Title:
非円形のノズル孔をもつ連続インクジェットシステム
Document Type and Number:
Japanese Patent JP4592178
Kind Code:
B2
Abstract:
A continuous ink jet printing system using asymmetrical heating of the fluid in which the nozzle bore (46, 76, 78) of the printhead preferably has a non-circular opening. The nozzle bore (46, 76, 78) has reflection symmetry about the long axis of its cross-section and may be, for example, elliptical or rectangular. In the preferred embodiment of the invention, the nozzle bore (46, 76, 78) has an aspect ratio greater than unity, wherein the aspect ratio is defined as the ratio of the long axis length to the short axis length. A heater (50, 50', 50") used to generate deflection of the fluid exiting the nozzle bore (46, 76, 78) generally conforms to the perimeter of the nozzle bore (46, 76, 78) such that the heated portion is along the long dimension of the nozzle bore (46, 76, 78).
