Abstract
Supplying a predetermined amount of electric energy to a fine metal wire 4 in a short time causes the fine metal wire 4 to melt and evaporate. Following this phenomenon, a blasting substance 10 expands in volume, so that the evaporative expansion force resulting from the melting evaporation of the fine metal wire 4 is transmitted to and blasts a to-be-blasted object 5.
Claims1
A blasting apparatus for blasting a to-be-blasted object by supplying electric energy to a fine metal wire for a short time to rapidly melt and evaporate the fine metal wire, comprising:
- a retaining member having a recess formed in a surface of the retaining member for retaining the fine metal wire, and a blasting substance filled in said recess as a pressure transmitting substance;
- and
- the recess being placed to oppose the surface of a blasting part of a to-be-blasted object at the time of blasting the to-be-blasted object.
Dependencies are inferred from the claim text.
