  • Patent number: 6828943
    Abstract: 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.

  • Patent number: 5624544
    Abstract: An ionized water stably maintaining a strong pH value for a long period is manufactured. Plural electrolytic cells disposing cylindrical cathodes and anodes across a cylindrical electrolytic diaphragm with a bottom made of clay ceramics are disposed in an electrolytic bath. Alkaline ionized water produced in the electrolytic diaphragm is supplied into the electrolytic diaphragm of the adjacent electrolytic cell, and electrolyzed in the electrolytic cell. In the electrolytic diaphragm of each electrolytic cell, crystalline clay minerals are dissolved, and alkaline ionized water of high intensity is sequentially produced, and at the outside of the electrolytic diaphragm of each electrolytic cell, crystalline clay minerals are dissolved, and acidic ionized water of high intensity is sequentially produced.
