(brief, pages 8-9; reply brief, page 11). Kojima ‘546 prevents
bubbling by using heat in addition to ultraviolet rays (¶¶ 0028,
0041 and 0064). Regardless, the prevention of bubbles in
Kojima ‘919 pertains to curing optical fiber coatings (¶¶ 0241,
0246 and 0247). Slanting the ultraviolet rays in alignment with
the inclined adhesive used to join the prior art planar lightwave
circuit chip and optical-fiber block would have been prima facie
obvious to one of ordinary skill in the art as discussed above.
Kojima ‘546 discloses that the ultraviolet ray intensity is
detected by a photodetector (5) to control the ultraviolet ray
output to the level suitable for curing the particular adhesive so
that stable curing characteristics of the adhesive are obtained
(¶ 0024).
The appellants argue that Kojima ‘546 does not disclose or
suggest an optical sensor for measuring a power change or an
optical power meter for displaying the power change (brief,
pages 11-13; reply brief, pages 11-13). The Kojima ‘546 disclosure
that the ultraviolet light output is controlled based on the
ultraviolet light intensity detected by a photodetector (¶ 0024)
would have fairly suggested, to one of ordinary skill in the art,
using a photodetector which measures the change in ultraviolet
light intensity on which the control of that ultraviolet light
