    Abstract: PROBLEM TO BE SOLVED: To make a micro-actuator to function sufficiently by connecting the micro-actuator to a first surface of a suspension plate so that an R/W converter is projected from a second surface opposite to the first surface of the suspension plate. SOLUTION: A assembly body to be finally assembled is provided with a gimbal 8, the R/W converter and a die 25. The gimbal 8 (forming a thin layer of a suspension) is provided with a first surface 43 facing to the die 25 and a second surface 44 opposite to this surface, and the R/W converter 6 is projected from the second surface 44. A central circular hole 41 provided on the gimbal 8 has a diameter sufficient to allow the R/W converter 6 beforehand stuck to a rotor to passes through. An adhesive material member 42 is arranged between a member 12 to be suspended and the R/W converter 6. A strip 40 is stuck to the first surface 43 of the gimbal 8, and the die 25 is connected solidly with the R/W converter 6.

    Abstract: PROBLEM TO BE SOLVED: To prevent a microactuator from external dust by providing an actuator element being a different body and a transmission structure to be arranged between the actuator element and a motor element and allowing the transmission structure to transmit the motion of the motor element to a motion corresponding to the actuator element to prevent damage and static electric interference. SOLUTION: A microactuator 30 is integrated with the die 31 firmly fixed to gymbals. The microactuator 30 is provided with a motor element 32, an actuator element 34 which is separated from the motor element 32 and also to which R/W transducers 6 are firmly fixed and a transmission structure 36 which is arranged between the motor element 32 and the actuator element 34. The transmission structure 36 transmits the rotational motion of the motor element 32 to the actuator element 34 and the R/W transducers 6 fixed to the element 34. The motor element 32 is provided with the stator 38 of an inner side which is integrated with the die 31 and the rotor 40 of an outer side. The rotor 40 is connected to the actuator element 34 with the transmission structure 36.

    Abstract: A detection, structure (1) for a z-axis resonant accelerometer (24) is provided with an inertial mass (2) anchored to a substrate (20) by means of elastic anchorage elements (6) so as to be suspended above the substrate (20) and perform an inertial movement of rotation about a first axis of rotation (A) belonging to a plane (xy) of main extension of the inertial mass (2), in response to an external acceleration (az) acting along a vertical axis (z) transverse with respect to the plane (xy); and a first resonator element (10a) and a second resonator element (10b), which are mechanically coupled to the inertial mass (2) by respective elastic supporting elements (16), which enable a movement of rotation about a second axis of rotation (B) and a third axis of rotation (C), in a resonance condition. In particular, the second axis of rotation (B) and the third axis of rotation (C) are parallel to one another, and are moreover parallel to the first axis of rotation (A) of the inertial mass (2).
