摘要： PURPOSE: To detoxicate harmful substances in water and to make waste disposable by running a treating sheet carrying an adsorptive substance and a photoreactive semiconductor in the way the sheet partitions a treatment tank 2 into two sections, pouring water to be treated in one section, discharging the water from the other section, and radiating ultraviolet rays to the treating sheet. CONSTITUTION: Water to be treated which comes in a first partitioned chamber 5 through an inlet 2 for the water to be treated enters into a second partitioned chamber 6 after passing a treatment sheet 4. Harmful substances in the water to be treated are adsorbed by an adsorptive material carried on the treatment sheet 4 and, at the same time, impurities are filtered during the time when the water is passing the treatment sheet 4. The adsorbed harmful substances are decomposed by the decomposing function of a photoreactive semiconductor carried on the treatment sheet 4 and activated by radiation of ultraviolet rays from an ultraviolet light source 12. The treated water is discharged out of a treated water outlet 3. The treatment sheet 4 constantly runs during the treatment and a new treatment sheet 4 is brought into contact with the water to be treated.

摘要： PURPOSE:To provide a plug code connection structure which has high performance in waterproofness and escape prevention, and is used for mending a wiring terminal having an engagement piece. CONSTITUTION:A connection cap 23 made of synthetic rubber 23 has a double structure of an outer cylinder 24 and an inner cylinder 25. The cap 23 is held in a close contact by a cylindrical wall of a terminal 5 through elastic deformation. Its escape preventive and waterproof performances are improved. An inner wall 26 having internal teeth are formed on all of the inner wall of the outer cylinder 24. A common connection structure is adapted to an engagement piece 13 in any positional relationship corresponding to an outlet direction of the terminal for reducing a manufacturing cost.

摘要： PURPOSE:To upgrade the quality of a product by making a bottom wall section and all side wall sections of a form a double wall structure, communicating hollow sections through and providing a feeding inlet for heat fluid on the bottom wall hollow section and feeding outlets at the upper ends of all the wall section hollow sections. CONSTITUTION:When placing of concrete into a concrete form is completed, heat fluid for heating is fed into the form by a feeding hose 1. The heat fluid is dispersed from a bottom wall hollow section 6 to all side wall hollow sections 7 through communicating openings 8, flowed upward and discharged into the atomosphere from a discharge outlet 2 to warm the product surface uniformly and heat the same with the proper temperature for curing. Temperature control is carried out to keep the proper curing temperature in compliance with the cement quantity of concrete, the atmospheric temperature and the like. Local cracks and the like are not generated by the process and the curing time is shortened to manufacture products of good quality efficiently therein.

摘要： PURPOSE:To uniformly apply a photosensitive agent or the like to a screen face by applying tension force to plain gauze and holding a uniform contact state between applying squeegees and the screen face over the whole width. CONSTITUTION:In both applicators 40, 40' constituted by unitedly forming tub- like thin grooves 42 expanded to the lower side over the whole width on the positions immediately after the squeegees 41, 41', the required number of positioning chips 43 engaged with positioning parts 36 on applicator holding frames 30, 31 are arranged on their bottoms and gauze tensing rolls 44 are arranged on the head parts of both the longitudinal sides. At the time of applying a coat solution, the screen face is smoothed by the squeegees 41, 41' from the applied face and its reverse face immediately after applying the solution to uniformly and surely apply the coat solution. The thickness of the coat film can be uniformized by applying pressure force to the gauze to be especially loosened on its center by both the right and left rolls 44 on the applying position to set up the gauze in the tensed state.

摘要： PURPOSE:To impart a porous material with wettability with water and improve the gas permeability of the material, by immersing a porous polyolefin resin in a mixture of sulfuric acid and potassium bichromate, thereby corroding the pore wall of the porous material with acid. CONSTITUTION:A porous polyolefin resin, e.g. foam of polyethylene or polypropylene resin having open or closed cell structure is immersed in a liquid mixture of (A) 10-80%, preferably 40-60% aqueous solution of sulfuric acid and (B) 2-30%, preferably 5-10% potassium bicarbonate based on the component B, at normal temperature -70 deg.C for 5-40hr. The wall of the pore is corroded with acid by the intrusion of the liquid mixture into the pores of said porous material to roughen the wall surface of the pore, expand the pore size and remove thin pore walls. The wettability with water and the gas permeability of the porous material can be improved by this treatment.

摘要： PURPOSE:To recover the silver from the washing water certainly and efficiently by using an ion exchange or a metal adsorbing resin tower packed with diatomaceous earth or the said diatomaceous earth mixed by a quarternary ammonium type macroporous resin according to necessity. CONSTITUTION:In the first tower 1, diatomaceous earth capable of catching a colloidal substance effectively is packed and, according to necessity, a quarternary ammonium type macroporous resin capable of adsorbing and separating an org. compound may be blended and packed. The washing water passed through the first tower 1 is passed through the second tower 2. In this second tower 2, a metal recovering ion exchange or a metal adsorbing resin generally used in the silver recovery is packed. Even after the operation for about 2 monthes, the liquid permeability is good and the washing water after passage does not almost contain silver.
