  • Patent number: 9231730
    Abstract: A radio communication device includes a first antenna, a second antenna, a phase varying section that varies a phase of a first RF signal received by or transmitted from the first antenna, and a phase control section that causes the phase varying section to vary a phase amount, which is a varied amount of the phase of the first RF signal received by or transmitted from the first antenna. Thus, it is possible to prevent the size of a device configuration from increasing and avoid the lowering of a reception electric field level in a localized area.

  • Publication number: 20150360455
    Abstract: The present invention provides a method of applying a photocurable resin on a surface of a panel. A difference in a surface level is formed on a peripheral portion on the surface of the panel. The method includes a step of moving either one of an application head and the panel so that the application head provided with a slit-type nozzle which discharges a photocurable resin relatively moves on the surface of the panel, and an application step of discharging the resin from the nozzle onto the surface of the panel during the moving step. In the application process, a film thickness of the resin is controlled so that a difference in a surface level is not generated on a liquid film surface of the resin on the difference in a surface level on the panel.

  • Publication number: 20150305696
    Abstract: An X-ray tomographic imaging apparatus includes an X-ray and a direct conversion type of detector. The X-ray tube and the detector are supported by the support means so as to be rotatable along curved orbits mutually independently. Under instructions from a computer, scans and image reconstruction are performed. The X-ray tube and the detector are moved along the orbits mutually independently so that X-ray beams are always transmitted through a desired tomographic plane of an object at desired angles. Acquired frame data are used to produce a panoramic image of the plane, while the frame data and the panoramic image are used to produce a tomographic image in which structural components of the object are optically focused and distortions caused due to differences in X-ray paths are suppressed. The apparatus can be used as devices for dental, medical diagnosis and nondestructive inspection, and can have a CT imaging function.

  • Patent number: 8891845
    Abstract: A panoramic imaging apparatus functionally includes an image processing apparatus. In this apparatus, two planar images are produced, which are subjected to registration. A registration process is applied to overall areas of two planar images based on curves decided from positions designated on the two planar images respectively. The positions on each of the planar images are aligned along a straight line, both straight lines corresponding to each other in a horizontal direction, and a scale factor for the registration is changed position by position on the straight lines. One of the two planar images is searched for a match of each local region of the other planar image, to any of regions of the one planar image, and images of the matched regions are re-produced to produce a planar image. The difference information is calculated between the planar images.

    Abstract: In the adaptive control apparatus, a computation unit computes weighting coefficients, using a first adaptive control method in a proportion ? of a first computation amount, where the first adaptive control method has a first convergence rate and a first convergence error. Further, a computation unit computes weighting coefficients from initial values of the weighting coefficients computed by the computation unit, using a second adaptive control method in a proportion (1??) of a second computation amount, where the second adaptive control method has a second convergence rate slower than the first convergence rate and a second convergence error smaller than the first convergence error. A controller controls determination of a ratio ?/(1-?) based on a moving speed of a mobile unit, and controls the computation units to perform computing processes.

  • Publication number: 20130114799
    Abstract: In the imaging space provided by a panoramic imaging apparatus, a phantom is arranged. The phantom is located to a predetermined tomographic plane and includes markers which image known positional information with an X-ray beam. The X-ray beam from an X-ray source is acquired as X-ray transmission data by a detector, and a panoramic image is produced using the data. Based on known positional information of the markers and information of marker positions in the panoramic image, distance information (Rs, Rd) between the X-ray tube and the detector and height information (B1) of the X-ray tube to the detector are calculated. From this calculated results and the acquired data, parameters (?x/?Fi, ?, ??/?Fi, D, A, CX, CY) defining positional relationships among the X-ray tube, the detector, and the tomographic plane are calculated such that amounts of changes in the position connecting the X-ray tube and the detector are considered in the parameters.
