    • An auxiliary tool for holding a rotatable fastener in engaged relation with a driving tool until the fastener can be started into the work is versatile and can be used with many different kinds of driving tools. In use, the present tool is secured magnetically to a ferrous metal portion of the driving tool. Spring rods on the tool can be separated and engaged with a fastener to hold the fastener therebetween and in engagement with the driving portion of the driving tool. Once the fastener is well started into the work, the present tool can be quickly and easily removed to permit the driving tool to be used alone.
    • 用于保持与驱动工具啮合的可旋转紧固件的辅助工具,直到紧固件可以启动进入工件为止,并且可以与许多不同种类的驱动工具一起使用。 在使用中,本工具被磁力地固定到驱动工具的黑色金属部分。 工具上的弹簧杆可以与紧固件分离并接合,以将紧固件保持在其间并与驱动工具的驱动部分接合。 一旦紧固件很好地开始工作,就可以快速方便地拆卸当前的工具,以便单独使用驱动工具。

    • A tool attachment for holding a fastener to a driver therefor comprises a magnetic holding assembly to which are attached spring fingers for grasping a fastener. The construction of the magnetic holding assembly provides for attachment of the device to elongated shafts of various shapes and sizes. The magnetic holding assembly is particularly characterized by an elongated, centrally-disposed pole piece which extends in the same direction as the axis of rotation of the shaft of the driver tool, when the attachment is in place. Magnets are attached to opposite sides of the pole piece in like-pole to like-pole relation, and the holding force so provided is quite high.
    • 用于将紧固件固定到其驱动器上的工具附件包括一个磁性保持组件,弹簧夹连接到该保持组件上用于抓紧紧固件。 磁性保持组件的结构提供了将装置连接到各种形状和尺寸的细长轴上。 磁性保持组件的特征在于,当附件就位时,细长的中心设置的极靴在与驱动器工具的轴的旋转轴线相同的方向上延伸。 磁铁以极 - 极相关连接在极片的相对侧,并且所提供的保持力相当高。

    • A susceptor for heating a plurality of semiconductor wafers, as by rf induction, comprises a hollow truncated pyramid of conventional graphite. The walls of the pyramid are planar except for ledges extending from the outer surfaces of the walls for supporting the wafers. A heat shield of pyrolytic graphite is fixed to the inner surface of the walls, directly behind each of the supported wafers. The heat shield has an area substantially coextensive and in alignment with the area of the wafer. The heat shields are anisotropic and are disposed with their low heat conducting directions extending in directions transversely to the surfaces of the walls so that the portions of the walls sandwiched between the wafers and the heat shields get hotter than the remaining portions of the walls.
    • 如通过射频感应加热多个半导体晶片的感受体包括常规石墨的中空截顶棱锥。 金字塔的壁是平面的,除了从壁的外表面延伸的凸起以支撑晶片。 热解石墨的隔热板固定在壁的内表面上,直接在每个支撑的晶片的后面。 隔热罩具有基本上共同延伸并且与晶片的区域对准的区域。 隔热罩是各向异性的,并且它们的低导热方向设置在横向于壁的表面的方向上延伸,使得夹在晶片和隔热罩之间的壁的部分比壁的其余部分变得更热。
