Abstract: An ozone-water feeding facility is able to feed ozone-water at a highly-accurately controlled concentration from an ozone-water producing apparatus to a remote service location even under an intermittent usage condition. The facility includes an ozone-water producing apparatus disposed remote from an ozone-water service location; a circulating pipeline extending outwardly from the ozone-water producing apparatus and returning thereto by way of a neighborhood of the service location; and a short branch pipe branched from the circulating pipeline at the above neighborhood. The ozone-water is intermittently introduced from the branch pipe, to thereby supply the ozone-water at a specific concentration to the service location. The facility may preferably include a discharge side ozone-water conditioning portion for diluting the ozone-water intermittently introduced from the short branch pipe into a specific concentration before the supply of the ozone-water to the service location.

Abstract: An aqueous electrolysis cell for generation of gas includes an electrolysis container having an anode chamber and a cathode chamber separated from each other by a membrane. An anode and a cathode having permeability to gas and water are fitted on respective surfaces of the membrane. A first sealing element is fitted on the anode and the membrane to surround and seal circumference of the anode, one surface of the first sealing element being in tight contact with one surface of the membrane, and the first sealing element has an opening communicating with the anode. An anode current collector plate has one surface in tight contact with the other surface of the first sealing element, and a through-hole communicating with the opening of the first sealing element. A second sealing element has one surface in tight contact with the other surface of the anode current collector plate, and an opening communicating with the through-hole of the anode current collector plate.

Abstract: An automatic faucet device capable of cleaning and sterilizing a human body of a user with no stress given to the user. The device includes: a water supply head; a first solenoid valve interposed in the course of a pipe connecting the water supply head to a pre-cleaning water source; a second solenoid valve interposed in the course of a pipe connecting the water supply head to an ozone-water source; and a sensor for detecting the presence of a substance such as a hand of a human body under a discharge port of the water supply head. The first solenoid valve is opened for a specific period of time A in response to a signal detected by the sensor, and the second solenoid valve is opened for a specific period of time C after an elapse of a specific period of time B since starting of the opening of the first solenoid valve.

Abstract: An aqueous electrolyte ozone generating system includes on electrolyte tank and liquid-vapor separator tank. Electrolyte tank has a liquid supply port located at its upper part which allows ozone gas-containing liquid (generated at an anode) to be supplied to the liquid vapor separator tank. Water at the bottom part of an separator tank flows back to the anode chamber of the electrolyte tank through a return port, and fresh water is replenished to the system simultaneously while the temperature of the water in the separator tank is controlled. Liquid-vapor separator tank is thin in horizontal width and long in the vertical direction. A heat exchanger wall is installed to and covers most of the surface area of at least one side of the separator tank. A temperature control, capable of providing a cooling effect, is integrally installed to the heat exchanger wall.

Abstract: An apparatus for producing ozone water by accelerated mixing and dissolving of ozone into water due to an enhanced contact efficiency of ozone gas and water with controlled temperature includes a circulation line for circulating ozone water and employs a jet nozzle (4) in a conduit (4) which returns the ozone water from the circulation line into a primary container. This causes negative pressure about the outlet of the nozzle, whereby the ozone gas is sucked into the water which is jetted. Thus, the ozone gas is rapidly mixed and dissolved into the water. Efficiency of stirring of the ozone water is also enhanced. A secondary container is provided in the circulation line, which specially facilitates cooling of the ozone water as well as prevention of freezing.

Abstract: Hereby established is a method of disinfection by ozone which is safe, clean, more reliable, and more efficient than prior methods. The method comprises a step of calculating the amount of ozone which would be required to solely disinfect bacteria if there were no co-existing materials, a step of calculating the amount of ozone which will be consumed by actual co-existing materials and a step of applying the total value of the two ozone amounts in proper forms, such as, gas or liquid, etc., preferably in the form of aqueous solution, to the object to be disinfected. This method can be consistently adopted for disinfection on very wide varieties of bacteria.
