  • Patent number: 11069374
    Abstract: A method of restoring a suspension of a hard disk drive includes detaching a slider, which is mounted on a tongue portion of the suspension via an adhesive, from the suspension, measuring a thickness of the adhesive in a cleaning area of the tongue portion, specifying a first residual area in which the thickness of the adhesive exceeds a threshold value, irradiating a first irradiation area including the first residual area locally with a first laser beam, and irradiating the cleaning area entirely with a second laser beam.
    Type: Grant

  • Patent number: 10183414
    Abstract: A method punches out a damper from a damper material set on a punching stage with use of a hollow punch so that the punched damper is positioned within a hollow inside of the punch while vibrating a member composing the punching stage on which the damper material is set at the high frequency. The damper material includes a viscoelastic body layer and the constraint layer laminated on the viscoelastic body layer and the viscoelastic body layer includes an attaching surface through which the damper material is detachably attached on the liner.

  • Patent number: 9233479
    Abstract: A cutting jig for cutting a plate material positioned on a supporting surface, includes a jig body, a rolling blade rotatably supported with the jig body to roll on and cut the plate material, and paired holding parts rotatably supported with the jig body at respective sides of the rolling blade in a direction along a rotation axis of the rolling blade to roll on and hold adjoining portions of a cut portion of the plate material, each adjoining portion on which a stress acts due to the rolling blade cutting the plate material at the cut portion.

  • Patent number: 8804135
    Abstract: A method of measuring attitude angles of a tongue of a head suspension, the tongue including a fitting face on which a plurality of electrodes are arranged, emits a single collimated laser beam to an area of a fitting face containing at least two of electrodes, detects a reflected beam from the fitting face, extracts electrode reflective components corresponding to the electrodes from the reflected beam, and according to the electrode reflective components, measures the attitude angles of the tongue.
