Appeal No. 1995-5010
Application 08/116,261
Examiner has not identified a sinusoidally oscillating voltage
source amplifier and even though Wilson teaches the concept of
tuning inductors for transducer driving circuits, it is not
seen how an inductor can be placed in Takahashi’s transducer
circuit to meet the above limitation. The closest the
Examiner comes to dealing with this issue is that “[t]he
tuning inductor 6 of Wilson certainly works for both types of
waves, since a square wave comprises a fundamental
(sinusoidal) component along with (sinusoidal) harmonics
(Wilson: column 6, line 55 et seq.) ” [supplemental answer,
page 3]. Appellant argues, and we agree, that Wilson’s quoted
passage does not teach the claimed sinusoidally oscillating
voltage source amplifier in combination with a parallel tuning
inductor resonance [brief, pages 6 to 8]. Furthermore, Ams
does not cure the deficiency of Takahashi and Wilson discussed
above. For these reasons, we do not sustain the obviousness
rejection of claim 1 and its dependent claims 2 to 4 and 6
over Takahashi, Wilson and Ams.
