A rare earth magnet molding () of the present invention includes rare earth magnet particles (), and an insulating phase () present among the rare earth magnet particles. Segregation regions () in which at least one element selected from the group consisting of Dy, Tb, Pr and Ho is segregated are distributed in the rare earth magnet particles (). Accordingly, the rare earth magnet molding that has excellent resistance to heat in motor environments or the like while maintaining high magnetic characteristics (coercive force) is provided.

A magnetostrictive stress sensor () includes: a magnetic member {, ()} having a magnetostriction; a permanent magnet () adjacent to the magnetic member; a magnetic sensor (A,B) for detecting a leak magnetic flux on a side opposite to the permanent magnet with respect to the magnetic member, wherein the leak magnetic flux changes according to a stress acting on the magnetic member and the magnetic sensor detects the change of the leak magnetic flux, to thereby detect the stress acting on the magnetic member, and a direction (A,A) of the stress acting on the magnetic member is substantially orthogonal to a magnetizing direction (A) of the permanent magnet.

Magnetostrictive stress sensor

An airbag inflator comprises a housing having an interior and gas outlet ports communicating with the interior and open to outside the housing. First and second divider walls separate at least two gas chambers from the interior. A pressurized combustible gaseous mixture is stored in each gas chamber. An initiator is disposed within each gas chamber and actuatable to ignite the pressurized combustible gaseous mixture.
