Abstract: The present invention provides a method for preparing an activated carbon, which includes impregnating a carbonaceous material with carbonated water; and exposing the carbonaceous material to microwave radiation to produce the activated carbon.

Abstract: A display panel includes a substrate and a plurality of pixel structures disposed on the substrate. Each of the pixel structures includes a first light-emitting element, a second light-emitting element, and a third light-emitting element. The first light-emitting element is disposed on the substrate and configured to generate a first colored light. A light output surface of the first light-emitting element includes a combined region. The second light-emitting element is disposed on a part of the combined region and configured to generate a second colored light. The third light-emitting element is disposed on the other part of the combined region and configured to generate a third colored light.

Abstract: An ankle therapy apparatus in which a reversible motor is mounted on a support at a rotary table in a base frame to rotate a gear transmission mechanism and a footplate is pivoted to the support and coupled to the gear transmission mechanism and turned alternatively upwards and downwards during operation of the reversible motor, and a clutch gear is selectively set to couple the gear transmission mechanism to the rotary table for causing rotation of the rotary table during the motion of the footplate.

Abstract: A hanging ring used in a curtain by punching from a metal sheet comprises: a ring body containing a ring piece having a round hole, an extending piece one end of which extends from the ring piece and an extending bar extending from another end of the extending piece. One end of the extending bar is pressed as a rivet end for being fixed in a clip. A lateral extending frame is punched from lateral sides of the enhancing edge and the extending piece. The lateral extending frame has a non-plane locking ring. A locking hole is punched from the plane locking ring. The non plane locking ring is twisted through an angle so that it is at different orientation from the other part of the lateral extending frame. An inner wall of the locking hole is a threaded wall for locking a screw rod of a decoration.
