Abstract: A centrifugation process to increase solid containment in a powdered paste is related to a fast, simple and higher value added process. The paste availed from a primary centrifugation is blended to destroy powder bridge in the paste. The solid and the liquid are further separated with a secondary centrifugation to significantly improve centrifugation efficiency and help avail the paste with a higher solid containment. The powder is constantly distributed due to the blending thus to minimize potential flaws found in the subsequent process.

Abstract: A processing method for ceramic, having processing steps consisting of: (a) Manufacture pellets; (b) Cover the pellets with microwave dielectric; (c) Place the pellets into a microwave environment; (d) Microwave degreasing; (e) Complete degreasing. Procedural steps of the present invention primarily consist of placing the ceramic pellets in a container filled with microwave dielectric powder, placing the container within the microwave environment, and then regulating microwave power and time period for degreasing, whereupon the microwave dielectric powder surrounding and covering the pellets subsequently absorbs the microwaves and thereby facilitates indirect degreasing of the pellets.

Abstract: A method of manufacturing silver flake, whereby characteristic of a plating film of providing uniform thickness is utilized, and material selected for use as a substrate is that which is easily removed and broken. First, a layer of silver metal is plated on a surface of the substrate, whereafter such test specimen is crushed and the substrate removed, or first remove the substrate material and thereafter crush, and that which remains is silver powder of extremely uniform thickness. The silver flake thus acquired is provided with superior thermal and electrical conductivity in a specific direction.

Abstract: A wireless earphone with a replaceable battery module has a body having the function of a wireless earphone and a hook having a battery module therein. A cavity is formed on the body. Two conducting sheets are provided near the cavity. The two conducting sheets are connected to a power source circuit in the body. Two conducting contacts are formed at one end portion of the hook. The two conducting contacts are connected to a power source circuit of the battery module. When one end portion of the hook is inserted into the cavity in the body, the two conducting contacts contact the two conducting sheets at two sides of the body so that the battery module can provide electricity to the body. When the electricity of the module is insufficient, the hook can be replaced to recharge the battery module for further use.
