摘要： An apparatus for levitating objects has an elongated diaphragm and a transducer. The diaphragm has a first end portion and a second end portion. The first end portion is fixed to a horn and the second end portion is fixed to a supporting member. The transducer is connected to only the horn. The transducer vibrates the diaphragm and an object is levitated above a surface of the diaphragm by radiation pressure of a sound wave generated from the diaphragm. Therefore, the elongated diaphragm can be vibrated by one transducer in a stable condition with a simple structure.

摘要： A vibrating transducer is coupled to one end of an elongated vibrating plate and a receiving transducer is coupled to the other end of the vibrating plate. Langevin transducers are used for the vibrating and receiving transducers. Each transducer includes a pair of annular piezoelectric elements. The vibrating transducer is connected to an oscillator. A controller controls the oscillator. Detection signals of a voltage sensor, which detects the vibrating state of the receiving side of the vibrating plate, are fed back to the controller. The controller controls the oscillator such that the phase difference between the vibration of the vibrating side and the receiving side is within a predetermined range and that the receiving side is vibrated by amplitude greater than or equal to a predetermined amplitude.

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： A rotor 2 of an ultrasonic motor 1 is pressed to make contact with a pair of supporting parts 11, 12 of a stator 3. Contact surfaces 21, 22 are formed respectively following the shape of an outer circumferential surface 2b of the rotor 2, in the upper portions of the supporting parts 11, 12. Since different level sections 23, 25 are formed in the contact surface 21, and different level sections 24, 25 are also formed in the contact surface 22, the contact distance between the rotor 2 and the stator 3 is limited.

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： In an operating system for a movable body that runs on a guide rail, a communication method is described that establishes communications between the movable body and an operation control unit for controlling running of the movable body. Power lines on which electric power is transmitted are laid on the guide rail. The movable body is runnable upon reception of the electric power from the power lines. The method includes the steps of (a) generating a communication signal in either the movable body or the operation control unit; (b) superimposing the communication signal on electric power to be transmitted on the power lines; (c) receiving the electric power with the superimposed communication signal at the other of the movable body or the operation control unit; and (d) acquiring the communication signal from the received electric power.
