METHOD OF MANUFACTURING ACOUSTIC MATCHING MEMBER, ULTRASONIC SENSOR USING THE ACOUSTIC MATCHING MEMBER AS ACOUSTIC MATCHING LAYER, AND FLUID FLOW MEASURING APPARATUS USING ULTRASONIC SENSOR |
摘要 |
PROBLEM TO BE SOLVED: To improve production efficiency by eliminating uneven steps on a side wall surface in an acoustic matching member comprised of a mixture of a hollow sphere and a binding material so as to manufacture an acoustic matching member which is smooth all over the the side wall surface. SOLUTION: In a housing 7 comprising a housing chamber 8 for housing a mixture 16 of a hollow sphere 9 and a binding material 11, the binding material 11 on an interface of the housing chamber 8 is quickly heated and cured from heating of the housing 7 itself by induction heating or the like as a first curing step, the first curing step is implemented and the binding material is then heated and cured in an atmosphere tank as a second curing step, so that the entire front surface of the side wall of an acoustic matching member 17 can be formed as a smooth surface and the acoustic matching member 17 can be equally cured as a whole.
