  • Patent number: 7146863
    Abstract: In a torsion angle measuring method and device for a magnetic-disk suspension, a datum surface of the suspension is fixed to a fixture under pressure, the fixture being provided with a smooth criterion surface having known torsion angles set for the suspension datum surface. A roll angle and a pitch angle of a slider loading surface of the suspension to the datum surface when the suspension is fixed to the fixture are measured.

  • Publication number: 20060113286
    Abstract: A method of cutting a stack structure and the stack structure are disclosed. In the stack structure comprising at least one laser absorbing member and at least one laser transmitting member, a plurality of grooves are formed on the surface of the laser transmitting member which is in contact with the laser absorbing member, which grooves correspond to a plurality off cutting lines. In order to cut this stack structure, a laser beam is emitted on the laser absorbing member along each of the cutting lines, while at the same time gas is injected at the laser irradiated spot.

  • Publication number: 20060076105
    Abstract: A device such as an MEMS device is fabricated by cutting a laminate of a semiconductor substrate and a glass substrate. Grooves are formed in the glass substrate, and the semiconductor substrate and the glass substrate are laminated together such that the groove faces the semiconductor substrate. The laminated substrates are irradiated with a laser along the groove from the side of the glass substrate. In this way, the laminate is cut into elements.

  • Publication number: 20050269731
    Abstract: A method of fabricating an element having a microstructure such as an MEMS device uses a material whose state changes with a temperature change. A sheet-like member having a microstructure on its surface is fixed to a vacuum chuck by an adhesive sheet and the material whose state changes with a temperature change is applied to the surface of the sheet-like member the material is then cooled to solidify it on the surface of the sheet-like member and the sheet-like member is cut 10 into a plurality of elements, while the material is in the solidified state, and the separated elements are then removed from the adhesive sheet.
