  • Method of producing electrolyzed water
    Patent number: 6716335
    Abstract: The method of this invention for producing electrolyzed water containing ozone employs an apparatus for producing electrolyzed water from a liquid. The apparatus has two plate electrodes facing each other, a D.C. power source for applying a D.C. voltage across the electrodes and a control circuit for changing a polarity of the electrodes alternately. The method includes the step of producing electrolyzed water by changing the polarity, while a liquid is caused to flow in a flow passage between the electrodes, and the polarity is changed at an interval of time T as defined by formula (10): 0.5≦T≦(1/3)×(L/V)  (10) wherein; V: Velocity of flow of the liquid in the flow passage (cm/sec.), and L: Length of the electrodes as measured in the direction of flow of the liquid (cm).

  • Sterilizer
    Patent number: 5820821
    Abstract: A sterilizer supplies liquid over an object and then irradiates far-infrared radiation to the object. The object is fully sterilized since the supplied liquid well absorb far-infrared radiation with sterilizing effect.
