    摘要: 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.

    摘要: In the operation button structure, pressing switch contact portions are satisfactorily pressed by a tilting button operating member even if the button operating member and the switch contact portions are a long distance apart from each other or positions of the switch contact portions vary. When an operator's finger presses a right end of a button operating member, a pressing portion on a right side moves in a direction perpendicular to an upper surface of a substrate, whereby a switch contact portion on the right side is pressed. On the other hand, when the finger is lifted from the button operating member, the pressing portion retracts from the switch contact portion by a connecting portion formed in a shape having elasticity.

    摘要: An electronic equipment comprises a battery storage section that may store two types of rectangular battery which are mutually different in thickness, and a cover that covers the battery storage section, in which the electronic equipment is operative upon receipt of an electric power from the rectangular battery stored in the battery storage section. The battery storage section has a holding member movable between a holding position in which a thin rectangular battery is held and a save position in which it is permitted that a thick rectangular battery is stored in the battery storage section. The cover has a stopper section that stops the holding member at both times when the holding member is at the holding position and when the holding member is at the save position.
