Abstract: Control methods and apparatuses providing a holding current for a TRIAC dimmer are disclosed. A control method is suitable for a power controller powered by an operation power source. A high-voltage device in the power controller is connected between the operation power source and an input power source, from which the high-voltage device drains a conduction current.

Abstract: A movable jaw quick release apparatus of a vice comprises a tooth base, a movable jaw and two restriction elements. The tooth base is formed with two inclined guide grooves, each of which has a first inclined surface, a second inclined surface and a bottom surface. The left and the right side surfaces of the movable jaw are formed with a through hole respectively. Each restriction element penetrates one of the through holes and moves between a first position and a second position along one of the inclined guide groove As the movable jaw generates vibration forces, each restriction element transfers the vibration forces to the tooth base, therefore, the movable jaw do not move upwardly and shake toward a work piece and reduce its clamping force for the work piece.

Abstract: A composite material comprising of carbonated hydroxyapatite and biopolymer was synthesized in the form of microsphere for biomedical applications via a novel colloidal technique. Novel colloidal suspensions were prepared by mixing phosphate salts, calcium salts and carbonate precursors with size ranging from nanometer to submicrometer, together with sufficient amount of biocompatible polymers, following by spherorization to form microspheres of various sizes. Nanostructure of the constituents allows final apatitic phase to be developed upon moisture exposure. Biologically or therapeutically active drugs can be encapsulated directly into the microspherical composites upon synthesis for biomedical applications such as orthopedics, dentistry, and drug delivery.
