Abstract: A phosphor material for producing white light under excitation of UV light and a method for making the same. The phosphor material is an alkaline-earth silicates compound with a chemical formula of (A2-x-yCexEuy)SiO4. A is one or more elements selected from the collection of Ba, Sr and Ca alkaline-earth metals. The range of x and y correspond to 0<x<1.0 and 0<y?0.5 respectively. The phosphor material requires two rare earth elements: Ce and Eu. By blending the best co-doped composition of Ce and Eu ions, the single phosphor can directly produce white light under UV light excitation. In addition, the material in this invention is easy and fast to prepare in a large amount. Therefore, the phosphors can have a high industrial value.

Abstract: A light emitting diode and a method for making the same are proposed. The LED comprises an inorganic phosphor, a silicon compound and an organic glue. The silicon compound has one side being completely or partially C1-C6 alkyl oxide reacted with the inorganic phosphor to modify the surface property of the inorganic phosphor and another side being a functional group selected from a group consisting of epoxy, C1-C6 alkyl, phenyl, amino. The inorganic phosphor with modified surface property can be uniformly mixed in the glue and less deposition is produced.

Abstract: A table fork includes a fork handle and a fork body. The fork body has a base plate having a plurality of protruding main and assistant tines arranged around on an upper surface, possible to fork and hold several pieces of food at one time, letting an eater feel satisfied with eating with a mouthful without soiling a hand, and also able to keep forked food steady on the tines, preventing forked food from dropping down or dangling around.

Abstract: The present invention provides a transforming method for increasing bit number of digital image signals generated by a scanner. The scanner comprises a scanning module having a plurality of linearly arranged sensors for scanning a document and generating a plurality of corresponding analog image signals, an A/D (analog to digital) converter for converting each of the analog image signals into a digital image signal with a first bit number, and a white calibration area and a black calibration area for calibrating the scanning module.

Abstract: A biasing system for an FET utilizes a source biasing capacitor which is charged to a positive DC ground voltage relative to RF ground. The gate of the FET is thus biased negative to the source without requiring a negative power supply.

Abstract: An apparatus and method of attaching I/O pads of an integrated circuit die to package leads. The attachment is made using conventional assembly processes but without using wire bonding. A leadframe with lead fingers is formed and the lead fingers are aligned with bumps extending from the I/O pads. A connection is made by physical contact, laser spot welding, or other coupling techniques.
