Abstract: This utility model provides a roller-type electronic watch comprising a watch body and a watch strap. The watch body includes a watch case, rollers, drive devices, a control circuit board and a battery. A character or pattern is set on the peripheral surfaces of the rollers. The control circuit board controls the drive devices to move. The drive devices drive the rollers to rotate, so that the peripheral surfaces of the rollers display information from the window of the watch case. The roller-type electronic watch of this utility model has a unique display manner and has special sporty feel.

Abstract: We provide methods and apparatus for preparing crystalline-clad and crystalline core optical fibers with minimal or no breakage by minimizing the influence of thermal stress during a liquid phase epitaxy (LPE) process as well as the fiber with precisely controlled number of modes propagated in the crystalline cladding and crystalline core fiber via precisely controlling the diameter of crystalline fiber core with under-saturated LPE flux. The resulting crystalline cladding and crystalline core optical fibers are also reported.
