  • Patent number: 7198906
    Abstract: 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.

  • Patent number: 7081353
    Abstract: 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.

  • Patent number: 6559955
    Abstract: An apparatus for measuring rectilinear motion and rotation angle errors of a rectilinearly moving body having a horizontal, parallel two-surface mirror positioned in a horizontal plane and including two reflection mirrors whose reflection surfaces face each other and are spaced by a distance (2)d and a vertical, parallel two-surface mirror positioned in a vertical plane and including two reflection mirrors whose reflection surfaces face each other and are spaced by a distance (2)d, and also has a light source for generating a laser beam, semi-transparent mirrors for splitting the laser beam into two laser beams, optical path changing reflection mirrors for changing a direction of each laser beam, and position sensors for detecting positions of the laser beam reflected from the horizontal, parallel two-surface mirror and the vertical, parallel two-surface mirror, respectively fixed to positions outside of the rectilinearly moving body.

  • Patent number: 6559951
    Abstract: An optical measuring light path formed by a vacuum-side laser beam (Pa) as a reference standard and an optical measuring light path formed by a gas-side laser beam (Pb) as a dimension to be measured are coaxially located sandwiching a movable end (optical transparent body 12) of a vacuum container (11) in order to satisfy Abbe's principle requiring linear disposition of the reference standard and the dimension to be measured in measurement direction, thereby reducing measurement error in measuring air refractive index and improving measurement accuracy therefor.

  • Patent number: 6452140
    Abstract: 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.
