Application No. 08/441,948
paper making process and a two sideness [sic, sidedness]
shrinkage difference in the crossing direction ranging from
0.02 to -0.02%.” See claim 7. These shrinkage properties
allow the electrophotographic transfer paper to avoid or
significantly reduce “post fuser curl.” See Specification,
pages 5 and 6. While the claimed two sidedness shrinkage
difference is obtained by “controlling the paper making speed
or the rate of dehydration,” the claimed shrinkage of not more
than 0.45% in transverse direction is obtained by providing
an appropriate force of constraint in cross (transverse)
direction “that is associated with the T/Y ratio.” See
Specification, page 12. T/Y ratio means velocity of
propagation of ultrasonic wave in machine direction/velocity
of propagation of ultrasonic wave in cross (transverse)
direction. See Specification, page 11. The Rule 132
declarations executed by Koichi Makiyama referred to by both
appellants and the examiner echo that view by showing that
drying a paper under constraint in a cross direction is
critical in obtaining the claimed shrinkage properties,
particularly the desired shrinkage of “no more than 0.45%” in
a cross direction.
