  • Publication number: 20060000772
    Abstract: A channel (103) is formed in a substrate (101), and a portion of the channel (103) is provided with a separating portion (107). A number of pillars are formed in the separating portion (107), and an adsorptive substance layer having an adsorptive substance, which exhibits a specific interaction for a specific substance, immobilized on the surface thereof, is formed. Once a sample is introduced into the channel (103), the specific substance is adsorbed on the adsorptive substance layer to be separated from other components. After washing the inside of the channel (103) with a buffer solution, the specific substance is desorbed from the adsorptive substance layer by flowing a eluting solution through the channel (103) and the specific substance is recovered.

  • Patent number: 6970050
    Abstract: An oscillator includes a transistor, a first bias resistor connected between the base of the transistor and a power input terminal, and a second bias resistor connected between the base of the transistor and a control-voltage input terminal. When the control-voltage input terminal is grounded, the bias voltage at the base of the transistor is below a predetermined threshold, thus causing the oscillator to stop oscillation. When the control-voltage input terminal is open, the bias voltage at the base of the transistor is above the threshold, thus causing the oscillator to start oscillation.

  • Publication number: 20050239210
    Abstract: An analytical chip for use in the analysis of a protein, a nucleic acid or the like, includes a substrate fitted with a channel wherein a sample is introduced. In the channel, there is provided a reagent layer containing a reagent, the reagent capable of detecting the presence of specified component and capable of indicating the specified component presence through color formation or other means. A sample is introduced in the channel through a sample introduction port and is developed over the reagent layer. The state of any reaction accompanying the reagent development is magnified with a microlens and can be easily observed. By virtue of this analytical chip, not only is it unnecessary to install special external equipment for detection and analysis but also, after specimen application, analytical result can be immediately found at the very site by visual inspection.

  • Patent number: 6881315
    Abstract: A fractionating apparatus is used for fractionating sample into micro-structures different in size, and includes a fractionating unit formed with a fractionating passage; the fractionating passage is defined in a groove formed in a substrate of the fractionating unit, and pillar patches are formed in the groove at intervals wider than the gap among the pillar patches; while the sample is migrated through the fractionating passage, small-sized DNA molecules are trapped in the pillar patches, and large-sized DNA molecules are smoothly migrated through the wide intervals; this results in that the large-sized DNA molecules reaches the end of the fractionating passage faster than the small-sized DNA molecules without clogging.

  • Patent number: 6828747
    Abstract: The stop positions of start and end points for a slider are set by positionally adjusting a stopper and/or a stopper. The distance that the slider has traveled is learned according to a command from a control console in response to a manipulation of a learning manipulation element, and at least one of a speed and an acceleration is set by a speed regulator and an acceleration regulator. The control console outputs a drive signal to a motor based on at least one of the set speed in constant-speed movement of the slider and the set acceleration of accelerated movement of the slider and the learned distance that the slider has traveled, thereby moving the slider. For moving the slider to the start point or the end point, the control console controls the slider to move at a speed lower than the speed in constant-speed movement, and positions the slider at the start point or the end point.

  • Publication number: 20040196991
    Abstract: The present invention relates to a sound image localizing apparatus for generating a sound image localized in an arbitrarily set three-dimensional direction. The sound image direction setting unit (111) is operable to set a three-dimensional direction to which the sound image is to be localized in accordance with a listener's instruction; the angle conversion unit (112) is operable to convert the direction into a lateral angle (&agr;) and a rising angle (&bgr;), each of which serves as a cue for the listener to perceive the direction. The convolution operation unit 116 is operable to obtain lateral angle control information corresponding to the lateral angle (&agr;) from the lateral angle control information storage unit (113), a listener's front direction head-related impulse response from the front direction head-related impulse response storage unit (115), and rising angle difference information corresponding to the rising angle (&bgr;) from the rising angle difference information storage unit (114).
