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.

Abstract: A cutting apparatus jets, at a high pressure, water containing abrasive grains to cut a workpiece along cutting lines extending in intersecting directions. The cutting apparatus includes: a fixing table fixing the workpiece; groove portions provided in the fixing table at respective positions below the cutting lines; protruded portions provided in regions of the fixing table other than regions where the groove portions are provided, in a manner that the workpiece contacts the protruded portions; support portions provided to connect the protruded portions substantially in parallel with cutting lines extending the Y direction along the groove portions; a frame portion provided to connect the support portions to each other in at least a part of an outer periphery of the fixing table; and protection members attachably and detachably provided to cover the support portions.

Abstract: Disclosed is a grinding table apparatus for a liquid crystal display panel and a grinder using the adapt to various sizes of unit liquid crystal display panels for grinding edges of the corresponding liquid crystal display panel by adjusting a variable moving distance of the grinding tables instead of replacing the previous grinding table. The present invention includes at least two grinding tables displaced in a direction making the grinding tables get farther from or closer to each other to adapt to the size of the unit liquid crystal display panel to grind edges of the unit liquid crystal display panel.

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.

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.
