    • In a convergence distortion correction method and apparatus for raster-scanned color CRT having a dynamic convergence magnet assembly, the CRT display screen is divided into a plurality of zones. A digital memory is provided with a data storage field and a flag bit field at each address. Addresses of the zones are generated by means of a sync signal regenerated from an input video signal. First, the addresses of zones to be subjected to the adjustment of convergence distortion are selected to set flags in the flag bit fields of the digital memory at its addresses specified by the selected zone addresses. Then, by referring to the flags, guide patterns are displayed on the selected zones and are used to adjust the convergence distortions in those zones. Preferably, one of the displayed guide patterns is flickered. Correction data based on the results of the adjustment are stored in the data storage fields of the digital memory at the corresponding addresses. Correction data for zones other than the selected zones may be interpolated from the correction data for the selected zones.
    • 在具有动态会聚磁体组件的光栅扫描彩色CRT的会聚变形校正方法和装置中,CRT显示屏被分成多个区域。 数字存储器在每个地址处提供数据存储字段和标志位字段。 通过从输入视频信号再生的同步信号产生区域的地址。 首先,选择要进行调整收敛失真的区域的地址,以在由所选区域地址指定的地址的数字存储器的标志位字段中设置标志。 然后,通过参照标志,在所选区域上显示引导图案,并用于调整这些区域中的收敛失真。 优选地,显示的引导图案中的一个闪烁。 基于调整结果的校正数据存储在相应地址的数字存储器的数据存储区域中。 可以从所选区域的校正数据内插用于所选区域以外的区域的校正数据。

    • A mobile station, operable in a mobil communication system that executes a location registration processing by using the channel quality of a base station and an information concerning a base station the mobile station includes a base station information memory unit for storing therein information concerning a plurality of base stations and an amount in which the channel quality of the base station is changed with time and a location judging unit for judging on the basis of the amount in which the base station information is changed with time and which is stored in the base station information memory unit whether or not location registration processing is to be executed indicating a location in service area. Whether the location registration processing is to be executed or not is determined in accordance with the moving speed of the mobile station, thereby limiting the occurrence of a location registration request which becomes invalid with a large possibility in a short period of time because the mobile station moves to another location registration area or to the calling area in a short period of time.
