Application No. 09/868,150
New ground of rejection
Claims 7 to 10 are rejected under 35 U.S.C. § 102(b) as being anticipated by
Uemura.
Claim 7 is readable on Uemura as follows: Electromagnetic actuator (Uemura's
electromagnetic locking type actuator), having at least one electromagnet (Uemura's
electromagnetic coil 5) that acts on a correspondingly designed armature surface
(Uemura's conical portion 2b) of a moveable armature (Uemura's armature 2) in a first
effective range by way of at least one first conical and/or stepped pole face (Uemura's
tapered portion 3a of the inner yoke 3) using a magnetic field generated by at least one
coil (Uemura's electromagnetic coil 5), thereby forming a first magnetic flux, wherein
said first magnetic flux flows through a first working air gap (Uemura's gap 7),
characterized in that, shortly before the moveable armature (Uemura's armature 2)
reaches an end position, the electromagnet (Uemura's electromagnetic coil 5) acts on a
corresponding armature surface (Uemura's flat portion 2a of armature 2) by way of at
least a second pole face (Uemura's ring shaped projection 6a of outer yoke 6) in at least
a second effective range whereby a second magnetic flux is formed (a second magnetic
flux is inherently formed between Uemura's flat portion 2a of armature 2 and ring
shaped projection 6a of outer yoke 6 when armature 2 of Uemura is moved from the
position shown by broken lines in Figure 1 to the solid line position shown in Figure 1),
