<P>PROBLEM TO BE SOLVED: To provide a freeze preventing and removing device capable of easily and efficiently removing freeze on the surface of an object. <P>SOLUTION: A surface side electrode 4 in the shape of a concentric circle is formed on the surface of a glass layer forming an insulator 6, and a conductive reflecting layer on the back side of the glass is used as a back side electrode 7. If a pulse current is supplied between both electrodes from a pulse current supply source 11, surface plasma 17 is generated from the surface side electrode 4. Freezing occurred on the surface of the glass 6 is prevented by the surface plasma and induction air flow induced thereby, and can be removed when freezing has already occurred. This freeze preventing and removing device utilizing such surface plasma can be used in a wide range of fields such as the front glass of a vehicle, wings of an airplane, a wind generator, and the like. <P>COPYRIGHT: (C)2008,JPO&INPIT |
