  • Publication number: 20210233748
    Abstract: In the present invention, a gas passing groove, a high-voltage electrode groove and a ground electrode groove formed in an electrode unit base are each spiral in plan view. A high-voltage electrode is embedded in the high-voltage electrode grove, and a ground electrode is embedded in the ground electrode groove. The high-voltage electrode and the ground electrode are arranged on sides of opposite side surfaces of the gas passing groove in the electrode unit base to oppose each other with a portion of the electrode unit base and the gas passing groove therebetween, and are spiral in plan view along with the gas passing groove.

  • Patent number: 10971338
    Abstract: In an active gas generating apparatus, a power feeder is provided above metal electrodes in an integrated high-voltage electrode unit. When seen in plan view, the power feeder has a shape that entirely covers the metal electrodes in the integrated high-voltage electrode unit. Each of power feeding units is provided below the metal electrodes in an integrated ground electrode unit. When seen in plan view, each of the power feeding units has a shape that entirely covers the metal electrodes of the integrated ground electrode unit.

  • Publication number: 20210057192
    Abstract: In the present invention, a high-voltage side electrode component further includes a conductive film disposed on an upper surface of a dielectric electrode independently of a metal electrode. The conductive film is disposed between at least one gas ejection port and the metal electrode in plan view, and the conductive film is set to ground potential.

  • Publication number: 20200343078
    Abstract: The present invention has features (1) to (3). The feature (1) is that “an active gas generation electrode group is formed in such a manner that a ground side electrode component supports a high-voltage side electrode component”. The feature (2) is that “stepped parts are provided in a discharge space outside region of a dielectric electrode in the high-voltage side electrode component, and project downward, and by a formation height of these stepped parts, the gap length of a discharge space is defined”. The feature (3) is that “the high-voltage side electrode component and the ground side electrode component are formed to have the thickness of a discharge space formation region relatively thin and the thickness of a discharge space outside region relatively thick”.

  • Publication number: 20200260565
    Abstract: A gas passing groove, a high-voltage electrode groove, and a ground electrode groove provided to an electrode unit base are each helical in plan view. An electrode unit lid is placed on a front surface of the electrode unit base so that a high-voltage conduction hole and a high-voltage conduction point coincide with each other in plan view. An electrode cooling plate is placed on a front surface of the electrode unit lid so that a high-voltage opening includes the high-voltage conduction hole as a whole in plan view. The electrode unit lid and the electrode cooling plate are placed on the front surface of the electrode unit base so that a ground conduction groove, a ground conduction hole, and a ground conduction point coincide with one another in plan view.
