    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.

    摘要: A Fleming-type ink jet head in which a group of electrodes constituting one of two rows of a plurality of pairs of electrodes for causing currents to flow across ink channels are integrally formed for the purpose of improving the accuracy with which the pairs of electrodes are relatively positioned as well as reducing the manufacture cost. The resistance between each of the pairs of electrodes is detected and the width or magnitude of a pulse current caused to flow between the electrodes is controlled based on the data of this detection, thereby preventing a deterioration in printing quality due to the non-uniformity of the resistance. Also, the width or magnitude of current pulse is controlled with respect to the positions of the channels to compensate for the non-uniformity of the magnetic field intensity through the channels stacked between magnets, whereby a deterioration in printing quality due to the non-uniformity of the magnetic field intensity is prevented. A circuit for heating the ink in the channels is provided to prevent a deterioration in printing quality due to a change in the viscosity of the ink.

    摘要: A hologram is produced by arranging a plurality of two-dimensional pictures in a predetermined pattern, illuminating each of the two-dimensional pictures with a coherent beam, projecting light emerging from each of the two-dimensional pictures to a screen, a dispersing light on the screen in one direction parallel to the screen and redirecting the light along predetermined courses in the direction parallel to the screen but orthogonal to the one direction so as to form overlapping images of the two-dimensional pictures on the screen. The light from each picture is then redirected onto different positions of a holographic recording medium, and a reference beam is directed toward the medium so as to produce interference with the light from the screen. In one embodiment the screen reflectively disperses the light in the vertical direction and redirects it retroreflectively in the horizontal direction.
