  • Patent number: 10781512
    Abstract: A method for coating a body includes providing a plurality of granules in which each granule includes silicon (Si), carbon (C), chromium (Cr) and an iron group metal. The relative quantities of the Si, C and Cr are such that a molten phase will form at a melting temperature of less than 1,300 degrees Celsius when a threshold quantity of the iron group metal is accessible to the Si, C and Cr. A second source of the iron group metal is also provided. A combination of the granules and the second source is formed such that the threshold quantity of the iron group metal will be accessible to the Si, C and Cr. The granules and the second source are heated to the melting temperature to form the molten phase in contact with the body. The heat is then removed to allow the molten phase to solidify.

    Abstract: There are provided a rare-earth permanent magnet and a manufacturing method of a rare-earth permanent magnet capable of preventing deterioration of magnet properties. In the method, magnet material is milled into magnet powder. Next, a mixture 12 is prepared by mixing the magnet powder and a binder, and the mixture 12 is formed into a sheet-like shape to obtain a green sheet 14. Thereafter, magnetic field orientation is performed to the green sheet 14, which is then held for several hours in a non-oxidizing atmosphere at a pressure higher than normal atmospheric pressure, at 200 through 900 degrees Celsius for calcination. Thereafter, the calcined green sheet 14 is sintered at a sintering temperature. Thereby a permanent magnet 1 is manufactured.

  • Patent number: 10760016
    Abstract: A gasifier system includes a reactor for receiving a wet feedstock which has a base and a container rotatably connected to the base such that a rotation of the container causes a mixing of the feedstock in an interior of the reactor. The interior is bounded by the base and the container. A space between the base and the container allows an entry of oxygen into the interior. The space has a dimension such that the feedstock is fully oxidized in a combustion area adjacent the base and such that the feedstock avoids combustion in a remainder of the interior. The reactor has a longitudinal axis inclined at an inclination angle relative to a horizontal line to promote the mixing of the feedstock in the interior.
