Abstract: An ozone generation device includes an inverter, an ozone generator, and a reactor. The inverter turns on and off a switching element by pulse width modulation (PWM) control to convert DC power into AC power. In the ozone generator, voltage of the AC power is applied to a dielectric electrode, and discharge is generated in raw material gas flowing in a discharge gap between the dielectric electrode and a metal electrode, so that ozone is generated by the discharge. The reactor is connected in series to a dielectric electrode, and reduces an inrush current that flows through the dielectric electrode when the switching element is switched from off to on by the PWM control by the inverter.

Abstract: An extraction device according to an embodiment, includes an elastic body, first and second pressing units, and a pulling unit. The elastic body includes a first end facing a first direction, a second end positioned opposite from the first end, and a contact face facing a second direction intersecting with the first direction, and can expand in the second direction. The first and second pressing units press the first and second ends. The pulling unit can pull the second pressing unit in the first direction. The contact face comes into contact with an object to be extracted, when the elastic body compressed by pressing force expands in the second direction. When the pulling unit is pulled in the first direction, while the contact face is in contact with the object to be extracted, the object to be extracted is pulled by friction between the object and the contact face.
