DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote receiver
of a television receiver, a trolling device, an alarm, etc. Regarding improvement, especially,
ultrasonic transmission and reception IJ! The attachment of the net 1 to be arranged on the
frame relates to the structure aK. A conventional ultrasonic wave transducer is a ceramic
bimorph! A junction rotor is provided with an aluminum t> cone-like additional common ball or
resin-made vertical cross-section trapezoidal shape additional coupe in the central part of the Tj
rotor, and the container for storing the junction vibrator is Because it is also 9 inches in the
electromagnetic shielding effect. (1),-1 o Every 5 r-) It is said that it is preferable to adopt a seal
structure. On the other hand, the composite support is supported by a support, and the node
support of the composite oscillator is forcibly made circular by the cylindrical support so that the
m combined vibration oscillator is vibrated in the bending mode. In order to efficiently produce
the work energy due to the bending vibration [41], it is considered preferable to mount a
compound oscillator on a substrate at a time Ql'l. To achieve one goal, vc is to be sealed using the
existing base and case, and it is considered as good as M. 9 ?. An i-wave beater configured in
this way is shown in FIG. As shown in FIG. 1, the self vibration 1-. 2 is an H-electric high morph

processing. 1! The case 7 is fixed together with the ring material 9. In such a conventional
ultrasonic transducer, since the mesh window member 8 is attached to the case 7 by drawing
processing, the production cost is greatly increased by its imprinting and passing, and plating is
also performed. Since the bending mode of the vibrator is used, there is also a drawback that
only narrow band pass characteristics (FIG. 4 (aL (see bl)) can be obtained. The present invention
is E, which is the conventional lack of the problem described above. An object of the present
invention is to provide an ultrasonic transducer in which wide band pass characteristics are
exhibited and attachment of a reticulated window member is very easy, and the purport to that
