Abstract:
The thermal fuse of the present invention contains a fuse element (1) that is formed of a fusible alloy having a composition of 43.5 - 50 wt% Sn, 0.1 - 5 wt% In, and balance being Bi and inevitable impurities, or a fusible alloy having a composition of 5 - 33 wt% In, 4.7 - 15.5 wt% Zn, and balance being Sn and inevitable impurities; a pair of electric terminals (2) and (3) connected to the fuse element; and case (8) for accommodating at least the fuse element (1). The opening end of case (8) has a predetermined shape. By employing the structure above, a thermal fuse having an operating temperature as high as 130 - 190 C can be easily obtained.

Abstract:
An resin composition comprising an oligo(meth)acrylate having one or more (meth)acryloyl groups within one molecule, an allyl monomer of a saturated and/or unsaturated polybasic acid, and an acetoacetamide compound. The problem of reduction in curability at an ordinary temperature can be solved in a radical curable resin composition comprising an oligo(meth)acrylate diluted with an allyl monomer.
