Abstract: PROBLEM TO BE SOLVED: To make it possible to economize an amout of supply water without damaging the effect of purification by making secondary purification of water pumped from a pool after primary purification to return the water to the pool, and returning reverse washing water after the reverse washing in a reverse washing process of secondary purification treatment to a supply side of primary purification treatment. SOLUTION: Water pumped from a pool 1 through a water supply pump 4 is supplied to a solid-liquid separator 6 through a water level adjusting tank 5 and is transferred to a filteration water tank 7, and secondary purification is made with a fine filter 3. Water purified by the secondary purification is partially flowed out from the filteration water tank 7 to a piping 11 through a branch pipe 9 to return to the pool 1, the remaining water is supplied to the fine filter 3 with a water supply pump 8 and is finely filtered, and it is returned to the pool 1 through pipings 10 and 11. Facilities for a reverse washing process are provided to a coarse filter 2 and the fine filter 3, the reverse washing water after the reverse washing is supplied to the water level adjusting tank 5 on the supply side of the coarse filter 2 for making primary purification treatment through a drain pipe 17, and pool water pumped from the pool 1 is mixed with the reverse washing water and is filtered again with the coarse filter 2.

Abstract: PROBLEM TO BE SOLVED: To prevent raised naps from being entwined with each other to greatly reduce difficulties in cleaning by providing a suction means and a means to move the suction means and a surface on raising side, along the surface on raising side in a normal direction or reverse direction with respect to raising direction. SOLUTION: When a suction means is oriented in a raising direction or in a reverse direction, i.g., a-a' direction, suction can be effected without disarranging raised naps 51. When the means is moved perpendicular to raising direction, i.g., b-b' direction, most of the raised naps 51 are pulled in the direction b-b' so that a raised layer is disarranged in such a manner that a base fabric is exposed or naps brought down 51 in the direction b-b' and naps, which are being raised to their original positions, are entwined with each other. As a result, solid particles get into weave textures or networks of base fabrics or into between entwined naps 51, and hence it becomes difficult for the suction means to conduct cleaning. Thus, relative movement of the means is directed in a normal or reverse direction, i.g., a-a' direction, to prevent the naps from being disarranged so that the raised cloth can be efficiently cleaned.

Abstract: PURPOSE: To conduct proper purification according to the properties of raw water, to obtain highly transparent water, and to improve the general versatility of a filter for water. CONSTITUTION: An apparatus is composed of a main body 2, the first filtration means 6 which filters raw water, and the second filtration means 7 which filters the filtrate from the first filtration means 6. The first filtration means 6 and the second filtration means 7 use a precision filtration means and an adsorption filtration means according to the degree of filtration, i.e., the required transparency of the purified water.

Abstract: PROBLEM TO BE SOLVED: To provide a front plate for a screen display device which is excellent in the durability of an antireflection film layer mainly for a portable electronic apparatus terminal and makes a vapor deposition film (antireflection film) hardly peelable like scales and makes the screen display device easily visible even if the front plate is scratched by skin or cloth in the state that the secretions, such as sweat, emitted from the human body stick thereto. SOLUTION: The front plate for a screen display device which has excellent wear resistance for sweat and has a total ray transmittance of >=50% and a visual reflectivity of
