equals 30 mechanical degrees. 360 mechanical degrees divided by 30 yields twelve
magnets.
11. Both ends of each magnet have an unmagnetized area. This fact is
shown by Appellants’ paragraph [00041]. The electrical angle of the magnetized portion
of the magnet is subtracted from 180 degrees to yield the electrical angle of the
unmagnetized portion of the magnet. The unmagnetized portions’ electrical angle is
then divided by two. Also, Fig. 7 shows that if column 2 is added to two times column 3,
the result is always 180 electrical degrees for each magnet.
12. Each end’s unmagnetized area occupies an electrical angle between 0
and 90 degrees (Column 3 of Fig. 7). Each unmagnetized area physically occupies a
mechanical angle between 0 and 15 degrees.
13. Each magnet center’s magnetized area occupies an electrical angle
between 0 and 180 degrees (Column 2 of Fig. 7). Each magnetized area physically
occupies a mechanical angle between 0 and 30 degrees.
14. Claim 7 recites that the electrical angle of each magnet pole lies in the
range 120 to 140 degrees of the 180 electrical degrees occupied by the magnet.
15. Thus, claim 7 covers where the magnetized portion of the magnet
occupies a minimum of 2/3 (or 6/9) of the 180 electrical degrees occupied by the
magnet and a maximum 7/9 of the 180 electrical degrees. The remainder of the 180
electrical degrees is unmagnetized.
16. Also, translated in terms of in terms of mechanical degrees where a
magnet occupies X mechanical degrees, claim 7 covers where the magnetized portion
of the magnet occupies a minimum of 2/3 (or 6/9) of the X mechanical degrees
