  • Patent number: 5758697
    Abstract: A weaving method that imparts a 1/f fluctuation to the weave pattern. Adjacent and different numbered groups of different yarns, for example black yarn and white yarns, are alternately arranged in contiguous reed dents. The sequential number which is associated with each group manifests a series of numbers which effect the 1/f fluctuation. Following separation of the warp yarns into two sets by raising and lowering of healds to form a shed and passage of weft yarns therethrough, a woven fabric with a stripped 1/f fluctuation in the warp direction is created.

  • Patent number: 5727600
    Abstract: A weaving method that imparts a correlation of a 1/f fluctuation to the texture pattern of a woven fabric by passing warp yarns through a plural number of healds in a specific numerical sequence. The healds are then manipulated to separate the warp yarns into two sets to form a shed therebetween through which a weft yarn is inserted. For one texture pattern, warp yarns are threaded in groups in numbers corresponding to the values of a numerical sequence with a 1/f fluctuation through one set of healds. For another texture pattern, warp yarns are threaded in groups through another set of healds so as to alternate with the first groups, thereby weaving a plural number of texture patterns into the woven goods, with the overall texture design having a 1/f fluctuation.

  • Patent number: 5589668
    Abstract: A multi-metal layer wiring TAB tape carrier capable of forming a fine pattern without affecting the thicknesses of conductive metal layers, and a process for fabricating the multi-metal layer wiring TAB tape carrier. This TAB tape carrier is constructed such that respective dielectric film layers are interposed between adjacent ones of plurality of conductive metal layers having a predetermined wiring pattern, such that the dielectric film layer is formed with interfacial connection holes, and such that a conductive via layer is formed in the interfacial connection holes to electrically connect adjacent conductive metal layers. The conductive via layer is formed by a vapor deposition method such as evaporation, ion plating or sputtering. Alternatively, a portion of the conductive metal layers and the conductive via layer are simultaneously formed.
