    摘要： Each of common electrode teeth 76-1, 76-2 and 76-3, and each of individual electrode teeth 77-1 and 77-2 are alternately arranged in the X1-X2 direction at predetermined intervals g. When a positive voltage is applied to the individual electrode teeth 77-1 and 77-2, an electric field 83-1 indicated by a line of electric force 82-1 is produced in a piezoelectric plate member 65 between the individual electrode tooth 77-1 and the common electrode tooth 76-1 and an electric field 83-2 indicated by a line of electric force 82-2 is produced between the individual electrode tooth 77-1 and the common electrode tooth 76-2. Likewise, an electric field 83-3 indicated by a line of electric force 82-3 is produced between the individual electrode tooth 77-2 and the common electrode tooth 76-2 and an electric field 83-4 indicated by a line of electric force 82-4 is produced between the individual electrode tooth 77-2 and the common electrode tooth 76-3. Depending on the piezoelectric constant d33, X1-X2 direction components of the electric fields causes the piezoelectric plate member 65 to expand efficiently, as indicated by numerals 83-1-83-4. An expanding action of the piezoelectric plate member 65 causes a bimorph element 69 to bulge into a dome configuration.

    摘要： A printing head including a plurality of impact printing wires constituting a dot matrix and a plurality of actuators for respectively and selectively driving the printing wires. Each actuator is constituted of a movable member to which the printing wire corresponding thereto is connected, a base member, a piezoelectric device mounted on the base member, and first and second leaf springs. The first leaf spring is connected between the movable member and the piezoelectric device, and the second leaf spring is connected between the movable member and the base member in parallel relationship to the first leaf spring. Each of the first and second leaf springs has a shape such that it is narrowest at the central portion thereof and is gradually widened toward the opposite ends thereof. Owing to this shape, a stress generating at the opposite ends of each leaf spring can be reduced to thereby prevent breakage of each leaf spring.

    摘要： An apparatus for driving a printing head of a wire-dot printer, the head including a plurality of electroexpansive elements for driving respective printing wires cooperatively constituting a wire-dot matrix and in accordance with print pattern data designating the existence, or non-existence, of a dot to be printed by the respective, plural dot-impact printing wires in each of a succession of print cycles. Each electroexpansive element, selectively, is expanded and shrunk by an electrical charge/discharge, thereby to move the respective printing wire and perform a dot printing operation. The time intervals T1 and T2 respectively for the charge and discharge in each of a succession of printing cycles are: in the case of continuous dots, T1=A, T2=B' for the first dot, T1=A', T2=B' for successive dots intermediate the first and the last dots, and T1=A', T2=B for the last dot of the continuous dots, and in the case of a single dot, T1=A, T2=B, wherein A>A', and B>B'.

    摘要： A printing head includes a plurality of printing members constituting a dot matrix, and a plurality of actuators for driving the printing members, respectively. Each of the actuators comprises a resiliently movable member having one end to which the printing member is connected and the other end fixedly secured to a head base. An electro-distortion device can be used for exerting a displacement of the movable member, to enlarge the displacement at the one end and drive a printing member. The movable member is shaped substantially, between an actuating position and a fixing point, as one or more triangles, in a face of the flat material, in such a manner that the base and peak of the triangles are located substantially at the fixing and actuating positions, respectively.

    摘要： A plurality of multicolored transparencies or pictures having different parallactic views of a scene are aligned with each other and illuminated by red, green, and blue coherent beams. The resulting images are focused on a holographic recording medium through an aperture elongated along the direction of the alignment of the pictures. A hologram is recorded by red, green, and blue coherent reference beams directed at the recording medium. The images are reconstructed with a white reconstructing beam or a reconstructing beam composed of quasi-monochromatic colors and observed through an aperture corresponding to the first aperture and arranged in the same position. The hologram has recorded thereon a focused image hologram of the pictures and a Fresnel hologram of the aperture. The reconstructed image may be expanded by a screen which is directive in one direction, i.e. retroreflective horizontally, and dispersive in another direction, i.e. vertically dispersive.
