Patent number: 8481330Abstract: Disclosed is a method for analyzing a sample solution, including introducing a sample solution 50 through a sample introduction part 6 and developing the sample solution 50 to a developing layer 2 through a capillary phenomenon to analyze an analyte contained in the sample solution 50, the sample introduction part 6 being provided on one side of a test strip 100 and the developing layer 2 being provided on the other side of the test strip 100, wherein the test strip 100 is disposed in such a development posture that the downstream region of the developing layer faces downward during the development. By this method, the developing rate is less susceptible to the viscosity of the sample solution 50 and thus has a small difference even among sample solutions 50 differing in viscosity. As a result, the analytical accuracy and reliability can be improved.Type: GrantFiled: January 9, 2009Date of Patent: July 9, 2013Assignee: Panasonic CorporationInventors: Yoko Matsuda, Mie Takahashi, Masahiro Aga, Hideyuki Kurokawa, Takahiko Tanida, Ryosuke Yamada

Patent number: 8345249Abstract: Provided is a liquid sample analyzing method for analyzing an analyte in a liquid sample by using a test piece (1) on which overflow blocking lines (7) are formed to prevent the liquid sample from flowing to the outside from a passage region (3a) of an extended layer (3). In a state in which the liquid sample is not extended in the passage region (3a) of the extended region (3), the test piece (1) is measured so as to cross the passage region (3a) of the extended layer (3) and the overflow blocking lines (7). Thus in a state in which a difference in brightness is large between the passage region (3a) of the extended region (3) and the overflow blocking lines (7), it is possible to properly recognize the boundary portions between the passage region (3a) of the extended region (3) and the overflow blocking lines (7).Type: GrantFiled: March 26, 2009Date of Patent: January 1, 2013Assignee: Panasonic CorporationInventors: Hideyuki Kurokawa, Koji Miyoshi, Masahiro Aga, Kenji Murakami, Takahiko Tanida, Ryosuke Yamada

Patent number: 8310678Abstract: Provided is a device in which light from a sample 7 fixed in a test piece 1 is captured by an image sensor 5 through an optical system made up of a lens 3, a diaphragm 4, and so on and concentration information is obtained, wherein a wide-band light source 12 for illuminating the test piece 1 is combined with an optical filter 13 for optionally selecting a wavelength of the light captured by the image sensor. Thus it is possible to reduce a measurement error caused by a change of the light quantity distribution of the light source 12.Type: GrantFiled: January 22, 2009Date of Patent: November 13, 2012Assignee: Panasonic CorporationInventors: Ryosuke Yamada, Masahiro Aga, Koji Miyoshi, Kenji Murakami, Hideyuki Kurokawa, Takahiko Tanida

Patent number: 7974790Abstract: A particulate determination method determines by onetime scanning, the size of a particulate included in a plurality of particulates of various sizes which are arranged on a disc. False recognition of the number of particulates is avoided even when a plurality of particulates are adjacent to each other. A photodetector detection signal is judged using plural threshold values according to the sizes of particulates to be detected. Results of determinations corresponding to the respective threshold values are stored on mutually independent memory maps. When counting particulates, a particulate size and a particulate count value are determined from a combination of stored data appearing in a scanning window at the same position on the respective memory maps.Type: GrantFiled: June 19, 2008Date of Patent: July 5, 2011Assignee: Panasonic CorporationInventors: Junji Tada, Hideyuki Kurokawa, Yoshiyuki Fujii

Patent number: 4883185Abstract: A suspension type transporter suspends a bolt drawing machine through a trolley and a hoist above a pressure container having many bolt attached thereto and transports the bolt drawing machine to a target position. A track settling portion having a guide is provided on an outer periphery of a lid of the pressure container. The suspension type transporter for the bolt drawing machine comprises a guide mechanism which restricts movement of the bolt drawing machine in the air by the guide. The guide mechanism of the transporter is provided with a position detector which can detect a position of the bolt drawing machine. A positioning controller of the suspension type transporter controls the transporter so that the transporter starts at slow speed, is then accelerated to a prescribed speed and is gradually decelerated near the target position.Type: GrantFiled: November 2, 1987Date of Patent: November 28, 1989Assignees: The Hokkaido Electric Power Co., Inc., The Kansai Electric Power Co., Inc., Shikoku Electric Power Co., Inc., Kyushu Electric Power Co., Inc., The Japan Atomic Power Company, Mitsubishi Jukogyo Kabushiki Kaisha, The Japan Steel Works, Ltd.Inventors: Takashi Fujitani, Hiromi Uemura, Toshiaki Kishimoto, Masayuki Uchiyama, Isao Shirasu, Hideyuki Kurokawa, Takashi Nishioka, Kenji Kikukawa, Yoshinori Sato
