Abstract: A surface treatment plant for treating objects, in particular vehicle bodies, has a thin film conversion process in which a ceramic thin film is applied to the objects using a process medium, a subsequent rinsing step in which the objects are rinsed with rinsing medium after the thin film conversion process, and a deionization plant which has a cation exchanger and a downstream anion exchanger and is configured for deionizing the process medium and/or the rinsing medium. For economical operation, the deionization plant is preceded by a preconditioning apparatus which is configured for removing complex anions which are formed and/or present in the thin film conversion process from the process medium and/or the rinsing medium. Furthermore, a corresponding preconditioning apparatus and a treatment process are described.

Abstract: A method for operating a surface treatment installation wherein overspray that occurs in one or more coating booths is taken up by a booth air stream. Booth air laden with overspray is conducted to at least one separating unit in which overspray is separated out. The booth air laden with overspray or the booth air free of overspray is fed a solidifying material on its flow path to at least one separating unit and/or the booth air laden with overspray or the booth air free of overspray is fed a solidifying material in the interior of at least one separating unit and/or overspray that has already been deposited in at least one separating unit is fed a solidifying material and/or the at least one separating unit is fed a solidifying material before the separating unit is functionally fitted in the surface treatment installation, wherein the solidifying material has the effect that a curing process in the overspray is initiated or assisted.

Abstract: In a method and system for production of a printed document with a unique identifier, the data medium for the unique identifier is applied on a recording medium, the data medium being capable of being electronically written without contact so that data are written without contact onto the data medium in the course of a document production event. Data of at least one of a user program, of the printed document, and of the data medium are linked in a file.

Abstract: An apparatus and method for performing a second toner image fixing on a toner image on a carrier material includes a second fixing unit in the carrier material transport path. The second fixing unit is in a burn-in unit that is spaced by a cooling distance from the printer or copier and its toner fixing unit. The first fixing unit of the printer or copier fixes the toner image in a first fixing condition and the second fixing unit fixes the toner image in a second fixing condition. For printers or copiers that perform two sided printing and have front and back side fixing units, the burn-in unit also has front and back side fixing units for fixing the toner image in the second fixing condition. A controller may be provided to reduce the heat energy applied to the first fixing unit in the printer or copier to partially fix the toner image so that the second fixing unit further fixes the toner image.

Abstract: Disclosed is a method for fabricating a contract hole plane in a memory module with an arrangement of memory cells each having a selection transistor. The methods can be utilized during the production of dynamic random access memory (DRAM) modules.

Abstract: A mark configuration for the alignment and/or determination of a relative position of at least two planes in relation to one another in a substrate and/or in layers on a substrate during lithographic exposure, in particular, in the case of a wafer during the production of DRAMs, includes a mark structure, and at least one layer of a definable thickness underneath the mark structure for adjusting the physical position of the mark structure relative to a reference plane in or on the substrate. Also provided is a wafer having such a configuration and a process for providing such a configuration. The invention allows a mark configuration to have mark structures exhibiting good contrast regardless of the design or the process conditions.

Abstract: In order to fabricate a contact hole plane in a memory module with an arrangement of memory cells each having a selection transistor, on a semiconductor substrate with an arrangement of mutually adjacent gate electrode tracks on the semiconductor surface, an insulator layer is formed on the semiconductor surface and a sacrificial layer is subsequently formed on the insulator layer, then material plugs are produced on the sacrificial layer for the purpose of defining contact openings between the mutually adjacent gate electrode tracks, the sacrificial layer is etched to form material plugs with the underlying sacrificial layer blocks, after the production of the vitreous layer with uncovering of the sacrificial layer blocks above the contact openings between the mutually adjacent gate electrode tracks, an essentially planar surface being formed, then the sacrificial layer material is etched out from the vitreous layer and the uncovered insulator material is removed above the contact openings on the semiconduct

Abstract: A mark configuration is provided for the orientation and/or determination of the relative position of a substrate and/or of layers on the substrate during a lithographic exposure, in particular for the case of a wafer during the fabrication of DRAMs. At least one part of a mark is disposed above a patterned background for the purpose of increasing a difference in contrast between the mark and the substrate. A wafer can also be manufactured with such a mark configuration. A method for fabricating the mark configuration is also described. An efficient and simple orientation of layers and/or of the substrate is thus made possible.

Abstract: A printing and/or copying device (10) contains a fixing unit (14, 18) with which the toner image that is transferred is fixed on the support material (28) in a first fixing state. A second fixing unit (50, 52) is then used to fix the image that has already been fixed by the first fixing unit (14, 18) in another, second fixing state according to the desired fixing characteristics. The second fixing unit (50, 52) can be configured in the form of a mechanically and or electrically couplable burn-in station.

Abstract: A pick-up device for products having round portions which can be gripped frictionally, ranging from heavy metal products having bores or round holes to thin-walled drinking glasses having round peripheries, has a cylindrical part which can be positioned radially opposite to the round portion, either by insertion or encirclement, and having a circumferential groove radially facing the portion. A cylindrical elastic elastomer ring is positioned loosely in the groove and has axially extending lip seals slidably engaging the groove's sides. Fluid pressure introduced to the groove behind the ring causes the ring to elastically deform towards and frictionally grip the round portion of the product to be picked up, and by the resiliency of the ring, to release the portion when the pressure is terminated.
