    Abstract: A box-shaped enclosure of a storage box includes a deadening wall or walls defining a storage space between first and second planes. The storage space is open at the first and second planes. A deadening wall member extends along the first plane. An auxiliary box-shaped enclosure is connected to the box-shaped enclosure so as to close the first plane of the box-shaped enclosure. The auxiliary box-shaped enclosure defines an auxiliary space isolated from the storage space with a deadening wall member.

  • Publication number: 20120326703
    Abstract: A current measurement apparatus includes multiple GMR elements and a calculation unit. The multiple GMR elements each include a pinned magnetic layer having a pinned magnetization direction, and a free magnetic layer having a magnetization direction to be changed by an external magnetic field. The calculation unit obtains the magnitude of a current to be detected, from outputs of the multiple GMR elements. The multiple GMR elements are disposed in ring shape around a conductor through which the current to be detected flows, and are electrically connected so as to form a series variable resistor by using the multiple GMR elements. The magnetization directions of the pinned magnetic layers are pinned in the same direction when viewed from an extension direction of the conductor at each of the positions of the elements.
