Glass Work Patents (Class 451/412)
  • Patent number: 9758311
    Abstract: A method and device useful for material removal from large plate-shaped materials, for example machining and polishing of glass and stone. The invention includes a workstation having arrays of roller and suction cups which are selectively used to transport and secure a plate positioned in the workstation. An imaging device collects data on a true position of the plate in the workstation and compares the real position to a design or ideal position to determine a difference of position. An electronic control system calculates the difference and modifies the processing program to adjust for the difference eliminating the need to further reposition the plate to the ideal design position for processing.

  • Patent number: 8585467
    Abstract: The present invention is directed to an apparatus for grinding or polishing at least one edge of a glass substrate. The apparatus includes a grinding unit configured to remove a predetermined amount of material from the edge when in an aligned position. The grinding unit applies a predetermined force normal to the edge. An air bearing slide system is coupled to the grinding unit. The air bearing slide system is configured to slide along a predetermined axis on a thin film of pressurized air that provides a zero friction load bearing interface. A linear actuation motor is coupled to the air bearing slide system. The linear actuation motor is configured to control the movement of the air bearing slide system such that the grinding unit is moved from a non-aligned position to the aligned position.

  • Patent number: 6629877
    Abstract: Improved accuracy of grinding glass pieces for use in stained glass art and the like. The pattern of the final outer boundary of each piece of glass is traced onto frosted mylar tracing paper to create a mask. The mask is then cut to the traced pattern and is adhered to a piece of untrimmed glass of area greater than that of the mask, using water resistant adhesive. The outline of the pattern is rendered opaque, for example by an ink marker. Thus prepared, the untrimmed glass is abraded on a powered abrading machine having a flat, horizontal work table, a rotatable abrading element disposed to engage a workpiece supported on the work table, and lamps operating at low voltage arranged to back light the workpiece from therebelow. The untrimmed workpiece exhibits a brightly illuminated zone extending outside the opaque zone of the mask, thus emphasizing glass to be eroded. The workpiece is urged against the rotating abrading element until the illuminated zone is eliminated.

  • Patent number: 6514122
    Abstract: A product pattern and a test pattern for managing a focus offset value are patterned onto a product wafer by means of exposure, and is patterned onto the product wafer by means of exposure. The exposed product wafer is developed. A measurement section measures the dimension of the test pattern patterned on the product wafer. On the basis of the thus-measured dimension of the test pattern, the focus off set value set in a system for manufacturing a semiconductor device is computed by a computation section. The focus offset value set in a projection optical system of the system for manufacturing a semiconductor device is adjusted by means of an adjustment section so as to become identical with the computed focus offset value.
