Abstract: PROBLEM TO BE SOLVED: To miniaturize a hollow fiber membrane cartridge while cleaning performance is maintained by filling active carbon in an opening inside a case. SOLUTION: A hollow fiber film cartridge 1 contains a hollow fiber membrane 3 in a cylindrical case 2. The case 2 is formed on a material of, for example, ABS resin or the like. As to the hollow fiber membrane 3, each of a plurality of linear hollow fiber membranes is bent so as to face to a flowout side W1, arranged in a bundle in the case 2, and only the hollow part thereof is exposed outside by potting 4. As the hollow fiber membrane 3, for example, a porous hollow fiber film is used, and as the material, for example, a fluoroplastic or the like of PFA or the like is used. A filling factor in the case 2 of the hollow fiber membrane 3 is at most about 55%, and a dead space of at least 45% is generated. Then, the active carbon 5 is filled into the dead space. Though the active carbon 5, other than fibrous one, granular and powder carbon or the like, is not especially limited, for example, the fibrous active carbon is dissolved in water, and flowed into the case 2 from an inflow side WO, and the active carbon 5 is filled in the dead space.

Abstract: PROBLEM TO BE SOLVED: To make provide with structure in which a positioning part of a module case and a regulating part such as a difference in level can be integrally formed and to increase pressure resistance strength without increasing the number of parts and the number of manufacturing processes and further without increasing the quantity of a filling adhesive. SOLUTION: On the inner periphery of an open end part of a module case 2 to which a patting part 5 is fixed, a regulating part such as a difference in level 7 protruded toward the inside of the module case 2 and for regulating the movement of the potting part 5 to the open end side in the axial direction is installed, and on the other hand, in the end part on the opposite side to the potting part 5 of the module case 2, a positioning part 8 on which bundles of hollow fiber membranes are abutted in the axial direction is integrally installed, and in at least a projected area in the axial direction of the regulating part of the positioning part 8, an opening 10 is installed.

Abstract: PROBLEM TO BE SOLVED: To provide a resin-made lip type seal being a plate-like lip bent centered on a point A of a tip of a substantially wedge-shaped recessed part and capable of reducing rigidity, reducing stress concentration at the point A to improve safety rate for destruction, suppressing reduction of sealing property due to reduction of creep, and improving following-up property for axis eccentricity. SOLUTION: Cut-in parts are formed on a slide-contact face 41 or/and an anti-slide-contact face 42 of the plate-like lip 4. A cut-in part 7 is also formed on an inclined slide-contact face 21 of an inner peripheral lip 2. A ratio of a part in which the cut-in part 7 is formed to surface area of the lip is 1/2 or more.

Abstract: PROBLEM TO BE SOLVED: To provide a humidifier wherein a hollow yarn membrane module can be mounted and dismounted with ease. SOLUTION: An end section 11, which is one of both ends 11 and 12 of the hollow yarn membrane module 10 to be mounted on the humidifier 1 and is mounted on a base material 20, is formed with a male thread on its external peripheral face. The base material 20 is provided with a recessed section 21 into which the end section 11 is inserted. The internal peripheral face of the recessed section 21 is formed with a female thread. The end section 12 to be mounted on a base material 30 has an external peripheral face not formed with a male thread. The base material 30 is provided with a recessed section into which the end section 12 is to be inserted. The internal peripheral face is also not formed with a male thread. In mounting the module 10 on both of the base materials 20 and 30, the end section 11 of the module 10 is inserted into the recessed section 21 while being threaded, and then the other end section 12 is pressed into the recessed section of the base material 30. A fixed shaft 40 comprises two shaft members 41 and 42 connected to each other. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module having a smooth surface formed at the time of molding, which is easy to manufacture. SOLUTION: Since a mold not having a positioning part or connection part provided heretofore and molding the axial region of the whole periphery of a module case 2 can be demolded from a unidirectional opening end by providing a frame 3 surrounding hollow fiber membrane bundles 4 inside the module case 2, the cylindrical module case 2 has a uniform wall thickness for obtaining a smooth surface and the smooth surface is obtained at the time of molding to facilitate the production of the module case 2 and the external peripheral shape of the module case 2 can be made circular to enable the effective utilization of a space.

Abstract: PROBLEM TO BE SOLVED: To provide a water purifying cartridge which is small-sized and has simple structure and in which granular activated carbon can be used and water can be purified satisfactorily by activated carbon treatment. SOLUTION: A housing chamber 23 for housing the granular activated carbon 3 is arranged on the upstream side of a flow path in the circular gap between an inside case part 21 and an outside case part 22. An introduction port 23a is arranged on one end side of the chamber 23 for introducing the untreated water into the chamber 23 and a discharge port 23b is arranged on the other end side for discharging the activated carbon-treated water to an intermediate chamber 24. Another introduction port 21a is arranged on the side surface of the part 21 for introducing the activated carbon-treated water, which is discharged to the chamber 24, into the part 21.

Abstract: PURPOSE: To provide a process for producing a high-quality U-shaped bundle of hollow-fiber membrane reduced in breakage at a low cost in high yield by mechanically bending the membrane instead of the handwork of an operator and to furnish the winder and fiber feeder of simple structure utilized in the process without need for an intricate synchronous system. CONSTITUTION: The winding and shaping machine for producing a bundle of hollow-fiber membrane is provided with a winding bobbin 23 revolving at a constant speed, a tension controller 32 for absorbing the variation of the traveling speed of the membrane and a feeder 41 for feeding a fiber 27 wound on a complete winding bobbin 42 by a guide member 45 arranged rotatably around the bobbin 42 in the axial direction of the bobbin 42 through the guide member 45.
