For its part, Seki teaches the problem of ripple voltage
components included in power supplies. Specifically,
“fluctuation of the voltages,” col. 2, l. 42, are caused “by
the ac ripple component included in the source voltage . . .
.” Id. at ll. 43-44. The latter reference further teaches a
solution to the problem. Specifically, "[t]o the
interconnection point 1b' is connected a capacitor C for
2
removing the source voltage ripple, which forms a CR filter
circuit with the resistor R . This prevents the fluctuation
1
of the voltages at interconnections 1a' and 1b' by the ac
ripple component included in the source voltage V applied to
cc
the source voltage supply terminal 1a.” Id. at ll. 38-45.
Because De La Plaza’s generator includes a power supply,
and Seki teaches a problem troubling power supplies and a
solution thereto, we are persuaded that the prior art as a
