    • A pressure sensor has a case having a first side and a second side, and a sensing portion mounted to the case. A first diaphragm is disposed on the first side of the case such that a first chamber is defined. A second diaphragm is disposed on the second side of the case such that a second chamber is defined. The first chamber and the second chamber are filled with a pressure medium such as an oil. The case forms an introduction passage for introducing the pressure medium into the first chamber and the second chamber. In a condition that the first chamber and the second chamber are filled with the pressure medium, the introduction passage is sealed by a sealing part so that the first chamber and the second chamber are separated from each other and from an outside of the case.
    • 压力传感器具有具有第一侧和第二侧的壳体,以及安装到壳体的感测部分。 第一隔膜设置在壳体的第一侧上,使得限定第一室。 第二隔膜设置在壳体的第二侧上,从而限定第二腔室。 第一室和第二室用诸如油的压力介质填充。 壳体形成用于将压力介质引入第一室和第二室的引入通道。 在第一室和第二室被压力介质填充的状态下,引入通道被密封部分密封,使得第一室和第二室彼此分离并且从壳体的外部分离。

    • A polymer electrolyte composition obtained by mixing a plurality of ion-conductive polymers, wherein if the ion-conductive polymer that is highest in ion exchange capacity among the plurality of ion-conductive polymers is termed first ion-conductive polymer, and the ion-conductive polymer that is lowest in ion exchange capacity is termed second ion-conductive polymer, then the first ion-conductive polymer and the second ion-conductive polymer are both block copolymers composed of a segment having an ion-exchange group and a segment having substantially no ion-exchange groups, and if the weight fraction of the segment having an ion-exchange group in the first ion-conductive polymer is termed Wh1, and the weight fraction of the segment having an ion-exchange group in the second ion-conductive polymer is termed Wh2, then the relations (I) and (II) listed below are satisfied: (I) Wh1>Wh2; (II) Wh1−Wh2≦0.25.
    • 通过混合多种离子传导性聚合物而获得的高分子电解质组合物,其中如果将多个离子传导性高分子中离子交换容量最高的离子导电性聚合物称为第1离子传导性高分子,则离子传导性聚合物 离子交换容量最低的聚合物被称为第二离子导电聚合物,则第一离子导电聚合物和第二离子导电聚合物都是由具有离子交换基团的链段和基本上没有离子交换基团的链段组成的嵌段共聚物 离子交换基团,并且如果在第一离子导电聚合物中具有离子交换基团的链段的重量分数称为Wh1,并且在第二离子导电聚合物中具有离子交换基团的链段的重量分数 称为Wh2,则满足以下列出的关系(I)和(II):(I)Wh1> Wh2; (II)Wh1-Wh2≦̸ 0.25。
