  • Publication number: 20140300339
    Abstract: The present invention provides technology that uses current measurements to identify nucleotides and determine a nucleotide sequence in polynucleotides. The present invention calculates a modal value of a tunnel current that arises when a nucleotide or polynucleotide for analysis passes through between electrodes, and then employs the calculated modal value. The present invention accordingly enables direct rapid implementation to identify nucleotides and to determine a nucleotide sequence in a polynucleotide without marking.

  • Publication number: 20140183040
    Abstract: The present invention provides a method and apparatus for controlling the moving speed of a substance, both of which can adjust the moving speed of a substance to a desired speed. The control method and control apparatus cause a substance to pass through an internal space, in which an electro-osmotic flow is generated, of a surround electrode formed so as to surround part of the moving path of the substance, whereby the control method and control apparatus change the moving speed of the substance.

  • Patent number: 8044596
    Abstract: Electron-emissive drive units of electron-emissive elements capable of being arranged with a smaller pitch. FET and emitter array units exist in matrix element areas partitioned by a control wiring and data wiring. An exemplary unit is composed of four emitter arrays. The control wiring and data wiring are driven by first and second drive circuits, respectively. Corresponding arrays between units are connected by selection wiring and driven by a third drive circuit. The third drive circuit drives each unit of data wiring every time the drive circuit sequentially drives the four units of control wiring, and the emitter array drive circuit drives each emitter array selection wiring every time the drive circuit sequentially drives the three units of data wiring. Electrons can be emitted in units of arrays smaller than the unit.
