摘要:
In acoustic panels employing a layer of perforate metal adhesively bonded to a layer of porous fibrous metal of a different type with the perforations of the perforated layer and the pores of the porous fibrous layers open to communication therethrough and the layers being isolated therebetween. The isolation between the layers is maintained by applying a coating of liquid epoxy resin material to selected locations, curing the epoxy coating, cutting or drilling the layers as required, and recoating the cut or drilled areas with a second coating of liquid epoxy resin.

摘要:
A low temperature process for forming a metal doped silicon layer in which a silicon layer is deposited onto a substrate at low temperatures, with a metal doping layer then deposited upon the silicon layer. This structure is then annealed at low temperatures to form a metal doped semiconductor having greater than about 1×1020 dopant atoms per cm3 of silicon.

摘要:
Disclosed is an electroplating method and products made therefrom, which in one embodiment includes using a current density J.sub.O, to form a conductive metal layer having a surface roughness no greater than the surface roughness of the underlying member. In another embodiment of electroplating a substrate surface having peaks and valleys, the method includes electroplating a conductive metal onto the peaks to cover the peaks with the conductive metal, and into the valleys to substantially fill the valleys with the conductive metal.

摘要:
A method of processing a substrate by first processing the substrate surface with a laser operating at a first wavelength to both evaporate a portion of the substrate and structurally weaken the substrate surface, and then by processing the substrate surface with a laser operating at a second wavelength to remove the structurally weakened surface.
