To reduce the driving power of SAW motors, an energy circulation driving method has been proposed and demonstrated. For the energy circulation drive, forward scattering beneath a silicon slider was found to be a problem, due to phase shift relationships. To investigate what phenomena mainly affect the phase shift, several cases of numerical simulation were(More)
In recent years, using phase variable filter, measurement method to analyze spectral property of the atmosphere component or the blood is studied. Then, the value of the interferogram fluctuates by the influence of the disturbance, therefore in this case where the correct spectral characteristics cannot be acquired. In this paper, our control method(More)
