Appeal No. 96-2202
Application 08/117,088
This is an appeal from the final rejection of claims 2 and 4
through 10. In an Amendment After Final (paper number 17), 2
claims 5 and 8 were amended, and claims 2 and 4 were canceled.
Accordingly, claims 5 through 10 remain before us on appeal.
The disclosed invention relates to a superconducting bearing
device.
Claim 5 is illustrative of the claimed invention, and it
reads as follows:
5. A superconducting bearing device comprising:
a rotary body;
an annular permanent magnet portion disposed concentrically
with the rotary body, the permanent magnet portion having an end
face, the permanent magnet portion being provided on the rotary
body such that the magnetic flux distribution does not alter
around the axis of the rotary body, the permanent magnet portion
comprising a disk fixedly mounted on the rotary body and a
plurality of annular permanent magnets arranged on the disk at a
spacing radially of the rotary body, each of the permanent
magnets having axially opposite ends magnetized to polarities
opposite to each other, the permanent magnets adjacent to each
other being magnetized to polarities opposite to each other at
their ends positioned toward the same axial direction, and the
permanent magnets being spaced from each other 0.2 to 1.0 times
their width as measured radially; and
a superconductor opposed to the end face of the permanent
magnet portion and spaced apart therefrom axially of the rotary
body, the superconductor being arranged at a position spaced
apart from the permanent magnet portion and permitting a
2In view of the amendment, the 35 U.S.C. § 102(a) rejection
of claims 2 and 5 through 7 was withdrawn.
