摘要： A thermally-driven ink-jet printhead includes a substrate having an ink chamber to be filled with ink to be ejected, a manifold for supplying ink, and an ink channel for providing flow communication therebetween. First and second sidewalls are formed to a predetermined depth from an upper surface of the substrate and define the ink chamber to have a substantially rectangular shape. A nozzle plate including a plurality of material layers is formed on the substrate. A nozzle passes through the nozzle plate and is in flow communication with the ink chamber. A heater is disposed between the nozzle and one of the first sidewalls above the ink chamber. A conductor is electrically connected to the heater. The conductor and the heater are disposed within the nozzle plate. A shifting feature moves cavitation points beyond an outer edge of the heater.

摘要： A power supply apparatus having a fuel cell and a rechargeable battery and a method of controlling power supplied by the apparatus to a load. A DC-DC converter is selectively supplied with power from the fuel cell or from the fuel cell and the battery based on an amount of a load current. The battery is recharged from an output of the DC-DC converter to increase an overall efficiency of the DC-DC converter and the fuel cell when the load current is low. The battery supplements power input to the DC-DC converter when the load current is high or when an output voltage of the fuel cell becomes unstable.
