The ultrasonic horn of 来 is an enlarged figure of 漏 next to 部, 寮 寮 妬 向 寮 寮 寮 v v v 1 v v 部The stutter 1 and the wave source d are housed and mounted in the throat a of the horn C, which has a substantially elliptical distortion, and when it is in the finger in the long direction of the aperture 1-1 of the horn C, That is, the relationship between the line segment direction lRO sound pressure ratio and the above one degree that crosses at an angle of one degree in the long axis direction of the diameter of the horn at the throat a of the horn with respect to the central axis 12 of the horn C 161 (Fig. 161 PM) (大 き く, the absolute value of β degree is smaller than the constant value and the sound pEEh becomes smaller if the absolute value of the degree is larger than the above constant value) Ho / C (Ie, the angle axis of the minor axis of the horn in the throat a of the horn C with respect to the central axis of the horn C). If the relationship between the sound pressure Hv in the direction of the intersecting line and the biarch β degree) e) and the absolute value of 1st-fourth of + + r: <+ β 02-05-2019 1 degree is below a certain value, then the pressure is ˜ Even if the absolute value of β degree is larger than the above-mentioned fixed value, the sound pressure Hv greatly increases and decreases with the increase of the absolute value of β♀, and the directivity characteristic in the minor axis direction of the aperture of horn C is disturbed. The present invention eliminates the prior art defects such as E bow, and the embodiment of the present invention will now be described with reference to the drawings.泗 る 楕 円 し て ホ ー ン ホ ー ン ホ ー ン ホ ー ン 4 4 444444一対一対一対一対一対一対一対一対一対一対一対一対一対一対一対 一対一対一対一対一対一対一対一対一対一対一対一対一対一対一対一対一対 一 対. The piezoelectric crystal piece to be applied resonates with the high i-wave voltage, and generates an ultrasonic wave by bullet action. The ultrasound source 4 is disposed in the throat portion 2 of the horn l. 6 is a plate having a substantially elliptical hole 6 at its center and is provided in the throat portion 2 of the horn 1 in front of the Mi sound EndPage: 1 'temporary source 4 and the major axis direction of the hole 6 is the diameter of the horn It is intended to be a father in the longitudinal direction. The present invention has a configuration like the upper side, and the finger fBJ% characteristic of the long axis direction of the horn 1 (in other words, the throat portion 2FC of Bourneyu with respect to the central axis of the horn l Measure the sound pressure Hh of the line segment direction crossing v 'q 7 z and the above-mentioned base 7)) ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・ ・Sound pressure blood is large ・ If the absolute value of horse a is more than the above-mentioned fixed value, sound pressure blood is small.

If the absolute value of β is less than or equal to a single-foot value, as shown in 1 in FIG. 6, the sound 1 king H is large, and the absolute value of K is Sound to value more capital pressure Hv18 are those of small sheets, short ball direction custom for oriented disturbance of diameter of the horn 1 is reduced. According to the present invention, the ultrasonic wave source 4 is disposed in the throat 2 of the horn 1 whose diameter is gradually increased as it goes from the throat 2 to the opening 3 and the diameter is substantially elliptical. 43, a plate 5 having a substantially elliptical hole 6 at its center! -#E generation is provided in the throat portion 2 of the horn 1 in the front of item 4 and is formed by straightening the long field direction of the hole 6 in the long axis direction of the diameter of the horn l There is an effect that the directivity characteristic of the flit diagram is not disturbed as a result of the measurement. 4. Brief description of the drawings FIG. 1 shows a conventional sum sound wave horn, FIG. 1I is a cross-sectional view, the first F5A port is a cross-sectional view at X-X line above, 11th threshold pi, It is an l-I directional characteristic figure. FIGS. 2 to 6 show an embodiment of the present invention. FIG. 82 shows a cross-sectional view taken along line Y-Y of FIG. 3 and FIG. 02-05-2019 2 The cross sectional view of FIG. 6 and FIG. 6 and FIG. 6 are directivity characteristic views. 1 is a bone, 2 is a throat, 3 is a port opening, 4 is an acoustic wave emitting source, 5 is a plate, and 6 is a hole. 1st (i) (b) (c) (c) (c) $ 2 End EndPage: 26 Inventors other than the above, patent applicants or agents ノ ウ ノ ウ 氏 名 光 光 光 光 光 θ 氏 名 氏 名 橋 橋 (2 ) Patent applicant (3) Agent address Osaka Prefecture Kadoma City Oji Kadoshin Address 1048 Matsushita Electric Works Co., Ltd.
