Appeal No. 1997-4087 Page 2
Application No. 08/298,375
BACKGROUND
The invention at issue in this appeal relates to a print
head used in an ink jet printer. More specifically, the
invention is a technique for adhesively bonding the orifice
plate and the channeled body of such a print head.
Pressure inside a conventionally manufactured print head
can separate the print head’s orifice plate from its channeled
body. Heretofore, the problem of separation has demanded the
use of adhesives having a great bonding strength. Because
such adhesives are costly, however, their use increases the
cost of manufacturing a print head. The invention strengthens
the bond between the orifice plate and channeled body of an
ink jet print head without requiring the use of the costly
adhesives.
Claim 1, which is representative for our purposes,
follows:
1. A method of fabricating a print head
assembly for use in an ink jet printer, said method
comprising the steps of:
