Patent number: 11786922Abstract: A voltage application device includes a voltage application circuit. The voltage application circuit applies application voltage between discharge electrode and counter electrode which face each other with a clearance left from each other to generate a discharge. The voltage application device forms discharge path partially and dielectrically broken between discharge electrode and counter electrode when a discharge is generated. Discharge path includes first dielectric breakdown region formed around discharge electrode, and second dielectric breakdown region formed around counter electrode.Type: GrantFiled: July 25, 2019Date of Patent: October 17, 2023Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Tetsunori Aono, Jumpei Oe, Yohei Ishigami, Kana Shimizu, Takafumi Omori, Yukari Nakano, Takayuki Nakada

Patent number: 11623230Abstract: Voltage application device includes voltage application circuit. Voltage application circuit applies a voltage to load including discharge electrode that holds liquid, voltage application circuit generating discharge in discharge electrode. During a drive period, voltage application circuit periodically changes a magnitude of the voltage applied to load at a drive frequency within a predetermined range including a resonance frequency of liquid, voltage application circuit mechanically vibrating liquid.Type: GrantFiled: July 24, 2018Date of Patent: April 11, 2023Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yohei Ishigami, Jumpei Oe, Yukari Nakano, Takafumi Omori, Tetsunori Aono, Kana Shimizu

Patent number: 11552457Abstract: A discharge device according to the present disclosure includes a discharge electrode and a voltage applicator that applies a voltage to the discharge electrode and thus causes discharge that is further developed from corona discharge at the discharge electrode. The discharge is discharge in which a discharge path is intermittently formed by dielectric breakdown so as to stretch from the discharge electrode to a surrounding. This discharge can be called leader discharge. This makes it possible to increase an amount of generated active component while keeping an increase of ozone small.Type: GrantFiled: July 21, 2017Date of Patent: January 10, 2023Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Youhei Ishigami, Masaharu Machi, Takafumi Omori, Tomohiro Yamaguchi, Osamu Imahori, Tetsunori Aono, Takayuki Nakada, Yukari Nakano

Publication number: 20220344912Abstract: An electric discharge device according to the present disclosure includes a discharge electrode, a counter electrode, a voltage application circuit, and a liquid supply unit. The discharge electrode is a columnar electrode. The counter electrode faces the discharge electrode. The voltage application circuit applies an application voltage between the discharge electrode and the counter electrode. The liquid supply unit supplies liquid to the discharge electrode. The liquid extends and contracts along a central axis of the discharge electrode by discharge. The counter electrode includes a peripheral electrode part and a projecting electrode part. In a direction along the central axis of the discharge electrode, a tip of the liquid in a state in which the liquid extends is located at the same position as an outer peripheral edge of the peripheral electrode part or located closer to the discharge electrode than the outer peripheral edge.Type: ApplicationFiled: July 16, 2020Publication date: October 27, 2022Inventors: Yohei ISHIGAMI, Takafumi OMORI, Tetsunori AONO, Sadahiko WAKABA, Takayuki NAKADA

Patent number: 10099232Abstract: An electrostatic atomizing device of the present disclosure includes a discharge electrode, a counter electrode, a liquid supplying unit, a current path, a voltage applicator, and a limiting resistor. The limiting resistor is disposed on a first current path or a second current path included in the current path. The first current path electrically connects the voltage applicator and the counter electrode, and the second current path electrically connects the voltage applicator and the discharge electrode. This makes it possible to increase an amount of generated radicals while keeping an increase of ozone small. In addition, an electric current peak of an instantaneous electric current can be kept small.Type: GrantFiled: July 21, 2017Date of Patent: October 16, 2018Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Tetsunori Aono, Tomohiro Yamaguchi, Takafumi Omori, Osamu Imahori, Takayuki Nakada, Youhei Ishigami
