  • Patent number: 5700381
    Abstract: After applying a metal film on a surface of a substrate, the metal film is patterned in such a manner that the surface of the substrate is exposed in a pattern that corresponds to the pattern of the required indented portion. Then, the substrate is immersed in an etchant which etches the substrate selectively to form the indented portion in the surface of the substrate using the metal film as a mask.The method makes it possible to define the depth and the pattern of an indented portion where a magnetic transducer is provided with a high degree of accuracy, to prevent a reduction in pattern accuracy due to re-adhering and to advance industrial productivity.

  • Patent number: 5143786
    Abstract: The present invention uses, as a base material, a multi-layer film comprising more than two layers and formed from thermoplastic resins different in melting point from one another. A sectional construction of the multi-layer film or a tape obtained from the multi-layer film is applied to a sectional construction of a fibre without modification, the multi-layer film or tape being formed into the fibre. The invention provides a composite fibre which is much more excellent as compared to a conventional heat adhesive composite fibre by melt spinning, a water-absorbing material using the composite fibre as a base material and a method for the production of the same by the stated simple means.

  • Patent number: 4931005
    Abstract: An apparatus for the preparation of an elastic absorbent composed of a mixed web. Elements of the apparatus can include two supply hoppers for separately supplying pulverized pulp and staple fibers of a synthetic fiber split yarn at a constant mixing ratio with each hopper having a pair of confronting moving belts, two guide mechanisms located below the hoppers, a pair of nip rollers located below the guide mechanisms, a garnet roll located below the pair of nip rollers, a vacuum device located below the garnet roll, and a mesh belt located between the vacuum device and the garnet roll. Each guide mechanism in the apparatus may include at least two gear guides arranged in series. The apparatus operates by feeding the pulverized pulp and the staple fibers of the split yarn from the hoppers to the nip rolls via the guide mechanisms. The nip rolls compress the material, which is then disintegrated and mixed by the garnet roll. The mixture is pulled onto the mesh belt by the vacuum device.
