    • There is provided a soft start circuit including: a resonator generating a resonant voltage; a voltage detector detecting an output voltage of a power converter; a reference voltage selector selecting one of a voltage detected by the voltage detector and the resonant voltage as a reference voltage, based on a driving signal for turning the power converter on or off; and an error amplifier generating a control signal for controlling the output voltage of the power converter from the reference voltage selected by the reference voltage selector and the voltage detected by the voltage detector. The soft start circuit is capable of preventing semiconductor devices of the power converter from being burned out and preventing overshooting of the output voltage.

    • The present invention discloses a method of releasing a roughened surface of a washed cloth (21) which can prevent a cloth (21) with fibers protruding therefrom from being roughened due to fiber lumping after washing. The method of releasing the roughened surface of the washed cloth (21) generated when the cloth (21) is rubbed with wash water filled in a tub (10) by rotation of a drum (20) includes a first step of discharging the wash water from the washed cloth (21) to the tub (10), by rotating the drum (20) so that the washed cloth (21) can stick to the drum (20), and a second step of solving fiber lumping of the washed cloth (21), by using the motion of the washed cloth (21) by a frictional force between the rotated drum (20) and the washed cloth (21) by rotating the drum (20).
    • 本发明公开了一种洗涤布(21)的粗糙化表面的释放方法,其可以防止由于在洗涤后的纤维结块而从其上突出的纤维粗糙化的布(21)。 当通过滚筒(20)旋转而将布(21)与填充在桶(10)中的洗涤水一起摩擦时产生的洗涤布(21)的粗糙表面的释放方法包括:第一步骤, 通过使滚筒(20)旋转以使洗涤的布(21)能够粘附到滚筒(20)上,从洗涤的布(21)到盛水桶(10),以及解决洗涤布的纤维结块的第二步骤 (21),通过旋转滚筒(20),通过旋转的滚筒(20)和洗涤布(21)之间的摩擦力来使用洗涤布(21)的运动。
