Patent number: 10246675Abstract: A cartridge sealed from ambient air is used to send a liquid without causing the liquid to contact the fluid inside the cartridge. Inside of the cartridge 1 sealed from ambient air are provided chambers that send and receive reagents, and an elastic body membrane 51 is attached to the bottom surface. The cartridge main body 51 does not have a groove or anything else that becomes a channel, and the membrane 51 is not bonded to portions that become channels. A channel, not formed in a normal state, is formed upon deforming the membrane 51 under air pressure in the unbonded portion, and the fluid is moved inside. A valve function is provided at an inlet of each chamber, and the fluid is internally moved in any direction with channel deformation.Type: GrantFiled: January 27, 2014Date of Patent: April 2, 2019Assignee: Hitachi High-Technologies CorporationInventors: Ryusuke Kimura, Hiromi Yamashita, Motohiro Yamazaki, Taro Nakazawa

Patent number: 9415391Abstract: A cartridge sealed from an external air is used to enable mixing with a reagent, agitating, purification, reaction, etc. Provided inside the cartridge sealed from the external air are a chamber for the reagent to be transported, a chamber to which the reagent is transported, and the chambers are connected by a liquid transport channel. A groove is made in a cartridge body and a membrane as an elastic body is pasted onto the groove to form the liquid transport channel. Air pressure is given to the membrane to change the volume of the liquid transport channel and thereby move the fluid inside. The inlet of each chamber has a valve function to move the fluid inside in a desired direction according to change of the liquid transport channel. This enables transportation of the liquid inside the cartridge sealed from the external air.Type: GrantFiled: June 18, 2013Date of Patent: August 16, 2016Assignee: Hitachi High-Technologies CorporationInventors: Ryusuke Kimura, Hiromi Yamashita, Motohiro Yamazaki

A groove is made in a cartridge body 30 and a membrane 31 as an elastic body is pasted onto the groove to form the liquid transport channel 36. Air pressure is given to the membrane 31 to change the volume of the liquid transport channel 31 and thereby move the fluid inside. The inlet of each chamber has a valve function to move the fluid inside in a desired direction according to change of the liquid transport channel. This enables transportation of the liquid inside the cartridge sealed from the external air so that mixing with the reagent, agitating, purification, reaction, etc. can be performed in the cartridge.Type: ApplicationFiled: June 18, 2013Publication date: June 4, 2015Inventors: Ryusuke Kimura, Hiromi Yamashita, Motohiro Yamazaki

Patent number: 8685220Abstract: The invention provides a capillary electrophoresis apparatus which can improve the operability and measuring speed. According to the invention, a sensor for identifying the type of sample containers is fixed at the position away from a capillary anode electrode. The sensor is made to be closer to the sample containers by moving a moving stage so that the sample containers disposed on the moving stage can be identified by the sensor. A fixing apparatus for fixing at least a pair of sample containers is provided on the moving stage.Type: GrantFiled: July 26, 2012Date of Patent: April 1, 2014Assignee: Hitachi High-Technologies CorporationInventors: Takeshi Ohura, Ryoji Inaba, Yoshitaka Kodama, Hiromi Yamashita, Manabu Akiba, Tomohiro Shoji

Publication number: 20120219473Abstract: A sample rack 1 in which sample holding container 6 containing sample liquid is loaded and cooled via a cooling device 8 includes containing sections 40 adapted to receive the sample holding containers 6, and groove portions 11 disposed with inclination below the bottom surface of the containing section 40. The bottom surface of the containing section 40 communicates with the groove portion 11. The dew condensation water introduced into the groove portion 11 is discharged to the outside of the sample rack 1 via an opening portion 12 provided on the side surface of the sample rack 1. In this way, since the dew condensation water is forcibly discharged, workability encountered during removal of the sample rack and sample cooling capacity can be improved.Type: ApplicationFiled: October 29, 2010Publication date: August 30, 2012Applicant: HITACHI HIGH-TECHNOLOGIES CORPORATIONInventors: Kimihiko Ishii, Mitsuhiko Ueda, Shoji Tomida, Akira Kuroda, Hiromi Yamashita

Patent number: 7883613Abstract: The present invention provides a capillary electrophoresis apparatus in which a capillary is easily attached to and detached from a migration medium filling unit without mixing impurities into the capillary. Mixture of impurities such as dust is also prevented when a capillary negative-electrode end is brought into contact with a sample stored in a vessel. Furthermore, temperature control is efficiently performed in the capillary. In the capillary electrophoresis apparatus, the whole of capillary array can be supported by grasping a grip portion by hand. A migration medium filling mechanism includes a slide mechanism which moves a polymer block with respect to a capillary head. The capillary electrophoresis apparatus includes a vessel in which a sample and a buffer can simultaneously be stored. Temperatures of the capillary and an irradiation and detection unit are controlled by a temperature control function provided in a thermostatic device.Type: GrantFiled: June 5, 2007Date of Patent: February 8, 2011Assignee: Hitachi High-Technologies CorporationInventors: Takashi Gomi, Ryoji Inaba, Motohiro Yamazaki, Hidenori Namba, Jin Matsumura, Hiromi Yamashita, Seiichi Ugai, Kazumichi Imai

Patent number: 7662269Abstract: The troublesomeness during the setting of a plurality of capillaries is eliminated by composing pairs of electrodes, which are electrically connected to the common electrode, and capillaries. By bringing electrodes installed in the vicinity of each capillary disposed at the pitch of wells on the side of sample plate (within the area of the wells) into electrical contact with a common electrode, the capillaries and electrodes are made integral in construction. When a voltage is applied to the electrophoretic instrument via a common electrode portion, the voltage is applied to the electrodes for each capillary. This enables an inexpensive microtiter plate, etc. to be used and a multiple of capillaries to be simultaneously inserted, attached and detached.Type: GrantFiled: January 23, 2009Date of Patent: February 16, 2010Assignee: Hitachi, Ltd.Inventors: Muneo Maeshima, Kazumichi Imai, Masaya Kojima, Satoshi Takahashi, Hiromi Yamashita
