Abstract: A thrust race of a thrust roller bearing has a race portion and a cylindrical portion extending from the race portion in an axial direction. At a plurality of locations along a circumferential direction on the cylindrical portion, cutout portions are formed such that each of the cutout portions is recessed in the axial direction from a distal edge of the cylindrical portion toward the race portion. A protrusion is provided at a portion closer to the race portion from a bottom edge of each of the cutout portions such that the protrusion protrudes in a radial direction from the cylindrical portion toward a side away from the race portion. The protrusion serves as a race-retaining locking portion to prevent a race from moving out from a mating member on which the race is mounted.

Abstract: The present invention provides an apparatus including a compound database which has been produced by extracting fingerprints of compound related to plural atoms in a compound for each candidate compound, characterized by extracting the fingerprints of compound of binding compounds that are already known to bind to family proteins having 3-dimensional structure that is identical or similar to that of target protein, together with the 3-dimensional coordinates that have been converted into the coordinate system of the target protein, to produce a fingerprint set of binding compound, and for a candidate compound stored in the compound database, computing the 3-dimensional structure of the candidate compound with respect to the target protein, so that the interaction score based on the root-mean-square deviation of a unit of fingerprint of compound calculated on the basis of the 3-dimensional coordinates of the fingerprint set of binding compound is optimized.

Abstract: An apparatus for processing 3-dimensional structure of protein includes a control unit and a storage unit, wherein the storage unit stores 3-dimensional structure information of protein, and the control unit predicts 3-dimensional structure information of protein after the mutation when an arbitrary amino acid residue A in the 3-dimensional structure information of protein stored in the storage unit is mutated into another amino acid residue a, thereof from the 3-dimensional structure information of protein before and after the mutation, collects the amino acid residue A, the amino acid residue a, environment information P, and environment information p, which are related to each other, as information on environmental change, when the environment information P around the amino acid residue A before the mutation changes to the environment information p around the amino acid residue a after the mutation, thereby storing information on the environmental change in the storage unit.

Abstract: A rubber composition for a tire tread which is provided by the present invention can be obtained by blending 100 parts by weight of a natural rubber and/or a diene synthetic rubber with40 to 100 parts by weight of a carbon black having characteristic values of a cetyltriammonium bromide adsorption specific surface area (CTAB) being 90 to 220 m.sup.2 /g and a 24M4DBP absorption value being 90 to 140 ml/100 g, and0.1 to 20 parts by weight of an organic unsaturated fatty acid having two or more carbon double bonds in its molecule which includes 10% by weight or more of a conjugated diene acid having at least one pair of two carbon double bonds in a conjugated relation in its molecule.This rubber composition for a tire tread can be suitably used for a pneumatic tire, particularly a pneumatic tire for heavy load having an excellent wear resistance.

Abstract: This invention aims at providing a novel semiconductor accelerometer comprising a smaller number of substrates and a production method thereof.An insulating film is formed on a main plane of a P-type silicon substrate, and a beam-like movable electrode is formed on the insulating film. Fixed electrodes are then formed on both sides of the movable electrode in self-alignment with the movable electrode by diffusing an impurity into the P-type silicon substrate, and the insulating film below the movable electrode is etched and removed. There is thus produced a semiconductor accelerometer comprising the P-type silicon substrate 1, the movable electrode 4 having the beam structure and disposed above the P-type silicon substrate 1 with a predetermined gap between them, and the fixed electrodes 8, 9 consisting of the impurity diffusion layer and formed on both sides of the movable electrode 4 on the P-type silicon substrate 1 in self-alignment with the movable electrode 4.
