  • Publication number: 20240153680
    Abstract: Provided is a rare-earth anisotropic magnet powder capable of achieving high magnetic properties while reducing the usage of Nd and Pr. The present invention provides a rare-earth anisotropic magnet powder comprising magnetic particles that contain rare-earth elements, boron, and a transition metal element. The rare-earth elements include a first rare-earth element that comprises Ce and/or La and a second rare-earth element that comprises Nd and/or Pr. The rare-earth elements have a first ratio (R1/Rt) of 5% to 57%. The first ratio (R1/Rt) is a ratio of an amount (R1) of the first rare-earth element to a total amount (Rt) of the rare-earth elements in terms of the number of atoms. The first rare-earth element has a La ratio (La/R1) of 0% to 35%. The La ratio (La/R1) is a ratio of an amount of La to the amount (R1) of the first rare-earth element in terms of the number of atoms. The magnetic particles have a Ga content of 0.35 at % or less with respect to 100 at % as a whole.

  • Patent number: 11305495
    Abstract: An adhesive injection method is for injecting an adhesive that bonds an outer plate and a reinforcing member. The reinforcing member has through holes bored through the reinforcing member in a direction intersecting a bonding surface facing the outer plate. The method includes positioning the outer plate and the reinforcing member; disposing a sealing material covering a gap between the outer plate and the reinforcing member; and injecting the adhesive into the through holes in order from one end to the other end of the bonding surface. At the injecting, while the adhesive is injected into the through hole, when the adhesive is recognized through another through hole formed adjacent to the through hole into which the adhesive is being injected, a through hole into which the adhesive is to be injected is shifted from the through hole into which the adhesive is being injected to the other through hole.
