Abstract: PURPOSE:To obtain plastic optical fiber having a core consisting of polymethacrylic ester having superior light transmitting characteristic by prepg. the core by block polymn. at a specified temp. CONSTITUTION:A monomer consisting essentially of methacrylic ester is mixed with additives in a mixing vessel 15 and the mixture 16 is charged to a polymn. vessel 1 and polymerized by circulating a heat medium introduced from an introducing hole 20. The polymn. temp. is elevated gradually from 90 deg.C to 200 deg.C, thus, a polymer having uniform quality and superior transparency is obtd. with conversion as high as >=90% by the block polymn. method. Obtd. core polymer is transferred to a spinning soln. tank 2 where volatile matters are removed out of a vent hole 10. Then, the spinning soln. tank 2 is upset and a piston 4 is pushed down to extrude the core polymer through a die 28. An opening 26 is provided to a die block 24 so as to permit simultaneous extrusion of a sheath polymer. The opening 26 is connected to a sheath polymer extruder 25.

Abstract: PURPOSE:To obtain a nonaqueous electrolyte secondary battery which is high in capacity, excellent in charging and discharge cycle characteristic and also excellent in safety. CONSTITUTION:In a nonaqueous electrolyte secondary battery using carbonaceous material as electrodes, paper with pulp as its main component or a combination of this paper and porous film is used for the separator. Accordingly, the short circuit between positive and negative electrodes due to fuzz of the carbonaceous material is perfectly prevented, so that rupture/ignition of the battery caused by rapid temperature rise due to the short-circuiting is prevented and the product ratis is raised.

Abstract: PURPOSE:To obtain optical transmission performance which is excellent in a visible to near IR region by using a polymer or copolymer as a core of a plastic optical fiber having core-cladding structure. CONSTITUTION:Deuterated pentafluorophenyl methacrylate, 0.1mol% azobis tert-butane and 0.1mol% n-butyl mercaptan are mixed in the substantial absence of dust and oxygen and are polymerized for 24hr at 130 deg.C in a hermetic system. After the unreacted monomers are removed under a reduced pressure, the copolymer is melt-extruded simultaneously with a cladding polymer by using a composite mouthpiece, by which the optical fiber is prepd. Spinning is executed at 220 deg.C and a copolymer of hexafluoropropyl methacrylate/MMA is used for the cladding material.

Abstract: PROBLEM TO BE SOLVED: To enhance removal performance of cation ions by dipping a composite semipermeable membrane provided with an ultra-thin membrane layer having cross- linked polyamide on a fine porous support membrane into a sodium hydrogensulfite solution, then specifying a resistivity holding ratio of permeated water when a NaCl solution is used as raw water. SOLUTION: In the composite semipermeable membrane provided with the ultra-thin membrane layer, which consists essentially of the cross-linked polyamide, having separation performance on the fine porous support membrane not having separation performance, the resistivity holding ratio when it treats with water under a specified condition, is set at >=80%. Thus, even in the case that the treating water contains an electrolyte, while removal performance of a solute is maintained, high water permeability is secured. Here, when a resistivity of the permeated water after immersion is >3 MΩ.cm, e.g. a recovery type ion exchange resin tower can be dispensed with. The composite semipermeable membrane housed in a desired container is used as a composite semipermeable membrane element. This membrane be applied to a reverse osmosis membrane device for which feed water contains carbonic acid and Na ion conentration is
