    • A multi-functional calendar structure includes a calendar made up of a set of upper and lower layers wherein the upper layer has week elements, day elements, and month elements respectively marked at the front face thereon, and a plurality of empty elements for recording important occasions or favorable/forbidden events in the month sequentially arranged at the bottom of the front face thereon. Each of the day and empty elements is provided with a set of top and bottom dotted tearing lines, a set of transversely U-shaped left and right cut areas disposed at both adjacent edges of the top/bottom dotted tearing lines thereof, an oblique cut opening defining the lower section of the left cut area thereof, and an adhesive portion properly coated at the reverse face thereon and limited within the left/right cut areas thereof. The lower layer is also provided with identical day and empty elements in corresponding positions relative to that of the upper layer thereof. Therefore, the day/empty elements with memo recorded thereon can be easily detached from the upper layer to serve as notes for easy carry outside, while identical copies of the memo can be left on the corresponding day/empty elements of the lower layer for further reference by other people. Besides, via the adhesive portions thereof, the note can be easily attached to an obvious position in cars or the offices as a reminder, efficiently providing a multi-functional calendar thereby.
    • 多功能日历结构包括由一组上层和下层组成的日历,其中上层具有分别在其正面上标记的周元素,日元元素和月份元素,以及用于记录重要的多个空元素 在其前面的底部依次配置的月份或有利/禁止的事件。 白天和空白元素中的每一个都设置有一组顶部和底部虚线撕裂线,一组横向U形的左右切割区域,其设置在其顶部/底部虚线撕裂线的两个相邻边缘处,倾斜切割 限定其左切割区域的下部的开口,以及在其反面上适当地涂覆并限制在其左/右切割区域内的粘合剂部分。 下层还具有相对于其上层的相应位置的相同的日元和空元件。 因此,在其上记录有备忘录的日/空元件可以容易地从上层分离,以便作为便于携带的注释,同时备忘录的相同副本可以留在下层的相应日/空元件上用于进一步 参考其他人。 此外,通过其粘合部分,可以将音符作为提醒容易地附接到汽车或办公室中的明显位置,从而有效地提供多功能日历。

    • A controller for a power converter includes a clamping circuit, a switching circuit and a pulse generator. The clamping circuit is coupled to an input terminal of the controller for detecting a detection signal from a transformer. The switching circuit generates a switching signal to switch the transformer in response to the detection signal for regulating the power converter. A maximum level of the detection signal is clamped to be under a level of a threshold voltage during an off-period of the switching signal. Since the maximum level of the detection signal is clamped and the oscillating energy of the reflected signal is discharged, the speed of detecting the detection signal is increased. Therefore, the regulation of the primary-side controlled power converter can be improved accordingly.
    • 一种用于功率转换器的控制器包括钳位电路,开关电路和脉冲发生器。 钳位电路耦合到控制器的输入端,用于检测来自变压器的检测信号。 开关电路响应于用于调节功率转换器的检测信号产生开关信号以切换变压器。 检测信号的最大电平在切换信号的截止周期期间被钳位在阈值电压的电平以下。 由于检测信号的最大电平被钳位并且反射信号的振荡能量被放电,所以检测信号的速度增加。 因此,可以相应地改善初级侧受控功率转换器的调节。

    • A control circuit of a power converter according to the present invention comprises an output circuit, at least one input circuit and an input-voltage detection circuit. The output circuit generates a switching signal for regulating an output of the power converter in response to at least one feedback signal. The switching signal is coupled to switch a transformer of the power converter. The input circuit samples at least one input signal for generating the feedback signal. The input signal is correlated to the output of the power converter. The input-voltage detection circuit generates an input-voltage signal in response to the level of the an input voltage of the power converter. The input circuit will not sample the input signal when the input-voltage signal is lower than a threshold. The control circuit can eliminate the need of the input capacitor for improving the reliability of the power converter.
