摘要： A bubble-jet type ink-jet printhead and manufacturing method thereof including a substrate integrally having an ink supply manifold, an ink chamber, and an ink channel; a nozzle plate having a nozzle on the substrate; a heater centered around the nozzle and an electrode for applying current to the heater on the nozzle plate; and an adiabatic layer on the heater for preventing heat generated by the heater from being conducted upward from the heater. Alternatively, a bubble-jet type ink-jet printhead may be formed on a silicon-on-insulator (SOI) wafer having a first substrate, an oxide layer, and a second substrate stacked thereon and include an adiabatic barrier on the second substrate. In the bubble-jet type ink-jet printhead and manufacturing method thereof, the adiabatic layer or the adiabatic barrier is provided to transmit most of the heat generated by the heater to ink under the heater, thereby increasing energy efficiency.

摘要： A microgyroscope with two resonant plates is provided. The microgyroscope includes a substrate; first and second frames provided on the substrate to have a predetermined height, the first and second frames facing each other; a plurality of anchors supporting the first and second frames with respect to the substrate; first and second resonant plates provided between the first and second frames to be separated from each other by a predetermined distance; and a matching link unit connected to the first and second resonant plates so that it links the motion of one resonant plate to the motion of the other resonant plate such that the matching link unit is moved by the motion of one resonant plate in a first direction and then moves the other resonant plate in a second direction opposite to the first direction. In the microgyroscope, the difference between the resonance frequencies of the two resonant plates is removed by a self resonant matching structure implemented by the matching link, so that the range of an allowable process error is large, and the microgyroscope can be easily manufactured. Additionally, the reliability and the linearity of a resonance structure are improved. Since the driving beam and the sensing beam are separately designed, mode coupling can be prevented, thereby increasing the sensing sensibility.

摘要： An electrostatic driving apparatus for a microactuator is provided, in which a parasitic capacitance is offset to improve the performance thereof. According to the complementary electrostatic driving apparatus for the microactuator, in order to prevent an excitation signal from being mixed with a sensing signal via the parasitic path formed of parasitic capacitance according to the structure of the microactuator and vibration characteristics thereof, which cause noise, signals having opposite polarities are applied to activating vibration plates using an inverter such that the activating vibration signals of each plate, which cause noise, are offset, thereby markedly improving the signal-to-noise ratio. Also, the vibration displacement can be easily detected by a circuit which is not integrated with an actuator. In addition, a sensing unit is simplified, reducing the initial costs. Further, when the excitation signals are applied at the both sides of the vibration direction of the suspended vibration plate, only the AC component, i.e., the .omega. component, of the electrostatic force acts, so that the resonant characteristics can be improved without an offset of the displacement.
