The micro processing which possesses bias polarity beam profile control the ultrasonic transducer null which

摘要

The ultrasonic transducer where the capacitance which possesses the control of the high base angle phase by the police box of bias polarity was minutely processed is disclosed. You can obtain the simple ultrasonic probe which possesses the thickness attribute of the slice which is superior as a result of control of this kind of high base angle phase. Furthermore, strict spatial change of phase causes the efficient method of actualizing transmission opening and opening apodeizeishiyon control. Furthermore, the ultrasonic transducer where this kind of capacitance was minutely processed the mechanical lens which has loss necessity do, can actualize the focus focus in the high base angle.
