摘要： One frame of a color image data is resolved into three frames of R, G, and B colors, which are displayed in sequence. In synchronism with the R, G, B frames, a power supply voltage for displaying each of the three frames is altered to predetermined levels set for the respective frames. Output voltage data for determining the voltage levels for red-, green-, and blue-frame are stored in rewritable forms, which are provided to the power supply circuit so that its output voltage is equilibrated to a reference voltage based on that output voltage data provided. The invention enables suppression of color temperature deviation due to variations in transmissivity of color filters while setting a common gradation level for the R, G, an B frames.

摘要： In a slip frequency control system hitherto widely employed as a control system for an induction motor type electric rolling stock (in which a slip frequency is determined from a current deviation, an inverter frequency is calculated from the slip frequency and a motor rotation frequency, and the inverter frequency is multiplied by a predetermined correction factor to determine a modulation rate, thereby operating an inverter), a motor output torque decreases in a low speed region. It is difficult to make the correction for this decrease of torque by detecting the torque. In the present invention made considering that a torque curve and sin .phi. (.phi.: the internal impedance angle of a motor) obtained from the result of simulation resemble each other, the decrease of sin .phi. is regarded as being the decrease of torque and a voltage to frequency ratio is corrected so as to compensate for the decrease of sin .phi..
摘要翻译：在迄今为止广泛用作感应电动机型电动车辆的控制系统的滑差频率控制系统中（其中滑差频率根据电流偏差确定，根据转差频率和电动机转速频率计算变频器频率，逆变器频率乘以预定的校正因子以确定调制速率，从而操作逆变器），电动机输出转矩在低速区域中减小。通过检测转矩，难以进行扭矩减小的校正。在本发明中，考虑到从仿真结果得到的转矩曲线和sinφ（phi：电动机的内部阻抗角）彼此相似，本发明中，将sin phi的减小视为转矩的降低和电压对频率比进行校正，以补偿sin phi的减少。
