  • Patent number: 11505463
    Abstract: A small-scale application apparatus including an ozone generation apparatus configured to generate ozone gas, the application apparatus being configured to perform ozone usage processing. The ozone generation apparatus includes a load-resonant high-frequency step-up transformer configured to obtain a stepped-up high-frequency voltage and an ozone generator configured to receive the stepped-up high-frequency voltage as an operating voltage to generate the ozone gas having an ozone concentration of at least 200 g/m3 from raw gas containing oxygen gas. The application apparatus receives the ozone gas under a pressure environment of at least 0.2 MPa.

  • Patent number: 10745277
    Abstract: As a metal compound layer provided between a dielectric and a ground electrode of an ozone generator, there is used a metal compound satisfying the condition (1) the metal compound is not a substance promoting ozone decomposition, the condition (2) the metal compound is not a conductor, the condition (3) the band gap of the metal compound layer is in the range of 2.0 to 4.0 (eV), and the condition (4) the hole potential of a valence band portion formed in the excited state of the metal compound layer is larger than the binding potential (1.25 (eV)) of an oxygen molecule. In addition, as ozone generation processing are executed under an environment in which various ozone decomposition suppression requirements for suppressing a decomposition amount of ozone are imposed on the ozone generator.
