    摘要： A tape guide construction of a head drum of a video-cassette recorder comprising a circular wire fixedly engaged in a V-shaped groove formed at an outer peripheral surface of a lower drum of the head drum. A portion of the peripheral surface of the circular wire is disposed outside the V-shaped groove, whereby a tape is contacted at the lower edge thereof with and guided by the upper-protruded portion of the peripheral surface of the wire, during the travel thereof.

    摘要： This invention relates to novel compositions comprising a protective polymer layer and a UV blocking agent. This is used in the fabrication of electronic devices using thick film pastes. The present invention is also an electronic device fabrication process using the compositions. The protective polymer layer is fabricated from materials, which are insoluble after irradiation in the ester-type solvents contained in the thick film paste. By appropriate selection of protective film polymers, the protective film can be compatible with the thick film paste and can be further used to shield portions of the thick film paste from UV irradiation.

    摘要： A laser disk player performs a pause operation using a frequency generation (FG) pulse, frame address data read out from a disk and a vertical sync signal. A memory stores the frame address data read out at the time when a pause key signal is inputted. A microprocessor controls the pickup to jump back one track to the previous track and compares the currently read-out frame address data with the frame address data stored in the memory, to check the operation state of the frequency generator. If it is judged that the frequency generator for generating the FG pulse is operating abnormally, the microprocessor receives a vertical sync signal and controls the one-track jump operation of the pickup until the frame address data at a time of the pause is larger than or is equal to the frame address data read out via the one-track jumped pickup. Thus, the laser disk player performs a pause function reliably even if the frequency generator for generating the FG pulse operates abnormally.

    摘要翻译： 激光盘播放器使用频率产生（FG）脉冲，从盘读出的帧地址数据和垂直同步信号来执行暂停操作。 存储器存储在输入暂停键信号时读出的帧地址数据。 微处理器控制拾取器将一个轨道跳回到前一个轨道，并将当前读出的帧地址数据与存储在存储器中的帧地址数据进行比较，以检查频率发生器的操作状态。 如果判断用于产生FG脉冲的频率发生器运行异常，则微处理器接收垂直同步信号并控制拾取器的单轨跳转操作，直到暂停时的帧地址数据大于或 等于通过单轨跳跃拾取器读出的帧地址数据。 因此，即使用于产生FG脉冲的频率发生器异常地操作，激光盘播放器也可靠地执行暂停功能。
