  • Publication number: 20220323967
    Abstract: An electric pulse decomposition method for separating a composite material by an electric pulse, the composite material being obtained by bonding or joining a plurality of conductors to each other with an insulating member, the electric pulse decomposition method including a protrusion formation step for forming a protrusion in a specific site, on a side on which the composite material is arranged, of at least one of the plurality of conductors, and a separation step for separating the plurality of conductors in the composite material 1 by respectively bringing electrodes into contact with surfaces of the plurality of conductors and applying an electric pulse between the electrodes to destroy the insulating member. This makes it possible to separate the plurality of conductors from the composite material by making a shock wave caused by a current of the dielectric breakdown functioning as an adhesive to effectively destroy the insulating member.

  • Patent number: 10792671
    Abstract: A disassembling apparatus that shatters an object by means of pulsed discharge includes a container that can be filled with a liquid, an anode that is disposed within the container, a cathode that is disposed such that the object can be placed so as to straddle the anode and the cathode, object scattering prevention means that encloses an object disassembling region above the anode and the cathode, and a pulsed power supply that applies a high voltage pulse between the anode and the cathode.

  • Patent number: 10160668
    Abstract: The present invention seeks to decompose and remove various types of organic materials contained in oilfield water by one operation. To this end, this method for treating oilfield water is provided with: a step for obtaining primary treated water containing organic material by removing the solid content and oil content from oilfield water; and a step for decomposing the organic material by exposing the primary treated water to discharge plasma, wherein the discharge plasma is generated by a nanosecond pulse power source for outputting a pulse having a pulse width of 10 ns or less.

  • Patent number: 7838791
    Abstract: A metal coating removing apparatus (1) includes a first electrode (13) arranged so as to be opposed to a metal coating (101) as an object to be removed, a second electrode 14 arranged so as to be opposed to the metal coating (101) at a predetermined distance from the first electrode (13), and a pulse power generator (11), for example, that functions as a discharge energy supply portion. The pulse power generator (11) supplies discharge energy between the first electrode (13) and the second electrode (14) so as to allow discharging to occur between the first electrode (13) and the second electrode (14). By allowing discharging to occur between the first electrode (13) and the second electrode (14), the metal coating (101) can be removed.
