Patent number: 6828943Abstract: A conventional method for giving reducing properties uses medication or medium and thus, a range in which the method can be utilized is limited, and there is apprehension that the method adversely affects the environment of ecological system. Further, an apparatus for giving reducing properties is large in scale, and there is an adverse possibility that the apparatus adversely affects other electronic equipment. It is an object of the present invention to solve these problems. A plurality of coaxial cables are arranged as radiators 3 in a form of comb teeth-like shape. Each of the coaxial cable has a predetermined length and a dielectric 3c between an internal conductor 3a and an external conductor 3b. The coaxial cables are connected to an oscillator in series for supplying high frequency alternating current.Type: GrantFiled: March 24, 2003Date of Patent: December 7, 2004Inventor: Katsuhiko Deguchi
