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： The present invention is an ink pressure adjustment device of inkjet pen; the device is utilized to adjust negative pressure in an ink cartridge mainly through an expandable and shrinkable gasbag installed in the ink cartridge, and a tension valve attached on the surface of the gasbag. The tension valve can open or close automatically an air hole that communicates atmosphere and the inner part of ink cartridge via the gasbag according to the expansion and shrinkage of the gasbag, causing a part of atmosphere to enter the ink cartridge so as to adjust the negative pressure of the ink cartridge and not only can prevent ink from leaking but also prevent the negative pressure from being too large to fail the inkjet printing.

摘要： A magnetoelectric apparatus for measuring the droplet frequency response at a printhead by applying a method comprising a metallic detecting plate and a magnetic ring, and a method using the foregoing apparatus to determine the maximum droplet frequency response of the printhead. When an ink drop jetted from the nozzle makes contact with the detecting plate, which is perpendicular to the nozzle plate of the printhead, a current flows through the detecting plate immediately, and is detected as a portion of an expected signal. As soon as the ink drop leaves the nozzle completely, the foregoing current no longer exists. However, the magnetic ring generates an induced current that flows in the same direction as that of the foregoing current to complement the absence thereof, wherein the induced current is also detected as another portion of the expected signal. The expected signal is then processed by a signal-processing routine for determining the maximum droplet frequency response of the inkjet printhead.

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。
