摘要:
A surface treating apparatus has a first sheet containing unit; a second sheet containing unit; and a sheet driving unit to pull out an elongated sheet from the first sheet containing unit and move it to the second sheet containing unit as the apparatus moves on a surface to be treated. A sheet contacting member contacts one side of the sheet moving from the first sheet containing unit to the second sheet containing unit and brings the other side of the sheet into contact with the surface to be treated when the apparatus moves thereon. The elongated sheet is moved to wipe or apply wax or the like on the surface to be treated as the apparatus moves on the surface while renewing the portion of the sheet to be brought into contact with the surface when desired.
摘要:
To provide a generator capable of generating plasma and ozone with high efficiency and easy to handle, with a simple structure. An electrode part 10 is formed of electrodes 11 and 12 without dielectric material interposed therebetween. An arc-extinguishing capacitor 13 as a charge storage part for storing charge is connected in series to the electrode part 10. An AC power source 15 generating plasma by causing self-arc-extinguishing discharge between the electrodes 11 and 12 by applying AC voltage to charge and discharge the arc-extinguishing capacitor 13, is connected to both ends of a circuit in which the electrode part 10 and the arc-extinguishing capacitor 13 are connected in series. The arc-extinguishing capacitor 13 and one electrode 12 of the electrode part 10 connected thereto are unitized, for making the electrode part multi-polarized. A unit is constituted of a floating electrode serving as both of the one electrode 12 of the electrode part 10 and one electrode of the arc-extinguishing capacitor 13, an insulating material provided around the floating electrode and a grounding electrode provided around the insulating material.
