摘要： An ink-jet recording device (1) comprises a first wall member or partition (24a) adjacent to an ink material (38a) and a second wall member or partition (24b) adjacent to an ink material (38b). An elasticity of the first wall member (24a) is different from that of the second wall member (24b). Arranged adjacent to the first and second wall members (24a, 24b) are first and second piezoelectric members (34), respectively. Once the piezoelectric members (34) are biased, they deform to force the adjacent ink materials through the wall members (24a,24b), ejecting ink droplets of different sizes. This ensures the ink-jet recording head to print a halftone image with a high gradation.

摘要： An ink jet head for a printer wherein an ink drop is ejected from a nozzle to fly and land on the recording paper to form an image. The ink jet head includes the nozzle for ejecting ink, an ink channel that communicates with the nozzle, a pair of oscillating plates that are opposing to each other on walls of the ink channel, a pair of electrodes disposed in contact with the oscillating plates, an ink chamber for holding the ink, and an inlet for supplying the ink from the ink chamber to the ink channel. A gap between the electrodes is filled with the ink having a relative dielectric constant higher than air. A voltage is applied between the electrodes.

摘要： A piezo-electric actuator is rigidly mounted for a portion of one surface and provided with opposing electrodes for application of a bias. Because the mounted portion is constrained from deformation, the piezo-electric actuator deforms in a bending manner upon application of a bias. The actuator is provided with a mirror surface for selective reflection of an incident light beam in accordance with a bending deformation of the actuator. The actuator can also modulate a light beam by selectably deflecting into the light path to thereby block the light beam.
