    摘要： A control unit of a system stabilizing device uses a fluctuation detecting block (70A) to determine fluctuation components included in the active component and reactive component currents of a system current. The fluctuation detecting block (70A) is composed of a low-pass filter (71) for noise removal having first order lag characteristics with a time constant of T1, a low-pass filter (72) for setting a fluctuation detection time having first order lag characteristics with a time constant of T2, a subtracter (73) which performs subtraction between the output signals of the filter (71) and the filter (72) and outputs the difference, an amplifier (74) for amplifying the output of the subtracter (73), a rating limiter (75) for limiting the output of the amplifier, and an overcompensation inhibiting unit (200) which changes T4 to a smaller value when the rating limiter (75) performs a limiter action.

    摘要： A musical instrument is provided. When the lid is revolved in a direction to open the lid from a close state of the lid, the guided part is guided to an inner peripheral concave surface of the guiding channel and is engaged with the inner peripheral concave surface. The lid is supported by the bearing bar 30, and the lid is maintained being up. After the lid is revolved in a direction to further open the lid from the open state and the guided part is disengaged from the inner peripheral concave surface, the lid can be laid down by revolving in a direction for laying down the lid. Therefore, the lid can be changed to an open state or a close state by only revolving the lid.

    摘要： A control unit of a system stabilizing device uses a fluctuation detecting block (70A) to determine fluctuation components included in the active component and reactive component currents of a system current. The cut-off frequency on the high frequency side of the fluctuation detecting block (70A) is set to be f1; the cut-off frequency on the low frequency side is set to be f2; the time constant of a low-pass filter for noise removal which has a cut-off frequency of f1 is set to be T1; and the time constant of a low-pass filter for setting a fluctuation detection time which has a cut-off frequency of f2 is set to be T2. The fluctuation detecting block (70A) is composed of a low-pass filter (71) having first order lag characteristics with a time constant of T1, a low-pass filter (72) having first order lag characteristics with a time constant of T2, a subtracter (73) which performs subtraction between the output signals of the filter (71) and the filter (72) and outputs the difference, an amplifier (74) for amplifying the output of the subtracter (73), a rating limiter (75) for limiting the output of the amplifier, and an overcompensation inhibiting unit (200) which changes T4 to a smaller value when the rating limiter (75) performs a limiter action.
