  • Patent number: 5876835
    Abstract: Stressed-skin panels are provided having internal open-cell grids molded from material such as fibers, and methods and apparatus for the production thereof are disclosed. The invention utilizes a porous screen having a plurality of elastomeric pads spaced apart thereon. Fiber dispersed in fluid is introduced into the apparatus and over and around the pads. Pressure exerted thereon expels fluid through the screen and consolidates the fibers to form a panel. The pads are designed and constructed in a manner so as to consolidate the fiber mat located below the pads compressed by the pressure, so that the finished panel includes an integrally-molded flange. The height, shape and/or spacing of the pads in the present invention advantageously provide improved mold release and greater resistance to compression set after repeated use. The pads provide greater consistency and improved quality in the flange formation on the panels.

  • Patent number: 5876838
    Abstract: A semiconductor integrated circuit is made by a process including the formation on a surface of a semiconductor integrated circuit processing wafer of a layer of material applied to the wafer by plasma enhanced chemical vapor deposition (PECVD). The layer of material may include plural sub-layers, the thicknesses of which are additive to result in the thickness of the layer of material itself. The sub-layers of material may have non-uniform thicknesses across a dimension of the processing wafer because of compromises in the process which are necessary to control various parameters of the material layer other than its thickness. These non-uniformities of thickness of the sub-layers may be controlled to offset one another so that the resulting layer of material has a substantially uniform thickness across the dimension of the processing wafer.

  • Patent number: 5876842
    Abstract: A modular structure for providing electrical interconnections achieves greatly increased wiring density by forming vias and wiring patterns by chemical (e.g. lithographic) processes rather than by mechanical processes such as punching of vias and screening patterns of conductive paste. A basic module is a power core comprising an apertured metallic foil with an insulator applied to surfaces thereof, extending through at least one aperture and exposing the metallic foil in at least one aperture. The foil in the power core provides stiffness to facilitate subsequent handling and electrical shielding between conductive layers as well as a potential power connection. Via connections of increased conductivity and robustness are formed by plating the interior of vias after lamination of a desired combination of power cores and signal cores.

  • Patent number: 5876848
    Abstract: A method of forming a magnetic structure having layers with different magnetization orientations provided by a common magnetic bias layer includes the steps of depositing an antiferromagnetic layer between first and second ferromagnetic layers. During the deposition of the first and second ferromagnetic layers, magnetization fields of different orientations are employed separately to induce different directions of magnetization in the first and second layers. The different directions of magnetization in the first and second layers are sustained, through the process of exchange coupling, by the interposed antiferromagnetic layer which serves as the bias layer. A magnetic structure thus fabricated, can be used as a read transducer capable of generating differential signals with common mode noise rejection, and can be used as a magnetic pole for a magnetic head with reduced Barkhausen noise.

  • Patent number: 5876870
    Abstract: At step S21, a residual amount judging section of abattery residual amount display circuit measures a battery voltage. If a mode transition is detected at step S22, the process returns to step S21 without executing the subsequent steps. If it is judged at step S23 that the operation mode is a reception-waiting mode, the process goes to step S24, where the battery amount judging section judges a battery residual amount by comparing the detected battery voltage with threshold values. If the operation mode is judged to be a transmission mode, the battery residual amount judging section determines a voltage drop during a transmission at step S25, and converts the voltage drop into a battery voltage of a reception waiting mode at step S26 by subtracting the voltage drop from a batter voltage obtained in a reception waiting mode immediately before the mode transition.

  • Patent number: 5876880
    Abstract: A process is disclosed for producing a structured mask for use in reproducing structures of that mask on an object with the aid of electromagnetic or particulate radiation, in particular for ion beam lithography. A flat smooth substrate of more than 20 .mu.m in thickness is selected and a thin diaphragm is produced from that substrate by etching one of the sections removed from the edging to a depth of c. 0.5-20 .mu.m, the tensile stress within the diaphragm being greater than 5 MPa. Lithographic structures are then formed on a central region of the diaphragm with a tensile stress of more than 5 MPa; apertures are etched into the diaphragm to form the mask structures and the effective thickness inside a diaphragm region substantially enclosing the mask structures is reduced, causing the central region containing the structures to be joined to the substrate edging elastically in such a way that the mean tensile stress within this central region is reduced to below 5 MPa.

  • Patent number: 5876881
    Abstract: Methods are disclosed for manufacturing masks for charged-particle-beam (CPB) or X-ray transfer. The masks have substantially no pattern defects. In a representative method for making stencil masks, the mask is defined using multiple subfields each having a respective pattern of voids. The subfields are separated from each other by boundary regions lacking any pattern features. The boundary regions include supports to provide the mask with physical and thermal stability. The supports are formed by an etching step in which relatively large amounts of substrate are removed. In the methods, the mask pattern is formed, inspected, and "repaired" as required before performing the etching step that forms the supports. Thus, the forming, inspection, and repair steps can be performed before the mask is made too delicate.
