Publication number: 20110005605Abstract: The present invention provides a liquid delivery control method for delivering a liquid 8 by generating, in a microchannel 3 in which the liquid 8 is present, a differential pressure with respect to the liquid 8 by using a pump 6. The microchannel 3 is provided with a pressure loss varying portion 31 in which pressure loss changes in the direction of flow. The leading end 8a of the liquid 8 is judged to have reached the pressure loss varying portion 31 by detecting a change in pressure between the liquid 8 and the pump 6. With this arrangement, the location of the leading end of the liquid 8 can be properly detected without causing the structure that forms the microchannel 3 to become complex.Type: ApplicationFiled: March 27, 2009Publication date: January 13, 2011Applicant: ARKRAY, INC.Inventor: Masahiro Hanafusa

Patent number: 7857086Abstract: A working vehicle in accordance with the present invention is provided with an engine mounted on a front portion of a vehicle body frame constructing a traveling vehicle body, a backhoe arranged on a rear portion of the vehicle body frame, a mower device arranged below the vehicle frame, a seating detecting means detecting a seating of an operator in a control seat on the traveling vehicle body, an engine stop mechanism stopping the engine, and a shift control means for controlling so as to increase and decrease forward and backward moving speeds of the traveling vehicle body. Further, in consideration for a safety at a time of an excavating work by the backhoe, the structure is made such that the engine stop mechanism is actuated at a time of operating the shift control means in the case that the seating detecting means is in an on state, and the seating detecting means is retained to the on state regardless of the seating of an operator in the case that the control seat is directed backward.Type: GrantFiled: September 18, 2008Date of Patent: December 28, 2010Assignee: Yanmar Co., Ltd.Inventors: Kensaku Wakuta, Kazuhiko Miyamoto, Masahiro Hanafusa, Junko Shibaoka

Patent number: 5488469Abstract: A cell analyzing apparatus which employs flow cytometry to obtain the concentration (the cell count per unit volume) of a specimen under examination is adapted to measure either the cell count of a control specimen the concentration of which is known or the length of time the control specimen is measured. The concentration of the specimen under examination is calculated based upon the cell count thereof obtained over a length of measurement time identical with the length of measurement time of the control specimen. Alternatively, the concentration of the specimen under examination is calculated based upon the length of measurement time thereof needed to obtain a cell count identical with that of the control specimen.Type: GrantFiled: August 28, 1992Date of Patent: January 30, 1996Assignee: Omron CorporationInventors: Koji Yamamoto, Masahiro Hanafusa, Fumio Onuma, Michio Nishimura

Patent number: 5408307Abstract: In a cell analyze apparatus, a light beam is irradiated onto cells (or particles like the cells) flowing through a flow cell so as to measure cell light information for each cell with respect to a plurality of parameters (for example, the forward scattered light intensity, the right angle scattered light intensity and the intensity of fluorescence by different dye). Based on a minimal point of a histogram associated with the cell light information with respect to one or more parameters, the cell population is subdivided into fractions. When the minimal point is missing in the histogram, the parameters above are converted by use of a predetermined conversion expression (for example, a coordinate conversion is effected on the parameters) such that a minimal point is detected from the histogram of cell light information related to the new parameters obtained by the conversion, thereby subdividing an objective cell population.Type: GrantFiled: July 11, 1989Date of Patent: April 18, 1995Assignee: Omron Tateisi Electronics Co.Inventors: Koji Yamamoto, Masahiro Hanafusa, Michio Nishimura, Yoshihiro Nakatsuji, Fumio Onuma, Shinichi Hirako, Kunio Kaede
