Abstract: There is provided a method for producing a chamber frame for a dialyzer, which is readily produced, has a stable quality, is inexpensive and is excellent in sealing property and heat resistance. A cut frame 1 is set on an unshown table of an impulse welder 30, distributors 13 are fitted into communicating passage 9 and communicating passages 11, and a net 15 is positioned so as to cover a central opening 3. Welded portions A and B, and the welded portions C and D are subjected to impulse welding. Mounting of the net 15 as a spacer and mounting of the distributors 13 are carried out simultaneously by a single pressing operation. After that, the welded portions of the net are deburred, and correction work is performed on defects.

Abstract: A clamping device for a dialyzer includes a holding member having a supply port and a discharge port for permitting a liquid to be treated to flow through the desalination chambers and the concentration chambers; a clamping member for clamping the holding member by a certain clamping pressure; a lattice structure having a contact portion configured to be brought into contact with an electrode frame or be brought into contact with an electrode frame through a certain plate-shaped member such that the clamping member clamps the electrode frame, the chamber frames and the exchange membranes through the contact portion by tightening the clamping members; and the lattice structure having a pitch width of at least 10 mm and at most 50 mm.

Abstract: To provide a moisture control module which has a function to reduce or increase moisture in a gas permitted to flow in a hollow fiber and which is substantially free from air leakage and easy to produce; a process for producing such a moisture control module; and an apparatus for producing such a moisture control module. A moisture control module comprising a tubular hollow fiber 1, a braid fiber 3 plaited into a braid to cover the exterior of the hollow fiber 1, and a pipe 5 inserted in an end of the hollow fiber 1, wherein as the hollow fiber 1 and the braid fiber 3 present in a region with a prescribed length from said end have been heated at a prescribed temperature from outside, the braid fiber 3 is fused, and at the same time, the hollow fiber 1 is fixed by heat shrinkage to the pipe 5.

Abstract: In order to solve various problems such as a reduction in a paint resin with the progress of electrodeposition coating treatment and remelting of a coating film or the occurrence of pinholes caused by an increased concentration of an electrolyte as a result of the reduction, upsizing of a hollow electrode with a membrane for electrodeposition coating combined with a barrier membrane (e.g., an ion exchange membrane) and an increase in the number of components should be avoided. In order to realize this, a barrier membrane 20 such as an ion exchange membrane is attached to the exterior surface of an electrode main body 10, which is in a hollow state made of a conductive material and configured so as to allow a liquid to pass through freely between the inside and outside of the electrode serving as a support.
