    • The pressure-sensitive resistor comprising an electroconductive elastomer, in which an electroconductive particulate material is dispersed, two electrodes placed on the opposing surfaces of the elastomer, a means for providing a compressive force between the electrodes and a means for adjusting the compressive force, works on a novel principle that the elastomer composite exhibits a positive coefficient in the curve of compression vs. resistance relationship when the compressive force is varied in a region exceeding an inversion point at which the resistance of the elastomer as measured in the direction of compression is minimal. The coefficient in this positive region is smaller than in the ordinary negative region, so that the variable resistance of the resistor can be controlled very delicately together with the decreased contribution of the uncontrollable contact resistance.
    • 压敏电阻器包括导电弹性体,其中分散有导电颗粒材料,放置在弹性体的相对表面上的两个电极,用于在电极之间提供压缩力的装置和用于调节压缩力的装置的工作 基于弹性体复合材料在压缩力与电阻关系曲线中呈现正系数的新颖原理,当压缩力在超过在压缩方向测量的弹性体电阻最小时的反转点的区域中变化时 。 该正区域中的系数比普通负区域小,因此可以非常精细地控制电阻器的可变电阻以及不可控接触电阻的减小的贡献。

    • The present inventors provides polyol-containing resin compositions for coatings which can give cured coating films having high hardness and at the same time high solid compositions to meet the recent resources saving and/or environmental protection requirements, and curable coating compositions having high reactivity at curing, giving the coating film with good appearance and the coatings with prolonged pot life. The invention is directed to a resin composition for coatings comprising a polyol (A1) or (A2), a polyether polyol (B) and a solvent (C), wherein the polyol (A1) comprises a hydroxyl-containing polymerizable unsaturated monomer and a ring structure-containing polymerizable unsaturated monomer as essential components and the polyol (A2) comprises a hydroxyl-containing polymerizable unsaturated monomer and a linear branched structure-containing polymerizable unsaturated monomer as essential components.
