In a battery operated electric timepiece operated by a battery of the type including a time display, such as a second hand, when the voltage of the battery decreases below a predetermined value, the movement of the second hand is modified to give an alarm that the life of the battery has terminated.
摘要:
In magnetic tunnel junctions manufactured with use of a ferromagnetic material having perpendicular magnetic anisotropy, a difference in record retention time depending on stored information due to an imbalance in thermal stability between a parallel state and an anti-parallel state of magnetization, which correspond to bit information, is alleviated. A reference layer and a recording layer which constitute a magnetic tunnel junction are made different in area from each other so as to correct the difference in record retention time corresponding to stored information.

摘要:
A vein authentication apparatus is disclosed. The apparatus may include an imaging unit having a plurality of imaging sections. Each imaging section may be configured to image light reflected from a vein plexus inside a finger and light transmitted through the vein plexus. The apparatus may also include an illumination source located on the same side as the imaging unit with respect to the vein plexus and configured to emit near-infrared light. The apparatus may further include a controller. The controller may be configured to perform authentication processing on the basis of an image imaged by the imaging unit and vein information previously stored. The controller may also be configured to control the illumination source such that the near-infrared light emitted from the illumination source is scattered behind a vein section corresponding to an imaging section being in an imaging period among the plurality of imaging sections.
