  • Patent number: 10500099
    Abstract: A long-term effective patch structure includes a binding layer, an absorbing layer and a water-proof layer sequentially stacked together. The binding layer has a function of attaching and fixing, and is configured to be attached and fixed on a skin. Sweat or liquid from the skin can pass through the binding layer to reach the absorbing layer, which is aligned with binding layer at the edge. The water-proof layer is water-proof and has vapor permeability, and its area is larger than the area of the absorbing layer. The outer part of the water-proof layer is attachable to the skin. Since the absorbing layer can absorb the liquid from the skin and the water-proof layer can ventilate the vapor to the outside, the skin is kept dry and comfortable and suitable to be attached to human skin for a long period of time without inducing skin allergy or discomfort.

  • Patent number: 10381140
    Abstract: The present invention provides a method for preparing a rare earth permanent magnet material. The preparation method of the present invention comprises atomizing spray process and infiltrating process, wherein the atomizing-sprayed sintered rare earth magnet is placed in a closed container before infiltrating. Through the atomizing spray process a solution containing a heavy rare earth element is coated on the surface of a sintered R1-Fe(Co)—B-A-X-M rare earth magnet, and after baking, heat treatment is performed to infiltrate the sprayed heavy rare earth element to the grain boundary phase of the sintered rare earth magnet. This method decreases the amount of a heavy rare earth element used, increases the coercive force of magnets with a little decrease of remanence, decreases the remanence temperature coefficient and coercive force temperature coefficient of the magnet, and improves resistance of the magnet against demagnetization at a high temperature.
