Appeal No. 1998-1695
Application No. 08/421,309
BACKGROUND
The appellants’ invention relates to an apparatus and method for measuring rotation
quantity of a spherical object. An understanding of the invention can be derived from a
reading of exemplary claim 1, which is reproduced below.
1. An apparatus for measuring rotation quantity of a spherical object,
provided with a recording means photographing and recording a rotating
spherical object from one definite direction as a plurality of stationary circular
images, an instrumentation means measuring positions of definite two
points in each of the plurality of stationary circular images recorded by said
recording means, and an arithmetic unit calculating rotation quantity of the
spherical object on each axis of a three-dimensional coordinate-system on
the basis of the positions of the definite two points in each of the stationary
circular images.
The prior art references of record relied upon by the examiner in rejecting the
appealed claims are:
Kobayashi et al. (Kobayashi) 4,987,299 Jan. 22, 1991
Nishiyama et al. (Nishiyama) 5,568,250 Oct. 22, 1996
(filed May 26, 1994)
Claims 1-13 stand rejected under 35 U.S.C. § 103 as being unpatentable over
Nishiyama in view of Kobayashi.1
1The examiner does not state the section of Title 35 upon which the claims are rejected, but
references paper number 9 which sets forth 35 U.S.C. § 103(a) as the basis of the rejection.
