摘要： The invention relates to a method for manufacturing a moulded body, particularly a prototype of a product or component part, a tool prototype or spare part, in accordance with three-dimensional CAD data of a model of a moulded body, by depositing layers of a metallic material in powder form. Several layers of powder are successively deposited one on top of the other, whereby each layer of powder is heated to a specified temperature by means of a focused laser beam applied to a given area corresponding to a selected cross-sectional area of the model of the moulded body, before deposition of the next layer. The laser beam is guided over each layer of powder in accordance with the CAD cross-sectional data of the selected cross-sectional area of the model in such a way that each layer of powder is fixed to the layer below it. The method is characterized in that the metallic material in powder form is applied in the form of a metallic powder free of binders and fluxing agents, that it is heated by the laser beam to melting temperature, that the energy of the laser beam is chosen in such a way that the layer of metallic powder is fully molten throughout at the point of impact of said laser beam, that the laser beam is guided across the specified area of powder in several runs in such a way that each run of the laser beam partly overlaps the preceding run, and that a protective gas atmosphere is maintained above the interaction zone of the laser beam and the metallic powder.

摘要： A product building system uses a stage (13) movable in X-Y-Z directions for holding and moving a product. A fixed laser (1) is focused on a spot on the product while strips of materials (7) are fed tangent to a forming direction from two sources (6, 32) on a rotating platform (11). The laser continuously or periodically welds and fuses a strip to the product. Relative motion bends the strips to a desired product shape, and the laser cuts a strip and welds a new strip to form alternating material layers. Side by side strips are butt-welded and product cores may be formed differently from outer surfaces. A mill (30) in the rotating platform brings a mill end tool (31) into contact with the layers to smooth lateral and upper surfaces. Ceramic strips are delivered heated and solidified, compensating for shrinkage as the part is being built.

摘要： The present invention is a sensor formed over a subminiature through hole. Because of the small diameter of the through hole, the material that fills the through hole and the through hole itself have an essentially negligible effect on the sensor. Only a small amount of conductive material which fills each through hole is in contact with each associated electrode. Therefore, the purity of the electrode is not significantly altered by the conductive material coupled to the electrode. A relatively large number of sensors can be formed on the surface of the substrate within a relatively small fluid flowcell. Thus, more information can be attained using less blood. The sensors of the present invention are preferably disposed on an alumina substrate which is essentially impervious to aqueous electrolytes and blood over long periods of storage in potentially reactive environments. Since the substrate on which the sensors are deposited does not break down or become unstable when exposed over time to such reactive environments, the isolation that is provided by the substrate remains very high between each sensor and each other sensor, between each sensor and each conduction path, and between each conduction path and each other conduction path. The superior isolation provided by the substrate provides for a high level of accuracy in the sensor of the present invention. Furthermore, the use of the through holes allows the conduction paths between the electrodes of the sensors and any external devices to be exclusively on the opposite side of the substrate from the sample. This physical isolation of the sample from the conduction paths between the sensor electrodes and external devices ensures very high electrical isolation between each of the sensors is maintained over an extended period of time during which reactive fluids (such as electrolytes and/or blood) are present in the flowcell.
摘要翻译：本发明是形成在超小型通孔上的传感器。由于通孔的直径很小，填充通孔的材料和通孔本身对传感器具有基本上可以忽略的影响。只有少量的填充每个通孔的导电材料与每个相关电极接触。因此，电极的纯度没有被耦合到电极的导电材料显着改变。可以在相对较小的流体流通池内的基板的表面上形成相对大量的传感器。因此，可以使用较少的血液获得更多的信息。本发明的传感器优选设置在氧化铝基底上，氧化铝基底在潜在的反应性环境中长时间储存时基本上不渗透水性电解质和血液。由于传感器沉积在其上的基板在随时间暴露于这种反应性环境中时不会分解或变得不稳定，所以基板提供的隔离在每个传感器和每个传感器之间在每个传感器和每个传导之间保持非常高路径，并且在每个传导路径和彼此传导路径之间。由衬底提供的优越的隔离在本发明的传感器中提供高水平的精度。此外，通孔的使用允许传感器的电极和任何外部装置之间的传导路径完全在与样品相反的基底上。样品与传感器电极和外部设备之间的传导路径的这种物理隔离确保了每个传感器之间的非常高的电气隔离保持在反应流体（例如电解质和/或血液）存在的延长的时间段内在流通池中。

Date Sep. 25, 1997The invention concerns a method for laser cutting metal workpieces which contain bound oxygen by using a mixture of ay least one inert gas and hydrogen as the cutting gas. The hydrogen protein of the cutting gas prevents oxygen which is from the metal during the cutting process from causing undesired oxidation in the region of the cutting point. The formation of burrs and furrows is thus prevented.

摘要： A method of butt welding a pair of sheets (30, 32) minimizing or eliminating edge preparation of filler metal. Sheet edges (34, 36) are abutted with a surface mismatch (48) so that a portion (88) of the edge of the mismatched sheet (32) is above the weld interface (58) and exposed to the high energy radiation welding beam (40). The sheets (30, 32) are inclined at an acute angle from the horizontal plane (54) and transverse to the welding direction so as to encourage the flow of molten metal from the mismatched sheet (32) into the weld interface (58) region. The sheets (30, 32) can also or alternatively be inclined so as to introduce an acute angle between the weld line (56) and the horizontal plane (54), sloping downward in the welding direction (104), to minimize weld defects. The completed weld (44) forms a sheet blank that can be formed or contoured.

摘要： In one aspect the invention provides a method for laser induced breakdown of a material with a pulsed laser beam where the material is characterized by a relationship of fluence breakdown threshold (Fth) versus laser beam pulse width (T) that exhibits an abrupt, rapid, and distinct change or at least a clearly detectable and distinct change in slope at a predetermined laser pulse width value. The method comprises generating a beam of laser pulses in which each pulse has a pulse width equal to or less than the predetermined laser pulse width value. The beam is focused to a point at or beneath the surface of a material where laser induced breakdown is desired. The beam may be used in combination with a mask in the beam path. The beam or mask may be moved in the X, Y and Z directions to produce desired features. The technique can produce features smaller than the spot size and Rayleigh range due to enhanced damage threshold accuracy in the short pulse regime.
