摘要： A printhead includes a silicon substrate, a first barrier layer, a second barrier layer, and a nozzle plate. The silicon substrate has a plurality of thermal elements and a main ink supply channel, each of the thermal elements being in a firing chamber of the first barrier layer and in fluid communications with the main ink supply channel through ink channels. The top of each ink firing elements is aligned with a nozzle on the nozzle plate. To satisfy the need for high-frequency ink ejection, the second barrier layer is utilized to provide an auxiliary ink supply channel for increasing the ink supply speed. The ink channel between the main ink supply and the ink channel inlet is enlarged in the vertical direction so as to lower the pressure and thus increase the ink supply speed.

摘要： A method of manufacturing a piezoelectric ink-jet print-head uses a metallic layer and a thick film layer with a slot hole therein instead of a ceramic vibration plate and an ink layer. The piezoelectric layer and the upper electrode layer are formed inside the ink cavity so that overall thickness of the print head is reduced. To form the ink-jet print head, a metallic layer and a lower electrode layer are sequentially formed over a substrate. A patterned piezoelectric layer and an upper electrode layer are sequentially formed over the lower electrode layer. A patterned thick film layer with a slot hole therein is formed over the metallic layer. The thick film layer and the metallic layer together form a cavity that encloses the piezoelectric layer and the upper electrode layer. A nozzle plate having a nozzle thereon is attached to the thick film layer. The nozzle plate, the thick film layer and the metallic layer together form an ink cavity. The hole in the nozzle is continuous with the ink cavity.

摘要： A method of forming a nozzle plate of an inkjet print head. A silicon chip is provided with an activated device and a first film is formed on the silicon chip, with a first opening corresponding to the activated device. Then, a second film is formed on the first film. Next, a photoresist layer is formed on the second film, such that the photoresist layer has a second opening corresponding to the first opening. Next, the second film under the second opening of the photoresist layer is etched to form a via in the second film passing through the first opening.

摘要： An ink-jet cartridge for an ink-jet pen is disclosed. The cartridge includes a back pressure chamber in which the level of ink will be self-adjusted to provide ink for ejection and prevent ink from leakage. The ink-jet cartridge includes an ink reservoir for storing ink, a back pressure chamber, a print ink chamber and a print head. The back pressure chamber has one end fluid-communicated with the ink in the ink reservoir, and the other end fluid-communicated with the print ink chamber via an overflow vent which is at a position higher than the ink level of the ink reservoir. A suitable back pressure is applied to the back pressure chamber and the print ink chamber so that, when printing, the increased back pressure in the print ink chamber sucks ink from the ink reservoir through the overflow vent into the print ink chamber; while, when not printing, the extra height of the ink in the back pressure chamber relative to the ink level of the reservoir balances the back pressure at the back pressure chamber and the print ink chamber to prevent ink leakage from the print head. Therefore, it doesn't need a valve or a movable element to accomplish the ink supply and leakage prevention.

摘要翻译： 公开了一种用于喷墨笔的喷墨墨盒。 墨盒包括背压室，其中油墨的水平将被自调整以提供用于喷射的墨水并防止墨水泄漏。 喷墨墨盒包括用于存储墨水的墨水储存器，背压室，印刷墨水室和打印头。 背压室具有与油墨容器中的油墨流体连通的一端，另一端通过位于比油墨储存器的油墨高度高的位置的溢流口与打印油墨室流体连通。 向背压室和印刷油墨室施加合适的背压，使得当打印时，印刷油墨室中的增加的背压通过溢流口将油墨从油墨储存器吸入打印油墨室; 而当不打印时，相对于储存器的墨水水平，背压室中的墨水的额外高度平衡背压室和印刷墨水室上的背压，以防止油墨从打印头泄漏。 因此，不需要阀或可动元件来实现供墨和防漏。
