode, the polishing pad includes a plurality of electrolytic cells formed by the anode, the cathode, and the electrolyte and having a contact surface smaller than the device wafer, the electrolytic cells being moved relative to the interconnect material when electrolytically polishing the interconnect material on the device wafer.

Abstract: A polishing pad for use in chemical mechanical polishing is formed of silicone rubber. An abrasive fine inorganic powder and a reinforcing fine silica powder are dispersed in the silicone rubber, and the inorganic powder has a particle size of 0.01-100 &mgr;m and is contained in the amount of 10-85 wt.% of the silicone rubber.

Abstract: An abrasive fine inorganic powder is dispersed in silicone rubber to confer adequate wet strength and chemical resistance.

Abstract: An object of the present invention is to provide a polishing pad capable of obtaining the stabilized polishing performance and a method for manufacturing the same.

Abstract: A process for delivering the orally administered active ingredients which are safe even in their successive administrations for a long period to the large intestine without elution of the ingredients before reaching the large intestine is disclosed. The process according to the present invention comprises a step of administering orally to animals including human a composite comprising a core containing the active ingredients, an internal layer comprising chitosan with which the core is coated, and an external layer comprising a gastric acid resistant material with which the internal layer is coated, wherein all of the materials in the composite have the empirically established safety to humans. When a material having an iron cation scavenging ability, particularly phytin is used as the active ingredient, it is possible to treat colon cancer efficiently by the process according to the present invention.

Abstract: A pulverized coal combustion apparatus comprises a burner through which pulverized coal and carrier air are passed to be burnt in a combustion chamber, and a flame retainer disposed at an end of the burner. The flame retainer includes a flared tube and an annular plate, which plate has a plurality of radially inwardly projecting parts equiangularly spaced from each other. The annular plate comprises a plurality of ceramic pieces and a plurality of fastener elements, both of which are arranged and assembled alternately to form the annular plate. Each ceramic piece is so shaped that it projects radially inwardly to serve as the projecting part when assembled. The ceramic piece has at opposite sides thereof smoothly curved edge surfaces, and the fastener element has at opposite sides thereof smoothly curved edge surfaces which are engaged with the curved edge surfaces of neighboring two ceramic pieces.
