Patent number: 8344085Abstract: The present invention provides a novel polymer, and a mixture and a cement admixture thereof. The cement admixture has higher dispersibility compared to the previous ones. The novel polymer of the present invention has a different structure from the conventional copolymers used for cement admixtures, using an unsaturated carboxylic acid monomer and an unsaturated polyalkylene glycol monomer as the monomer components. The novel polymer of the present invention basically contains a polyalkylene glycol chain and a polymer segment bonded to the chain. Another type of the novel polymer of the present invention contains two polyalkylene glycol chains and a polymer segment connecting the chains. In these polymers, at least one of unsaturated monomers constituting the polymer segment is an unsaturated carboxylic acid monomer or an unsaturated polyalkylene glycol monomer. The cement admixture of the present invention comprises a polymer, made from these monomers, or a mixture thereof.Type: GrantFiled: November 3, 2010Date of Patent: January 1, 2013Assignee: Nippon Shokubai Co., Ltd.Inventors: Tsutomu Yuasa, Noboru Sakamoto, Yuko Matsuda

Patent number: 8133212Abstract: In a disposable diaper, the crotch region is divided by a front folding guide and a rear folding guide into a front section, a rear section and an intermediate section. The crotch region is provided on the side of its inner surface with a pair of contracting members extending in a longitudinal direction and spaced from each other. Front portions of the respective contracting members are fixed to the inner surface of the diaper in positions anterior to a line bisecting a longitudinal dimension of the intermediate section, while rear portions of the respective contracting members are fixed to the inner surface of the diaper in positions posterior to the intermediate section, so that intermediate portions of the respective contracting members may be spaced from the inner surface of the diaper and elastically contractible in the longitudinal direction.Type: GrantFiled: March 23, 2007Date of Patent: March 13, 2012Assignee: Uni-Charm CorporationInventors: Naoko Takada, Hironao Minato, Yuko Matsuda, Yoshitaka Mishima
