  • Publication number: 20240138812
    Abstract: An ultrasonic wave generation device including: an ultrasonic wave generation source; an ultrasonic wave condensation part; and a waveguide. The ultrasonic wave condensation part has a first reflection surface opposed to the ultrasonic wave generation source and a second reflection surface opposed to the first reflection surface. The first reflection surface reflects the ultrasonic wave, generated from the ultrasonic wave generation source, toward the second reflection surface. The second reflection surface reflects the ultrasonic wave, which has been reflected by the first reflection surface, toward the waveguide so as to introduce the ultrasonic wave into the waveguide. The waveguide protrudes from the first reflection surface to a side opposite the second reflection surface. A recessed portion is formed from the first reflection surface to the second reflection surface side along an outer circumferential surface of the waveguide.

  • Publication number: 20200121379
    Abstract: A plasma irradiation device has a gas flow channel and an electric field generation section and is provided in a handpiece. The gas flow channel is a flow channel for supplying a gas from the outside of the handpiece to a distal end portion of the acting member. The electric field generation section has a first electrode portion, a second electrode portion, and a dielectric member and is disposed in the gas flow channel. The electric field generation section generates an electric field in a space within the gas flow channel by using a potential difference between the first electrode portion and the second electrode portion, thereby producing low-temperature plasma discharge.

  • Patent number: 10450916
    Abstract: Provided is a plasma reactor capable of reliably generating plasma even in the event of inflow of water. The plasma reactor of the present invention includes a plasma panel stack 20, electrically conductive members 51 and 54, a case, and a mat 71. The plasma panel stack 20 has a structure in which electrode panels 30 are stacked, and generates plasma upon application of voltage between the adjacent electrode panels 30. The electrically conductive members 51 and 54 are electrically connected to discharge electrodes of the electrode panels 30. The case houses the plasma panel stack 20. The mat 71 intervenes between the case and the plasma panel stack 20 and fixes the plasma panel stack 20 to the case. The mat 71 is disposed apart from the electrically conductive members 51 and 54 so that gaps S1 and S2 are formed between the mat 71 and the electrically conductive members 51 and 54, respectively.
