the other direction.
Thus, as broadly set forth in instant claim 1, Saito clearly
shows a controller which controls an electrification period of
time (the width of one pulse in Figure 3(A)) and an
electrification start time (the beginning of the pulse in Figure
3(A) of Saito) of the high-speed electrifying circuit (Figure 3
(A)-expansion) and the low-speed electrifying circuit (Figure 3
(B)-contraction).
Since claim 1 recites nothing about changing time periods or
about relative lengths of periods of time between low-speed and
high-speed electrification periods of time, we find that Saito
does, indeed, disclose the instant claimed subject matter.
However, when it comes to instant claim 2, we find nothing
in Saito about setting a low-speed electrification period of time
to be a first period of time and a period of time from a low-
speed electrification start time to a high-speed electrification
start time to be at a second period of time, for a first driving
speed, and wherein for a second driving speed, the low-speed
electrification period of time can be set shorter than the first
period of time and can set the period of time from the low-speed
electrification start time to the high-speed electrification
