    摘要: A graft-modified polyolefin resin is provided, which is obtained by preparing a aqueous suspension containing (a1) 100 parts by weight of a polyolefin resin, (a2) 0.1 to 30 parts by weight of a mixture of 1 to 1000 parts by weight of an unsaturated glycidyl ester to 100 parts by weight of a compound having a glycidyl group as represented by a general formula (I): ##STR1## wherein Ar is an aromatic hydrocarbon group of C.sub.6 -C.sub.23 having at least one glycidyloxy group, and R is a hydrogen atom or a methyl group, (a3) 0.1 to 500 parts by weight of a vinyl monomer, and (a4) 0.001 to 10 parts by weight of a radical initiator to 100 parts by weight in total of (a2) and (a3), to thus impregnate (a1) with (a2) and (a3), and polymerizing (a2) and (a3) onto (a1). Resin compositions containig the graft-modified polyolefin resin have not only well-balanced mechanical properties, but excellent moldability.

    摘要: A disk storage system with a RAID architecture includes a write buffer having a storage capacity corresponding to one stripe, a buffer management table, and a controller. The controller stores, in the write buffer, logical blocks whose data lengths are changed, as needed, and delays updating of the logical blocks stored in the write buffer in data update processing until the number of stored logical blocks reaches N*K−1 The controller then performs a continuous write operation to sequentially write N*K logical blocks, obtained by adding a logical address tag block to the N*K−1logical blocks, in contiguous areas of empty areas different from the areas in which the old data are stored.

    摘要: A resin composition which includes (A) 100 parts of a blend of a polyacrylate and a poly(alkylene-phenylene ester) and (B) 1-50 parts of a chemically modified polyolefin copolymer exhibits superior impact resistance, particularly low temperature impact resistance, while retaining good melt viscosity for molding. The polyacrylate may be produced by polymerizing a dihydric phenol formula I: ##STR1## with an aromatic dicarboxylic acid, a dichloride derivative, an alkylated derivative or an arylated derivative thereof. The chemically modified polyolefin copolymer has a structural unit containing at least one amide group at and at least one glycidyloxy or glycidyl group, with the number of the structural unit contained in the copolymer being one per from 4 to 5,000 carbon atoms of the polyolefin moiety.
