  • Patent number: 9833982
    Abstract: A method and a process for the production of high pressure laminate is disclosed using conventional manufacturing equipment without the use of melamine-formaldehyde resin pre-impregnated decorative print, solid, or overlay papers or combinations thereof. The method and process of making the disclosed laminate product utilize the assembly of a plurality of pre-impregnated Kraft papers independently saturated with melamine-formaldehyde resin, phenol-formaldehyde resin, and/or a bilayer coated construction of Kraft paper simultaneously containing both resins on opposing surfaces. The resulting pre-impregnated Kraft based components are assembled into the core layer and combined with the desired decorative layer assembly composed of untreated decorative print, solid, and/or overlay papers, or combinations thereof, prior to consolidation into a finished laminate using standard heat and pressure commonly known to those skilled in the art.

  • Patent number: 7658998
    Abstract: The present invention relates to a method for preparing an injectable composition of microparticles for the sustained release of a biologically active agent. The microparticles include a biocompatible polymer and a biologically active agent. The invention provides an improved process for the preparation of microparticles, wherein the physical characteristics of the microparticles, for example, the morphology, density and size, are independent of the process used to prepare the initially formed polymer/drug matrix. The method includes the steps of (a) providing a polymer/biologically active agent matrix; (b) compressing the polymer/biologically active agent matrix, thereby forming a compressed matrix; and (c) fragmenting the compressed matrix, thereby forming an injectable microparticle composition. The polymer/drug matrix can be provided by any suitable method.

  • Patent number: 5958611
    Abstract: According to the present invention, a magnetic multilayered film includes an oxide antiferromagnetic layer, a pinned ferromagnetic layer which is pinned by the oxide antiferromagnetic layer, a non-magnetic metal layer and a free ferromagnetic layer which are stacked on a substrate in order. A surface roughness Ra of the oxide antiferromagnetic layer at the side of the pinned ferromagnetic layer is set to no greater than 0.6 nm, and a crystal grain size D of the oxide antiferromagnetic layer is set to a value in the range of 10 to 40 nm. Thus, the magnetic multilayered film has the large exchange-coupling magnetic field and MR ratio and MR sensitivity. The magnetic multilayered film may be applied to a magnetoresistance effect element which may also applied to a magnetoresistance device, such as, a magnetoresistance effect type head. The magnetoresistance effect element having such a magnetic multilayered film is capable of obtaining high outputs.

  • Patent number: 5766780
    Abstract: The present invention includes a magnetoresistive type sensor having a first sensor layer of NiFe and a first layer of antiferromagnetic material, preferably NiMn. Portions of the first NiFe layer are deposited directly on top of the first layer of antiferromagnetic material such that the portions of the first NiFe sensor layer are in contact with the first layer of antiferromagnetic material. The first layer of antiferromagnetic material exchange couples with the first NiFe sensor layer to thereby provide domain stabilization of the first NiFe sensor layer. The first layer of antiferromagnetic material is deposited directly on top of a first baselayer of molybdenum to enhance the exchange coupling between the first NiFe sensor layer and the first antiferromagnetic layer.
