    摘要： A portion of a conductive layer (310, 910) provides a capacitor electrode (310.0, 910.0). Dielectric trenches (410, 414, 510) are formed in the conductive layer to insulate the capacitor electrode from those portions of the conductive layer which are used for conductive paths passing through the electrode but insulated from the electrode. Capacitor dielectric (320) can be formed by anodizing tantalum while a nickel layer (314) protects an underlying copper (310) from the anodizing solution. This protection allows the tantalum layer to be made thin to obtain large capacitance. Chemical mechanical polishing of a layer (610) is made faster, and hence possibly less expensive, by first patterning the layer photolithographically to form, and/or increase in height, upward protrusions of this layer.

    摘要： A multilayer metal gasket has a pair of outer active layers separated by an intermediate layer. The outer active layers are formed with at least one pair of aligned apertures and sealing beads surrounding the apertures in radially outwardly spaced relation thereto presenting laterally opposed sealing surfaces of the active layers of predetermined spacing or thickness when the gasket is in a compressed free state. The intermediate layer extends radially inwardly beyond the apertures and is provided with a cold formed stopper portion having a thickness greater than the combined material thicknesses of the intermediate layer and outer active layers but less than the thickness of the sealing beads. The stopper portion is cold formed under a compressive load exceeding the compressive load required to deform the sealing beads beyond their elastic limit, thereby preventing irreversible damage to the sealing beads. The stopper portion presents opposing sealing surfaces which, when the gasket is clamped between two members having a passage to be sealed, serves as a primary seal or fire dam, shielding the sealing beads of the outer active layers from direct exposure to the heat of any fluid in the passage, such as hot exhaust gases of an internal combustion engine.

    摘要： A hybrid integration process for fabrication of an optical cross-connect switching apparatus. The switching element is based on the deflection of light beam in electro-optic materials by applying electric field across electrodes of an appropriate configuration. The integration process includes fabrication of a substrate (e.g. silicon substrate) with 2D imaging optics from polymeric materials (or silica), fabrication of the light deflecting element, and assembly of the deflecting element on the substrate with imaging optics. The fabrication of the light deflecting element includes fabrication of a LN (lithium niobate) block. The LN block assembled in an optical switching apparatus includes a two-dimensional waveguide formed on a surface of the LN block and an electrode on a surface of the LN block.
