Abstract: PURPOSE:To obtain the column for producing ultra-pure water which easily produces the high-purity water extremely approximate to the theoretically pure water at a high velocity of flow and obviates the fresh elution of impurities by integrating a UV lamp, ion exchanger, precision filter membrane and/or ultrafilter membrane in this order. CONSTITUTION:The water to be treated is irradiated with UV rays 4 and the org. impurities contained therein are decomposed by oxidation. The org. acids and carbon dioxide formed by the oxidation decomposition and the other impurities in the water to be treated are then treated by the ion exchanger 6 and are further subjected to the final filtration by the precision filter membrane and/or ultrafilter membrane 9. The ultra-pure water is thus obtd. without using piping systems for transferring the water to the ensuing stages. The need for pipings and joints is eliminated by the above-mentioned integration and, therefore, the extremely compact column for producing the ultra-pure water is provided. In addition, the degradation in the water quality by the pollution with the impurities eluted from the members, etc., are prevented.

Abstract: PROBLEM TO BE SOLVED: To manufacture a fluid ejector and an emergency water generator by metal, fabricate them by resin, and reduce a manufacturing cost by constituting them of a case and an ejector main body, forming an outer periphery of an intermediate part of the ejector main body as a diameter smaller than an outer periphery of both end parts, and boring a fluid sucking pore in a small diameter part. SOLUTION: A case 10 has a vacuum port 8, a fluid supply port 6 and a blowout port 7, and forms a communicating passage. The passage to the blowout port 7 from the fluid supply port 6 is desirable to be a cylindrical shape having no projection or the like since an ejector is incorporated. On the other hand, the vaccum port 8 is almost vertically arranged, and sucks fluid. An ejector main body 11 is formed as a structure having a nozzle part to squeeze the fluid and a diffuser part communicated with the other end, and an outer periphery of an intermediate part of the ejector main body 11 is formed as a diameter smaller than an outer periphery of both end parts. A fluid sucking pore 13 is bored in a small diameter part. The ejector main body 11 is fitted to and installed in the case 10, and secures airtightness. Reduction in a manufacturing cost can be expected in both metallic and resin products.

Abstract: PROBLEM TO BE SOLVED: To obtain an intake apparatus capable of setting a raw water intake port at a predetermined water depth position by providing a strainer, a pipe taking out taken-in water and a float. SOLUTION: As an intake port for taking in water, a strainer 1 made of a plastic net or a metal net pref. having about 10-50 mesh is provided to the leading end of a hose. In order to set this raw water intake port at a predetermined water depth position, a float 3 and a wt. are provided. The float 3 has a cylindrical or doughnut like shape composed of foam or a hollow member and a pipe-shaped intake pipe also used as a pole achieves the function thereof. The float 3 is pierced through this pole 4 to adjust buoyancy balance. An air vent is provided to the pipe hole of the pole 4 and, further, an air vent valve 9 using a non-return cone is provided to the air vent. When raw water is sucked from the near sea or rivers in case of emergency at a time of disaster, it is prevented that waste refuse on the surface of water or the precipitate on the bottom of water is sucked.
