  • 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: 6435298
    Abstract: A rear underside structure of a vehicle as a rear undercover main body, an air flow path, an air intake opening, and an air exhaust opening. The rear undercover main body has an inclined planar part that rises toward the rear of the vehicle, and is disposed further to the rear of than the fuel tank, between the front and rear axles, so as to cover a drive element of the vehicle. The air flow path is disposed between the rear undercover main body and the drive element. The inclined planar part delineates at least a rear part of the air flow path. The air intake opening is disposed further to the front than the drive element, and the air exhaust opening is disposed to the rear of the inclined planar part. Air which flows in from the air intake opening passes through the air flow path, and is exhausted from the exhaust opening.
