範囲第１項記載の超音波遅延線。[Claims for Utility Model Registration] (1) The shape of the main surface of the ultrasonic delay medium is a pentagon or hexagon with one corner of a rectangle or two adjacent corners on the short side cut out at an angle of approximately 45 degrees. In an ultrasonic delay line in which an input transducer and an output transducer are attached to one of the notched surfaces, and a damping material for attenuating ultrasonic waves is provided on at least one of the main surfaces, at least one An ultrasonic delay characterized by having an attenuating material at a peripheral portion of the main surface near the cutout surface where the input/output transducer is attached, at a position intermediate between the attachment positions of the input transducer and the output transducer. line. (2) Attenuating material provided at the periphery of the main surface of the ultrasonic delay medium near the cutout surface where the input/output transducer is attached, at a position midway between the attachment positions of the input and output transducers. , the length of the short side of the rectangle provided in the shape of a rectangle on the main surface is shorter than 2 mm, and the length of the long side is determined according to the desired ultrasonic propagation near the position where the damping material is provided. Utility model registration claim No. 1 whose length does not fall within any area on the main surface corresponding to the ultrasonic propagation path other than the ultrasonic propagation path that directly inputs and outputs to the input transducer or output transducer. The ultrasonic delay line according to item 1.
