Medical application, for example, manner and device for sonic boom generation of electric liquid pressure type crushed stone technique

摘要

(57) Abstract As for this invention, in regard to the manner and the device in order to generate the sonic boom due to the spark discharge of each inter-electrode where electric current supplies electricity intermittently inside the bed material like the water, at that time, as for the sonic boom, it converges to the target of internal. According to this invention, each electrode (3,4) bed material between (14) inside, electric conduction and semiconductive or polarization possibility each piece (15) interposing, containment there, the media (14), each piece which is included there (15) and also, each electrode (3,4) the canning section which makes, the sonic boom around pass (11) in order to be stored inside, is achieved. According to this invention, interval of each electrode usually exceeding critical value, it is possible even with when it increases to achieve voltage discharge with format of spark discharge.
