    • A horizontal sync pulse control circuit for a video tape recorder of the type utilizing pulse code modulation in a standard format, where there is a fixed time interval between each horizontal sync pulse and the beginning of the data pulse train for the corresponding video line. Delay circuitry and associated signal process circuitry is used to monitor this time interval. When the monitored time interval between the horizontal sync pulse and the first data pulse for the corresponding line differs from the correct time interval by one bit or less, the position of the horizontal sync pulse is re-synchronized utilizing a clock locked to the video signal. When the interval between the horizontal sync pulse and the first data pulse of the corresponding line exceeds one bit, the horizontal sync pulse is blanked, so that noise which would otherwise be produced by an incorrect horizontal sync pulse is eliminated.
    • 一种用于采用标准格式的脉冲编码调制类型的录像机的水平同步脉冲控制电路,其中在每个水平同步脉冲与对应的视频行的数据脉冲序列的开始之间存在固定的时间间隔。 延迟电路和相关信号处理电路用于监视此时间间隔。 当水平同步脉冲与相应线路的第一数据脉冲之间的监视时间间隔与正确的时间间隔不同一位或更少时,水平同步脉冲的位置将利用锁定到视频信号的时钟来重新同步 。 当水平同步脉冲与对应行的第一数据脉冲之间的间隔超过一位时,水平同步脉冲被消隐,从而消除了由错误的水平同步脉冲产生的噪声。

    • An information device for use with an engine of a vehicle includes a lighting device for providing information about a power position of the vehicle, an engine running detection device for detecting engine running, a gear shift position detection device for detecting gear shift position, and an illuminance control device for controlling illuminance of the lighting device. When a detection is made by the engine running detection device that the engine is running and by the gear shift position detection device that the gear shift position is other than in a P or N range, the illuminance control device reduces the illuminance of the lighting device compared with the illuminance of the lighting device when the gear shift position is in the P or N range.
