<p><P>PROBLEM TO BE SOLVED: To obtain a conductive liquid delivering apparatus which can control an amount of delivering of a conductive liquid by delivering the conductive liquid utilizing a Lorentz force, and prevents clogging. <P>SOLUTION: In the conductive liquid delivering apparatus, one set of opposed electrodes and one set of opposed magnetic poles are arranged schematically orthogonally in the vicinity of a nozzle tip to which the conductive liquid is supplied. An electric current is flown to the conductive liquid by impressing an electric voltage to the electrodes. The conductive liquid is delivered by the generated Lorentz force. Thereafter, the Lorentz force in an opposite direction is acted, thereby preventing trailing delivering of the liquid and liquid sagging. Moreover, nozzle devices are set in two stages with a channel cross-sectional area being changed. The liquid is sent to a nozzle part of the second stage narrow in channel cross-sectional area at the tip only at the time of liquid delivery, and is delivered. The liquid is held at a position of the first stage wide in channel cross-sectional area at the other time than the above. The conductive liquid delivering apparatus is thus constituted to prevent clogging. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
