  • Publication number: 20100021560
    Abstract: A silver-supporting bamboo charcoal (BC/Ag) comprising silver in different weight ratio of 26% (BC/Ag-1), 29% (BC/Ag-2), 34% (BC/Ag-3), 48% (BC/Ag-4), 57% (BC/Ag-5), or 75% (BC/Ag-6). The BC powders (particle size<10 ?m, Taiwan Paiho) are activated with surfactant sodium alginate under stirred for 1 h. The as-prepared BC powders (2 g) are immersed into 100 mL of biamminesilver nitrate ([Ag(NH3)2]NO3) solutions, which are formed by adding 28 wt. % aqueous ammonia into AgNO3 solution at room temperature. After stirring for 1 h, dilute aqueous solutions of hydrazine monohydrate are separately prepared and introduced to the BC-AgNO3 solutions in appropriate quantities (molar ratio 1:1 with respect to silver nitrate) by a syringe. Stirring is continued under inert atmosphere at room temperature for another 4 h. The BC/Ag particles are separated and washed with deionized water and ethanol, then dried in vacuum at 60° C. for overnight.

  • Patent number: 7563625
    Abstract: Methods for fabricating a semiconductor light-emitting diode (LED) device with increased light extraction are provided. The method generally includes applying a mask to a surface of an LED wafer, etching the surface of the LED wafer such that etched pits are formed in the surface, removing the mask, and roughening or texturing the surface of the LED wafer including the etched pits. In this manner, the surface area of the LED device may be increased when compared to a conventional LED device, and less emitted light may experience total internal reflection (TIR) according to Snell's law, thereby leading to increased light extraction.

  • Publication number: 20090093075
    Abstract: A method for the separation of multiple dies during semiconductor fabrication is described. On an upper surface of a semiconductor wafer containing multiple dies, metal layers are deposited everywhere except where a block of stop electroplating material exists. The stop electroplating material is obliterated, and a barrier layer is formed above the entire remaining structure. A sacrificial metal element is added above the barrier layer, and then the substrate is removed. After the semiconductor material between the individual dies is eradicated, any desired bonding pads and patterned circuitry are added to the semiconductor surface opposite the sacrificial metal element, a passivation layer is added to this surface, and then the sacrificial metal element is removed. Tape is added to the now exposed barrier layer, the passivation layer is removed, the resulting structure is flipped over, and the tape is expanded to separate the individual dies.

  • Publication number: 20090032417
    Abstract: A lockable storage container for disc-like information storage media is disclosed. The storage container has a cover and a disc holder. The cover of the storage container has a notch structure formed on the inner surface at an open-side thereof. The disc holder has at least a projection element disposed around the annular sidewall. The storage container is locked by conjugating the projection element and the corresponding notch structure. In order to separate the cover and the disc holder, the projection element has to be broken. Accordingly, the storage container is lockable and prevents the disc-like storage media disposed therein from being stolen.

  • Patent number: 7448762
    Abstract: A sideview mirror includes multiple parts, wherein the mirror body, the washer, the spring, the support member, the bearing, the rotation member, and the mounting member are combined to form a window corner type sideview mirror, while the mirror body, the washer, the spring, the support member, and the mounting member are combined to form a car side body type sideview mirror. Thus, the window corner type sideview mirror only needs to provide the fixing member additionally to replace the bearing, the rotation member, and the mounting member to form the car side body type sideview mirror, so that the sideview mirror is both available for a window corner type sideview mirror and a car side body type sideview mirror.
