摘要： PURPOSE:To make contamination of a filtrate side extremely little and to enable exchanging of a membrane element by integrally bonding and fixing both a hollow yarn membrane part and a cap body forming a flow path of filtrate into one body. CONSTITUTION:Hollow yarn membranes 7 are bundled nearly straightly and both ends are fixed, and the end faces of the membranes 7 in a fixing part 4 side are opened and the end faces of the membranes 7 in a fixing part 5 side sealed. A cap body 3 having a filtrate outlet 9 and a flange 10 is liquid- tightly bonded to the fixing part 4 and both fixing parts 4, 5 are fixed to both end parts of a perforated rigid cylindrical body 6 and thereby a membrane element 1 is formed. A hollow yarn membrane module is manufactured by fitting the membrane element to a housing 2 having a flange 11 supporting the cap body 3, a water supply inlet 8 and a water supply outlet 13 and fixing the flanges 10, 11 via a sealing member 12 and integrating them into one body. By such a way, contamination of the contact face of filtrate at a time for manufacturing the module can be prevented and the membrane module can be easily exchanged.

摘要： PURPOSE:To prevent cutting troubles of hollow yarns and extend their service life by fixing protective yarns having similar properties to the hollow yarns with a cured layer around the outsides of upper and lower end parts of a plurality of hollow yarns and surrounding each end part of the hollow yarns with the protective yarns. CONSTITUTION:Each upper and lower end parts of a plurality of hollow yarns 1 are fixed with adhesive cured layers 3, 5 and the hollow yarns are gathered while each yarn being kept in a distance. A protective yarn 7 having similar properties to the hollow yarns is fixed with the cured layer around at least the outside of the upper part of each upper and lower end parts of a plurality of the hollow yarns 1 so as to surround at least the upper part of each upper and lower part of the hollow yarns 1 with the protective yarn 7. As a result, cutting troubles of the hollow yarns are prevented and service life of the hollow yarns are extended.

摘要： PURPOSE:To enhance filtering efficiency by uniformizing the flow of a raw solution to be filtered inside and outside hollow yarn bundles, by adhering and fixing a tubular body having a large number of fine pores provided to the side surface thereof in the central side of hollow yarn bundles along with said hollow yarn bundles. CONSTITUTION:A large number of hollow yarns 1 each sealed at one end thereof and opened at the other end thereof and a tubular body 2 sealed at one end thereof and opened at the other end thereof and having a large number of fine pores 4 provided to the side surface thereof are converged at the end parts thereof to adhere and fix said end parts by a resin 3. In this external pressure filtering type filter apparatus using a hollow yarn filter membrane module, a raw solution to be filtered is injected to the surfaces of the hollow yarn membranes through the fine pores 4 of the tubular body 2 to generate the fluctuation of the hollow yarn membranes and penetrated into the parts where the membranes are mutually contacted and, because the membranes function effectively and fine particles adhered to the surfaces of the membranes are washed off, filtering efficiency is enhanced.

摘要： PURPOSE:To bundle and fix hollow fibers without reducing the mechanical strength of bundled and fixed fibers by wetting the separative menbrane comprising the hollow fibers with a liq. having a b.p. above a specified temp. and an angle of contact below a specified angle being insoluble and inactive to epoxy resin. CONSTITUTION:A bundle of hollow fiber having sealed ends is housed in a plastic sheath and epoxy resin is poured into the sheath. A strip of cotton cloth impregnated with aq. glycerin is wound around an end part of the bundle of the hollow fiber not contacting with the liquid epoxy resin so as to keep the part of the bundle in wet condition. The hollow fibers are bundled and fixed by curing the epoxy resin under this condition.

摘要： PURPOSE: To prepare a hollow yarn like semipermeable membrane having a sharp fractionating property and high in filtering efficiency and fractionation efficiency, by stretching a hollow yarn so as to adjust the inner diameter thereof to 85% or less of that at the time of the emission of the hollow yarn.
CONSTITUTION: A 10W40% solution of a polysulfone resin in an org. solvent having compatibility with water is extruded into a coagulation bath from a ring shaped nozzle. The size of the inner die of the ring shaped nozzle is set to 1.18 times or more of the inner diameter size of a hollow yarn membrane to be obtained. By accelerating the wind-up speed in a coagulation bath, the hollow yarn membrane is stretched so as to adjust the inner diameter to 85% or less of that at the emission time of the hollow yarn membrane. By performing the stretching prior to perfectly gelling the resin, fine pores having an extremely uniform size are formed to the inner surface of the hollow yarn and further fixed in a more finely pulverized state by gelling.

摘要： PURPOSE:To obtain raw SAKE having superior quality of GENSHU (SAKE after brewing, not blended with other ingredients) of its own, distributable at normal temperature, less expensively, by filtering unheated ENSHU with a capillary polysulfone ultrafilter ultrafilter having specific properties. CONSTITUTION:A polysulfone resin having a repeating unit shown by the formula in the main chain of the molecule is dissolved in a solvent such as dimethylformamide, etc., made into a film by wet film forming process, etc., to prepare a capillary ultrafilter having 10-60wt% stopping ratio of dextran having 70,000mol.wt. and >=80wt% stopping ratio of dextran having 500,000mol.wt., 0.5-2m/m inner diameter and 0.1-1m/m thickness. A great number of the film are bundled, sealed with a resin at both end parts to prepare an inner-pressure filtration module, and unheated GENSHU is filtered with the module, to give the desired raw SAKE distributable at normal temperature.
