    • A washing machine includes a rotational tub, a single-phase induction motor driving the rotational tub in a dehydrating operation and having a main and an auxiliary coils, a speed detector for detecting a speed of the motor, thereby generating a detection signal, and an output changeover device for changing between an operation mode in which both of the main and auxiliary coils are excited and the other operation mode in which either the main or auxiliary coil is excited. When the motor speed is increased in the dehydrating operation, a control circuit controls the motor in a feedback manner. More specifically, in low and medium speed ranges, the control circuit executes a control pattern in which both of the main and auxiliary coils are excited and selectively executes another control pattern in which only the auxiliary coil is excited when necessary.
    • 洗衣机包括旋转桶,单相感应电动机,其在脱水操作中驱动旋转桶并具有主和辅助线圈,用于检测电动机速度的速度检测器,从而产生检测信号,以及 输出切换装置,用于在激励主励磁线圈和辅助线圈两者的操作模式之间进行切换,以及其中激励主辅助线圈的另一操作模式。 当脱水操作中电机速度增加时,控制电路以反馈方式控制电动机。 更具体地说,在低速和中速范围内,控制电路执行其中主励磁线圈和辅助线圈都被激励的控制模式,并且有选择地执行仅当需要激励辅助线圈时的其它控制模式。

    • The present invention relates to a display device and, more particularly, to an active matrix-type display device employing a line inversion drive scheme as a drive scheme.In a liquid crystal display device employing the line inversion drive scheme as a drive scheme, a predetermined video signals are applied to video signal lines in a predetermined period after start of a vertical blanking period. When a vertical scanning period starts in an even-numbered frame, a source potential (VS) decreases by ½ of amplitude in an effective video period. After the decreased source potential (VS) is maintained only for one horizontal scanning period, source bus lines are set to a high-impedance state. When a vertical scanning period starts in an odd-numbered frame, the source potential (VS) rises by ½ of amplitude in the effective video period. After the risen source potential VS is maintained only in one horizontal scanning period, the source bus lines are set to a high-impedance state.
    • 显示装置技术领域本发明涉及显示装置,更具体地,涉及采用线路反转驱动方案作为驱动方案的有源矩阵型显示装置。 在采用线路反转驱动方案作为驱动方案的液晶显示装置中,在垂直消隐期间开始之后的预定时段内,对视频信号线施加预定的视频信号。 当垂直扫描期间以偶数帧开始时,源极电位(VS)在有效视频周期内减小振幅的1/2。 在仅在一个水平扫描周期内维持降低的源极电位(VS)之后,源极总线被设置为高阻抗状态。 当在奇数帧中开始垂直扫描期间时,源电位(VS)在有效视频周期中上升幅度的1/2。 在上升的源极电位VS仅保持在一个水平扫描周期之后,源极总线被设置为高阻抗状态。
