Patent number: 6540597Abstract: The polishing pad conditioner incorporates a plurality of diamond prisms 12 arranged regularly and protruding towards a surface to be processed, and a conducting bonding member 14 that fixes the diamond prisms into a single body. The conducting bonding member 14 is provided with a conducting metal plate 15 with a plurality of holes 15a for embedding the diamond prisms 12, and a conducting sintered metal 16 that is filled into the spaces between the holes and the diamond prisms and sintered. The conducting bonding member can be dressed electrolytically by passing a flow of conducting liquid 24 through the gap between the member and an electrode placed opposite. Thus, the surface of a polishing pad can be reprocessed (reconditioned) to an appropriate roughness, so the conditioner can continue to operate under even, stable conditions for a very long time, with a rather low manufacturing cost and without contaminating the silicon wafers.Type: GrantFiled: August 22, 2000Date of Patent: April 1, 2003Assignee: RikenInventor: Hitoshi Ohmori

Patent number: 6539642Abstract: A probe head 10 and a laser interferometric displacement meter 20 are provided. The probe head supports a probe 2 that is capable of contacting a workpiece 1, that is free to move in the direction of the workpiece, and drives the probe towards the workpiece. The displacement meter measures the displacement of the probe with a high accuracy without contact. The probe head 10 is also provided with a probe shaft 12 with steps 11a, 11b at intermediate portions thereof and air bearings 14a, 14b that support the probe shaft on each side of the steps. The air bearings have a high stiffness in the radial direction, and the probe shaft is made to float by using compressed air, thus the resistance of the shaft to sliding is reduced. In addition, another compressed air is supplied to the location of the step and produces a driving force in the direction of the workpiece due to the difference of cross sectional areas on each side of the step, that provides a very small load within a predetermined range.Type: GrantFiled: February 27, 2001Date of Patent: April 1, 2003Assignee: RikenInventors: Sei Moriyasu, Yutaka Yamagata, Hitoshi Ohmori, Shinya Morita

Patent number: 6534742Abstract: In order to adjust the oscillation frequency of a sprung balance intended for or fitted to a mechanical timepiece, in a first step a balance spring is manufactured with a greater elastic torque than a reference torque corresponding to the oscillation frequency provided for the sprung balance. Once the sprung balance is assembled, the balance spring is machined by means of a laser beam to reduce its elastic torque until it substantially reaches the reference elastic torque. In particular, the laser machining consists in removing matter in order either to reduce the height of the balance spring in certain regions, or to reduce the thickness of the strip forming said balance spring. This invention allows conventional regulating means, in particular pins associated with an index, to be omitted. This enables working errors of the timepiece as a function of its position, to be avoided.Type: GrantFiled: November 15, 2001Date of Patent: March 18, 2003Assignee: Eta SA Fabriques d'EbauchesInventor: Florian Serex
