  • Patent number: 8005125
    Abstract: The present invention provides a fabrication method of coaxial line laser diodes and a coaxial lighting optical fiber which disperses and guides uniform emission of light from a coaxial line laser diode. The line coaxial laser diode can be extended at a greater length to generate more spontaneous emission photons which are emitted from an elongated tubular active layer. The active layer has a uniform built-in electric field to distribute uniform current therein to get higher quantum efficiency. The length of the coaxial laser diode can be increased through a VLSED method. A longer laser ingot can be produced and cut to a large number of coaxial laser diodes. This method can reduce the waste of cutting in the wafer process and get larger lighting areas. Both the coaxial line laser diode and the coaxial lighting optical fiber can be coupled to form a high efficiency white-emitting luminescence device.

  • Publication number: 20110139700
    Abstract: A collection process for precipitated powder substance is mainly for storing toxic or highly radioactive powder or dust in air and involves collection operation in water or other liquid to collect powder insoluble to the liquid and heavier than the liquid. To be suitable for underwater operation, a powder precipitation bag is provided with an innovative powder collection can at its bottom. New powder collection can has a mesh filter in its bottom and two-stage structure. After completion of powder collection, the collection can is pulled up from the water and dried to reduce powder volume and form powder lumps. Then, the top half is removed, so the collection can is fully filled with powder lumps. The newly designed powder can increases storage efficiency and reduces waste of space by accommodating more powder lumps than traditional powder can. With the same total amount of powder, the new powder can enables fewer number of storage cans.

  • Publication number: 20110024364
    Abstract: A filtration separation method for waste resin containing highly radioactive uranium powder and device thereof is mainly used for the waste resin after water treatment process in a nuclear facility. The uranium powder contained in the waste resin is highly radioactive. Thus, prior to the treatment of the waste resin, it is necessary to filter and separate the highly radioactive uranium powder to reduce the radioactivity. It is to put the uranium powder containing waste resin into an underwater holding tank and withdraw the waste resin by an underwater pump into a uranium powder filtration box. Then the uranium powder filtration box is lifted by a hoist to move to an underwater ultrasonic cleaner. High-pressure water flushing is applied and followed by underwater ultrasonic cleaning. Then the cleaning water (containing precipitated uranium powder) from the ultrasonic cleaner is drained to uranium powder collection device.

  • Publication number: 20100089448
    Abstract: A coaxial solar cell forces an exposed annular light receiving layers of a constant thickness to directly receive projection of light excitedly to generate pairs of electrons and holes that are driven by radial built-in electronic field formed on a PN junction to travel by the same distance paths to coaxial inner and outer electrodes. The photons directly enter an exposed drift region. The excited pairs of electrons and holes are separated by the even built-in electronic field to output current. Loss caused by crowding and recombination of diffusion current can be prevented. Photoelectric conversion efficiency improves without losing photon energy of short wavelengths projecting to the surface. The linear coaxial solar cell is fabricated by forming coaxial and annular semiconductor layers or compound films through deposition. Thus, it can be continuously fabricated by extending its length and mass production to reduce costs.
