Abstract: PROBLEM TO BE SOLVED: To obtain the subject copolymer that has further higher transition point and can manifest the functions of recognition of amino acids and optical resolution by copolymerizing a monomer bearing an amino acid residue on its side chain and an N-isopropylacrylamide. SOLUTION: This copolymer is represented by formula I ((m), (n) are each the proportion in weight% of individual components in the copolymer) and is obtained by copolymerizing a compound of formula II (Z is a protecting group for H atom in an amino group; Y is a protecting group for hydroxyl in a carboxyl group, for example, benzyl and the like; protecting group Z is benzyloxycarbonyl, t-butoxy-carbonyl) with N-isopropylacrylamide followed by deprotection of the protecting groups Z and Y. This copolymer is dissolved in water at a lower temperature than the transition point, but causes a phase separation above the transition point and the aqueous solution becomes cloudy, thus it can be expectedly used as a thermally responding polymer. In addition, the copolymer can also be used as a reagent for discrimination of kinds of amino acids and for resolution of amino acids.

Abstract: PURPOSE:To obtain water, required for a closed space, as circulating water instead of the feed of water from the outside by using a high moisture absorption heat-sensitive high molecular gel prepared in a way that the surface of a heat-sensitive high molecular gel is impregnated with a material to promote absorption of steam and/or the material is kneaded and fixed at the inside. CONSTITUTION:A high moisture absorption heat-sensitive high molecular gel (reinforced gel) 3 prepared such that the surface of a heat-sensitive high molecular gel is impregnated with a material to promote absorption of steam and/or the material is kneaded and fixed at the inside is installed in a closed space 1. When, during the night, an outside air temperature is reduced to a value lower than the phase transition temperature of the reinforced gel 3, steam 4 is hydrated and contained in the reinforced gel 3. When, during a daytime, the outside air temperature is increased and the temperature of a gas phase part in the closed space 1 is increased to a value higher than the phase transition temperature of the reinforced gel 3, a moisture content held by the reinforced gel 3 produces water 5 being liquid, phase separation from the reinforced gel 3 is effected, and the water is fed to soil 7 and a steam divergent substance 6. This method and constitution facilitate formation of a water circulation system in the closed space.

Abstract: PURPOSE:To obtain a reaction carrier for the production of immobilized enzyme or microorganism having excellent activity and high reaction rate, by using of a fluid- permeable hollow fiber capable of selectively permeating gas and liquid and coating the outer surface of the hollow fiber with fiber for the immobilization of enzyme or microorganism. CONSTITUTION:A porous ceramic hollow fiber or a hollow fiber having oxygen- enriching function such as polysiloxane fiber is used as a fluid-permeable hollow fiber and the outer surface of the hollow fiber is covered with fibers for the immobilization of enzyme or microorganism, preferably ultrafine fiber of aminoacetalized polyvinyl alcohol having a diameter of preferably 0.05-1mum e.g. by knitting or weaving the immobilization fiber round the hollow fiber in the form of knit strings or winding the immobilization fiber around the hollow fiber. As an alternative method, the hollow fiber and the immobilization fiber are blended and woven to a fabric. When the reaction substrate is a single-component substance, the substrate is introduced into the hollow part of the hollow fiber and when the substrate is two-component substance, a component is introduced into the hollow part and the other component is directly supplied to the fibrous immobilized enzyme or microorganism to enable the efficient conversion of the substrate to a reaction product.

Abstract: PURPOSE:To provide an automatic hot and cold water selector valve having a simple structure and requiring no drive power by applying the constitution where a valve member is formed with heat reversible expansion and contraction material for employing the expanding and contracting behavior of a valve itself, and hot water or cold water is thereby selected automatically. CONSTITUTION:The inside of a hollow box type main body 1 is divided into a feed water chamber 2 at a lower level and a hot water chamber 3 and a cold water chamber 4 at an upper level. The chambers 2 to 4 are respectively fitted with pipe lines 2a to 4a for communication with the outside. By introducing cold water from the pipe line 2a to the feed water chamber 2, each of valve members 3d and 4d is caused to expand, and a through-hole 3b is thereby closed, while another through-hole 4b is opened, thereby introducing cold water from the chamber 2 only to the cold water chamber 4 and discharging the water outside through the pile line 4a. On the other hand, each of the members 3d and 4d is caused to contract by introducing hot water to the feed water chamber 2 and the hole 3b is thereby opened, while the hole 4d is closed, thereby introducing hot water from the chamber 2 only to the hot water chamber 3 and discharging the water outside through the pipe line 3a.

Abstract: PURPOSE:To reduce the load of a water supply system and to decrease laminar film resistance by discharging exhaust gas in the vicinity of an interface between a gas separation membrane and water, and utilizing the movement of the bubbles generated at this time. CONSTITUTION:A hollow yarn-based gas separation membrane 3 is fixed in the housing 1 of the device for recovering oxygen dissolved in water by means of the upper and lower fixing layer 2 consisting of an adhesive. The exhaust gas used in combustion, respiration, etc., is discharged through a diffusion plate 5, and sent up as bubbles 10 in a passage 8 between membranes while accompanying and circulating the water from an outlet 4. The laminar film resistance on the surface of the gas separation membrane 3 is simultaneously removed, and the exhaust gas is discharged from an outlet 9 along with the water 12. Meantime, the oxygen and other gases dissolved in water is passed through the gas separation membrane 3, recovered, and discharged from a line 7. By this method, the device can be miniaturized, and energy can be saved.
