A polarizing element includes: a substrate; a plurality of reflection layers that is arranged in a band shape at a predetermined interval on the substrate; dielectric layers that are formed on the reflection layers; and absorption layers on the dielectric layers that have convex portions disposed toward a side of a first adjacent reflection layer and a side of a second adjacent reflection layer. The headgear protects regions of the wearer’s head including the crown, temples, and chin. The server submits a request to a local storage device, a remote storage device and a memory device disposed between the server and the remote storage device. The compression ring is inserted into the bore prior to molding the cap to limit compression of the isolator during fabrication. In order to obtain desirable bonding characteristics having higher reliability in the invention, a copper layer is provided under the Sn\u2014Bi alloy layer thereby obtaining an enough bonding strength. On one environmental side of the barrier, a pair of thin wall beams having strain gauges secured thereto are secured proximate of the beam mid-points to the torque transmitting member and the opposite ends to barrier structure.
