摘要： A method of flushing a nozzle of an inkjet recording head so as to recover an ink-ejection performance of the nozzle. The nozzle ejects, in a recording mode of the inkjet recording head, a plurality of droplets of an ink to record dot images, such that each of the droplets has an arbitrary one of a plurality of volumes. The flushing method includes causing the inkjet recording head to perform, for a first time, a plurality of continuous flushing actions in each of which the nozzle attempts to eject a droplet of the ink whose volume is larger than a smallest volume of the plurality of volumes, and causing the inkjet recording head to repeat, at least one more time, the plurality of continuous flushing actions while interposing a pause time between each pair of consecutive times out of the first time and said at least one more time.

摘要： A dielectric waveguide tube band-pass filter assuming lower characteristic change upon mounting, and having smaller dimensions and lower loss. Conductor layers (2a, 2c) are formed on the top and bottom surfaces of a dielectric substrate (1), wherein the top conductor layer 2a and the bottom conductor layer 2c are connected together through via-holes (3a). The via-holes (3a) are formed in at least two rows along the signal transfer direction. In the dielectric waveguide tube configured by the top and bottom conductor layers (2a, 2c) and the via-holes (3a), via-holes (3b) are arranged in the signal transfer direction at spacing equal to or below ½ of the in-tube wavelength to thereby configure resonators. The dielectric band-pass filter is configured by coupling adjacent resonators together through the via-holes (3b) configuring inductive windows. On the surface of the dielectric substrate (1), a co-planar line (4) including the conductor layer (2) as the ground and the conductor layer (2b) as a signal conductor is configured so as to overstride the inductive windows configured by the via-holes (3a).

摘要： An ink jet recorder includes an ink jet head having a nozzle, which can be capped with a cap and a suction pump for purging the nozzle through the cap. The recorder further includes a pressure control unit interposed between an ink supply and the head to control the pressure on the ink in the nozzle. At least just before purging finishes, the control unit applies positive pressure to the ink in the nozzle to prevent the air bubbles, the foreign substances and/or the like sucked into the cap by the pump from flowing back into the head. The control unit may include an ink tank and a height adjuster for adjusting the height of the tank relative to the front end of the nozzle.
