摘要： PURPOSE:To simply and completely repair the leakage cutting at leaked part, after applying and pressurizing fluidizable adhesives on adhered tip face of hollow yarn opening end and invading in the leaked part and then, solidifying, at the module accomodating hollow yarn-shaped selective permeable membrane (hollow yarn membrane). CONSTITUTION:Fluidizable adhesives having 3-1000cp. preferably 100-1000cp. of viscosity on adhered tip face of hollow yarn opening end, is applied on the module accomodating hollow yarn membrane. Next, suitable box is provided on the tip face and closed vacant space is formed and then, pressing pressure is given on the adhesives supplying pressurized gas. Invaded adhesives is solidified pressurizing as it is or releasing pressure after the adhesive is fully invaded in leaked place. Then, adhered tip part is cut so as to be formed new hollow yarn opening end.

摘要： PURPOSE:To eliminate the disconnection of the liquid junction between an internal solution and an external solution to be inspected, by using a porous yarn, which comprises a hydrophilic polymer and of which the pore volume is a specific value or more, as the internal solution holder of a reference electrode. CONSTITUTION:A silver-silver chloride wire 7 is provided so as to be extended into a flexible fine tube 6, for example, a catheter and the leading end thereof is contacted with the porous yarn 8 received in the leading end of the tube 6. The silver-silver chloride wire and the porous yarn are fixed in the tube by a resin 9. The porous yarn 8 being the internal solution holder of a reference electrode comprises a hydrophilic polymer such as polyvinyl alcohol or an ethylene/ vinyl alcohol copolymer and requires a pore volume of 0.2cc/g or more. In thus constituted reference electrode, because the internal solution is held in the fine pores of the porous yarn and the silver-silver chloride wire is closely contacted with said solution and extended to a liquid junction port, there is no disconnection of the liquid junction between the silver-silver chloride electrode and a solution to be inspected.

摘要： PURPOSE:The porous hollow yarn film which is so arranged as to be able to perform air back washing well and obviate degradation in film performance by specifying the ratios of the mean pore sizes of the first region composed of micro pores and the mean pore sizes of the second region composed of relatively large fine pores within the specific range. CONSTITUTION:In the hollow yarn film having the porous structure having the first region arrayed with micro pores of mean pore sizes 0.01 to 5mum and the second regions composed of relatively large fine pores of mean pore sizes 0.5 to 20mum, more preferably 0.5 to 10mum, the ratios D2/D1 between the mean pore size D1 of the first region and the mean pore size D2 of the second region are preferably within the range of 5 to 100, more preferably 5 to 50 and the second region exists 3 to 40%, more preferably 3 to 30% in the hollow yarn film. The foregoing hollow yarn film may be produced by a wet method, dry method or their combinations from cellulose acetate base, polyacrylonitrile base, polyester base polymers, etc.

摘要： PURPOSE:To obtain a high pressure steam sterilizable chemical material measuring apparatus, by housing a chemical material inductive sensor comprising an electrode selectrively inductive to a specified chemical material and a liquid junction type reference electrode into one tube. CONSTITUTION:A gate section of a chemical material inductive sensor, for example, an ISFET 11 is producted at one hollow of a catheter 10 and an electrode section of the FET 11 is securely buried into a water resistant electrically insulating resin 12. A lead 13 is extended along the hollow and linked to a connector 14 at the other end opening of the catheter 10. A porous hollow fiber 15 is housed at the tip of the catheter 10. One end of a liquid junction type reference electrode, for example, a silver-silver chloride wire 16 is inserted into a space of the hollow fiber 15. The silver wire 16 is extended along the hollow and linked to the connector 14. Thus, a high pressure steam sterilizable chemical material measuring apparatus can be obtained.

摘要： PURPOSE:To obtain a polyvinyl alcohol polymer membrane excellent in dimensional stability at the time of wetting, by acetifying the OH-group of a polyvinyl alcohol polymer with specific long-chain dialdehyde to introduce three-dimensional cross-link into said group. CONSTITUTION:A separation membrane is formed at first from a polyvinyl alcohol polymer. Subsequently, the separation membrane is immersed in an acetifying reaction bath comprising an aqueous solution containing dialdehyde represented by formula (wherein n is an integer of 7-10), for example, nonane diol, sulfuric acid and sodium lauryl sulfate and reaction temp. and time are regulated to bring the acetifying ratio of the separation membrane to 5-60mol%. By this method, the separation membrane containing the polyvinyl alcohol polymer as a base material excellent in dimensional stability is obtained while characteristics such as heat resistance, hot water resistance and strength are sustained.
