摘要： A tangential fan and cutoff assembly for recirculating a lasing gas mixture has blade members, which vary in circumferential position stepwise from end to end, and/or a tapered anode assembly. The number of blade members can be constant or variable between ends. The circumferential position of blade members can shift monotonically or reversibly between ends. Blade members are stiffened by optimally selecting the number and placement of hub members to control the natural vibration frequency of the fan. Methods of forming tangential fans include casting, and machining from a solid block. Monolithic structures can be joined, typically by electron-beam welding. Casting, welding, and machining processes introduce no additional contaminants. Tangential fans produced have mechanical rigidity, accurate tolerances, and low contaminant concentrations. Blade members can be formed into air foil shapes.

摘要： A tangential fan with cutoff assembly for recirculating a lasing gas mixture has blade members, which vary in circumferential position stepwise from end to end, and/or a tapered anode assembly. The number of blade members can be constant or variable between ends. The circumferential positions of blade members can shift monotonically or reversibly between ends. Blade members can be formed into air foil shapes and are stiffened by one or more transverse annular hub members. Processes for making tangential fans include soldering, casting, and machining from a solid block. Monolithic structures can be joined, typically by soldering or electron-beam welding. Casting, welding, and machining processes introduce no additional contaminants. Soldering produces substantially silicon-free assemblies. Tangential fans produced in accordance with the invention have improved mechanical rigidity, accurate tolerances, and low contaminant concentrations.

摘要： A window assembly for a pressurized laser discharge chamber is disclosed and may include a housing that is formed with a recess. The assembly may also include an optic having a first side that is exposed to chamber pressure and an opposed second side, and a compliant member that may be positioned in the recess to space the second side of the optic from the housing under normal chamber operating pressures. For the assembly, the compliant member may be compressible to allow the optic to mechanically abut the assembly housing during a chamber overpressure.

摘要： The operation of a data flow is improved by providing for validation of the consistency of the data flow with the external data files it works with, even in the face of changes in those external data files Metadata is stored regarding the external data files. Because external data files may change, this metadata is used when determining whether the external data files are still compatible with the data flow. In such performing such validation, the metadata tracks what changes in the external data files have occurred, and allows increased flexibility in presenting the user with options or in automatically fixing the data flow to correspond with changes in external data files. When the external data files are not available, the stored metadata can be used to validate the data flow to the last information regarding the external data files. The external metadata can be resynchronized to the data flow or to the external data files to provide updated external metadata for later validation.
摘要翻译： 通过提供数据流与其工作的外部数据文件的一致性的验证来改进数据流的操作，即使面对这些外部数据文件的变化，存储有关外部数据文件的元数据。 因为外部数据文件可能会改变，所以在确定外部数据文件是否仍然与数据流兼容时使用此元数据。 在这种执行这样的验证中，元数据跟踪外部数据文件发生了什么变化，并且允许在向用户呈现选项或者自动修复数据流以对应于外部数据文件的变化的灵活性方面。 当外部数据文件不可用时，可以使用存储的元数据来验证数据流到有关外部数据文件的最新信息。 可以将外部元数据重新同步到数据流或外部数据文件，以提供更新的外部元数据，以供稍后验证。
