Publication number: 20160214875Abstract: This water treatment system includes a water intake section 8 for taking in a raw water containing a water-soluble polymer; a stirring unit 1 for stirring the raw water flowing into the unit from the water intake section 8; a separating unit 2 for separating a solid from the raw water after the stirring; a viscosity measuring section (5,6,50) for measuring the viscosity of the raw water flowing in the stirring unit 1, and that of the raw water after the stirring; and a control unit 4 in which on the basis of a result measured through the viscosity measuring section and a predetermined target viscosity, a control is made about the amount of an additive to be charged into the stirring unit 1, and/or the stirring intensity of the stirring unit. Thus, the viscosity of the raw water is adjusted.Type: ApplicationFiled: September 22, 2014Publication date: July 28, 2016Applicant: HITACHI, LTD.Inventors: Shigeki TERUI, Takashi YAMAGUCHI, Yasuyuki YAGI, Kiyokazu TAKEMURA

Patent number: 8263334Abstract: According to an aspect of the present invention, a pair of oligonucleotide strands are anchored onto the surface of a substrate by immobilizing one of the ends thereof onto the substrate. Each of the immobilized oligonucleotide strands is bound to a target nucleic acid sequence (single-stranded) having complementary sequences thereto to form a cross-linked structure on the substrate, thereby forming a finely reticulated space. Ligands are captured by this reticulated space through physical adsorption and caused to color with active substances reactive to the ligands. As a result of this, the present invention is capable of highly sensitively detecting even an exceedingly small concentration of a particular target nucleic acid sequence to be detected, at low cost and for a short time.Type: GrantFiled: March 18, 2011Date of Patent: September 11, 2012Assignee: Hitachi Plant Technologies, Ltd.Inventors: Hajime Ikuta, Kiyokazu Takemura

Patent number: 7992724Abstract: To reuse support plate and to fix a membrane sheet by the same method both in a new product manufacturing and in regeneration. In a flat membrane element including a deposit fixed portion formed by lapping a membrane sheet performing solid-liquid separation onto a support plate supporting the membrane sheet and by emitting a laser to a circumferential edge of the membrane sheet to deposit fix the member sheet onto the support plate, and making an inside of the membrane sheet surrounded by the deposit fixed portion be a solid-liquid separating area; an embrocation having laser absorption property is applied on the surface of the membrane sheet of the deposit fixed portion. At the time of regeneration, such a portion of the membrane sheet that corresponds to the solid-liquid separating area is cut off and, after that, a new membrane sheet is lapped on the embrocation and the new membrane sheet and the embrocation are deposit fixed by a laser.Type: GrantFiled: March 20, 2009Date of Patent: August 9, 2011Assignee: Hitachi Plant Technologies, Ltd.Inventors: Kiyokazu Takemura, Kazuhiko Noto, Mitsuru Hatanaka, Takashi Fujimoto, Tatsuaki Tagashira
