Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To enable a mobile station to maintain an excellent reception state with simple constitution by allowing an earth station of a system wherein a mobile station receives orthogonal polarized waves through a geostationary satellite, to occupy vertical and horizontal polarized waves of the same fre quency and send a pilot signal, usable to recognize and track the geostationary satellite and detect the tilt of an antenna polarizing plane, within the band. SOLUTION: The vertical and horizontal polarized waves V and H from the earth station as a ground CS broadcast station are repeated by the geostationary satellite and send all over Japan. Each mobile station when changing its direction during a travel rotates the Z axis of its antenna to track the satellite. A provider for CS broadcasting borrows the vertical and horizontal polarized waves V and H of the band of a transponder which is not engaged and sends a single carrier PS as a pilot signal. For example, different pilot signal bands Bp are allocated by different geostationary satellites. A mobile station detects the maximum electric power of the single carrier PS and tracks the geostationary satellite.

Abstract: PROBLEM TO BE SOLVED: To automatically control an X-ray radioscopy picture in an optimum state even if an X-ray irradiation field is converged to be less than a photometry area in a collimator by detecting the leaf opening of the collimator and correcting a luminance signal in accordance with the covering rate of a leaf for the photometry area of average luminance based on the detected opening. SOLUTION: A leaf opening detector 13 detects the opening of the leaf 4' of the collimator regulating the X-ray irradiation field. A correction circuit 12 corrects a luminance signal I in accordance with the covering rate of the leaf 4' for the photometry area of average luminance based on the opening signal. Namely, the opening signal detected in the leaf opening detector 13 is supplied to an IBS (illuminance) control circuit 11 and whether the leaf 4' of the collimator 4 covers the photometry area or not is judged.
