Abstract: A distribution tube includes multiple liquid discharge openings provided in a sidewall of a tube body that has one liquid inlet, but is sealed off at its front end. The liquid distributor has a simple structure that allows manual adjustment of the amount of liquid discharged from the liquid discharge openings. In another embodiment, the tubular liquid distributor has a tube body with openings for liquid inlets at both ends and the center part is sealed. The sidewall of the tube body has multiple liquid discharge openings. Multiple entrance sealing rods that each have a conical tip are located on a sidewall opposite to the multiple liquid discharge openings and threaded into the tube body.

Abstract: An electrode structure for electrolysis of water comprising a sheet formed from an electrically non-conductive material whose both sides are laminated with a sheet formed from an electrically conductive material, and a plurality of holes having been bored through said laminated sheet. A net shape sheet of an electrically non-conductive material or an electrically conductive material can be used as the electrically non-conductive sheet or as the electrically conductive sheet. After setting one said electrically conductive sheet as an anode and another one as a cathode, the sterilization of water by electrolysis is carried out by immersing at least a portion of the electrode structure into water, and applying an electric voltage across the anode and the cathode.

Abstract: This invention relates an electrode composition for electrolysis of water, which is comprised of a panel of which one surface is made from electric conductive material and another surface is made from non electric conductive material. Plural holes are bored through said panel, and two said panels are arranged so as to hold a diaphragm between the surface of non-electric conductive material of each panel. And electrolysis reaction occurs at outer side of an anode and cathode of said electrode composition.
