Title:
ULTRASONIC WAVE GENERATING DEVICE AND ULTRASONIC WAVE GENERATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/132143
Kind Code:
A1
Abstract:
The present invention provides a new action to an object in a through-hole formed through an ultrasonic wave converging part and a waveguide, by devising the shape of the through-hole. An ultrasonic wave converging part (12) and a waveguide (13) have a through-hole (20) formed through the ultrasonic wave converging part (12) and the waveguide (13) in a front-rear direction. An inner circumferential surface (20A) forming the through-hole (20) has a first inner circumferential surface (21) and a deformation part (23) disposed closer to a leading end side than the first inner circumferential surface (21). The first inner circumferential surface (21) has a shape in which a cross section thereof cut in the front-rear direction extends linearly in the front-rear direction. In the cross section cut in the front-rear direction, the deformation part (23) is at least one of a region on the inner side of the first inner circumferential surface (21) or a region on the outer side of the first inner circumferential surface (21) (in the example shown in FIG. 1, the region on the inner side of the first inner circumferential surface (21)), and is formed across a portion or the entire circumference (in the example shown in FIG. 1, across the entire circumference) of the inner circumferential surface (20A).
