    • An ink jet printer with a roll of paper stored within an imaging drum. The paper through a longitudinal opening in the drum to the outside, passes around the drum, where it is held in place during the imaging process, and then ejected from the drum to the desired length and cut off by a cutter that extends the full width of the paper. While the imaged sheet is being ejected from the drum, the next length of paper is drawn from the interior of the drum and around the outside of the drum in position for the next imaging operation. The length of paper that remains projecting from the drum after the imaged paper has been cut off is then withdrawn into the interior of the drum through the longitudinal opening in the drum surface until only a short stub, which will not interfere with the subsequent imaging operation, remains protruding from the drum. Precise movement of the paper is under the control of a counter that is responsive to the paper movement. This counter movement also provides an indication in the event the paper jams and warns when the supply of paper within the drum is nearing its end. The entire operation is automatic under the control of a central processor unit.
    • 一种具有存储在成像鼓内的一卷纸的喷墨打印机。 纸张通过鼓中的纵向开口到外部,绕过滚筒,在成像过程中将其保持在适当的位置,然后从滚筒中排出到期望的长度,并通过延伸整个宽度的切割器切断 的论文。 当成像的片材从鼓中排出时,下一个长度的纸从鼓的内部和围绕滚筒外部的位置被抽出以进行下一次成像操作。 在成像纸已经被切断之后从滚筒中保持的纸张的长度然后通过滚筒表面中的纵向开口被撤回到滚筒的内部,直到只有短短的短截线,这不会干扰随后的成像操作 ,保持从滚筒突出。 纸张的精确运动受到响应纸张移动的计数器的控制。 这种柜台运动还提供了当纸张在滚筒内供应正在接近尾端时卡纸并警告的情况。 整个操作在中央处理器单元的控制下是自动的。

    • An LED light string employs a plurality of LEDs wired in block series-parallel, where the one or more series blocks, each driven at the same input voltage or rectified AC input voltage as the source voltage (110 VAC or 220 VAC), are coupled in parallel. This voltage matching requirement for direct AC drive places fundamental restrictions on the number of diodes on each diode series block, depending on the types of diodes used. The same method that apply to matching the sum of the LED lamps (VAC values) to the AC input, or applied voltage in an AC circuit apply to matching the sum of the LED lamps (VP values) to the full-wave or half-wave rectified AC (VP) voltage applied. Filtering capacitors may also be employed.
    • LED灯串使用串联并联的多个LED,其中以与源电压(110VAC或220VAC)相同的输入电压或整流的AC输入电压驱动的一个或多个串联块被耦合 在平行下。 根据所使用的二极管的类型,直流交流驱动器的这种电压匹配要求对每个二极管串联模块上的二极管数量做出了基本的限制。 适用于将LED灯(VAC值)的总和与AC输入或AC电路中的施加电压进行匹配的相同方法适用于将LED灯(VP值)的总和与全波或半波 波形整流AC(VP)电压。 也可以使用滤波电容器。
