摘要： PROBLEM TO BE SOLVED: To obtain the subject binder capable of manifesting a good adhesive strength, etc., to a powdery electrode material and a collector with a small amount thereof used by using a sulfonated polyvinylidene fluoride-based resin as a binder. SOLUTION: This nonaqueous binder for a battery or a cell is obtained by sulfonating a polyvinylidene fluoride-based resin comprising a homopolymer of vinylidene fluoride or a copolymer of the vinylidene fluoride and a fluorine- containing monomer copolymerizable with the vinylidene fluoride such as vinyl fluoride, trifluoroethylene or chlorotrifluoroethylene. The polyvinylidene fluoride- based resin preferably has 0.5-10.0 intrinsic viscosity. The sulfone groups to be introduced may further be converted into a salt of lithium ion. A solution containing the binder dissolved in an organic solvent can be mixed with a powdery electrode material to provide an electrode mixture.

摘要： PROBLEM TO BE SOLVED: To obtain the subject reductive drug which can decrease the concentration of parathyroid hormone in blood and/or the concentration of phosphorus and affords little phytotoxicity such as side effect and the like by using spherical activated carbon as an active ingredient. SOLUTION: The objective reductive drug is obtained by using spherical activated carbon as an major ingredient. It is desirable that the spherical activated carbon is excellent in adsorption ability and processes the diameter of preferably 0.05-2 mm, the specific surface area of preferably 500-2,000 m /g and the void volume which contains pores of which radii are 100-75,000 angstrom in an amount of 0.01-1 ml/g. The above reductive drug is useful as a phosphorus reductive drug and further can decrease the concentration of parathyroid hormone in blood and the concentration of phosphorus at the same time. The daily dosage in human is usually 0.2-20 g as the amount of spherical activated carbon. The spherical activated carbon can be produced by carbonizing raw materials for activated carbon (sawdust, coal, organic synthetic polymer, etc.), followed by activation. As the method of activating, steam activation, medicinal activation, air activation or carbon dioxide activation can be used.

摘要： PROBLEM TO BE SOLVED: To make it stable to nonaqueous electrolyte, and improve adhesive strength to a current collecting base body by containing a hydrofluoric acid by a specific quantity to weight of a vinylidene fluoride polymer dissolved in an organic solvent, and also adding an acid except for the hydrofluoric acid. SOLUTION: A vinylidene fluoride polymer is dissolved in an organic solvent, and a nonaqueous battery forming binder solution is adjusted. A hydrofluoric acid of 400 to 20000ppm is contained to weight of a vinylidene fluoride polymer in this binder solution. An acid except for the hydrofluoric acid is also added. The formation of the hydrofluoric acid is promoted by heating a vinylidene fluoride solution or addition of alkali. An organic acid is used as the acid except for the hydrofluoric acid. Electrode mix slurry for a nonaqueous battery is obtained by dispersing a powdery electrode material in this vinylidene fluoride polymer binder solution. This slurry is applied on a current collecting base body, and is dried, and is formed as an electrode structure body having an electrode mix layer.

摘要： PROBLEM TO BE SOLVED: To provide a lid member whose specific gravity is small, which is excellent in molding property, transparency and dimension stability and which has a visibility correction function by copolymerizing a monomer containing a specified phosphate group and mixed monomer with a monomer which can be copolymerized with the monomer and containing an ionic metal component in it. SOLUTION: The monomer containing phosphate group represented by a formula I is copolymerized with the monomer which can be copolymerized with the monomer. Then, an acrylic copolymer whose hygroscopic property is small and which is superior in heat resistance, dimension stability and adhesive strength against a package is obtained. Here, the group R of the formula I is polymerized functional group shown by a formula II and (n) becomes '1' or '2'. Then, X in the formula II shows a hydrogen atom or a methyl group, and (m) is the integer of 0-5. The ionic metal group whose main component is set to be copper ions is contained in the acrylic copolymer which is thus obtained at an appropriate rate. Consequently, the lid member absorbing the liquid of a near-infrared area at high efficiency and having a satisfactory visibility correction function is obtained.

摘要： PROBLEM TO BE SOLVED: To permit a soft magnetic composite material to have an appropriate magnetic permeability and high insulating characteristic by making the average grain diameter of a magnetic powder obtained by pulverizing sintered magnetic body double the average crystal grain diameter of the sintered magnetic body or more. SOLUTION: The electric resistance of a resin composition (composite material) of a magnetic powder and a polymer reduces as the average grain diameter of a magnetic powder is reduced. An appropriate magnetic permeability and withstand voltage can be obtained by diffusing the magnetic powder, having an average grain diameter of double the average crystal grain diameter of the sintered magnetic body or more, into the polymer in pulverizing the sintered magnetic body.
