  • Patent number: 10310159
    Abstract: In the case of implementing a polarization separation circuit, a polarization rotator, and the like by inserting a thin-film element into a substrate in one optical interference circuit, one common large-sized groove shared among a plurality of thin-film elements for their insertion has been formed. The optical waveguide type device of the present invention is configured such that at least one groove intersects only one corresponding optical waveguide for inserting the thin-film element and does not intersect other optical waveguides adjacent to the one corresponding optical waveguide. This groove substantially has a rectangular shape, and has a minimum size adapted to the thin-film element to be inserted so as to stably hold and fix the thin-film element in the groove. Adjacent grooves are formed so as to be arranged such that their portions in a direction substantially vertical to the optical waveguide are facing each other.

  • Cap
    Publication number: 20190165514
    Abstract: A cap for attachment to a fastener comprises a securing base removably supported on a neck portion of the fastener, a hinge portion connected to the securing base, and a covering portion connected to the hinge portion. The securing base has a plurality of elastic beams defining a head portion passageway receiving a head portion of the fastener. The neck portion has a smaller diameter than a largest diameter of the head portion. The elastic beams are elastically deformed by the head portion during passage of the head portion through the head portion passageway. The covering portion is movable between an open position exposing the head portion and a covering position covering the head portion and overlapping with the securing base.

  • Patent number: 10302483
    Abstract: The efficiency of the work for measuring electromagnetic waves is increased. A measuring device includes a position information obtaining unit, an electromagnetic wave information obtaining unit, a data storage unit, and a selecting unit. The position information obtaining unit obtains position information of a reflective prism 202, which is measured by a position measuring device 400. The electromagnetic wave information obtaining unit obtains illuminance information measured by an illuminometer 203, which is in the proximity of the reflective prism 202. The data storage unit stores the position information of the reflective prism 202 and the illuminance information in association with each other. The selecting unit compares information of predetermined measurement planned positions with the position information of the reflective prism 202 and selects the illuminance information at a position that has a specific relationship relative to one of the measurement planned positions.

  • Patent number: 7099511
    Abstract: An image data coding and decoding technique which realizes most efficient compression of the image data. The image data are input and separated into key frames and other intermediate frames. Per-pixel matching is computed between the key frames. A virtual intermediate frame between these key frames is generated by interpolating the matching-computed result. Difference is taken between the intermediate virtual frames and actual intermediate frames which have existed from the outset, so that the actual intermediate frames are encoded with the minimum quantity of codes.

  • Patent number: 7079710
    Abstract: An image input unit acquires a first image and a second image. A matching processor computes a pixel matching between the images so that corresponding points are obtained on the second image with respect to lattice points of a mesh defined on the first image. A result thereof is recorded as a corresponding point file. An intermediate image generator generates an intermediate image of the first image and the second image based on the corresponding point file. Since the corresponding point file is composed of corresponding lattice points alone rather than corresponding pixels or the like, the amount of data is relatively small, and thereby allows efficient implementation of and application to various image effects, motion picture compression, on-line commodity presentation, and mobile applications.

  • Publication number: 20030016871
    Abstract: An image input unit acquires a first image and a second image. A region setting unit sets a first region within the first image and a second region within the second image. A matching processor performs a matching computation between the first image and the second image. More specifically, the matching processor performs the matching computation between the first image and the second image using an internal constraint process for constraining the first region to be more likely to correspond to the second region.
