Abstract: The present disclosure relates to the technical field of glass tempering, and in particular to a method and apparatus for weakening stress patterns of tempered curved glass. A through continuous reversible deformation cavity replaces an original split-type air box to serve as an air grid. A fluid smoothing structure is distributed in the cavity and configured for reducing fluid resistance. An outlet airflow orienting and stabilizing structure is distributed outside the cavity and configured for constraining the direction, flow velocity and flow quantity of a jetted airflow. A butt-joint device capable of changing with the curvature of the cavity surface is arranged between the cavity and an air supply source for the cavity.

Abstract: The present invention provides a electric generator with novel structure, comprising two parts: a stator and a rotor. The stator has rectangle-section winding slots. The stator teeth have sectorial section. Slits are formed extending axially in the yoke and the magnet poles laid on the yoke in the rotor. The stator windings are made up of square-wave open rings with different pitches. The generator of the present invention has much less weight and smaller size, and the manufacturing process is simple, the consuming of copper and silicon steel sheets can be reduced, the efficiency is higher and energy can be saved.
