摘要： An ink-jet printhead and a manufacturing method thereof include a substrate on which a space portion is formed, a passage plate installed on the substrate in which an ink chamber is formed to store ink, a nozzle plate installed at a top surface of the passage plate in which a nozzle is formed to eject the ink, and a vibration plate disposed between the substrate and the passage plate to generate a pressure for ejecting the ink by changing a volume of the ink chamber. The vibration plate includes a base layer formed at a top surface of the substrate so as to cover at least a part of the space portion, a thin film shape memory alloy layer which contacts the ink contained in the ink chamber and varies according to a temperature variation, a heating element disposed between the base layer and the thin film shape memory alloy to generate heat, and an insulating layer disposed between the heating element and the thin film shape memory alloy layer and transfers the heat generated by the heating element to the thin film shape memory alloy layer. Due to a stable temperature coefficient of resistance (TCR) of the heating element, a height and a width of a voltage supplied to the heat element can be easily controlled, and thus power of the vibration plate can be precisely controlled, thereby having a predetermined image quality, and the heating element does not contact directly the ink, thereby realizing stability of the ink-jet printhead.

摘要： An ink cartridge for an ink jet printer is provided. The provided ink cartridge has an ink reservoir and a housing for covering the ink reservoir with a negative pressure maintenance unit therebetween, to maintain the inner pressure of the ink reservoir under a negative pressure. Since the negative pressure maintenance unit does not contact ink in the ink reservoir, the negative pressure maintenance unit does not corrode. In addition, the negative pressure maintenance unit is installed between the housing and the ink reservoir while occupying a small space, and thus improving the filling efficiency of ink in the ink reservoir.

摘要： A bubble-jet type ink-jet printhead has a structure in which a base plate, a barrier wall, and a nozzle plate are stacked. The base plate includes a substrate on which a recess is formed to a predetermined depth, an adiabatic layer formed on the substrate, a heater which is formed on the adiabatic layer and generates a thermal energy, and a passivation layer which is formed on the heater and passivates the heater. The barrier wall is stacked on the base plate, defines an ink chamber, which is disposed on the recess and has a recessed bottom surface, and defines an ink passage which communicates with the ink chamber. The nozzle plate is stacked on the barrier wall, has nozzles through which ink is ejected, and is formed at a location corresponding to a center of the ink chamber. Since a height of the barrier wall surrounding the ink chamber is reduced by the recess, delamination caused by ink soaked into the barrier wall can be prevented, and print performances such as a traveling property in a straight direction of ink droplets and ejection velocity of ink droplets, are improved.

摘要： Disclosed is a method for optimizing a driving input signal in an ink jet head using shape memory alloy. The method comprising the steps of: (a) determining a voltage inputted when a replacement generating time in a shape memory alloy layer disposed in the ink jet head is minimal, as a reference input voltage; (b) measuring a first time from a reference input voltage supply starting point to a displacement starting point of the shape memory alloy layer; (c) measuring a second time from after the first time measured in step (b) to a point when a displacement of the shape memory alloy layer is maximal; (d) determining a sum of the first and second times which are measured in steps (b) and (c), respectively, as a reference input voltage applying time; (e) calculating energy applied to the ink jet head, on the basis of the reference input voltage and the reference input voltage applying time which are determined in steps (a) and (d), respectively; and (f) determining a waveform of a driving voltage by measuring a firing velocity and a size of ink droplets while variously changing a voltage and a voltage applying time, such that energy less than the energy which is calculated in step (e) is obtained.
