alone at an extremely high sound pressure of 130 kHz to 132 dB, 17 kHz only, 18 kHz only, 19
kHz only, or 17 kHz. A combination of 25 kHz, a combination of 18 kHz and 24 kHz, a
combination of 19 kHz and 23 kHz, or a combination of a plurality of them (2 to 3 are generally
optimal) is used.
This transducer comprises a speaker using a vibrating element made of ceramics or the like.
Then, by performing random transmission with the plurality of transducers, a synthetic wave (4
kHz to 42 kHz) can be obtained and at the same time a standing wave occurs, and a sound
pressure change of addition or subtraction can be made. Further, on the sound pressure surface,
it is possible to output a sound pressure of maximum sound pressure 136 dB to 138 dB.
[0016]
And the random transmission of the transducers is performed by changing the transmission time
of each transducer. Therefore, in order to change this transmission time, the 24-hour timer is set
by the 24-hour timer system, and the on / off operation control of the ultrasonic wave
transmission device is performed.

[0020]
Next, three specific examples of the systematized installation example of the ultrasonic wave
transmission apparatus of the present invention will be described as follows.
[0021]
First, with reference to FIG. 3, an example of installation for a region to be protected which
prevents entry of a rat will be described.
As shown in FIG. 3, an ultrasonic wave transmission device is installed so as to surround a
specific area.
[0022]
Then, based on FIG. 4, the example of installation which prevents the penetration of the rat inside
is demonstrated.
As shown in FIG. 4, by installing in the part used as the channel | path of the exterior and an
interior, the penetration to the inside is prevented.
[0023]
In addition, based on FIG. 5, the ultrasonic transmission apparatus is installed to fill one area with
the transmission direction of the ultrasonic transmission in the same direction, including
capturing the rat.
[0024]
This prevents the rat from infiltrating the area, and by driving the rat in the direction of
transmission of the ultrasonic waves, it is possible to capture by setting up an adhesive trap etc.

in that part. is there.
[0025]
It is as follows when the result of the repelling effect test by the ultrasonic wave transmitting
apparatus for repellents of the above is described.
[0026]
1, test method Make an apparatus as shown in Figure 2, release rat rats (150g, male) captured in
a building in Tokyo, into the test apparatus, feed bottle and feed (parts a and b in Figure 2 (Japan
A Claire rat feed CE-2) was placed for free eating.
Furthermore, a passing cognition counter was set near the entrance of parts a and b, and the
number of passes of the rat was measured.
In order to make the rat accustomed to the test apparatus, it was bred without emitting
ultrasonic waves for 2 weeks.
After 2 weeks, the behavior and the amount of eating were observed when an ultrasonic wave
was transmitted to the part a only or b only at 24 hours and an ultrasonic wave was transmitted
to the b part only at night for 12 hours.
The ultrasonic transmitter was installed at a height of 2 meters at each part of ab and covered
with a blocker around it.
The ultrasonic wave used was 19 kHz and the sound pressure used the transmission device of
135 devel or more.
[0027]
2. Test results and considerations a) a, b both without ultrasonic wave transmission (Table 1)
03-05-2019

observation period 14 days The number of times to a, b is a total of 2422 times, 1229 times into
the part of a, b There were 1193 times for the part. The number of times per day was a
maximum of 221 times in the a part, and an average of 87.8 times in the minimum 56 times. On
the other hand, in the portion b, ab deviation was not observed at a maximum of 207 times and a
minimum of 22 times and an average of 85.2 times. However, a large difference was observed in
food consumption ab and b was barely eaten. The average daily food intake was around 10 g.
[0028]
(Table 1)
[0029]
b) 24 hours continuous transmission a Partial transmission: A total of 966 times have been made
to the a and b parts during the test period of 8 days, of which a total of 108 times have been
made to the a part where ultrasonic waves are being transmitted. The average was 13.5 times at
a maximum of 19 times a minimum of 2 times a day.
On the other hand, a clear difference was observed in a total of 858 times for the portion b
where no ultrasound was transmitted and a mean of 107.3 times at a maximum of 313 times a
day and a minimum of 27 times a day. Also, when looking at the amount of food consumed, the
food in the part a where ultrasonic waves were transmitted was hardly eaten. Furthermore, the
amount of food consumption decreases, and the average is around 6.75 g, and it is presumed
that considerable stress is applied (Table 2).
[0030]
(Table 2)
[0031]
b At the time of partial transmission: During the test period of 8 days, the number of times
performed for the portions a and b was 1,356 times in total, of which only 64 times for the
portion b where ultrasonic waves are transmitted, up to 17 at one day The minimum was three
times.
03-05-2019

On the other hand, 1292 times were sent to the part of a which was not transmitted, and it was
an average of 161.5 times at a maximum of 356 times a day and a minimum of 41 times a day.
Also, when looking at the amount of food intake, the test start date is a minimal amount, but it is
eaten at the b part that has been transmitted, but from the next day there is almost no eating at
the b part there were. Furthermore, the amount consumed was also the same result (Table 3).
[0032]
(Table 3)
[0033]
c) 12 hours at night b Partial ultrasound transmission (Table 4) The test was conducted for 7
days, and a total of 229 times was passed to a part in daytime while it was 91 times to b part in
the daytime. Even though it did not send it, a bias was observed.
This result is quite different from the result without transmission. That is, in the nontransmission test, a and b were almost the same number of passes. As a cause of this, the result
of the non-transmission test is the number of times of passage in one day, and it is considered
that the measurement is not performed day by night. Moreover, although the place to eat eats a
lot at a part in the test by no transmission, the difference in the amount of eating by the place
was not recognized this time.
[0034]
(Table 4)
[0035]
On the other hand, in the nighttime result, it passed a total of 563 times at a non-transmission
site a, but only 99 passes at a transmission site b.
Moreover, the amount of eating was also eaten at a part of no transmission. Moreover, the
amount eaten per day was an average of 7.5 g.

[0036]
From the above results, it was recognized from the present results that the anti-insulting
ultrasonic transmitter has a repellent effect on rats.
[0037]
According to the present invention, the following effects can be obtained based on the above
configuration.
(1) Since it is not necessary to adopt an advanced control system, it can be provided at low cost.
(2) Of course, it is possible to transmit various synthetic waves at random, astounding rats, so
that the effect of prevention of habituation (learning) can be obtained. (3) Using a plurality of
transducers, on / off control can be easily performed by the timer and various sensor signals. (4)
The repellent action of rats in a specific area can be ensured.
