Appeal No. 2001-1481
Application No. 09/088,976
extends and contracts in a predetermined direction (along driving
rod 17) and has a first end and a second end in the predetermined
direction. There is also a first member connected to the first
end of the transducer and a driving frictional member connected
to the second end of the transducer. Saito also discloses the
claimed second member frictionally coupled with the driving
frictional member and there is a driving pulse generating means.
Saito also has a high speed electrifying circuit and a low speed
electrifying circuit in order to enable a speed of expansion of
the transducer different from the speed of contraction thereof.
The point of contention between the examiner and the
appellant is in the last clause of the claim:
a controller which is capable of controlling an
electrification period of time and an electrification
start time of said high-speed electrifying circuit and
said low-speed electrifying circuit of said driving
pulse generating means.
In independent method claim 4, the language in contention is
that the transducer is electrified by a low-speed charging or
discharging during a first period of time and the transducer is
electrified by high-speed charging or discharging during a second
period of time and
“wherein the start time of the second period of time from
the start time of the first specified time is changed based on
