  • Patent number: 6458016
    Abstract: A polishing fluid comprising a distributed organic phase and a continuous aqueous phase. The distributed phase has at least one complexing agent and the aqueous phase has abrasive particles dispersed therein. Reaction products generated during polishing interact with the complexing agent(s) to form organometallic complexes. Further disclosed is a polishing method, a semiconductor device and semiconductor device fabrication method utilizing the polishing fluid.

  • Publication number: 20010036794
    Abstract: There are provided a lens periphery processing method for an eyeglasses lens, a lens periphery processing machine and lens for eyeglass, in which a V shaped portion that fits strongly in a lens frame of eyeglasses frame, can be processed in such a manner that V shaped portion contact with inside of the V shaped groove of the lens frame so that a contact element does not interfere with a holding means for fixing and holding a lens frame, and even if the V shaped groove shape is measured in a state in which the lens frame is tilted, a difference in size due to holding position between the lens frame and a processed eyeglasses lens does not arise.

  • Patent number: 6217420
    Abstract: A grinding or polishing machine comprises a rigid platform on which a workhead spindle and a grinding wheel spindle are located. The grinding wheel spindle is mounted on a sub-assembly which is attached to the platform by means of flexures which permit limited movement of the sub-assembly in a direction generally parallel to the direction in which the wheel has to advance to achieve grinding or polishing of a workpiece mounted on the workhead spindle. The flexures generally inhibit movement of the sub-assembly in all other directions. Two grinding wheels are mounted on the platform, one on each of two sub-assemblies, and each sub-assembly is attached to the platform by flexures as aforesaid. The flexure mounting points are located generally centrally of the machine and are located on either side of and close to the machine centre line.

  • Patent number: 6179700
    Abstract: A mechanism for honing non round cylinder bores includes a tool body rotatable around a nonrotatable cam with a non round peripheral cam surface and a plurality of honing stones carried by supports for generally radial movement in the tool body. In a preferred embodiment, the supports are swing arms pivotally mounted so that the honing stones follow generally radially oriented arcuate paths determined by cam followers carried by the swing arms. A separately controlled expansion actuating rod axially adjusts expansion shoes that wedge outward stone shoes carried by the swing arms to progressively remove stock from the cylinder and to compensate for wear of the honing stones. Assembly with an associated machine adapter supports the honing mechanism and connects with a conventional honing machine to drive and orient the assembly for accurately honing non round cylinder bores.

  • Patent number: 5609512
    Abstract: An apparatus and method for honing, sharpening or grinding a curved peripheral cutting surface of a slicer blade are provided. Included is the use of one of a set of interchangeable cams that generally follows the curved shape of the blade cutting surface, whether same has a constant radius or varying radii. In order to minimize downtime and sanitation operations, the honing is accomplished off-line of the slicer equipment. Preferably, the slicer blade remains perfectly flat during honing, and the movement of one or more honing or grinding wheels is closely controlled so as to provide honed or ground cutting edges which are of substantially uniform width throughout their respective peripheries. Honing is accomplished in accordance with objectively measured sharpness standards by which superior sharpness levels are attained.
