Patent number: 7847047Abstract: A material which expresses its critical solution temperature even in an aqueous solution containing a buffer or salt, and at the same time, shows small variation width of the critical solution temperature even when concentration of salt or the like contained in water, a buffer liquid or the like is different, interacts with a substance such as a component in the living body and can therefore be used efficiently in the isolation of substances, is provided. A monomer represented by a formula (1) and a thermoresponsive polymer which contains said monomer as a polymerization component.Type: GrantFiled: February 27, 2007Date of Patent: December 7, 2010Assignee: Chisso CorporationInventors: Hirokazu Nagaoka, Noriyuki Ohnishi, Masaru Eguchi

Patent number: 7306640Abstract: A vacuum cleaner includes a first dirt separation unit and a second dirt separation unit. The first dirt separation unit has a first inlet port through which a suction air stream including dirt particles is introduced thereinto, and the second dirt separation unit has a second inlet port through which the air stream introduced into the first dirt separation unit is introduced into the second dirt separation. The first and the second inlet port are disposed such that they are not registered with each other. Accordingly, the dirt particles suctioned are separated in two stages, thereby decreasing the possibility of occlusion of a filter and rapid deterioration of a suction force.Type: GrantFiled: October 23, 2003Date of Patent: December 11, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshiki Kuroki, Seiji Yamaguchi, Tomonori Kato, Masashi Okushima, Yuichi Shimizu, Tomomi Mitani, Hiroshi Mori, Toru Odachi, Yoshiaki Onishi, Hidenori Kitamura, Toshifumi Miyahara, Takaaki Ogawa, Hirokazu Nagaoka
