11) Acupuncture using electroconductive liquid 1-48-98069-02 adhesive 4 to form a foam
coalescence. The lead electrode 5.5 'was attached to one part of the silver electrode 3 and the
diaphragm plate, and connected to the oscillation circuit 6 to be M and a model of the L-1 short
cut. 7) It generates a bending vibration like a 7 7 In addition, as shown in FIG. 1 (I), the
piezoelectric element 2 is polarized in the direction of the arrow by applying high voltage% W8

worthy to the silver paste for electrodes, and it is the evil one of a step suspicious? J Phase is full
of all prices. y1 接着 adhesion R] is also a mixture of silver primary and polymer phase material
+1. ! It is priceless to raise the price. The present invention eliminates oblique defects [--saving of
ytVtr view, the purpose is to divide the cost of the piezoelectric element in the process, to make a
step on the defect pi, and to make the cost to δ etc. The low range of According to the feature of
the present invention, piezoelectric 2-48-98069- [) 3 '"-°" "" is used as a filling agent, and its
performance as a vibrator is secured without lowering its performance. And As described in the
second embodiment, as shown in the second embodiment, the piezoelectric element 2 having a
silver electrode of 3 only on one side as shown by the second failure ial is sandwiched between
the pressure electrode 9.9 'and the high pressure browning 8 , Separate processing in the
direction of the arrow. Without the S-append electrode, it is necessary that the entire surface be
in contact with the pressure electrode 9 ', and the surface should be covered with a conductive
rubber. Next, the side without silver electrode of It's outer membrane 2 that has been treated
with 萌 Ae as a second bad ial is referred to, and it is better than the one where the latitudinal
plate is pulled out at the root or ぺ side The frequency of the vibration l is non-conductive, that of
the housing 7 ′ ′ is 1 ′, the thin 7 ′ ′ 7... ′ ー ー ー 2 付 兄 兄 兄 h16 h.
Even if it is a non-leader, it's a very good contact with the joint surface, so J! ! l λ + mouth Jfij:
No problem in practical use. Oscillation frequency by ff and IIIV. , 6 can supply a signal of the
required river wave number, and resonate with the phase opening vibration of the desired
position to make it possible to absorb light on the next required sound slope. 3-; -48-98069 = 04,
hereinafter, 85φxo, 5t piezoelectric element and 5oφxo, st phosphor blue number are described
for convenience of the present invention and the conventional example in comparison with that
of the conventional example. Connect the grip base Ill consisting of the above dimensions as
shown in Fig. 4 and set the solid resistance of luΩ in series to adjust the oscillator 6. 【, 看 2 シ

body 111 was measured on the invention holier cigarette% fg 43 ′ ′ by static dissipation [7].
The characteristic side foot results of the core assembly of the present invention and the
conventional example are shown in FIG. As is apparent from the above, the resonance impedance
IZ + is considered to be hardly different between the present invention and the conventional
example, and there is no difference in performance when used as a father's body. According to
the effect of the present invention, as the effect of the present invention, the sound wave 4-0
wave 4B-98069-soot or the ultrasonic wave is hardly deteriorated compared to the present
invention prior to the present invention in terms of performance-Silver in the piezoelectric
element By making the two-sided baking of the electrode one-sided baking reduces the weight
and the free hitting process to half, so that the yield due to cracking, defects, etc. is directed, and
the required amount of silver paste is combined with the improvement of the yield. It is less than

the reduction of the cost. 4, the detailed description of the Figure 2 Figure 1a + shows the
