    Abstract: A power source device includes a capacitive load; and an AC power source, as a voltage source, which applies AC voltage to the capacitive load. A series circuit composed of an inductor and a capacitor is connected to the AC power source. A series circuit composed of a load inductor and the capacitive load is connected in parallel to one of the inductor or the capacitor. If an inductance of the inductor is defined as Lp, a capacitance of the capacitor is defined as Cp, an inductance of the load inductor is defined as Ls, an equivalent capacitance of the capacitive load is defined as Cs, and a frequency of the AC power source is defined as fv, the following expressions are satisfied,

    Abstract: This invention is provided with: a wind tunnel that, while keeping an insulating distance to pair-forming coils, surrounds a region from a yoke portion of a core to at least a part of the pair-forming coils, to thereby guide a flow of cooling air for the pair-forming coils into an extending direction of leg portions; a supporting structural member that is fixed to the yoke portion to support inside the wind tunnel, the core and the pair-forming coils; and a windshield plate that partly shields a gap between the pair-forming coils and the wind tunnel; wherein, in the supporting structural member, air holes for passing the cooling air therethrough are formed in corresponding to inner gaps of the coils.

    Abstract: This invention aims at improving the reliability of the electrode in an ozone generator, and also at shortening the start-up time of the ozone generator after the maintenance. The ozone generator comprising; a dielectric discharge tube, having a closed end and an open end which are faced each other, and including an electrode formed on an inner surface thereof, a sealing lid, covering the open end of the dielectric discharge tube and fixed to the dielectric discharge tube with an adhesive, a power supply brush, in inscribed contact with the electrode formed on the inner surface of the dielectric discharge tube, and a grounding electrode, arranged concentrically with the dielectric discharge tube; wherein the sealing lid includes a main body part and a cylinder part, which are connected together, and an inside diameter of the cylinder part is larger than an outside diameter of the dielectric discharge tube.
