The horn, the long tapering steel rod at center, couples the ultrasonic transducer in the housing at top to the tool which presses against the workpiece on the worktable at bottom.

In 1998 the negative effects on THD of an insufficiently broad frequency response of the ultrasonic transducers was quantified with computer simulations by using a precompensation scheme based on Berktay's expression.
33.
Using its synthetic quartz crystals, NDK produces crystal-related products such as crystal devices ( e . g . crystal units, crystal oscillators, crystal filters ) and ultrasonic transducers for medical use.
34.
When the UIT tool, made up of the ultrasonic transducer, pins and other components, comes into contact with the work piece it acoustically couples with the work piece, creating harmonic resonance.
35.
The sonar guidance system was developed for Mod I and improved for Mod II . It used two ultrasonic transducers to determine distance, location within the halls, and obstructions in its path.
36.
For example, the expanding profile of a laser beam, the beam shape of a radar antenna and the field of view of an ultrasonic transducer can all be analyzed using diffraction equations.
37.
In 1999 Pompei's article discussed how a new prototype transducer met the increased frequency response demands placed on the ultrasonic transducers by the precompensation scheme, which was once again based on Berktay's expression.
38.
The ultrasonic immersion method makes use of a temperature stabilised water bath which has a pair of ultrasonic transducers located on either side of the sample which can be rotated using a stepper motor.
39.
In sonomicrometry, small ultrasonic transducers ( usually referred to as " crystals " ) transmit signals to each other, and the distance between them is accurately determined based on the transit-time of the signals.
40.
Sonoporation is also being studied for use in targeted Gene therapy in vivo, in a medical treatment scenario whereby a patient is given modified DNA, and an ultrasonic transducer might target this modified DNA into specific regions of the patient's body.
