|Title||LIQUID JET DISCHARGE DEVICE AND LIQUID JET DISCHARGE METHOD|
|Abstract||This liquid jet discharge device is equipped with: a narrow tube that is cylindrical and open on both ends thereof, and has a dischargeable liquid positioned therein, the contact angle of which is less than 90° relative to at least the inner surface; a container having a transmission medium that is capable of transmitting pressure to the dischargeable liquid and provided on the floor-section side thereof, where the one end of the narrow tube is located; and an adjustment mechanism for performing a positional shift in the axial direction of the narrow tube of the fluid level of the dischargeable liquid in the narrow tube and the transmission-medium interface outside the narrow tube and inside the container; and a generation mechanism for causing the transmission medium to generate a pressure wave so as to discharge a liquid jet from the dischargeable liquid inside the narrow tube.|
|Outline of related art and contending technology||
The liquid jet is, the conventional ink jet printer (for example, 'series' digital printer technology' ink jet, Tokyo electrical University Press, (2008), Imaging Society of Japan, (ISBN978-4-501-62340-1 C3072) (hereinafter, 'the non-patent document 1' that) reference) and micro processing device such as a display used in various fields. Such a liquid jet injection most of the equipment, the diameter of the spray liquid jets in the same as or higher than the inner diameter of the emitting device. For example, a bubble jet or piezo ink jet type used in an ink jet printer (registered trademark) corresponds to the method, both the liquid injection hole (nozzle) is pushed out of the method. For this reason, the diameter of the emitted droplets, greater than or equal to the diameter of the injection hole.
On the other hand, the liquid surface in the concave shape of the injection tube, a large acceleration is applied in a short time, the inner diameter of the spray emitted from a size of about 1/5 of the liquid jet can be injected. Can be applied to such a fine liquid jets, or the problem of the inkjet printer or the extrusion method can be solved the problem of clogging.
In this way as a method of generating fine liquid jets, the filled liquid is irradiated with a laser tube may be a method (for example, 'Tagawa, Y., Oudalov, N., Visser, C. W., Peters, I. R., van der Meer, D., Sun, C., Prosperetti,A. and Lohse, D., Highly focused supersonic microjets, Physical Review X, Vol. 2, (2012), 031002.(hereinafter, ' the non-patent document 2' that) reference).
In addition, as a method of generating other, filled with a liquid free fall of the test tube, and a floor of an impulsive force by the collision is used (for example, 'Antkowiak, A., Bremond, N., Dizes,S. L and Villermaux, E., Short-term dynamics of a density interface following an impact, Journal of Fluid Mechanics, Vol. 577, (2007), pp. 241-250.(or less, ' Non-Patent Document 3 'that) and' the intermediate kiyama Laboratories, nearly noguchi doo, yoshiyuki tagawa 'liquid jet generated by an impulsive', equal to or less than, Vol.80,No.814,2014'(Japan Society of Mechanical Engineers Papers, ' Non-Patent Document 4' that) reference).
