Abstract: 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.

Abstract: The ink cartridge is provided with a pressure controller to regulate the inner pressure therein by atmospheric pressure while the ink stored in the ink cartridge is gradually drained off. The ink is stored in a container with negative pressure therein, and at least one through hole formed on the container is used to connect to the atmosphere, and at least one recess is formed on the inner wall of the through hole. The pressure controller has a plug movably disposed on the through hole and the recesses. The recesses are used as a channel to allow the entrance of the atmospheric air, and the plug can be automatically moved so as to enlarge the clearance between the plug and the through hole while the ink stored in the ink cartridge is gradually drained off. The inputted air can effectively reduce the negative pressure in the container, and therefore the printing process of the ink cartridge can be proceeding steadily.

Abstract: 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.

Abstract translation: 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。
