    • A positioning apparatus for positioning a test head for testing electronic components is provided. The positioning apparatus includes an outer cylinder and a support coupled to the outer cylinder for supporting the test head. The positioning apparatus also includes a piston arranged within said outer cylinder such that the piston and the outer cylinder define a fluid compartment within the outer cylinder. The positioning apparatus also includes a pressure regulator for maintaining a pressure within the fluid compartment such that the test head may be suspended in a substantially weightless position, the substantially weightless position being adjustable in a vertical direction. The positioning apparatus also includes a lifting device for raising and lowering the outer cylinder. The lifting device includes a threaded drive mechanism coupled to the piston. The positioning apparatus also includes a drive apparatus for operating the threaded drive mechanism to move the test head to a predetermined position.
    • 提供了一种用于定位用于测试电子部件的测试头的定位装置。 定位装置包括外筒和联接到外筒的支撑件,用于支撑测试头。 定位装置还包括设置在所述外筒内的活塞,使得活塞和外筒在外筒内限定流体隔室。 定位装置还包括用于保持流体隔室内的压力的压力调节器,使得测试头可以悬挂在基本上无重量的位置,基本上无重量的位置可在垂直方向上调节。 定位装置还包括用于升高和降低外筒的提升装置。 提升装置包括联接到活塞的螺纹驱动机构。 定位装置还包括用于操作螺纹驱动机构以将测试头移动到预定位置的驱动装置。

    • A method of synchronous deletion of managed files in a file system includes receiving a destroy event for a file to be deleted from the file system, the destroy event being generated upon request to destroy a file or corresponding objects of the files system; processing the received destroy event. Processing the destroy event includes determining if hierarchical storage management of the file system is initiated, and if initiated, continuing processing of the received destroy event; blocking threads indefinitely for an event storm during processing of the received destroy event; determining if the file to be deleted is being premigrated, migrated or is being recalled; aborting migration of the file based on the determination of migration and recall; and deleting the file and server objects corresponding to the file from the file system, where initiation of file deletion and server object deletion are synchronous.
    • 在文件系统中同步删除被管理文件的方法包括从文件系统接收要删除的文件的销毁事件,销毁事件是根据要求销毁文件或文件系统的对应对象而产生的; 处理收到的销毁事件。 处理破坏事件包括确定是否启动文件系统的分层存储管理,并且如果启动,则继续处理所接收的销毁事件; 在处理接收到的破坏事件期间无限期阻止线程发生事件风暴; 确定要删除的文件是否被预先迁移,迁移或被召回; 根据迁移和召回的决定中止档案的移交; 并从文件系统中删除与文件相对应的文件和服务器对象,其中文件删除和服务器对象删除的启动是同步的。

    • In a silencer (1) for a flow passage (2) of a turbomachine, in particular of a power plant, a plurality of walls (2) are arranged in the flow passage (3), extend parallel to a gas flow (4) directed in the flow passage (3), and are spaced apart transversely to the direction of the gas flow (4). The walls (2) are designed so as to absorb airborne noise. In order to reduce the vibration tendency of the walls (2), at least one of these walls (2) is provided with at least one connecting passage (9) which passes completely through the wall (2) transversely to the direction of flow.
    • 在用于涡轮机(特别是发电厂)的流道(2)的消音器(1)中,在流动通道(3)中布置多个壁(2),平行于气流(4)延伸, 引导在流动通道(3)中,并且横向于气流(4)的方向间隔开。 墙壁(2)设计成吸收空气中的噪音。 为了减少壁(2)的振动倾向,这些壁(2)中的至少一个设置有至少一个横向于流动方向穿过壁(2)的连接通道(9)。
