The initiation of small amount of the explosive was performed by the wire explosion that is generated by the instant release of electric energy from capacitors, and the expected impulsive forces were obtained under the controlled condition. In order to avoid the damages in applications caused by wave interactions and gas emissions, the concentration of rising forces and the isolation from superfluous energy in devices were considered. Local attachment of metals and wearing fine through-hole were tried in the first instance of applications, and the conditions and the estimation procedures lead to successful results.
