摘要： The conventional micropump and the conventional micromixer have the following problems. In a mechanical or hydrodynamic method, the structure of the inside of a flow path is complex so as to easily cause clogging, and manufacturing cost is high, and dead volume is large. Additionally, in an electrical method, the conventional micropump or the conventional micromixer was incapable of operating with a liquid having the concentration of a physiological saline that is important in the medical or biological field although the structure of the flow path is simple. These problems are solved by applying an AC voltage to a pair of electrodes in which an electrode-to-electrode gap between the pair of electrodes is vertically arranged and by generating the flow of a fluid in the direction opposite to gravity along the electrode-to-electrode gap. A micropump (43, 44) can be realized especially by forming a micro-sized flow path (11) in the vertical direction along the electrode-to-electrode gap, and a micromixer (41) can be realized by forming a micro-sized flow path (11) in the horizontal direction to cross at right angle to the electrode-to-electrode gap.

摘要： Conventionally, it has been difficult to effectively and promptly stir and mix fluids together by use of a microfluidic device having a simple flow path structure. Additionally, there has been no means for keeping a particulate sample floating in a fluid in a flow path for a long time without precipitating the particulate sample. Additionally, there has been no method for measuring the true size of a flowing and floating particulate sample by use of a microscope. The present invention solves these problems by using a microfluidic device in which an electrode pair having a wide electrode-to-electrode gap is formed in a flow path or in a chamber, and by applying an AC voltage to this electrode pair, and by generating an eddy by which a fluid is swirled in a torus manner. The accurate size of the particulate sample that crosses the in-focus plane can be measured especially by setting an in-focus plane (53) of an objective lens (52) of a microscope at a position through which a swirling flow (41) vertically passes.

摘要： An auxiliary substrate is provided so as to face a main substrate to which ink is supplied and the pattern of a voltage applied to an auxiliary electrode array formed on the auxiliary substrate is controlled. In a printing operation, the coloring material components are sent to the vicinity of an ink droplet emitting outlet and the coloring material components in the ink where the coloring material is dispersed in solvent are concentrated. Then, they are emitted from the ink droplet emitting outlet in the form of ink droplets and are forced to fly at a printing medium, thereby printing on the medium. In a non-printing operation, the auxiliary electrode array is controlled so that the coloring material components may be kept away from the ink droplet emitting outlet and the concentration of the coloring material components in the ink near the ink droplet emitting outlet is made lower than in a printing operation.
