摘要： PURPOSE:To simultaneously perform an aerobic reaction and an anaerobic reaction for the simplification of water clarification, etc., by employing a biocatalyst-immobilized gel consisting mainly of polyvinyl alcohol in which aerobic bacteria are immobilized at the neighborhoods of the surface and in which anaerobic bacteria are immobilized at the neighborhoods of the center. CONSTITUTION:An aerobic reaction and an anaerobic reaction are simultaneously carried out in the presence of a biocatalyst-immobilized gel for the treatment of waste water, the clarification of culture water, etc. The biocatalyst- immobilized gel is produced by immobilizing aerobic bacteria in the neighborhoods of the surface of a gel and immobilizing anaerobic bacteria in the neighborhoods of the center. The gel comprises polyvinyl alcohol therein having a point having the shortest distance of >=2mm between the point and the surface.

摘要： PURPOSE:To obtain a high performance flexible hose excellent in high pressure resistance, low expansibility, heat resistance, hot water resistance and fatigue resistance by using a specific PVA fiber as a reinforcing material. CONSTITUTION:An oil brake hose has a two-layer structure in order to secure safety even when one layer is destructed. Since the inner layer braid system being the first layer largely contributes to the capacity of the hose, a high performance PVA fiber is pref. used at least in the first layer. By using the high performance fiber formed from a specific PVA polymer as a reinforcing material, the difficult point of hot water resistance from the aspect of the process at the time of the manufacturing of the hose is reduced and, further, the capacity of the hose can be also enhanced. As properties to be equipped, tensile strength is 15g/d or more, the initial modulus of elasticity is 250g/d or more, the strength retentivity of the fiber due to hot water of 120 deg.C after constant length heat treatment is 80% or more and the polymerization degree of PVA is 3,000 or more.

摘要： PURPOSE:To camouflage against far infrared ray by employing a plastic film having on its surface depressions or protrusions having a specified average depth or height, and setting the average value of the straight transmissivity of far infrared ray less than a specified percentage. CONSTITUTION:The anti-far infrared ray camouflaging film comprises a plastic film having on its surface depressions or protrusions having an average depth or height larger than 1mum, and its average value of straight transmissivity of far infrared ray is less than 20%. To form depressions or protrusions on the film surface, methods of embossing and making fine furrows are effective. When the spacing between the furrows is made less than 0.5mm, the straight transmissivity can substantially be reduced. It is important at this time that the depth of depressions or the height of protrusions is larger than 1mum. To form depressions or protrusions on the plastic film, such methods can be employed as causing the film to be pressed against the thermal roll having depressions or protrusions, or processing afterward by applying laser or plasma energy, or using saw-toothed nozzle for injection molding.

摘要： PURPOSE:To obtain the title gel having a negative surface potential and excellent flow, dispersibility, etc., by bringing liquid drops of an aqueous solution containing PVA and a specified water-soluble polymeric polysaccharide into contact with an aqueous solution containing a surfactant and cations to form spherical moldings and subjecting these moldings to a freeze and thaw operation. CONSTITUTION:An aqueous solution containing polyvinyl alcohol and a water-soluble polymeric polysaccharide (e.g. sodium alginate) having an ability to gel by contact with cations is prepared. Liquid drops of this aqueous solution are brought into contact with an aqueous solution containing a surfactant (e.g. water-soluble silicone oil) and cation-containing compound (e.g. calcium chloride) to mold the liquid drops into spherical moldings. These moldings are subjected to an operation comprising freezing to -5 deg.C and thawing from that temperature. In this way, hydrated spherical polyvinyl alcohol gel having a diameter >=1mm and a negative surface potential and being useful as a carrier for an immobilized biocatalyst for a bioreactor can be obtained.
