Abstract: A tool-hanging apparatus includes a hanger and a rotor. The hanger includes a ring, an inward flange formed on a rear internal section of the ring, and teeth formed on a front internal section of the ring. An internal diameter of the inward flange is smaller than a diameter of a circular defined by the teeth. The rotor includes elastic strips extending from a tube. Each of the elastic strips includes a groove between a ridge and a barb. One of the elastic strips includes a tooth extending from the ridge of the same. When the rotor is inserted in the ring, the grooves of the elastic strips receive the inward flange to keep the rotor in the ring and allow the rotor to rotate relative to the ring. The tooth is engageable with the teeth to keep the rotor at an angle relative to the ring elastically.

Abstract: A monolithic ink-jet print head and a method of fabricating the same are proposed, which not only can allow the nozzle device to be highly secured to the ink-jet print head, but also can allow the overall manufacturing process for the ink-jet print head to be more simplified and thus more cost-effective to implement as compared to the prior art. The monolithic ink-jet print head is constructed on a print-control chip formed with an array of transducers. A plurality of ink barrier layers are then formed from a first polymer over the print-control chip for separating the transducers from each other; and subsequently, a nozzle device is formed from a second polymer over the ink barrier layer. The second polymer is substantially equal or at least close in thermal expansion coefficient to the first polymer used to form the ink barrier layer. Therefore, the nozzle device would hardly break apart from the ink barrier layer after a long period of use that would easily occur in the prior art due to repeated unequal thermal expansions during operation. Moreover, the monolithic process to fabricate the ink-jet print head also allows the manufacture of the ink-jet print head to be easily carried out for mass production with reduced manufacturing cost simply through conventional semiconductor fabrication processes.

Abstract translation: 提出了一种单片喷墨打印头及其制造方法，其不仅可以使喷嘴装置高度固定在喷墨打印头上，而且可以允许喷墨打印头的整个制造过程 与现有技术相比，打印头更加简化，因此实现更具成本效益。 单片喷墨打印头构造在由换能器阵列形成的打印控制芯片上。 然后在印刷控制芯片上由第一聚合物形成多个油墨阻挡层，用于将换能器彼此分离; 随后，喷墨装置由墨阻挡层上的第二聚合物形成。 第二聚合物与用于形成油墨阻挡层的第一聚合物的热膨胀系数基本相等或至少接近。 因此，由于在操作期间重复的不平等的热膨胀，在现有技术中很容易发生长时间的使用后，喷嘴装置几乎不会从油墨阻挡层脱离。 此外，制造喷墨打印头的整体工艺还允许通过简单地通过常规的半导体制造工艺简单地制造喷墨打印头来简化地进行批量生产，同时降低制造成本。
