The printer includes a frame that supports a cylindrical member and at least one printhead such that the first printhead is positioned to eject material onto an outer surface of the cylindrical member. The frame is movable between a first position that rotatably supports the cylindrical member and a second position that enables transfer of the cylindrical member to and from the frame. A controller operates the printhead to eject material onto the rotating cylindrical member to form the object. The controller interpolates a periodic signal generated from a position encoder to adjust the operation of the printhead based on the rotational position and velocity of the cylindrical member. The controller operates a driver to move the frame to the second position to enable removal of the cylindrical member from the printer.

    Abstract: A pattern formed on a substrate includes first and second sub-patterns positioned adjacent one another and having respective first and second periodicities. The pattern is observed to obtain a combined signal which includes a beat component having a third periodicity at a frequency lower than that of the first and second periodicities. A measurement of performance of the lithographic process is determined by reference to a phase of the beat component. Depending how the sub-patterns are formed, the performance parameter might be critical dimension (CD) or overlay, for example. For CD measurement, one of the sub-patterns may comprise marks each having of a portion sub-divided by product-like features. The measurement can be made using an existing alignment sensor of a lithographic apparatus. Sensitivity and accuracy of the measurement can be adjusted by selection of the first and second periodicities, and hence the third periodicity.

  • Publication number: 20120107437
    Abstract: A positioning control ejection mechanism includes an ejection motor, an ejection rod, a position confirm switch, and an upper limit switch. The ejection rod is slidably driven with the ejection motor. The position confirm switch is assembled to the ejection motor and is positioned along an ejection direction of the ejection rod. The position confirm switch is configured for sensing when the ejection rod is aligned with a pre-ejection product. The upper limit switch is assembled to the ejection motor and is positioned along an ejection direction of the ejection rod away from the ejection motor end, preventing the ejection rod from being over ejected.

  • Publication number: 20120070527
    Abstract: A level adjustment device includes a main body, four shaft seats, two adjusting elements, two actuating gears, and a supporting plate. The main body has a side surface and an upper surface connected to the side surface. The main body defines two slots in the side surface. Each two shaft seats are positioned at two opposite sides of a corresponding one of the slots and extend outwards from the side surface. Each of the adjusting elements includes a toothed portion and a supporting portion, the toothed portion movably received in the slot and the supporting portion protruding out of the upper surface. Each of two actuating gears is rotatably sleeved between two corresponding shaft seats and meshes with the toothed portion. The supporting plate is supported on the two adjustment elements above the upper surface.

  • Patent number: 8097539
    Abstract: A pattern is formed on a mask substrate. Positional deviation information between an actual position of the pattern formed on the mask substrate and a design position decided at the time of designing the pattern is calculated. A heterogeneous layer of which a volume expands more greatly than that of surrounding mask substrate region is formed in a predetermined position within the mask substrate so that volume expansion of the heterogeneous layer according to the positional deviation information is achieved.

  • Patent number: 8092731
    Abstract: The invention relates to a method for producing a thermoplastic plastic film. According to said method, the thermoplastic plastic is melted and transported in an extrusion installation comprising an extruder, an extrusion nozzle with a wide-slot delivery opening and a chill roll, which is fixed to a roll system and then leaves the delivery opening of the extrusion nozzle in the form of a flat melted web. Said melted web is then applied to the chill roll and is cooled. The invention is characterised in that it uses an extrusion installation, in which the distance between the delivery opening of the extrusion nozzle and the surface of the cooled roll does not vary by more than +/?50 ?m during the operating time. The invention also relates to a film of this type and to uses of the latter.

  • Patent number: 8070993
    Abstract: A method of producing a composite component that includes both a structural insert and a plastic casing. According to an exemplary embodiment, the method uses a closed-loop control system and includes the following steps: evaluating the structural insert for various attributes, placing the structural insert in a mold cavity, adjusting the position and/or orientation of the structural insert with respect to the mold cavity based on, among other things, the evaluated attributes, and injecting molten material into the mold cavity so that it at least partially surrounds the structural insert.

  • Patent number: 8038430
    Abstract: A method of coating metal wire with extrudate using an extrusion system. The method includes the steps of advancing the metal wire through an extrusion die of the extrusion system and extruding molten extrudate over the metal wire as the metal wire is advanced through the extrusion die. Image data is generated, using one or several electronic cameras, concurrently with the advancing, and extruding to provide visual feedback indicative of the concentricity or non-concentricity of extrudate surrounding the metal wire as the metal wire exits the extrusion die.
