METHOD FOR FORMING ACOUSTIC MATCHING LAYER, ACOUSTIC MATCHING LAYER, AND ULTRASONIC SENSOR

摘要

PROBLEM TO BE SOLVED: To obtain an acoustic matching layer which is uniformly distributed without breaking hollow glass beads.;SOLUTION: Hollow glass beads 101a exhibiting low breaking strength are previously broken by the rotation of a paddle 203 provided at a stirrer 201. A shaping mold 301 can be filled with the hollow glass beads 101a uniformly while broken hollow glass beads 101b are removed by forming a gap between the paddle 203 and the stirrer 205 for separating the broken glass beads 101b.;COPYRIGHT: (C)2006,JPO&NCIPI
