    • A CMOS tri-mode input buffer for generating three groups of binary codes at first and second output nodes in response to an input signal having three different voltage levels includes an output stage (20), first output buffer (22), a second output buffer (24), a first inptu circuit (26), and a second input circuit (28). The output stage (20) generates first and second output signals (Q1, Q2) at the respective first and second output noes (16, 18). The first output buffer is responsive to the first output signal (Q1) for generating a first buffered input signal (U1) which is CMOS logic compatible. The second output buffer (24) is responsive to the second output signal (Q2) for generating second buffered output signal (U2) which is CMOS logic compatible.

    • A vapor chamber includes a plate and a wick structure. The plate is provided therein with a working fluid, and the plate has a heated end and a condensed end. The wick structure comprises a first wick portion adhered to be opposite to the heated end, a second wick portion overlapping on the first wick portion, and a third wick portion adhered on the rest portion of a chamber. The aperture diameter of the first wick portion is larger than that of the second wick portion, or the aperture density of the first wick portion is smaller than that of the second wick portion. Therefore, the amount of working fluid attached to the second wick portion is smaller than of the first wick portion. As a result, after heated, the working fluid attached to the second wick portion will be vaporized more quickly, thereby increasing the efficiency of heat transfer and improving the heat-dissipating effect.
    • 蒸气室包括板和芯结构。 板中设置有工作流体,并且板具有加热端和冷凝端。 芯结构包括粘附到加热端的第一芯部,与第一芯部重叠的第二芯部,以及粘附在室的其余部分上的第三芯部。 第一灯芯部分的孔径大于第二灯芯部分的孔径直径,或者第一灯芯部分的孔径密度小于第二灯芯部分的开口密度。 因此,附着到第二芯部的工作流体的量比第一芯体部分小。 结果,加热后,附着于第二芯部的工作流体将更快地汽化,从而提高传热效率并提高散热效果。
