Invention OS thin taa ? ? ? ? ? ? ? ? ? ??!! !! I! As a conversion, jlln 9 Feasibility and
observation in the water underline, and its purpose is to sing and watch its silver sound waves
and glomonic properties. At the same time, using a perforated disk-type piezoelectric ceramic
resonator or a disk-shaped piezoelectric ceramic resonator with a small hole at the center 11 as
an ultrasonic sound wave resonator for water, it is possible to use electricity in the radial
direction # & ? mode In the case of dynamic driving, ultrasonic waves of the transducer are
emitted from the outer peripheral surface of the transducer, and its several fingers are perfectly
circular in the radial direction of the resonator, ideally nondirectional The directivity
characteristics in the plane including the central axis of the resonator (in the plane perpendicular
to the plate surface) produce side lobes in the central axis direction, and the attenuation pole is
10 @@ from the central axis. It is in the ao of ao @. When the plate surface of the resonator is
used horizontally as a sound source in water, the pressure accumulation level tj of the ultrasonic
waves radiated at this attenuation pole angle becomes lower. If radio waves in this direction are
received, a sensitivity drop of at least 10 to 16 dB is observed, and it is considered unreliable due
to the noise level in the sea and the running noise of the receiving vessel. If the thickness of the
vibrator is set so as to avoid the overcharge and side pole and its attenuation pole as much as
possible, improvement of such as holding a busy ultrasonic anti) g3 elbow board holding the ??
? O vibrator is tried Do not make noise, or the size of the vibrator 11), because of the difficulty
of ori in the realization of the O's, 1 @ kC1 ultrasonic vibrator of this kind The telemeter type
underwater 11! ! ! ! When used as a sound source for the vessel, the reflectors and projections
provided to improve the winter travel characteristic winter have an adverse effect on the natural
fall posture in the sea, causing fluctuations in the fall track and moderate fluctuations under the
curtain. There is a ? I [namely, an error P in the ice P position.
This invention is like this! We provide a dumping type underwater observer that solves point IIIa.
Below, the first line of the present invention I 11 #! I will explain along with the 1st floor. In I, 1

the case of measuring 6 depths of sea water temperature 9, water observation! ! When I throw 1

vibrometer T # i adjustment gang Hiro) in the vibration mode is devilishly It is driven busy and
ultrasonic waves are emitted from the other 11 parts into the water. Therefore, the underwater
observation cap IO natural soda shielding degree is previously determined to be a predetermined
t) @, the ultrasonic wave from this 1 m 111 of the underwater observation is received, and the
water depth distribution of the temperature of the seawater can be measured. At this time, a part
of the ultrasonic wave emitted from the outer surface of the ultrasonic transducer 7 is reflected
and broken by the constant plate O edge 11bK, and as a result, it deviates from the letter writing
liquid transducer 7 and is different from the letterpress liquid transducer 7 Pressure distribution

and height of the edge b in f k ? differ depending on the material of the operating station of the
ultrasonic transducer 7 and the material of the constant plate 9. In addition, it is $ 1 or more to
construct a constant ? 9 with ki metal material to increase the reflection and refraction of

declination pole O radiation angle to stop on the side rope is 11 lines from the central axis. In the
above embodiments, ultrasonic transducers T ':: H j! However, the same O effect can be obtained
also in the case of using a two-disc type reciprocator. As described above, according to the thick
groove vK, the fixed plate and the holding plate are formed Wj by providing an edge on the lower
edge of the 11 spread plate, and the air gap is narrowed in the vicinity of the outer mean of the
ultrasonic transducer. From the point of view, it is possible to obtain the excellent effect that it is
possible to improve the directivity characteristic of the article by making the angle of the trial
