  • Patent number: 8531091
    Abstract: A holding device for a piezoelectric vibrator including a support member (11) for separately accommodating a piezoelectric vibrator (1), a first plate spring member (13) which extends from a proximal end fixedly bonded to one side of the support member (11) so as to sandwich opposing sides of the piezoelectric vibrator (1) and is folded back to be fixedly bonded to the piezoelectric vibrator, and a second plate spring member (18) which extends from a proximal end fixedly bonded to another side of the support member (11) so as to sandwich the opposing sides of the piezoelectric vibrator (1) and is folded back to be fixedly bonded to the piezoelectric vibrator. The first plate spring member (13) and the second plate spring member (18) are integrated at portions fixedly bonded to the piezoelectric vibrator (1).

  • Patent number: 7932661
    Abstract: In the invention, each piezoelectric element for a vibrator for an ultrasonic motor has electrode regions for exciting stretching vibration and flexural vibration separately. Thus, the invention provides a vibrator for an ultrasonic motor, in which electrodes are provided for applying voltage to each of the polarized region, and further provides a stack-type piezoelectric vibrator for an ultrasonic motor, consisting of a stack of the said vibrators and having an extraction electrode pattern provided for short circuit with an external electrode. The vibrator of the invention has high controllability, especially in a fine movement region and is useful as a driving source in a positioning device, in which enhanced vibration efficiency can be obtained.

  • Patent number: 7038658
    Abstract: An input device includes a magnet to be worn by a user on one fingertip of either a right hand or a left hand, a first magnetic sensor to be worn by the user on a wrist of either the right hand or the left hand to detect a magnetic field generated by the magnet at a corresponding position, a second magnetic sensor to be worn by the user on the same wrist on which the first magnetic sensor is worn and at a position that is farther from the magnet than the first magnetic sensor and eliminates effects of geomagnetism, and an output unit to output a difference between an output signal from the first magnetic sensor and an output signal from the second magnetic sensor.

  • Patent number: 5511395
    Abstract: A freely rotatable endless belt has a bottom face that is opposed, in the water, to an ultrasonic oscillator. A carbon fiber fabric is transferred from a supply roller to a hot roller while being given tension by means of a torque motor and a constant speed motor connected to the supply roller and the hot roller, respectively. The carbon fiber fabric moves in contact with the bottom face of the endless belt, whereby endless belt rotates in synchronism with the carbon fiber fabric. Two oblique movement correcting belts are so disposed as to be pressed against both side portions of the endless belt while gripping respective selvages of the carbon fiber fabric. Each of the two oblique movement correcting belts is connected to a variable speed motor via a uni-directional clutch that transmits a driving force only in the direction of transferring the carbon fiber fabric.

  • Patent number: 5016451
    Abstract: An apparatus for disintegrating a carbon fiber fabric. The apparatus includes a water vessel containing water, with an ultrasonic wave oscillator immersed in the water and a guide plate for the fabric being located in opposed relation to the oscillator. A conveyor is provided for continuously conveying the carbon fiber fabric along the side of the guide plate facing the oscillator. Sound waves generated by the oscillator function to press the carbon fiber fabric against the guide plate in a manner as to cause the fabric to be disintegrated under the effects of the ultrasonic waves.

  • Patent number: 4986316
    Abstract: A method and apparatus for feeding a weft to weave a carbon fiber fabric. A carbon fiber package is supported rotatably in such a manner that the axis of the shaft thereof is substantially perpendicular to the running direction of the carbon fiber. The package is rotated so as to deliver the carbon fiber of a prescribed length necessary for one shot weaving of the weft. The carbon fiber of the prescribed length is reserved in a reservoir under an adjusted constant tension before shooting the carbon fiber weft of the prescribed length.
