摘要： A liquid adhesive coating composition that cures into a solid form, used to non-permanently adhere interior floor or wall coverings to substrate floor or wall surfaces respectively, includes a polymer incorporating iron or other paramagnetic, superparamagnetic, ferromagnetic, or ferrimagnetic ingredients, that becomes permanently adhered to the substrate as it cures, and thereafter provides a low-tack adhesive surface that is also magnetically attractive, upon which magnetized floor or wall coverings including certain types of carpet, linoleum, vinyl, wallpaper, and other types of magnetically-backed coverings can be subsequently installed. The combined low-tack adhesive and magnetic adhesion qualities of the cured composition of the invention allow for the magnetically-backed floor or wall coverings to be sufficiently well adhered to the surface of the cured adhesive composition to remain in place during normal usage while retaining the ability for the coverings to be subsequently removed, repositioned or replaced without damaging the respective coverings, adhesive coating composition layer, or substrate.

摘要： A method for manufacturing a powder magnetic core using a soft magnetic material powder, wherein the method has: a first step of mixing the soft magnetic material powder with a binder, a second step of subjecting a mixture obtained through the first step to pressure forming, and a third step of subjecting a formed body obtained through the second step to heat treatment. The soft magnetic material powder is an Fe—Cr—Al based alloy powder comprising Fe, Cr and Al. An oxide layer is formed on a surface of the soft magnetic material powder by the heat treatment. The oxide layer has a higher ratio by mass of Al to the sum of Fe, Cr and Al than an alloy phase inside the powder.

摘要： Embodiments disclosed herein relate to using cobalt (Co) to fine tune the magnetic properties, such as permeability and magnetic loss, of nickel-zinc ferrites to improve the material performance in electronic applications. The method comprises replacing nickel (Ni) with sufficient Co+2 such that the relaxation peak associated with the Co+2 substitution and the relaxation peak associated with the nickel to zinc (Ni/Zn) ratio are into near coincidence. When the relaxation peaks overlap, the material permeability can be substantially maximized and magnetic loss substantially minimized. The resulting materials are useful and provide superior performance particularly for devices operating at the 13.56 MHz ISM band.
