摘要： A head suspension has a load beam and a piezoelectric actuator. The piezoelectric actuator has an actuator base connected to a base part of the load beam and a piezoelectric element attached to an opening formed in the actuator base. The piezoelectric actuator displaces a front end of the load beam in a sway direction according to deformation of the piezoelectric element that occurs in response to a voltage applied thereto. The head suspension includes a nonconductive adhesive filled between the piezoelectric element and the opening, to fix the piezoelectric element to the opening and a trap formed on the actuator base outside the opening, to hold the nonconductive adhesive oozing out of the opening and prevent the oozed adhesive from spreading. The trap prevents the oozed adhesive from contaminating the periphery of the opening.

摘要： A head suspension has a base plate including a flange. The flange has a first face attached to the carriage arm and a second face attached to an auxiliary member. A first-face contact is circumferentially formed along an outer circumferential edge of the first face of the flange, so that the first-face contact among parts of the base plate except the boss is most proximal to the carriage arm. A second-face contact is circumferentially formed along an outer circumferential edge of the second face of the flange, so that the second-face contact among parts of the base plate including the boss is most proximal to the auxiliary member. This configuration allows the auxiliary member to be correctly aligned with and attached to the second face of the flange.

摘要： An electrical connecting structure for a piezoelectric element enables wiring to the piezoelectric element to be carried out without deteriorating the productivity and reliability of the piezoelectric element. The electrical connecting structure is formed by facing a common electrode of the piezoelectric element to a terminal that supplies power to the common electrode and by injecting a conductive adhesive into a through hole, which is formed substantially at the center of the piezoelectric element, from an opening of the through hole that is on the opposite side of the common electrode, thereby securing electrical connection between the terminal and the common electrode of the piezoelectric element.

摘要： A processing device is provided with a circuit connected to a first conductive portion and a second conductive portion. An AC voltage source produces an AC waveform voltage obtained by adding a bias voltage to an AC voltage for capacitance measurement. The AC waveform voltage is applied between the first conductive portion and the second conductive portion through the measurement probes. The moment the AC waveform voltage is applied to the circuit with a switch closed, an inrush current flows through the circuit based on a potential difference of the bias voltage. This inrush current causes dielectric breakdown in the conductive resin, thereby securing the continuity of the conductive resin. With the continuity of the conductive resin secured, a capacitance of the piezoelectric body is measured by the AC waveform voltage, and it is determined whether or not the piezoelectric body is normal.

摘要： A head suspension 11 includes a load beam 17 having a base plate 13, a hinge part 15 resiliently supported by the base plate, and a rigid part 14 joined with the hinge part, a reinforcing plate 25 joined with the rigid part at a portion proximal to the hinge part, and a bend 17c on the load beam formed by bending the load beam toward the reinforcing plate along an edge 25a of the reinforcing plate. Only by accurately joining the reinforcing plate with the load beam in a sway direction (a widthwise direction of the head suspension), the load beam is easily and properly bent without torsion to form the bend 17c along the edge of the reinforcing plate that defines a bending strength boundary.
