Abstract: There is provided a protective tube structure for a thermometer in which a gap between an anti-vibration strip and a surface of a protective tube is eliminated to prevent corrosion of the protective tube, and the anti-vibration strip can be easily formed. The protective tube structure for a thermometer includes: a cylindrical portion 2; and one or more projected rims 3 formed into a spiral on an outer wall of a barrel of the cylindrical portion 2, and the projected rim 3 is formed by cutting an outer surface of a barrel of a cylindrical member.

Abstract: A water pot with an electrolyzing device comprises a pot body having an opening at the top thereof and a handle, the pot body including an electrolyzing vessel divided into two chambers by a porous partition formed into a hollow shape, the chambers having therein negative and positive electrodes respectively, means for removing the water from the positive electrode chamber after an electrolyzing operation, a cover detachably mountable on said opening at the top of the pot body, said opening being adapted to supply water to the vessel and said hollow porous partition being adapted to be inserted into the vessel and removed therefrom through said opening. A nozzle is formed in the cover or in the remaining portion of the pot body so as to communicate with the negative electrode chamber.

Abstract: A device for regulating drinking water includes an electrolyzer divided into a negative electrode chamber and a positive electrode chamber by an unglazed partition, and electrodes disposed in the chambers and adapted to be energized by direct current for a prescribed period time for separating water in the electrolyzer into two components having hydroxyl radical in different densities, due to the electrolysis and electroendosmose. The negative electrode has a heating element disposed in a hollow space formed in the negative electrode to warm up the water body in the electrolyzer at each time of the electrolysis.
