Patent number: 7198906Abstract: Disclosed herein is a method for determining the drug sensitivity of a microbe which comprises pouring a microbial suspension into each of the compartments or wells at a position which is in the vicinity of an electrode for measuring dissolved oxygen concentration, measuring current from each electrode at a second time interval for a third time period, each time is obtained based upon each of the measured currents at which the maximum current is obtained, obtaining each current value within a fourth time period which starts from the time at which the maximum current is obtained, detecting drug sensitivity based upon the variation condition of each current value during the fourth time period. The method allows rapid drug susceptibility measurements.Type: GrantFiled: March 19, 2001Date of Patent: April 3, 2007Assignees: Jikei University School of Medicine, Japan as Represented by Director-General of National Institute of Advanced Industrial Science and Technology, Ministry of Economy, Trade and Industry, Daikin Industries, Ltd.Inventors: Katsuhiko Machida, Sadayori Hoshina, Takashi Ushida, Junichiro Arai, Hideo Katayama, Chiaki Okumura, Yoshihisa Amano

Patent number: 7081353Abstract: A method and apparatus wherein measurement current values output from a first oxygen sensor and a second oxygen sensor are time sequentially measured. Each moving average value is calculated from each sequential measurement current value. Each time differential value is calculated from the pair of each calculated moving average values, by least squares approximation. Then, drug susceptibility is measured based upon each calculated time differential value, so that drug the susceptibility measurement is performed quickly or accurately.Type: GrantFiled: March 20, 2001Date of Patent: July 25, 2006Assignees: Jikei University School of Medicine, Japan as Represented by Director-General of National Institute of Advanced Industrial Science and Technology, Ministry of Economy, Trade and Industry, Daikin Industries, Ltd.Inventors: Katsuhiko Machida, Sadayori Hoshina, Takashi Ushida, Junichiro Arai, Hideo Katayama, Chiaki Okumura, Yoshihisa Amano

Patent number: 6452140Abstract: A substance 6 is located in a gradient magnetic field and held in a levitating state by a magnetic force produced by the gradient magnetic field. The substance 6 as such in the levitating state is heated and melted by ray or heat irradiation or by a resistance heater. Thereafter, the heating is stopped, and the substance 6 is cooled as such in the levitating state. Since the magnetic force realizes the microgravity field where the substance 6 is melted and cooled in the levitating state, the substance 6 is formed to an ideally spherical shape with an extremely smooth surface.Type: GrantFiled: March 14, 2001Date of Patent: September 17, 2002Assignees: Japan Science and Technology Corporation, Japan as Represented by Director-General of National Institute of Advanced Industrial Science and Technology, Ministry of Economy, Trade and IndustryInventors: Mitsuhiro Motokawa, Kazuo Watanabe, Satoshi Awaji, Iwao Mogi, Naoyuki Kitamura, Masaki Makihara
