DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tow transducer
for underwater acoustic waves. As shown in FIG. 1, the conventional towing tow / speaker has at
least one ultrasonic transducer 1 and a plurality of x-fees 92! :, A plurality of tension members 3
are accommodated in the flexible cylinder 4 and both ends of the flexible cylinder are fixed by
the band 6 through the terminal plug 5 and the inside is likely to be liquid 7-1 / -7. In the figure,
8 indicates a lead wire. Therefore, in the prior art, when the use environment is low temperature,
the flexibility is simply lost and the elongation rate is reduced. For this reason, when towing or
winding on a drum, force is applied directly to the flexible tube without force on the tension
member, and the flexible tube is enclosed in the band from which the flexible tube is fixed while
being detached. Liquid has the disadvantage of flowing out. Furthermore, it has the disadvantage
that the towing noise is significantly increased because the tow is hardened. The present
invention has a mechanical reliability which eliminates the above-mentioned drawbacks, and
hence acoustically low noise, by incorporating the heater into the towing transducer 10 and
thereby curing the towing transducer by use at low temperature. To provide a tow transducer.
Next, the embodiment of the present invention will be described with reference to the section 15.
FIG. 2 is a side cross-sectional view of the towed transducer of the present invention, and FIG. 3N
shows an enlarged view of a heater attachment portion of the towed transducer of the present
invention. In the present invention, the heat of the heater 9 attached to the silane member 3 by
the clamp 10 warms the flexible cylinder 4 evenly to 20-2 =-through the filling liquid 7.

Therefore, the flexible cylinder 4 has constant flexibility regardless of the ambient temperature,
and the flexible cylinder 4 is flexible and easy to stretch when it is towed or wound on a drum.
Therefore, when the flexible cylinder 4 is detached from the band 6 in which the flexible cylinder
4 is fixed by the force acting on the dent member 3, it will disappear. Further, the lead wire 8 of
the ultrasonic wave work piece 1 also has an effect of having a certain degree of flexibility, and
the soldering portion of the transducer 70 is not broken. Furthermore, the effect of significantly
reducing towing noise at the time of towing is generated. (1) The invention can be used without
the influence of surrounding temperature 7L by incorporating a heater, because the underwater
sound wave towing transducer which has had problems in use at low time as described above,
can be used reliably. The effect is to increase the acoustic ?
