  • Publication number: 20240226929
    Abstract: An annular airflow regulating apparatus includes a cup-shaped element and an adjustment element. The cup-shaped element has a bowl and a bottom, integrated to form a first chamber. The bottom has a tapered channel parallel to an axis and penetrating through the bottom. A ring-shaped groove is disposed between the tapered channel and the bottom. The ring-shaped groove has an annular plane perpendicular to the axis. The adjustment element, having a tapered portion and second holes, is movably disposed in the cup-shaped element. The tapered portion protrudes into the tapered channel A tapered annular gap is formed between the tapered portion and the tapered channel. When the adjustment element is moved with respect to the cup-shaped element, a width of the tapered annular gap is varied, and thereupon a flow rate and velocity of the process gas would be varied accordingly.

  • Patent number: 8715536
    Abstract: An electrically conductive material includes a plurality of nanowires and a plurality of nanoconnectors. The ratio by weight of the plurality of nanowires to the plurality of nanoconnectors is in a range of from 1:9 to 9:1. Nanoconnectors can be heated by thermal energy or light energy so that the nanoconnectors can be closely interconnected to each other and to nanowires, resulting in significant increase of the electrical conductivity of the electrically conductive material.

  • Publication number: 20110094573
    Abstract: A solar cell and a method for fabricating the same are provided. The solar cell includes a first electrode, a second electrode, a photoelectric conversion layer and a non-conductive reflector. The first electrode including a nano-metal transparent conductive layer is disposed on a transparent substrate. The nano-metal transparent conductive layer substantially contacts with the photoelectric conversion layer. The second electrode is disposed between the photoelectric conversion layer and the transparent substrate. The photoelectric conversion layer is disposed between the first and the second electrodes. The non-conductive reflector is disposed on the first electrode.
