摘要： An ink-jet head includes pressure chambers arranged in a row in a row-direction, and a manifold flow passage communicated with the pressure chambers and extending in the row-direction. An ink inflow port is formed at one end of the manifold flow passage. The manifold flow passage has a main portion, a connecting portion, and an extended portion which are arranged in this order from a side close to the ink inflow port. The manifold flow passage is communicated with the pressure chambers at the main portion. The main portion has a constant cross-sectional area greater than that of the connecting portion. A cross-sectional area of the extended portion is greater than that of the connecting portion. The pressure wave, generated in the pressure chamber and propagated to the manifold flow passage, can be efficiently attenuated by the manifold flow passage constructed as described above.

摘要： A method of ejecting at least one droplet of an ink through a nozzle by applying a drive pulse signal having pulses to an actuator which changes a capacity of an ink chamber, for forming a dot corresponding to one picture element with a result of ejection of the droplet, the dot to be formed being selected from among a medium-volume dot constituted by the ink of a predetermined amount, a small-volume dot constituted by the ink whose amount is smaller than the predetermined amount, and a large-volume dot constituted by the ink whose amount is larger than the predetermined amount. In the method, where the small-volume dot is formed, the droplet is ejected by a first drive pulse signal as the drive pulse signal set for the small-volume dot to eject the droplet at a predetermined ejecting speed. Further, where the medium-volume or large-volume dot is formed, the at least one droplet is ejected by a second drive pulse signal as the drive pulse signal which is set for the medium-volume or large-volume dot, which has the same voltage as the first drive pulse signal, and which has a plurality of pulses. The second drive pulse signal is determined such that a pulse width of each pulse and a time interval between each pulse are equal to respective prescribed values for making an ejecting speed of the droplet for forming the medium-volume or large-volume dot equal to the predetermined ejecting speed of the at least one droplet for forming the small-volume dot.

摘要： When power failure of a commercial power source is detected, an inverter interrupts power supply to a power line extending between the commercial power source and a load via a circuit breaker. Then the control mode of a load DC—DC converter is changed to a constant voltage control to maintain stable operation of a fuel cell. This allows the accessory DC—DC converter to supply power to accessories used for operating the fuel cell power generation system. Also, the quantity of city gas to be supplied to a reformer is changed to a quantity necessary for the fuel cell to generate power for driving the accessories. This makes it possible to avoid excessive production of hydrogen, thus improving energy efficiency of the fuel cell power generation system.
