摘要： In an inkjet printhead, a substantially rectangular heater element has an aspect ratio greater than about 2.0. A bubble chamber surrounds a centrally disposed heater element with a plurality of walls. A nozzle plate has an orifice for projecting ink from the bubble chamber that axially extends through a thickness thereof. A center of the orifice originates a plumb line such that an offset distance exists from a center of the heater element in a range from about 6 to about 10 microns. An ink flow channel through one of the bubble chamber walls has a primary direction of ink flow substantially paralleling a length dimension of the heater element. The bubble chamber and ink flow channel may exist in the nozzle plate, a polymer barrier layer or a plurality of film layers that define a heater chip. More preferred aspect ratios include greater than about 2.5 and about 4.0.

摘要： An ink-jet printer cartridge having a center reservoir chamber and two side reservoir chambers for holding inks of three different colors is provided with ink flow pathways of special configuration for connecting the reservoir chambers to exit ports at the print element. The ink flow pathways are provided with ridges extending along substantially their entire lengths so that air bubbles cannot completely block ink flow through the pathways. The ink flow pathways are disposed such that they have a vertical component of direction over their entire length and the pathways connecting the side reservoir chambers to exit ports include duct portions disposed at compound angles relative to the axes of the cartridge so that air bubbles, because of their buoyancy, will naturally tend to drift upwardly through the inclined ducts toward the reservoir chambers during normal usage, or drift toward the exit openings when the cartridge is inverted for priming. The duct portions of the ink flow pathways are generally trapezoidal in cross-section, the side walls intersecting the top wall at acute angles so that air bubbles cannot completely block the duct portions. The duct portions have end surfaces for directing air bubbles toward the reservoir chambers during priming, the end surfaces being end faces of plugs.
摘要翻译：具有中央储存室和用于保持三种不同颜色的油墨的两个侧储存室的喷墨打印机墨盒设置有用于将储存室连接到打印元件处的出口的特殊结构的墨流路。油墨流动路径设置有沿着其整个长度延伸的脊，使得气泡不能完全阻止通过路径的油墨流动。油墨流动通道被设置成使得它们在其整个长度上具有方向的垂直分量，并且将侧面储存室连接到出口的路径包括相对于盒的轴线以复合角度设置的管道部分，使得气泡因为它们的浮力自然会倾向于在正常使用期间向上倾斜通过倾斜的管道朝储存室移动，或者当墨盒倒置以便起泡时向着出口开口漂移。油墨流动通道的管道部分的横截面通常为梯形，侧壁以锐角与顶壁相交，使得气泡不能完全阻挡管道部分。导管部分具有用于在起动期间将气泡引向储存室的端面，端面是插塞的端面。

摘要： A method of making flow feature structures for a micro-fluid ejection head. The method includes the steps of laser ablating a nozzle plate material to provide an elongate fluid chamber and fluid supply channel therein for connecting the fluid chamber with a fluid supply. The fluid chamber has a first length and a first width. An elongate nozzle hole is laser ablated in the nozzle plate material co-axial with the fluid chamber. The nozzle hole has entrance dimensions having a longitudinal axis dimension and a transverse axis dimension such that the longitudinal axis dimension is from about 1.1 to about 4.0 times the transverse axis dimension.

摘要： In an inkjet printhead, a substantially rectangular heater element has a length and width dimension defining an aspect ratio of more than about 2.0. A bubble chamber with a curved or convex wall portion partially surrounds the heater element. A radius of an arc defining the convex wall portion is greater than one-half the width dimension while less than one-half the length dimension and none of the convex wall portion overlies a periphery of the heater element. An ink ejection orifice exists through a thickness of a nozzle plate covering the bubble chamber and resides above the heater element. Additionally, the bubble chamber may have a rectangular wall portion connected to the convex wall portion and either portion may occupy a terminal end of the bubble chamber. Preferred length and width dimensions include 35 and 13 or 40 and 10 microns with a radius of about 16 microns.
