  • CAPACITIVE TYPE HUMIDITY SENSOR AND MANUFACTURING METHOD THEREOF
    Publication number: 20120057252
    Abstract: A lens drive apparatus includes a lens holder configured to hold a lens body, a translating mechanism having a magnet, a coil, and a yoke and configured to translate the lens holder along the direction of an optical axis, and a base member formed of a resin material and including an insert-molded metal plate member in a state of being partly exposed, in which the part of the metal plate member exposed from the base member has a structure thicker than other parts, and part of the yoke is fixed to the metal plate member exposed from the base member.
    Type: Application

  • Driver using electromechanical energy transducer
    Patent number: 7545086
    Abstract: A driver includes an electromechanical energy transducer deformed by applying and removing voltage, a supporting member having the electromechanical energy transducer joined thereto for transmitting movement of the electromechanical energy transducer resulting from the deformation to the supporting member, and a movable body disposed in an inner peripheral portion of the supporting member. A deformation speed of the electromechanical energy transducer when a state change occurs from a prior-to-deformation state of the electromechanical energy transducer to an after-deformation state of the electromechanical energy transducer differs from a deformation speed of the electromechanical energy transducer when state change occurs from the after-deformation state to the prior-to-the deformation state.
