Patent ID: 7196336

Claim:
An apparatus for injecting plasma in the atmosphere, the apparatus comprising: a plurality of dielectric panels 13 a , 13 b , 13 c , and 13 d , which are disposed in parallel at predetermined intervals; a gas supply portion 14 , to which the dielectric panels 13 a , 13 b , 13 c , and 13 d are fixed and which supplies a gas to spaces between the dielectric panels 13 a and 13 b , between the dielectric panels 13 b and 13 c , and between the dielectric panels 13 c and 13 d; power electrodes 15 a , 15 b , and 15 c , which are linearly installed near the gas supply portion 14 and between the dielectric panels 13 a and 13 b , between the dielectric panels 13 b and 13 c , and between the dielectric panels 13 c and 13 d , respectively; ground electrodes 16 a , 16 b , 16 c , and 16 d , which are formed in the ends of the dielectric panels 13 a , 13 b , 13 c , and 13 d , respectively; and a high frequency generator 17 , which applies high frequency power to the power electrodes 15 a , 15 b , and 15 c and the ground electrodes 16 a , 16 b , 16 c , and 16 d.
