The suspension mechanism based on NFAL (near-field acoustic levitation) is fundamentally different from that in standing wave levitation. The proposed linear noncontact type actuator can levitate and carry the object along the direction of traveling wave in the planar plate, which produces the high intensity acoustic field. Moreover the object is suspended at the height only between tens and hundreds...
A novel Ultrasonic/sonic Driller/Corer (USDC) has been developed for deep space exploration. This low axial load is required and few impact forces are produced for the USDC to sample rocks, which results in the important advantage of low energy dissipation. Based on inverse piezoelectric effect, the ultrasonic vibration is induced for the transducer of the USDC. The ultrasonic/sonic vibration energy...
