    摘要: Natural coal containing inorganic impurities may be deashed by the selective flocculation process using a novel flocculant which is a water-soluble or water-dispersible copolymer having a molecular weight from about 100,000 to about 30,000,000 comprising a hydrophilic monomeric unit having a solubility in water greater than 15% by weight at 20.degree. C. and a hydrophobic monomeric unit having a solubility in water less than 10% by weight at 20.degree. C. in proportions of 99:1 to 20:80% by weight.

    摘要: A process for forming a gel by gelling an aqueous solution of a water-soluble polymer with a chromium compound as a gelling agent, in which a copolymer of acrylamide, 0.5 to 40% by mole of an unsaturated sulfonic acid or its salt, and optionally an unsaturated carboxylic acid or its salt having an intrinsic viscosity of at least 10 in 1N-NaNO.sub.3 at 30.degree. C., is used as the water-soluble polymer, and which is availably applied to improvement of water-oil ratio in oil production and to civil engineering for preventing leakage of underground water. The formed gel is very stable in a water system containing salts in high concentrations at high temperatures.

    摘要: A host PC that creates image data used in an ink-jet printer capable of landing ink with a multi-pass method includes an image data creation means that creates the image data so that the ink-jet printer forms an image with a halftone dot which is configured so that a relationship between a pass number and a dot pitch in a vertical scanning direction of an ink-jet head does not become an integral multiple relationship when the pass number is odd number, and a dot pitch does not become even number when the pass number is even number.

    摘要: Disclosed is a polymer material of low relative permittivity obtained through copolymerization of a monomer composition that contains, as monomers, a fumaric diester and an epoxy group-having (meth)acrylate. The polymer material bonds or adheres well to metal conductor layers, and, after crosslinked, it is patternable. In addition, it has good electric properties of low relative permittivity, low dielectric loss tangent and good electric insulation, and has good heat resistance.
