摘要： A process for preparing poly-.alpha.-amino acid particles comprising polymerizing an .alpha.-amino acid-N-carboxy anhydride using a polymerization initiator in an organic solvent in which both the solubility of the .alpha.-amino acid-N-carboxy anhydride and the solubility of the produced poly-.alpha.-amino acid are 0.1 g/100 ml or less at 25.degree. C. Polyamino acid particles having a high molecular weight and a small bulk specific gravity can be manufactured very easily without requiring specific procedures. The polyamino acid particles can be used as a coating material for papers, resins, rubbers, and fibers; particles for cosmetics; particles for diagnostic drugs; fillers for chromatography; and an encapsulating material for drugs, fertilizers, and perfumes.

摘要： A process for the preparation of highly crosslinked polymer particles from polymerizable vinyl monomers comprising 15% by weight or more of a crosslinking vinyl monomer. The process comprises: providing an organic solvent, a mixture of organic solvents, or a mixture of at least one organic solvent and water which can dissolve the polymerizable vinyl monomers but cannot dissolve the polymer which is produced by the polymerization of the polymerizable vinyl monomers, the solubility in water of the polymerizable vinyl monomer being not more than 30% by weight, dispersing the polymerizable vinyl monomers into the organic solvent, the mixture of organic solvents, or the mixture of the at least one organic solvent and water, and polymerizing the polymerizable vinyl monomers in the presence of a dispersion stabilizer and a radical polymerization initiator. The crosslinked polymer particles have a comparatively uniform particle size within the particle size range of 0.1-10 .mu.m. They are useful as a slip property improver for plastic films, a spacer for liquid crystal display devices, a carrier for chromatography, and a standard sample for microscopic examination.

摘要： It is an object of the invention to provide an aqueous dispersion for CMP that produces no scratches on polishing surfaces and that polishes with an adequate rate, when used for polishing of copper and the like. The aqueous dispersion of the invention contains water and polymer particles composed of a polymer with a specific functional group, and it may also contain a complexing agent, a compound that forms a passivation film on polishing surfaces and/or an oxidizing agent. The specific functional group is a functional group that can react with the metals of polishing surfaces or that can form a cation, and it is preferably selected from among amino, pyridyl and acrylamide groups. The polymer can be obtained using a initiator and/or monomer possessing the specific functional group. The polymer may also have a crosslinked structure.

摘要： A decoder that receives, as input, probability information AMP/CR×yt. This probability information is obtained by dividing a channel value obtained by multiplication of received value yt and a predetermined coefficient AMP by the first additive coefficient CR for regulating the amplitude of the received value yt and the probability information 1/CA×APPt obtained by multiplying the a priori probability information APPt by the reciprocal of the second additive coefficient CA for regulating the amplitude of the a priori probability information APPt to a soft-output decoding circuit. The soft-output decoding circuit, which may be a large scale intergrated circuit, generates log soft-output CI×Iλt and/or external information 1/CA×EXt using additive coefficients for regulating the amplitude of arithmetic operations in the inside of the soft-output decoding circuit.

摘要： The present invention relates to a decoding method and a decoder, a program, a recording-and-reproducing apparatus and a method, and a reproducing apparatus and a method that are suitable for decoding encoded data encoded by using a linear code on ring R. A low-density processing unit performs parity-check-matrix low-density processing, performs linear combination for rows of a parity check matrix included in an obtained reception word, and generates a parity check matrix according to the linear-combination result, thereby reducing the density of the parity check matrix used for decoding, at step S21. Then, at step S22, an LDPC decoding unit performs decoding by using a sum product algorithm (SPA) by using the parity check matrix whose density is reduced through the processing performed at step S21. Where the processing at step S22 is finished, the LDPC decoding unit finishes decoding for the reception word. The present invention can be used for an error-correction system.
