    摘要: A vibration characteristic measuring device is provided with a shaker, including a shaking section which reciprocates along an axis, and a mounting block fastened to a mounting surface of the shaking section. A disk drive suspension is mounted on the mounting block. The mounting block has a facing surface which faces the mounting surface of the shaking section. An adhesive member formed of a resin tape is disposed between the mounting surface and the facing surface of the mounting block. The adhesive member is deformable depending on a gap between the mounting surface and the facing surface. The adhesive member closely contacts both the mounting surface and the facing surface without a gap.

    摘要: A method of testing a fitted state of a pair of piezoelectric elements fitted to form an actuator between a base member and a movable member, the piezoelectric elements in the actuator being arranged side by side in opposite polarity and being electrically connected in parallel with each other, and when a voltage is applied to the piezoelectric elements, minutely moving the movable member relative to the base member in a direction in which the piezoelectric members are arranged side by side. The method detects changes in capacitance of the piezoelectric elements with respect to changes in bias voltage applied to the piezoelectric elements, the bias voltage being changed within a predetermined range, and determines a fitted state of the piezoelectric elements according to a characteristic of the detected capacitance changes. The method correctly and easily determines whether or not the piezoelectric elements are correctly fitted to the actuator.
