Appeal No. 1998-1418
Application 08/313,249
APPENDED CLAIMS
1. An ultrasonic atomizer comprising:
an ultrasonic pump comprising a pump shaft having an
upper end, a lower end, and a pump bore passing axially through
said pump shaft to form openings in the upper and lower ends,
said ultrasonic pump further comprising an ultrasonic vibrator
mounted on said pump shaft substantially at a midpoint thereof
with respect to the axial direction of said pump shaft;
a liquid vessel arranged such that it is penetrated by
a lower end of said pump shaft;
a mesh plate placed on a face of the upper end of said
pump shaft, said mesh plate having a plurality of minute holes;
and
a resilient biasing member for biasing said mesh plate
toward the upper end face of said pump shaft, said mesh plate
intermittently contacting the upper end face of said pump shaft.
28. An ultrasonic atomizer in which a liquid inside a
liquid vessel is supplied to an inlet side of a mesh plate formed
to have a plurality of minute holes and said mesh plate is
vibrated by an ultrasonic vibrator, whereby the liquid supplied
to the inlet side of the mesh plate is sprayed from an outlet
side of said mesh plate, said mesh plate comprising a plate-
shaped body having a recess between mutually adjacent ones of
said minute holes, said plate-shaped body being formed such that
peripheral wall surfaces of said minute holes project from the
inlet side.
38. An ultrasonic atomizer having:
a liquid vessel for accommodating a liquid to be
atomized; and
an ultrasonic pump comprising a pump shaft having a
lower end situated inside said liquid vessel and formed to have a
pump bore passing through the pump shaft axially and having open
upper and lower ends, and an ultrasonic vibrator mounted on the
pump shaft;
