<p><P>PROBLEM TO BE SOLVED: To provide a layered nozzle structure capable of carrying out micro-extrusion. <P>SOLUTION: The layered nozzle structure including an upper nozzle plate that defines a first inlet port, and a nozzle outlet plate that defines a long and narrow nozzle channel extending in a first predetermined flow direction up to a specified opening passing through a second front edge, with the upper nozzle plate attached onto the nozzle outlet plate to form an extrusion nozzle, a part of the upper nozzle plate forming an upper wall of the extrusion nozzle, a counter edge of the long and narrow channel forming a side wall of the extrusion nozzle, the opening formed in the second front edge defining an outlet orifice of the extrusion nozzle, the first inlet port aligned with the closed end of the long and narrow channel, whereby the extrusion material extruded through the first inlet port flows in the first flow direction along the extrusion nozzle and flows out of the outlet orifice to form the bead, also includes a means of deflecting the bead toward the target base. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
