    • A video signal processing apparatus in which an input video signal is written in a frame memory on a line sequential scanning frame unit base in synchronism with a first vertical synchronizing signal and which the line sequential scanning video signal written in the frame memory is read out in synchronism with a second vertical synchronizing signal. The second vertical synchronizing signal having a frequency different from a frequency of a first vertical synchronizing signal is generated in synchronism with the first vertical synchronizing signal of a starting frame of five frames forming a pattern after the conversion in the 2-3 pulldown conversion system when it is judged that the input video signal is based on a telecine-converted video signal.
    • 一种视频信号处理装置,其中输入视频信号与第一垂直同步信号同步地在行顺序扫描帧单元基础上写入帧存储器中,并且读出写入帧存储器中的行顺序扫描视频信号 与第二垂直同步信号同步。 产生与第一垂直同步信号的频率不同的频率的第二垂直同步信号与在2-3下拉转换系统中的转换之后的五个帧的起始帧的第一垂直同步信号同步生成, 判断输入视频信号是基于电视电影转换视频信号的。

    • An extracorporeal circulation device having high safety without increases in the circuit scale and the power consumption includes a main control unit responsible for control of a motor drive circuit so as to yield a blood flow rate per unit time set by a user. The motor drive circuit applies a drive signal corresponding to the set blood flow rate to a motor. A sub-control unit configured by a field programmable gate array (FPGA) detects the drive signal applied to the motor and monitors whether or not the drive signal falls within an allowable range corresponding to the set blood flow rate. If the drive signal outside the allowable range is applied, the main control unit is deemed to be in an abnormal state and the main control unit is completely stopped. Then, the sub-control unit takes over the subsequent processing.
    • 具有高安全性而不增加电路规模和功耗的体外循环装置包括负责控制电动机驱动电路以便产生由用户设定的每单位时间的血液流量的主控制单元。 电动机驱动电路将与设定的血液流量对应的驱动信号应用于电动机。 由现场可编程门阵列(FPGA)配置的子控制单元检测施加到电动机的驱动信号,并监视驱动信号是否落在与设定的血液流量对应的允许范围内。 如果驱动信号超出允许范围,则主控制单元被认为处于异常状态,主控制单元完全停止。 然后,子控制单元接管后续处理。
