    摘要: Signal input units 105a to 108a of antenna elements 105 to 108 are held on the essentially same circumference. Signal output units 113b, 113c, 114b, and 114c of a feeding circuit 102 are held on a line which is located perpendicular to a plane where the above-described circumference is located, and also which passes through an essential center of this circumference. The feeding circuit 102 supplies feeding signals to the antenna elements 105 to 108 while applying predetermined phase differences to these feeding signals. As a result, electric lengths of feeding lines 119A to 119D are made coincident with each other. These feeding lines are to connect the signal output units 113b, 113c, 114c to the signal input units 105a to 108a.

    摘要: A tracking servo apparatus for controlling a position of a light beam to follow an information track on an information storage disk. In response to a drive signal, a light-deflection mechanism moves the light beam onto the disk transversely with respect to the information track. The photodetector detects the difference in the intensity of the light beam in half sections and produces a radial error signal. The radial error signal is corrected in response to the drive signal which is applied to the light-deflection mechanism, and then a new drive signal is produced depending upon the corrected radial error signal.

    摘要: 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 (Δx/ΔFi, θ, Δθ/ΔFi, 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. This allows the parameters to be calibrated for 3D image reconstruction.

    摘要: An X-ray detector is provided with a plurality of modules each having a plurality of detection elements each composing a pixel, in which the detection elements convert incoming radiations to electric data depending on amounts of the radiations. The plural modules are mutually adjacently arranged on the same surface with a gap having a known width formed therebetween, such that the modules are arranged along at least one of a first X-axis and a first Y-axis, wherein the radiation detector is given a scan direction which is set along one of the first X- and Y-axes and the first Y-axis is perpendicular to the first X-axis. The plural detection elements of each module are two-dimensionally arranged along a second X-axis and a second Y-axis which are set obliquely to the first X-axis and the first Y-axis respectively and which are perpendicular to each other.

    摘要: 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.

    摘要: In the adaptive control apparatus, a computation unit computes weighting coefficients, using a first adaptive control method in a proportion α 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−α) 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 α/(1-α) based on a moving speed of a mobile unit, and controls the computation units to perform computing processes.
