    • A tire having a portion formed of a rubber composition which comprises a high-molecular-weight polymer component which contains bound styrene in an amount not greater than 30% by weight, is a styrene-butadiene copolymer or a conjugated diene polymer such as polybutadiene, and has a weight-average molecular weight of at least 30.times.10.sup.4 ; and a low-molecular-weight polymer component which contains bound styrene in an amount not greater than 30% by weight, is a styrene-butadiene copolymer or a conjugated diene polymer such as polybutadiene, and has a weight-average molecular weight of from 0.2.times.10.sup.4 to 8.times.10.sup.4. The rubber composition contains 30 parts by weight of the low-molecular-weight polymer component relative to 100 parts by weight of the high-molecular-weight polymer component. The ratio between the amount of bound styrene and the vinyl linkage content falls within specific ranges. When the vulcanized rubber composition was extracted by chloroform, an amount of the extract is not less than 15% by weight of the low-molecular-weight polymer component.
    • 具有由含有不大于30重量%的结合苯乙烯的高分子量聚合物组分的橡胶组合物形成的部分的轮胎是苯乙烯 - 丁二烯共聚物或共轭二烯聚合物如聚丁二烯, 并且具有至少30×10 14的重均分子量; 含有不大于30重量%的结合苯乙烯的低分子量聚合物组分是苯乙烯 - 丁二烯共聚物或共聚二烯聚合物如聚丁二烯,并且重均分子量为0.2 x104至8x104。 橡胶组合物相对于100重量份的高分子量聚合物组分含有30重量份的低分子量聚合物组分。 结合苯乙烯的量与乙烯基键含量的比例落在特定范围内。 当硫化橡胶组合物用氯仿萃取时,提取物的量不低于低分子量聚合物组分的15重量%。

    • An LED light source device capable of making the amount of light of an emitting region a predetermined amount of light or more and uniformizing the amount of light is provided. The LED light source device 1 includes an ultraviolet LED array 3 including an LED juxtaposition region R in which LEDs 10 that emit ultraviolet light toward the front are juxtaposed, and a light transmitting member 4 provided on the front side of the LED juxtaposition region R of the ultraviolet LED array 3 so as to be opposed thereto, showing a rectangular parallelepiped outer shape, and formed of a material containing quartz. At a front surface 10a of the LED 10, an emitting surface S surrounded by a marginal portion 11 of a predetermined width H and for emitting the ultraviolet light is provided. Here, when viewed from the front, an end of the light transmitting member 4 is located between inside by ½ of the predetermined width H and outside by ½ of the predetermined width H with respect to an end of the LED juxtaposition region R of the ultraviolet LED array 3.
