  • Patent number: 8067999
    Abstract: An electrical waveform adjuster capable of adjusting various voltage waveforms supplied to an electric apparatus to improve an operation capability of the electric apparatus, and to provide an electrical waveform adjuster capable of mitigating physical harmful effects on a user of the apparatus. The waveform adjuster can be provided either in a connection line between a power feeding line for feeding an alternating-current voltage to an electric apparatus and a power factor adjusting capacitor connected in parallel with the power feeding line, or in a connection line connected in parallel or in series with a power feeding line for feeding an alternating-current voltage to an electric apparatus. The waveform adjuster includes at least one mass comprised of a conductive material attached to the connection line, a ceramic outer frame formed to enclose the mass; and a non-conductive filling material provided between the outer frame and the mass.

    Abstract: An object of the present invention is to provide an electrical waveform adjuster capable of adjusting various voltage waveforms supplied to an electric apparatus to improve an operation capability of the electric apparatus, and also, to provide an electrical waveform adjuster capable of mitigating physical harmful effects on a user of the electric apparatus. As shown in FIG. 1A, an electrical waveform adjuster including a power factor adjusting capacitor 6 connected in parallel with a power feeding line 3 for feeding an alternating-current voltage to an electric apparatus, is characterized in that at least one or more low-resistance line sections having lower line resistivity than that of a connection line 4 for electrically connecting the power feeding line 3 and the power factor adjusting capacitor 6 are provided in the connection line as an adjusting circuit 5.
