    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 motor casing comprises a first casing member (2) and a second casing member (3) which are separated in a direction of the rotational shaft of a motor, the first and second casing members are coupled by coupling members (4), a stator (6) of the motor is held and fixed within the casing by the first casing member and the second casing member, and the coupling portions between the first casing member and the second casing member are positioned inside and also deep into the first casing member. A method for producing a motor casing is such that when it is assumed that a length of the stator (6) held is L1 and a length from an engaging portion of the coupling member (4) with the first casing member to an engaging portion of the coupling member (4) with the second casing member is L2, a strength classification of the required coupling member is determined in advance by converting it into a ratio of L1 and L2.
