    • A thermoplastic elastomer composition powder comprising a thermoplastic elastomer composition represented by the following (A), having a sphere-reduced average diameter of not more than 1.2 mm and a bulk specific gravity of not less than 0.38: (A) a thermoplastic elastomer composition comprising (a) 100 parts by weight of a polyolefin resin; (b) 20 to 250 parts by weight of a conjugated diene polymer of hydrogenated conjugated diene copolymer having a hydrogenation degree of not less than 70%, which is prepared by hydrogenating a conjugated diene-vinyl aromatic compound random copolymer in which the content of a vinyl aromatic compound unit is not more than 25% by weight; and (c) 0 to 500 parts by weight of an ethylene/&agr;-olefin copolymer rubber. This powder can give a molded article having excellent appearance and flexibility, which does not cause whitening easily on bending, according to the powder molding method.

    • An overhead camshaft structure for a double overhead camshaft engine having at least three in-line cylinders and two camshafts which are formed with series of pairs of cam lobes and series of camshaft journals, respectively, and are operatively connected with each other by helical gears comprises a thrust collar formed on each camshaft, a thrust bearing formed with a thrust restrictive groove consisting of an upper half and a lower half, narrower than the upper half, for receiving therein the thrust collar, and an oil passage consisting of a radial passage portion penetrating through the thrust collar and an axial passage portion formed in each camshaft for allowing oil to pass up to each cam lobe and camshaft journal for lubrication. The radial passage is directed in parallel with a straight line connecting an axial centerline of rotation of each said camshaft and a juncture of a valve opening ramp of said cam lobe adjacent to said thrust collar.
    • 一种用于双顶置凸轮轴发动机的顶置凸轮轴结构,其具有至少三个一字形气缸和两个凸轮轴,其分别由一对凸轮凸角和一系列凸轮轴轴颈形成,并且通过螺旋齿轮彼此可操作地连接, 形成在每个凸轮轴上的止推环,推力轴承,其形成有由上半部和下半部构成的推力限制槽,该上推力限制槽比上半部窄,用于在其中容纳止推轴环;以及油通道,其由径向通道部分 穿过止推环和形成在每个凸轮轴中的轴向通道部分,用于允许油通过每个凸轮凸轮和凸轮轴轴颈以进行润滑。 径向通道与连接每个所述凸轮轴的轴向旋转中心线和所述凸轮凸角的与所述推力环相邻的阀开口斜面的接合点的直线平行地引导。
