Title: Production of slurry composition and powder containing water-soluble polymer
Inventor: TSURUGA MASAHIRO
IPC: C08L39/02
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a method for powdering a water-soluble polymer, which, when powdered, needs no classification step and causing no problems, e.g. scattering of fine particles, and, when redissolved to be used as a coagulant or the like, causes no problems, e.g. lowered viscosity. SOLUTION: This method for producing a slurry composition containing a water-soluble polymer polymerizes a monomer containing N-vinyl carboxylic acid amide shown by the formula CH2=CHNHCOR (R is hydrogen or an alkyl), hydrolyzes the polymer with an acid, and incorporates the hydrolysis product with a basic compound at a temperature T( deg.C) in the following range: -2.26W<=T<=-2.26W+89 (W is content (%) of volatiles the water-soluble polymer contains while the hydrolysis product is being incorporated with the basic compound). The method for producing the polymer composition removes the solvent from the slurry composition, to produce the powder containing the water-soluble polymer.

Title: Metal crucible of floated melting apparatus
Inventor: TAKE TATSUO
IPC: F27B14/00
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent a contamination of a molten metal in a crucible, to increase a ratio of a magnetic flux interlinked with a material to be molten to a total magnetic flux generated in an induction coil, and to improve a melting efficiency by narrowing slits at inner and outer peripheral sides of a metal crucible, and broadening their intermediate portion. SOLUTION: The metal crucible comprises segments 9 partitioned by slits 8 narrowed in widths at inner and outer peripheral sides and broadened in a circular section at their intermediate portions, and cooling water passing channels 3 provided substantially at centers of the segments 9. Since the silts 8 are broadened at the intermediate parts, its magnetic reluctance of the slit is reduced so that a magnetic flux is easily penetrated into the crucible, and hence the flux interlinked with a molten material is increased. An eddy current induced in the material generates a Joule heat with an electric resistance of the material to heat to melt the material.  Thus, since the widths of the slits of the inner peripheral side of the crucible are narrowed, an exposed area of an insulator 10 of an inner surface of the crucible is decreased, and hence a contamination caused by a contact of the insulator 10 with the molten metal in the crucible can be suppressed.
