the first period of time.”
In order to support these explicit claim limitations, the
examiner points to Figures 3(A) and 3(B) of Saito, declaring that
the controller 20, 30
can set a low-speed electrification period of time to
be a first period of time (fig. 3B, rise time) and can
set a period of time from a low-speed electrification
start time to a high-speed electrification start time
to be a second period of time (fig. 3B, fall time)
wherein said controller (20, 30), for a second driving
speed, can set (fig. 3A, rise time) the low-speed
electrification period of time to be 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 start time to be shorter
than the second period (falling edge, figure 3A) of
time; and wherein said second driving speed is lower
than said first driving speed [answer-pages 2-3].
It is true that Saito uses a driving circuit for applying a
voltage to the transducer so as to make the speed of expansion of
the transducer different from the speed of contraction. It is
also true that Figures 3(A) and 3(B) of Saito show waveforms of
driving pulses applied to the transducer wherein 3(A) relates to
rapid expansion and 3(B) relates to contraction. Saito is
disclosing that the transducer element 12 has a voltage waveform
applied to it in order to move a lens barrel 1 in a leftward or
rightward direction. In one direction, the speed of expansion is
used and it will be different than the speed of contraction in
