摘要： A clamping mechanism for locating sheet metal components includes a carrier plate and a clamping jaw swivel-mounted in relation to the carrier plate, the sheet metal components being clamped in contact areas between the carrier plate and the clamping jaw. The carrier plate is bolted to a support element, which is fixed to a base unit. Between the carrier plate and the support element there is an intermediate plate, which is positioned in relation to the carrier plate by a first set of locating pins and in relation to the support element by a second set of locating pins. The use of an intermediate plate with modified orientation of the locating pins may enable the carrier plate together with the component contact areas provided thereon to be displaced in relation to the support element.

摘要： A scattered-ray grid has a carrier with absorption elements arranged thereon in spaced rows which proceed essentially spoke-like relative to a grid center. Except for one or more rows which originate at the grid center, the individual rows of the scattered-ray grid, or of substantially identical grid sectors of the scattered-ray grid each originate from respectively different radii. The origin of each row is situated in an angle section, which is determined on the basis of at least two points lying on a circle, or an arc of circle, with a predetermined radius and which is divided in a predefined ratio for determining the position of the origin. The predetermined radius is incremented in a stepwise manner to define respective origins for all of the rows.

摘要： The specification is directed to a method of operating a machine tool which enables a machining center, a transfer line or a flexible manufacturing system to be rapidly converted from the manufacture of one work piece to the manufacture of another workpiece. This is achieved by mounting all the tools associated with one series of machining steps on a common carrier unit and adapting the carrier unit so that it can be placed quickly in position on the machine tool and automatically centered in a variety of positions so that each of the individual tools can be brought into a desired machining relationship with the workpiece. The tools can comprise both stationary and driven tools and the machine tool is adapted to allow relative movement between the workpiece and the individual tools so as to carry out the desired machining steps. The tools can be preadjusted in their mounts before the carrier unit is placed on the machine tool and are to be stored already mounted on the carrier units to avoid tool losses when not in use. During machinery the tools preferably remain in the mounts but in one embodiment tools can be withdrawn from the mounts and transferred to a machining head. The carrier units are preferably of bell-like form and located on machine tools by means of a pair of mating Hirth rings.
摘要翻译：本说明书涉及一种操作机床的方法，其能够使加工中心，输送线或柔性制造系统从一个工件的制造快速转换为另一个工件的制造。这是通过将与一系列加工步骤相关联的所有工具安装在公共载体单元上并适配载体单元来实现的，使得其可以快速地放置在机床上的适当位置并且自动地以各种位置为中心，可以将各个工具与工件进行所需的加工关系。工具可以包括固定和从动工具，并且机床适于允许工件和各个工具之间的相对运动，以便执行所需的加工步骤。在将载体单元放置在机床上之前，可以在其安装座上预先调整这些工具，并将其保存在载体单元上，以避免在不使用时产生工具损失。在机械工具期间，工具优选地保持在安装件中，但是在一个实施例中，工具可以从安装件中取出并传送到加工头。载体单元优选地是钟形的并且通过一对配合的环形环位于机床上。

摘要： A process for producing phosphorous-doped silicon monocrystals having a select peripheral depletion or enrichment of dopant atoms along the radial direction of such monocrystals comprises providing a silicon monocrystalline rod homogeneously doped with phosphorous, as by neutron doping, and subjecting such homogeneously doped monocrystalline rod to a peripheral zone melt cycle in a select atmosphere such that the peripheral melt zone depth within the monocrystalline rod is controlled so as to be less than the radius of the rod in accordance with the desired peripheral dopant concentration in the ultimately attained rod.

摘要： Polycrystalline semiconductor rods are converted to dislocation-free monocrystal rods by positioning a polycrystalline rod within a crucible-free zone melt environment with a seed crystal attached to one end thereof, generating a melt zone at the juncture of the seed crystal and the polycrystalline rod, controllably moving the melt zone away from the juncture and through the polycrystalline rod to a select point thereon, uniformly supporting the cone-shaped lower portion of the rod being processed so as to prevent oscillations and the like at the juncture of the rod in the seed crystal and controllably moving the melt zone from the select point to the remainder of the rod. A uniform support is preferably provided by an axially movable funnel-shaped casing which is attached to the seed crystal holding member and which, when moved into its operating position, is filled with a self-adjusting oscillation or vibration dampening means, such as molten metal, metal spheriods, quartz particles, sand, etc.
