Patent number: 8519046Abstract: It is an object of the present invention to provide a polyolefin resin dispersion composition in which the dispersed resin is stable to water or a hydrophilic substance, and which has an adhesive property to nonpolar substrates, in particular poorly adhesive polyolefin-based substrates whose surface has not been treated, is excellent in a coating property, exhibits an excellent adhesive property through drying and press bonding with heat at a temperature in a wide range regardless of whether the temperature is low or high, is excellent in water resistance and gasohol resistance and is less tacky. That is, the present invention provides the dispersed resin composition containing (a) a polyolefin resin, (b) a (meth)acrylic acid homopolymer or copolymer having a side chain comprising an esterified alkyl group, (c) a basic substance and (d) water or a hydrophilic substance, and a process for producing the same.Type: GrantFiled: December 13, 2007Date of Patent: August 27, 2013Assignee: Nippon Paper Chemicals Co., Ltd.Inventors: Takayuki Hirose, Naosuke Komoto, Kensho Okayama, Koji Masumoto, Naoko Nagaoka

Patent number: 5420252Abstract: A novel human antithrombin III (AT III) mutant having a high antithrombin activity in the absence of heparin and effective in the treatment of thrombotic disorders as an anticoagulant, which is obtained by mutating amino acids at the reactive site and the heparin binding site of human AT III into another amino acids with the use of the recombinant DNA technology with the use of a DNA coding for AT III as a template. The invention also relates to a method for mass producing the above-described mutant by incubating a host transformed by an expression vector having the cDNA of the mutant inserted therein.Type: GrantFiled: April 9, 1993Date of Patent: May 30, 1995Assignee: Eisai Co., Ltd.Inventors: Hiroyuki Kato, Shinji Yoshitake, Suguru Suzuki, Noboru Suzuki, Toshio Seto, Naoko Nagaoka, Yoshiharu Mizui
