摘要: An apparatus for levitating and transporting an object includes a pair of elongated vibrators, a pair of oscillators and a pair of flection limiting rods. Each oscillator includes a horn and a transducer and corresponds to one of the vibrators. Each transducer vibrates the corresponding vibrator through the corresponding horn to generate sound waves from the vibrator. The object is levitated by radiation pressure of the sound waves. Each flection limiting rod corresponds to one of the vibrators. Each rod contacts the lower surface of the corresponding vibrator at a position where the displacement due to vibration is relatively small and reduces the flection of the vibrator due to the weight of the vibrator and the weight of the transported object.

摘要: It is an subject of the present invention to provide a vibration actuator in which a plurality of rotors can be driven by a single vibration unit.When a composite vibrator (2) is driven to generate a composite vibration combining a plurality of vibrations, a first stator (3) and a second stator (4) vibrate, thereby causing elliptical movements in corner portions (8) and (9) of the first stator (3) and the second stator (4), respectively. As a result, a first rotor (A) abutting onto and pressurized against the corner portion (8) of the first stator (3) and a second rotor (B) abutting onto and pressurized against the corner portion (9) of the second stator (4) are rotated at the same time. Further, in this case, by selecting vibration modes of the plurality of vibrations constituting the composite vibration, the two rotors (A) and (B) can be rotated in the same direction or in opposite directions with respect to each other.

摘要: A bone assessment apparatus for obtaining an assessment value E for a bone 12 with good repeatability by simple calculation using the waveform of a signal derived from received ultrasound which has passed through the bone. A transmitting transducer (20) transmits an ultrasound pulse. A receiving transducer (22) receives the ultrasound pulse which has passed through a test sample (10), and then converts the received ultrasound pulse to a signal. An A/D converter (30) digitizes the signal amplified in a receiving amplifier (28). The digitized signal is inputted to a calculator (32) via a transducer controller (26). The calculator (32) calculates the assessment value E for the bone (12) from characteristic values of the waveform of the signal, such as the half-value width of the first positive portion, which are derived from ultrasonic transmission characteristics of the bone (12).
