    • A method of forming a fluid chamber and a source of fluid impedance includes providing a substrate having a surface; depositing a first material layer on the surface of the substrate, the first material layer being differentially etchable with respect to the substrate; removing a portion of the first material layer thereby forming a patterned first material layer and defining the fluid chamber boundary location; depositing a sacrificial material layer over the patterned first layer; removing a portion of the sacrificial material layer thereby forming a patterned sacrificial material layer and further defining the fluid chamber boundary location; depositing at least one additional material layer over the patterned sacrificial material layer; forming a hole extending from the at least one additional material layer to the sacrificial material layer, the hole being positioned within the fluid chamber boundary location; removing the sacrificial material layer in the fluid chamber boundary location by introducing an etchant through the hole; forming the fluid chamber by introducing an etchant through the hole; and forming a source of fluid impedance.

    • An asymmetric heat-type inkjet printer includes an inkjet printhead having at least one nozzle for continuously ejecting a stream of ink that forms a train of ink droplets, a heater disposed adjacent to the nozzle for selectively thermally deflecting the droplet forming stream of ink either toward a printing medium, or an ink gutter that captures and recirculates the ink. To increase the angle of deflection that the intermittently operated heater imposes on the droplet-forming stream of ink, a steering fluid assembly is provided in communication with the inkjet nozzle for co-extruding a thin film of fluid around the ink which has a higher volatility and a lower thermal diffusivity than the liquid forming the ink. When the ink is water based, the steering fluid may be, for example, polyethylene oxide based surfactant, or isopropanol. The invention allows water-based ink droplets in such printers to be deflected at greater angles in response to heat pulses generated by the heater, thereby enhancing printing accuracy and speed.
    • 不对称热式喷墨打印机包括具有至少一个喷嘴的喷墨打印头,用于连续喷射形成墨滴系列的墨水流;邻近喷嘴设置的加热器,用于选择性地将墨滴形成墨水热偏转到 打印介质或捕获并再循环墨水的墨槽。 为了增加间歇操作的加热器对墨滴形成流的偏转角度,提供了一种与喷墨喷嘴连通的转向流体组件,用于将具有较高挥发性的油墨周围的薄膜流体共挤出 并且比形成油墨的液体具有更低的热扩散率。 当油墨是水基时,转向流体可以是例如聚环氧乙烷基表面活性剂或异丙醇。 本发明允许这种打印机中的水基墨滴响应于加热器产生的加热脉冲以更大的角度偏转,从而提高打印精度和速度。

    • A continuous inkjet printer in which a continuous ink stream is deflected at the printhead nozzle bore without the need for charged deflection plates or tunnels. The printhead includes a primary ink delivery channel which delivers a primary flow of pressurized ink through an ink staging chamber to the nozzle bore to create an undeflected ink stream from the printhead. A secondary ink delivery channel adjacent to the primary channel is controlled by a thermally actuated valve to selectively create a lateral flow of pressurized ink into the primary flow thereby causing the emitted ink stream to deflect in a direction opposite to the direction from which the secondary ink stream impinges the primary ink stream in the ink staging chamber. A method of fabricating the printhead includes layering of the thermally actuated valve over the secondary ink delivery channel formed in a silicon substrate and creating the ink staging chamber over the delivery channels with sacrificial material which is later removed through the nozzle bore etched into the chamber wall formed over the sacrificial material.
