A magnetic refrigerator includes independent hot heat exchange unit and cold heat exchange unit wherein separate heat transfer fluids are circulated. The developing sleeve and the image bearing member rotate in the same direction while facing each other. With the invention, crosstalk test can be implemented in real time on xSDL lines without impacting the transmission performance of other lines. Based on information obtained, the mobile device creates a reply customized SMS message. In relatively long sun visors, the integrally formed pin member advantageously provides the structural integrity needed to substantially prevent torsional deformation of the sun visor assembly as it is moved from a storage position adjacent a vehicle headliner to a use position adjacent the vehicle windshield. In the mercury-free arc tube in which an inert gas is sealed in the shroud glass tube that surrounds the closed glass sphere, in the shroud glass tube, the adjustment is made so as to satisfy the light flux and the life span with respect to the pressure X of a rare gas sealed in the closed glass sphere, and an amount M of sealed metal halide.
