Appeal No. 2001-0713
Application 09/016,304
Accordingly, this appeal is directed to the rejection of claims
1-8.
The disclosed invention pertains to the field of
piezoelectric ceramic transformers. More particularly, the
invention relates to a piezoelectric ceramic plate having an
outer shape of a disk which can be driven in a radial direction
expansion vibration basic mode. The invention also relates to a
piezoelectric ceramic plate having an outer shape of a square
plate which can be driven in a contour direction expansion
vibration basic mode.
Representative claim 1 is reproduced as follows:
1. A piezoelectric ceramic transformer comprising:
a piezoelectric ceramic plate having an outer shape of a
disk, wherein:
said piezoelectric ceramic plate is divided, where circular
surfaces of said piezoelectric ceramic plate are defined as
principal surfaces, in a thickness direction into two regions
parallel to said principal surfaces and one of said two regions
is formed as a driving part while the other region is formed as a
generating part, and each of said driving part, and said
generating part forms a layering structure which comprises a
plurality of inner electrode pairs formed in parallel to said
principal surfaces and opposing each other in the thickness
direction and regions between the inner electrodes, said regions
between the inner electrodes being polarized so that any adjacent
ones of said inner electrodes may have opposite polarization
directions to each other;
