摘要： The ink cartridge of the present invention uses a directional fibrous collection enclosed within a bushing to temporally retain the ink therein, wherein at least one controlled capillary portion is provided. The controlled capillary portion can be formed by the bushing or by a predetermined shape located in the cartridge. The capillary forces of the controlled capillary portion are stronger than the one of other portion of the directional fibrous collection. The flow rate of the ink can be precisely controlled by the directional fibrous collection, and the controlled capillary portion can efficiently drain out the ink to the printhead and there is no bubble left therein.

摘要： A pressure control device for regulating the ink pressure of a multi-reservoir ink cartridge. The pressure regulator employs an external spring or springs plate assembly mounted between two neighboring ink reservoirs. The external surfaces of the spring or assembly are attached to the respective side face of the reservoirs. Each ink reservoir has at least a side face formed from a flexible non-elastic material. When all of the ink reservoirs are full, the spring or assembly is in a relaxed state. By withdrawing a small quantity of ink from each ink reservoir, atmospheric pressure exerts forces on the ink reservoirs leading to a small contraction. The resulting distortion of the spring or assembly produces a force that resists further contraction of the reservoirs. Since the pressures inside the reservoirs are smaller than external atmospheric pressure, a back-pressure that prevents any leakage of ink from the reservoirs is created. In addition, a pressure plate can be added to the spring means to squeeze the ink out of the reservoir more evenly.
摘要翻译：一种用于调节多储存器墨盒的墨压力的压力控制装置。压力调节器采用安装在两个相邻墨水容器之间的外部弹簧或弹簧板组件。弹簧或组件的外表面附接到储存器的相应侧面。每个墨水容器至少具有由柔性非弹性材料形成的侧面。当所有储墨器都已满时，弹簧或组件处于松弛状态。通过从每个墨水容器中抽出少量的墨水，大气压力对墨水容器施加力，导致小的收缩。所产生的弹簧或组件的变形产生抵抗储层的进一步收缩的力。由于储存器内部的压力小于外部大气压，因此产生防止墨水从储存器泄漏的背压。此外，可以将压力板加入到弹簧装置中以更均匀地将油墨挤出储存器。

摘要： An inkjet printhead chip structure and a method of estimating the working life through the detection of any defect on the chip structure. The method includes laying a metallic layer such as a tantalum layer over the chip and then shaping the metallic layer into a protective layer circuit. A portion of the metal protective layer covers the heating elements embedded in the chip. In printing, the heating elements heat up the ink to produce jets of ink. However, a portion of the heat is transferred to the metal protective layer thereby raising its temperature. Heat on the metal protective layer combined with any strayed residual ink bubbles that impinge upon the surface of the metal protective layer causes the metal to age. Since resistance of the metal protective layer will increase proportionally to the amount of aging, a measurement of the resistance is capable of estimating how much longer a given chip is suitable for use. Furthermore, if this special circuit layout runs across each long side of an ink slot, any cracks along the direction of the ink slot are detectable during resistance measurement.
摘要翻译：喷墨打印头芯片结构和通过检测芯片结构上的任何缺陷来估计工作寿命的方法。该方法包括在芯片上铺设诸如钽层的金属层，然后将金属层成形为保护层电路。金属保护层的一部分覆盖嵌入芯片中的加热元件。在印刷中，加热元件加热油墨以产生喷墨。然而，一部分热被转移到金属保护层，从而提高其温度。金属保护层上的热量与撞击在金属保护层表面上的任何杂散的残余墨水泡结合使金属老化。由于金属保护层的电阻与老化量成比例地增加，所以电阻的测量能够估计给定芯片适合使用多长时间。此外，如果这种特殊电路布局贯穿于墨槽的每个长边，则在电阻测量期间可以检测沿墨槽方向的任何裂纹。

摘要： A driver transistor structure of an inkjet print head chip and the method for making the same. Having several body contacts distributed all over the source of an active region of a large area MOSFET (Metal Oxide Semiconductor Field Effect Transistor), an equivalent RB from the MOSFET channel to the body contact is greatly diminished as the distance between them is reduced, thereby preventing the occurrence of a secondary breakdown. Since the body contact is installed inside the active region without defining in advance a body contact region and making the body contact in the field oxide layer outside the active region, about 20% of the driver transistor structure can be saved to lower the average manufacturing cost of each chip.

摘要： A common print head module that can accommodate either a single-color or multi-color inkjet print head comprises an ink cartridge having an ink output, and an inkjet chip arranged over the ink output. The ink cartridge internally includes ink channels that terminate through a surface of the ink output, wherein two adjacent ink channels are spaced apart by a channel wall. The channel wall has a top surface lower than the surface of the ink output where the ink channels terminate. The ink channels communicate with ink slots of the inkjet chip. When accommodating a single-color print head, the ink flows out through the ink channels over the channel wall. When accommodating a multi-color print head, the ink slots of the inkjet chip have slot walls that are sealed with the channel walls such that inks of different colors can be separately ejected through the ink slots.

摘要： ZSM-5 crystallites are produced with very low levels of blocking tetrapropyl ammonium ions (Q). The reaction mixture contains sources of silica, soda, alumina and trace amounts of Q ions as nucleation agents. Because the crystallites as synthesized from the aqueous medium exhibit only a very small fraction of blocking cations, there is always a diffusion path for the hydrated sodium ions to be exchanged without the need of prior removal of the blocking cations by calcination or otherwise. The small size crystallites can be exchanged, blended with other materials, and formed into catalyst particles. The silica to alumina ratio can be varied and when no aluminum is added, silicalite may be formed. The systhesis can be done in 24 hours or less.
