    • The battery holding method and structure enable contact points between a battery and terminals to be maintained invariant in location by improving a performance in holding the battery, and accordingly a stable contact resistance can be obtained. A battery holder forms a battery chamber, and the battery chamber makes a space for housing a battery inserted along a lengthwise direction thereof. The battery holder is equipped, on a side surface thereof, with a nail for pressing the battery in touch with the side surface of the battery. When the battery is inserted into the battery chamber, the nail is deformed elastically, and the resulting restoring force thereof fixes the battery in a definite arrangement in the battery chamber with a slight and eccentric displacement.
    • 电池保持方法和结构使电池和端子之间的接触点通过提高保持电池的性能而保持不变,因此可以获得稳定的接触电阻。 电池座形成电池室,并且电池室形成用于容纳沿其长度方向插入的电池的空间。 电池座的侧面配备有用于与电池的侧面接触地按压电池的指甲。 当电池插入电池室时,指甲弹性地变形,并且所产生的恢复力以一定的排列方式将电池固定在电池室中,并且具有轻微偏心的位移。

    • The present invention provides a non-halogen polyamide-imide resin soluble in an amide solvent at a concentration of 10%, the resulting varnish, when stored at 5° C. for 1 month, exhibiting a solution viscosity change ((solution viscosity after 1 month—initial solution viscosity)/initial solution viscosity), expressed as an absolute value, of not greater than 3.0, and the resin having a moisture absorption (25° C., 90% RH, 24 hours) of not greater than 2.0%; a flexible metal-clad laminates using such a resin; and a flexible printed wiring board prepared from such a flexible metal-clad laminate by circuit formation. The flexible metal-clad laminate of the invention does not curl under any conditions, including humid conditions, and exhibits excellent dimensional stability since the heat resistant resin used as an insulation material has low moisture absorption and low thermal expansion coefficient and there is less internal stress in the flexible metal-clad laminate. Moreover, since the solder heat resistance and the insulation properties are not impaired even after humidification and since the heat resistant resin is soluble in organic solvents with high solution stability, the flexible metal-clad laminate of the invention can be inexpensively produced.
    • 本发明提供可溶于10%浓度的酰胺溶剂的无卤素聚酰胺酰亚胺树脂,所得清漆在5℃下储存1个月后,溶液粘度变化((溶液粘度1 月初始溶液粘度)/初始溶液粘度(绝对值)为3.0以下,吸湿性(25℃,90%RH,24小时)的树脂为2.0%以下 ; 使用这种树脂的柔性金属包覆层压板; 以及通过电路形成由这种柔性覆金属层压板制备的柔性印刷线路板。 本发明的柔性覆金属层压板在包括潮湿条件在内的任何条件下都不会卷曲,并且由于用作绝缘材料的耐热树脂具有低吸湿性和低热膨胀系数,并且内应力较小 在柔性覆金属层压板中。 此外,由于即使在加湿之后焊料耐热性和绝缘性也不受损害,并且由于耐热树脂可溶于高溶液稳定性的有机溶剂中,因此可以廉价地制造本发明的柔性覆金属层压板。
