    • An abnormality detection circuit for detecting abnormality of a CPU includes a command value check circuit for checking whether a current command value calculated by the CPU is normal or abnormal with respect to a torque signal, and a drive signal check circuit for checking whether a motor drive signal outputted based on the current command value is normal or abnormal. When the command value abnormality of the CPU is detected by the abnormality detection circuit, a counter circuit is started to count a time of an abnormality state of the CPU. If the counted time reaches a predetermined time, a control stop command is outputted from a system stop circuit to the CPU, thereby stopping the system control of the CPU.
    • 用于检测CPU的异常的异常检测电路包括用于检查由CPU计算的电流指令值是否相对于转矩信号正常或异常的指令值检查电路,以及用于检查电动机驱动 基于当前指令值输出的信号正常或异常。 当异常检测电路检测到CPU的指令值异常时,开始对CPU的异常状态的时间进行计数的计数器电路。 如果计时时间达到预定时间,则从系统停止电路向CPU输出控制停止命令,从而停止CPU的系统控制。

    • The present invention provides a light scattering film, including a plurality of first transparent regions each having a fibril-like cross section, and a plurality of second transparent regions differing in refractive index range from the first transparent region, wherein each of the first transparent regions is positioned to permit the long axis of the fibril-like cross section to cross one main surface of the film and to permit each of the fibril-like cross sections of the first transparent regions to be sandwiched between adjacent second transparent regions in a direction of the short axis of the fibril-like cross section. The present invention also provides a liquid crystal display device, having a liquid crystal panel and a light scattering film formed on one main surface of the liquid crystal panel.
