To account for this deficiency, the examiner relies on the
teachings of either Suzuki or Wu. See the Answer, pages 3-4. We
find that Suzuki teaches an impingement atomizer “for various
uses in which atomization of a liquid is required,” including a
cooling system. See column 1, lines 5-12 and 53-55, column 2,
lines 55-58 and column 4, lines 23-46. This impingement
atomizer, according to column 1, lines 11-17 and 27-39, of
Suzuki, obviates various problems associated with the single-
fluid nozzles. We find that Suzuki specifically teaches (column
1, lines 27-39) that:
The single hole injector is formed by drilling,
electric discharging or other known techniques. With
these known techniques, however, it has been difficult
to form a nozzle port having a diameter of less than
0.1 to 0.05 mm. In addition, it has been quite
difficult to maintain the required precision in this
size of nozzle port when the atomizer is mass-produced.
Furthermore, an atomizer having an injector with a
single nozzle port tends to become clogged with foreign
matter and, hence, it is necessary to filtrate the
liquid by a filter or strainer of fine mesh in order
to trap the foreign matter. Besides, the single hole
injector is not suitable for obtaining a high rate of
atomization.
We find that Suzuki teaches that its impingement atomizer avoids
“clogging of the atomizing injector while attaining high
precision of atomization...” See column 1, lines 11-17. We find
that Suzuki teaches that its impingement atomizer has “an
injector with fine nozzle ports finished with high precision...to
