摘要： Devices used to degas and eject fluid drops are disclosed. Devices include a flow path that includes a pumping chamber in which fluid is pressurized for ejection of a fluid drop, and a semi-permeable membrane including an inorganic material having an outer surface positioned in fluid contact with the flow path. The membrane allows gases to pass therethrough, while preventing liquids from passing therethrough.

摘要： A printhead module includes a printhead body, a nozzle plate and one or more piezoelectric actuators. The printhead body includes one or more pumping chambers, where each pumping chamber includes a receiving end to receive a printing liquid from a printing liquid supply and an ejecting end for ejecting the printing liquid from the pumping chamber. The nozzle plate includes one or more nozzles formed through the nozzle plate. Each nozzle can be in fluid communication with a pumping chamber and receive printing liquid from the ejecting end for ejection from the nozzle. The one or more piezoelectric actuators are connected to the nozzle plate. A piezoelectric actuator is positioned over each pumping chamber and includes a piezoelectric material configured to deflect and pressurize the pumping chamber, so as to eject printing liquid from a corresponding nozzle in fluid communication with the ejecting end of the pumping chamber.

摘要： The present invention comprises an inkjet print head structure wherein the placement of the transducer electrodes in combination with the particular poling direction of the print head transducer material provides for an efficient combination of shear and normal mode actuation of the print head. The preferred print head structure may be formed as a densely packed linear series of substantially parallel ink channels interspaced between and adjacent to a series of substantially parallel air channels. Further, the present invention provides for a print head structure wherein structures in contact with ink are maintained at ground potential. The present invention provides for a method to manufacture a print head having an array of densely packed ink channels having the characteristics of reduced mechanical crosstalk.

摘要： An improved electrographic writing head employs interleaved arrays of writing nibs and small geometry, high impedance, thick film resistors and semiconductor driver circuits fabricated on a glass epoxy substrate. The writing head achieves significant savings in manufacturing costs by using low cost printed circuit and thick film technology. Power consumption may be reduced by more than half over prior art devices due to the high impedance of each thick film pull up resistor coupled with a associated writing nib. A ground plane is disposed internally of the substrate and between adjacent arrays of writing nibs. The ground plane prevents electrical interaction between the substrates and prevents the formation of parasitic nib-to-nib capacitance by shunting parasitic capacitance currents to ground. The ground plane thus reduces the possibility of flaring and substantially eliminates inadvertent writing by adjacent nibs.
摘要翻译：改进的电子写入头使用在玻璃环氧树脂基板上制造的写入笔尖和小几何形状，高阻抗，厚膜电阻器和半导体驱动器电路的交错阵列。写头通过使用低成本印刷电路和厚膜技术实现了制造成本的显着节省。由于每个厚膜上拉电阻与相关联的写入笔尖耦合的高阻抗，因此功耗可以比现有技术的器件减少一半以上。接地平面设置在衬底内部和相邻的写笔尖之间。接地平面可防止衬底之间的电气相互作用，并通过将寄生电容电流分流到地来防止形成寄生的笔尖至笔尖电容。因此，接地平面因此减少了扩张的可能性，并且基本上消除了相邻笔尖的无意写入。
