Abstract: This invention relates to a styrene-based (co)polymer capable of improving tan ? of a rubber composition while ensuring a fracture resistance of the rubber composition by adding to the rubber composition, and more particularly to a styrene-based polymer obtained by homopolymerizing a styrene derivative and having a weight average molecular weight as converted to polystyrene of 2×103 to 50×103, and a styrene-based copolymer obtained by copolymerizing styrene and at least one of styrene derivatives and having a weight average molecular weight as converted to polystyrene of 2×103 to 50×103.

Abstract: This invention relates to a rubber composition having a high storage modulus (G?) and a low loss tangent (tan ?), and more particularly to a rubber composition comprising 2 to 60 parts by mass of a low-molecular weight aromatic vinyl compound-conjugated diene compound copolymer (B) having an aromatic vinyl compound content of 5 to 80% by mass, a vinyl bond content in a conjugated diene compound portion of 5 to 80% by mass, a weight average molecular weight as measured through a gel permeation chromatography and converted to polystyrene of 5,000 to 500,000 and at least one functional group based on 100 parts by mass of a rubber component (A) composed of at least one of natural rubber and synthetic diene-based rubbers.

Abstract: A tail wire cutting method and bonding apparatus executing the same, in which a capillary raised to a predetermined height and a clamper disposed above the capillary and gripping a wire are caused to make reciprocating oscillation movement on, for instance, a circular arc that has an apex at the above-described predetermined height, thus forming (minute) cracks in a portion between the tail wire and a bonding end of a bonding point, and then cutting of a tail wire sticking out of the tip end of the capillary is executed by way of raising the capillary and clamper.

Abstract: A wire bonding apparatus including a bonding control section provided with an electrical non-bonding detector, an optical non-bonding detector, and an optical shape detector, which are for detecting non-bonding between a first bonding point and a bonding wire; and when non-bonding is detected by the electrical non-bonding detector and non-bonding is also detected by the optical non-bonding detector, then the tip end of the bonding wire is reformed by, based on the shape of the tip end of the bonding wire detected by the optical shape detector, a ball formation device into a ball of a prescribed shape, and rebonding is performed at the first bonding point.

Abstract: The object of the present invention is to provide a face wash which effectively removes pore stains and aged horny layers of the skin and gives whitening effect but has lesser stimulant feel. The present invention solves the object by providing a face wash comprising a protein-degrading enzyme, lipid-degrading enzyme, trehalose, D-glucose, and ascorbic acid and/or a derivative thereof as effective ingredients.

Abstract: Novel triazolo derivatives represented by the following formula and pharmaceutically acceptable salts thereof, as well as chemokine inhibitors containing the same as an effective component. These are useful as therapeutic agents for allergic diseases such as bronchial asthma and atopic dermatitis; therapeutic agents for inflammatory diseases such as chronic rheumatoid arthritis; therapeutic agents for autoimmune diseases such as ulcerative colitis and nephritis; and as anti-AIDS drugs.
