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： An ink print head has an ink container for storing fluid, a chip installed at a bottom of the ink container having a central slot for passing fluid, and a dry film formed on the chip having a plurality of ink chambers. The ink print head also has a nozzle plate formed below the dry film, a middle portion of the nozzle plate protruding above the nozzle plate so as to form a central refill chamber, a plurality of nozzles corresponding to the ink chambers of the dry film, and a plurality of heaters set on the chip for heating fluid inside the ink chambers so that the fluid can be ejected from the nozzles of the nozzle plate. The fluid inside the ink container will flow through the central slot into the central refill chamber and then into the ink chambers.

摘要： 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.

摘要： 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.
