Application 10/931,274
motor. Appellants further argue that the language of claims 8 and 16 requires
the output to be delivered to the second transformation block (Br. 5).
The Examiner disagrees. The Examiner points to signal J1, i.e., the
output of position sensor 2, fig. 1. The Examiner further points to output
signal “θ1” from block 21b, i.e., where signal “θ1” is the output of the
ARCTAN function shown in fig. 8 (Answer 6).
We note that Kojima discloses a summation block (i.e., subtractor 16,
fig. 1) that receives a first “θ1” signal from “PHASE CORRECTION
SETTING CONTROL UNIT 49” and a second “Th” signal from “PHASE
COMPUTING UNIT 9” (fig. 1), as follows:
Still further, numeral 9 denotes a phase computing unit for
performing an operation of an electric angular phase (Th) of the
rotor on the basis of the position output (J1) of the absolute
position detector 2, with this electric angular phase (Th) being
indicative of a rotational angle in the d-q axis coordinate system
viewed from an α–β where the phase axis coincides with the u
phase axis of the three phases.
(col. 1, l. 66 through col. 2, l. 5).
We note that the output of the summation block (i.e., subtractor 16,
fig. 1) is provided as an input to “TWO-PHASE / THREE PHASE
CONVERTER 4” (i.e., the output of the summation block is delivered to the
second transformation block). (See also Kojima, col. 6, ll. 29-33).
Therefore, we agree with the Examiner that the language of claims 8 and 16
broadly but reasonably reads on Kojima’s disclosure. Because we find that
Kojima discloses all that is claimed, we will sustain the Examiner’s rejection
of claims 8 and 16 as being anticipated by Kojima.
