ULTRASONIC TRANSMITTING AND RECEIVING ELEMENT

摘要

PURPOSE:To stabilize the signal characteristics, even if the constant of the physical property of an adhesive as well as the mechanical shape of the same is changed due to the change in temperature, by making the thickness of an oscillatory diaphragm one half of the wavelength and the thickness of an adhesive, which is used an ultrasonic converting element and the diaphragm, substantially a quarter of the wavelength.
