    摘要： A liquid-drop ejection device having a plurality of ejectors (7) each having a variable-capacity ink channel (4). The capacity of the ink channels (4) is variable to generate sufficient pressure to thereby eject ink in the ink channels from nozzles communicating with the ink channels (4) onto paper or the like. The ejection device further comprises a piezoelectric transducer having a plurality of walls (3) for separating the ink channels (4) from one another. The walls have drive electrodes (5) formed on upper or lower portions. The upper portions of the walls (4) are narrower in width than the lower portions. A method of forming the ejection device comprises a first step of forming grooves (4) including portions for receiving drive electrodes (5), a second step of forming the drive electrodes (5) in the grooves (4) and a third step of further forming the grooves (4) to provide additional portions having widths different from the portions of the grooves (4) formed in the first step.

    摘要： A data converting apparatus for converting outline data representative of an outline of a character, into dot data including dot-forming bits each indicative of the presence of an image dot to be formed at a position of a corresponding dot-forming picture element which lies within the outline of each stroke of the character, so as to satisfy a predetermined requirement, when the outline of the character is superimposed on a pixel screen wherein picture elements are defined by x-axis pixel lines and y-axis pixel lines perpendicular to the x-axis pixel lines. The apparatus includes a device for determining whether or not a difference between an outline width of each character stroke as defined by the outline data and a reproduction width of the as reproduced according to the dot data as normally prepared based on the outline data exceeds a reference value. The normally prepared dot data are changed so as to reduce the difference between the outline and reproduction widths, if the difference exceeds the reference value.

    摘要： An ink droplet jet device in which the volume of the ink channels is varied by deformation of the side walls due to piezoelectric thickness shear mode to thereby jet an ink droplet requires sufficient volume variation of the ink channels to function reliably. To satisfy this requirement, the material and thickness of an adhesive agent used to secure the piezoelectric plate to the cover plate is selected so that the value obtained by dividing Young's modulus of adhesive agent for adherence between the upper surface of the side wall of the piezoelectric plate and the cover plate by the thickness of the adhesive agent is above 5 X 10³ kg/mm³, preferably 5 X 10⁴ kg/mm³, and more preferably above 1.2 X 10⁵ kg/mm³. Further, the material and thickness of the adhesive agent is selected so that the value obtained by dividing Young's modulus of the adhesive agent for adherence between the end surface of the side wall and the nozzle plate by the thickness of the adhesive agent is below 1 X 10⁶ kg/mm³, preferably 5 X 10⁵ kg/mm³, and more preferably 3 X 10⁵ kg/mm³. By these settings, the jet velocity of the ink droplet is above a predetermined value, and stable ink droplet jetting can be performed.
