Appeal No. 1999-2755
Application No. 08/599,105
with claim 5, as earlier indicated.
Claim 5 is drawn to a method of manufacturing a slider
body of a linear guide device, the linear guide device
including a guide rail and a slider having a body and a load
rolling-element rolling groove, the method comprising the
steps of grinding a groove surface of the load rolling-element
rolling groove, preparing a protecting member, the protecting
member being cylindrical and having a round surface, fitting
the protective member to the groove surface with at least a
portion of the round surface being brought in close contact
with at least a portion of the groove surface, while surfaces
of the slider adjacent the groove are not protected, and
thereafter subjecting the slider body to rust-proofing surface
treatment.3
Turning now to the evidence of obviousness, we are
informed by the appellant’s specification (pp. 5 and 6) that
it was known in the art prior to his invention to manufacture
a bearing slider by: machining a slider body to form mounting
3According to the appellant’s specification (pp. 19 and
20), the rust-proofing surface treatment is achieved by metal
plating or by applying a film of resin on the surface to be
protected.
