  • MATRIX TRANSFORMER
    Publication number: 20250226144
    Abstract: In a matrix transformer used for a high-frequency switching power supply, two U-shaped ferrite cores each having two legs and one connecting part are used to form a core body by opposing butt surfaces of the legs thereof, whereby a closed magnetic circuit is formed, m+1 pieces of the core body are provided in order to form m magnetic circuits of the transformer, a row of the core bodies to be the magnetic circuits of the transformer is configured by one-dimensionally arranging the core bodies so as to be adjacent to each other, and a primary coil and a secondary coil wound around the legs are provided.

  • SINGLE CRYSTAL MANUFACTURING METHOD, SINGLE CRYSTAL MANUFACTURING APPARATUS AND CRUCIBLE
    Publication number: 20230082972
    Abstract: Miscellaneous crystals generated in a solution are reduced. A single crystal manufacturing method includes a first heating step of heating the solution so that a temperature of the solution in contact with a side surface of a crucible becomes higher than a temperature of the solution in contact with a bottom surface of the crucible, and a second heating step of heating the solution so that the temperature of the solution in contact with the bottom surface of the crucible becomes higher than the temperature of the solution in contact with the side surface of the crucible.
