support of the rejection, and to the refiled brief2 (Paper No. 11, filed June 5, 2003) for
the appellant's arguments thereagainst.
OPINION
In reaching our decision in this appeal, we have given careful consideration to
the appellant's specification and claims, to the patent to Uemura, and to the respective
positions articulated by the appellant and the examiner. As a consequence of our
review, we make the determinations which follow.
Uemura's invention relates to an electromagnetic locking type actuator. Figure 1
illustrates a first embodiment of Uemura's invention, partly in section. A plunger shaft 1
and a disc-shaped armature 2 fitted at an end thereof constitute a reciprocable control
member. A tubular inner yoke 3 has mounted thereon a permanent magnet 4 and an
electromagnetic coil 5. The permanent magnet 4 is held between a tubular outer yoke 6
and an annular side yoke 16. An electromagnetic coil 5 is held between the inner yoke
and the outer yoke 6. Uemura teaches (column 1, line 65, to column 2, line 24) that:
The inner yoke 3, the outer yoke 6, a flat portion 2a and a conical portion 2b of
the disc-shaped armature 2, and a gap 7 between a tapered portion 3a of the
inner yoke 3 and the conical portion 2b of the disc-shaped armature 2 form a
magnetic path for passage of flux generated by the permanent magnet 4 and the
2 A postcard receipt submitted with the refiled brief establishes that the original brief (apparently
lost in the Office) was received by the Office on October 7, 2002.
