    Abstract: In a display device of the invention, driving of the piezoelectric element is controlled to change the light path of the propagating light inside a light guiding plate. By illuminating a liquid crystal panel in this manner, an illumination time and a no illumination time can be provided for the liquid crystal panel within one frame period. This realizes impulse-type-like display in displaying moving images on the liquid crystal panel, and thereby improves an image quality of moving images. Further, since the light is used only in desired regions, spontaneous luminance can be improved and the light can be used more efficiently.

  • Patent number: 7073952
    Abstract: An optical alignment device holds fiber collimators in place with extremely good mechanical and environmental stability. The device includes a ball with a hole traversing the ball, an upper clamping block with a first inner concave spherical surface and a lower clamping block with a second inner concave spherical surface. The hole includes a shape that can accommodate or contact an optical component whose alignment is to be controlled. The ball, together with the enclosed optical component is firmly held between the first and second inner concave surfaces of the clamping blocks, which are tightened against the ball with screws. When firmly clamped within the concave surfaces, the ball is prevented from accidental movement but can still rotate about any axis to align the optical component. Once alignment is achieved, the optical component and the ball are secured in place by epoxy, glue, solder or other suitable adhesive.

    Abstract: An improved connector capable of transferring both energy and electrical signals between an energy generator and an energy transfer device is disclosed. The connector attaches the energy transfer device to the energy generator by rotation about a longitudinal axis. The connector carries at least one contact pad that has a surface on a plane parallel to the longitudinal axis. A line passing through the surface of the contact pad perpendicular to the plane is skew to the longitudinal axis, so that rotation of the connector engages the contact pad with conductive contacts associated with the energy generator in a direction substantially perpendicular to the contact pad.

  • Publication number: 20040247250
    Abstract: A pluggable connectorized package having an optical medium component and an optoelectronic element component in a sleeve. Alignment between these components may be maintained by the sleeve. The sleeve may have a slit, be slightly undersized relative to the components, and hold the components with a form of a grip. Or the sleeve may not have a slit and be machined along with the components to fit in the sleeve with close tolerances. The optical medium such as an optical fiber may be in a ferrule to be placed in the sleeve. The optoelectronic element may be in a ferrule-like device that may be referred to as a thimble. The thimble forms an environmentally protective housing for the original equipment chip with design options for full hermeticity as well as providing means of electrical interface. Additionally, this element may be configured to accommodate auxiliary chip-to-fiber coupling optics as required.

  • Patent number: 6827500
    Abstract: A precise fiber array is formed using a chuck to tightly hold as an array with hexagonal packing a group of precision ferrules into ones of which is inserted and bonded a fiber end. The bonding is typically performed by gluing the fiber into the ferrule. The ferrules may also be bonded to each other. Once the ferrules are bonded together, the chuck may be removed. The terminating end of the fibers may be polished. Alternatively, cleaved terminating fiber ends may be employed, with the various terminating ends being coordinated, e.g., by an optical flat. The ferrules may have a tip and a conical entrance. The chuck may hold the ferrules in a straight orientation. The fiber terminating faces of all of the ferrules may be substantially coplanar. The ferrules may be arranged in a hexagonal configuration.

  • Patent number: 6801694
    Abstract: A face alignment device of the present invention comprises two units that are each provided with: a convex semi-spherical block having a contact surface that makes contact with a clamp member for securing an object and a convex semi-spherical surface on the opposite side of the contact surface; and a base block having a concave portion corresponding to the semi-spherical surface of the convex semi-spherical block for rotatably holding the convex semi-spherical block, wherein the two units are arranged such that their contact surfaces face each other. The clamp member is attached to the contact surfaces of the respective units at eccentric positions from the center axes of the convex semi-spherical blocks. This is advantageous since a load required for rotational sliding between each of the semi-spherical surfaces of the convex semi-spherical blocks and each of the concave portions of the base blocks can be small.
