  • REAL-TIME MANAGEMENT SYSTEMS AND METHODS FOR MANUFACTURING MANAGEMENT AND YIELD RATE ANALYSIS INTEGRATION
    Publication number: 20060241802
    Abstract: A real-time management method for manufacturing management and yield rate analysis integration. A plurality of yield rates relating to wafer products are summed and averaged for a historical yield rate. Multiple representational inline QC parameters are selected. A statistical process is implemented and, if no extreme value and collinear parameter exists and if analysis results satisfy normal distribution, multiple optimum inline QC parameters are selected from the representational inline QC parameters. Weights of each optimum inline QC parameter are calculated. A predicted yield rate is calculated according to the historical yield rate, weights, and a plurality of measurement and target values relating to the wafer products.

  • Lamp holder
    Publication number: 20060221623
    Abstract: A lamp holder includes a body provided with a recessed room, a metal helical cylinder fitted in the recessed room for a lamp bulb to screw with. The body has a through hole vertically in the body, and an elastic conductive unit is positioned in the through hole. A central conductor is fixed at the bottom side of the body, located at one side of the through hole and connected with one terminal of electricity. The elastic conductive unit consists of a coil spring and a conductive rod fitted around by the coil spring. The conductive rod has its lower end normally separated from the central conductor by the elasticity of the coil spring. Unless a lamp bulb is screwed in the helical cylinder completely, it cannot push down enough the conductive rod to let electricity get through to light up the lamp bulb. Thus the safety of the lamp holder is enhanced.

  • BLU and module using the BLU
    Patent number: 7080933
    Abstract: A BLU module has a plurality of BLUs assembled together. Each of the BLUs includes a light guide, a light source structure adjacent to the light guide, and a heat conduction member contacting the light source structure. The light guide has a light-emitting surface arranged on a top thereof and a bottom surface opposing the light-emitting surface, the light-emitting surface being larger than the bottom surface so that that light guide defines a first cavity formed therebetween. The light source structure is received in the first cavity. The light guide in two adjacent BLUs of the module defines a second cavity opposite the first cavity for receiving an adjacent heat conduction member of a prior adjacent light guide. The module is provided with a variable size with the BLUs assembled together to meet requirements.

  • Method and apparatus of automatically tuning output line rate and display controller provided with the same
    Patent number: 7034812
    Abstract: A method and apparatus for automatically tuning the output line rate thereof and a display controller provided with the same. The display controller of the present invention provides a display controller having a line buffer, an input means, an output means, a status detector, and an auto-tune control means. The input means is employed to write line data into the line buffer at an input line rate, and the output means is employed to read the written line data from the line buffer at an output line rate. The status detector is coupled to the input means and the output means for generating a status signal indicating whether the input line rate and the output line rate are unbalanced. The auto-tune control means is used to adjust the output line rate in response to the status signal so as to balance the input line rate and the output line rate.

  • Compact fluorescent lampholder
    Patent number: 7033220
    Abstract: A compact fluorescent lampholder includes a cap, a shell, an electric board and a base. The cap and the shell are combined together by hooking, and the electric board is combined with the base by plural pins, and then the electric board assembled together with the base is inserted in a hollow space of the shell. A compact fluorescent lamp (CFL) is to be inserted in a groove in the base. Then wires are connected properly between the electric board and electric power so as to light up a CFL fitted in the base. The shell is easily separated from the cap to fall down a little owing to some spare preset length of the wires so it is convenient to replace a CFL or to repair the socket.
