    • Provided is a rubber composition capable of providing a molding having: excellent sealing properties, heat resistance, and acid resistance; a low reaction force and low hardness; a reduced compression set; and especially an improved compression set and unsusceptibility to compression cracking at high temperatures. Also provided are a use of the rubber composition and a main body comprising the rubber composition mounted thereon. The rubber composition contains a specific ethylene/α-olefin/non-conjugated polyene copolymer [A], carbon black [B], and surface-modified silica [C] that is obtained by subjecting precipitated silica to surface modification and has a BET specific surface area of 30 to 80 m2/g, a particle diameter of 1.0 to 4.0 μm as measured by the Coulter counter method, and an M value of 50 or more.
    • 提供能够提供具有优异的密封性,耐热性和耐酸性的成型体的橡胶组合物; 反作用力低,硬度低; 减小的压缩集; 特别是改进的压缩永久变形和在高温下压缩开裂的不可接受性。 还提供了橡胶组合物和包含安装在其上的橡胶组合物的主体的用途。 橡胶组合物含有特定的乙烯/α-烯烃/非共轭多烯共聚物[A],炭黑[B]和表面改性二氧化硅[C],其通过使沉淀二氧化硅进行表面改性并具有BET特异性 表面积为30〜80m 2 / g,通过Coulter计数法测定的粒径为1.0〜4.0μm,M值为50以上。

    • A switching device having a central actuator and two outer actuators disposed separately from the central actuator on two sides, wherein the central actuator is a cylindrical dial (23) supported rotatably and depressibly by a pair of spindle bearings (26) included in a base plate; the base plate (25) supporting the dial (23) is fitted in a frame; the outer actuators are pivotable in a direction approximately perpendicular to a direction in which the three actuators are arrayed and about a pivot approximately perpendicular to a direction in which operating surfaces of the outer acutators are pushed to press a contact (30) disposed on the frame; and each of the outer actuators has a to-be-supported piece (34) extending to a position where the outer actuator deviates from a lateral edge of the dial (23) in the rotating direction as viewed from the front. The outer actuator is pivotally attached at the end of the to-be-supported piece (34) to the frame (22) and has a center axis crossing the pair of spindle bearings of the central actuator.
    • 一种具有中央致动器和两个外侧致动器的开关装置,两个外部致动器在两侧与中央致动器分开布置,其中中央致动器是圆柱形表盘(23),其由包括在基板中的一对主轴轴承(26)可旋转地和可压缩地支撑 ; 支撑表盘(23)的基板(25)装配在框架中; 外部致动器可以在大致垂直于三个致动器排列的方向的方向上枢转,并且围绕大致垂直于外部定位器的操作表面的方向的枢轴旋转,以按压设置在框架上的接触件(30) ; 并且每个外部致动器具有延伸到外部致动器从前方观察时沿旋转方向偏离刻度盘(23)的侧边缘的位置的待支撑件(34)。 外致动器在待支撑件(34)的端部处枢转地附接到框架(22),并且具有与中心致动器的一对主轴轴承交叉的中心轴线。
