the single (microcomputer) generator claimed. And further, no
single microcomputer can be found in Karlin. Even if certain
circuitry of Karlin could be considered equivalent to a
microcomputer, one would end up with an equivalent
microcomputer for each motor rather than a single equivalent
microcomputer. The only control circuit common to all motors
of Karlin is the variable frequency oscillator 55. We do not
consider oscillator 55 to be equivalent to a microcomputer.
Yamaguchi discloses a controller 30 which generates
drive signals and the Examiner proposes to combine Yamaguchi
with Karlin to obtain the aspects of Pulse Width Modulation.
Controller 30 may be a microprocessor, see column 4, lines 54
and 55. Assuming Yamaguchi’s microprocessor is equivalent to
a microcomputer , and there is sufficient rationale to combine2
2According to the Dictionary of Computers, Information
Processing & Telecommunications, pages 382 and 384, (1987), a
microprocessor is part of a microcomputer, a microcomputer
contains a microprocessor and more.
