    • A dual band antenna contains a first radiating conductor plate disposed substantially parallel to a grounding conductor, a power-supplying conductor plate extending downwards from the first radiating conductor plate, a connecting conductor plate for connecting the first radiating conductor plate to the grounding conductor, a second radiating conductor plate provided upright beneath the first radiating conductor plate and having a substantially wedge-shaped, elastically deformable portion, and a synthetic resin adjusting screw threaded to the first radiating conductor plate for depressing the top portion of the second radiating conductor plate downwards. The first and second radiating conductor plates resonate at first and second frequencies respectively (with f2>f1). The gap between the second radiating conductor plate and the first radiating conductor plate can be changed.
    • 双频天线包括基本上平行于接地导体设置的第一辐射导体板,从第一辐射导体板向下延伸的供电导体板,用于将第一辐射导体板连接到接地导体的连接导体板, 第二辐射导体板,其设置在所述第一辐射导体板的正下方,并且具有大致楔形的可弹性变形部分,以及合成树脂调节螺钉,其被拧到所述第一辐射导体板上,用于向下按压所述第二辐射导体板的顶部。 第一和第二辐射导体板分别以第一和第二频率共振(具有f 2 2 1)。 可以改变第二辐射导体板和第一辐射导体板之间的间隙。

    • A machine tool is provided having a spindle mounted for movement in a direction parallel to the spindle axis, the Z direction, and a direction perpendicular to the spindle axis, the X direction. The machine tool includes a machine bed and has means mounted to the machine bed for supporting at least one tool. At least one spindle is rotatably supported on the machine bed and includes a chuck for supporting a workpiece. The machine tool includes means mounting the spindle to the machine bed for movement in the Z direction and for independent movement in the X direction. Accordingly, the workpiece supporting means may be moved proximate to the tool supporting means and the workpiece may be engaged by a tool. The machine tool may further include feeder means for feeding bar stock to the workpiece supporting means so that the bar stock may be engaged by a tool. The machine tool may also include workpiece transfer means for facilitating the transfer of workpieces to and from the workpiece supporting means. A machine tool system embodying the machine tool also forms a part of the invention and includes a plurality of machine beds, each having a spindle and means mounting the spindles to the machine beds for moving the spindles in the Z and X directions. An associated method is also disclosed.
    • 本发明提供一种机床,其具有主轴,所述主轴安装成沿与主轴轴线,Z方向以及与主轴轴线垂直的方向X方向移动。 机床包括机床,并且具有安装到机床上的装置,用于支撑至少一个工具。 至少一个主轴可旋转地支撑在机床上并且包括用于支撑工件的卡盘。 机床包括将主轴安装到机床上用于沿Z方向移动并且在X方向上独立运动的装置。 因此,工件支撑装置可以靠近工具支撑装置移动,并且工件可以由工具接合。 机床还可以包括用于将料斗供给到工件支撑装置的进给装置,使得料斗可以由工具接合。 机床还可以包括工件传送装置,用于便于将工件传送到工件支撑装置和从工件支承装置传送工件。 体现机床的机床系统也形成本发明的一部分,并且包括多个机床,每个机床具有主轴和将主轴安装到机床上的装置,用于在Z和X方向上移动主轴。 还公开了一种相关联的方法。
