Patent number: 8647589Abstract: An object of the invention is to provide various flow cells and a method for manufacturing the same, in which formation of a groove on a substrate and formation of components such as an electrode, auxiliary parts such as a pump are not necessary. The inventive flow cells are capable of realize complicated chemical analysis or synthesis or the like. A channel of a porous member provided on a sample-incompatible substrate is formed; the porous member is composed of an air non-contact region having a network structure and an air contact region covering the air non-contact region and having a lower pore density than the air non-contact region; in which a capillary force to be generated within the porous member is a drive force for pumping a liquid.Type: GrantFiled: July 20, 2012Date of Patent: February 11, 2014Assignee: Nippon Telegraph and Telephone CorporationInventors: Tsutomu Horiuchi, Toru Miura, Yuzuru Iwasaki, Jyunichi Takahashi, Katsuyoshi Hayashi, Tsuneyuki Haga, Michiko Seyama, Serge Camou

Patent number: 8263025Abstract: Ends (134a-1) of projections (134a) do not contact a first substrate (11), forming a gap between the ends (134a-1) and the first substrate (11). The internal capacity of a suction pump (17) can be increased by an amount by which the projections (134a) are shortened, compared to a conventional structure in which pillars are formed to connect the ceiling and bottom of the cavity of a capillary pump. The capacity of the suction pump (17) can be increased without enlarging the planar shape. Further, the ends (134a-1) of the projections (134a) do not contact the first substrate (11), forming a gap between them. An impurity can pass through the gap, and clogging of the inside of the suction pump (17) with the impurity can be prevented, realizing a stable operation.Type: GrantFiled: January 30, 2009Date of Patent: September 11, 2012Assignee: Nippon Telegraph and Telephone CorporationInventors: Toru Miura, Tsutomu Horiuchi, Yuzuru Iwasaki, Michiko Seyama, Serge Camou, Tsuyoshi Hayashi, Jun-ichi Takahashi

Patent number: 7259849Abstract: There is provided an optical system 8 for a micro analyzing system capable of precisely analyzing a sample. In the optical system 8, after light beams leaving the tip of an optical fiber 14 pass through a condensing part 13, a sample moving in a separation passage 6 due to electrophoresis is irradiated with the light beams. The condensing part 13 includes a first aspherically cylindrical surface 10 being convex toward the optical fiber 14, a second aspherically cylindrical surface 11 being convex on the opposite side to the first aspherically cylindrical surface 10, and a third aspherically cylindrical surface 12 being convex toward the second aspherically cylindrical surface 11. The first through third aspherically cylindrical surfaces 10 through 12 are arranged in that order from the side of the optical fiber 14 toward the separation passage 6.Type: GrantFiled: June 2, 2004Date of Patent: August 21, 2007Assignee: Enplas CorporationInventors: Koichi Ono, Teruo Fujii, Serge Camou
