    • A termination for silicon superjunction VDMOSFET comprises heavily doped N-type silicon substrate which also works as drain region; drain metal is disposed on the back surface of the heavily doped N-type silicon substrate; an N-type silicon epitaxial layer is disposed on the heavily doped N-type silicon substrate; P-type silicon columns and N-type silicon columns are formed in the N-type silicon epitaxial layer, alternately arranged; a continuous silicon oxide layer is disposed on a part of silicon surface in the termination; structures that block the drift of mobile ions (several discontinuous silicon oxide layers arranged at intervals) are disposed on the other part of silicon surface in the termination. The structures that block the drift of mobile ions disposed in the termination region are able to effectively prevent movement of the mobile ions and improve the capability of the power device against the contamination induced by the mobile ions.
    • 硅超结VDMOSFET的终端包括也用作漏极区的重掺杂N型硅衬底; 漏极金属配置在重掺杂N型硅衬底的背表面上; 在重掺杂的N型硅衬底上设置N型硅外延层; 交替布置在N型硅外延层中形成P型硅柱和N型硅柱; 连续的氧化硅层设置在终端的硅表面的一部分上; 阻止移动离子漂移的结构(间隔布置的几个不连续的氧化硅层)设置在终端的硅表面的另一部分上。 阻止设置在终端区域中的移动离子的漂移的结构能够有效地防止移动离子的移动,并提高功率器件抵抗由移动离子引起的污染的能力。

    • A system for synchronizing sender sliding windows and receiver sliding windows employed in wireless packet communication is provided. The sender sliding window buffers outgoing packets to be sent to a receiver that employs a receiver sliding window to buffer incoming packets. A sender window manager manages the sender sliding window through positive acknowledgement, negative acknowledgement and/or timeout processing to facilitate synchronizing the sender sliding window with the receiver sliding window without employing synchronization messages or master/slave control. Similarly, a receiver window manager manages the receiver sliding window through sequence number analysis to facilitate synchronizing the receiver sliding window with the sender sliding window without employing synchronization messages or master/slave control.
    • 提供了一种用于同步无线分组通信中使用的发送器滑动窗口和接收器滑动窗口的系统。 发送者滑动窗口缓冲要发送到使用接收器滑动窗口缓冲传入数据包的接收器的输出数据包。 发送者窗口管理器通过肯定确认,否定确认和/或超时处理来管理发送者滑动窗口,以便于不使用同步消息或主/从控制同步发送者滑动窗口与接收器滑动窗口。 类似地,接收机窗口管理器通过序列号分析来管理接收器滑动窗口,以便于使接收器滑动窗口与发送者滑动窗口同步而不使用同步消息或主/从控制。

    • The present invention refers to a method being easy to recover metals including nickel and aluminum from waste aluminum catalysts, thereby entirely promoting the recovering rate. Said method comprises: preparing and roasting a waste aluminum catalyst with sodium salts, and then obtaining a first solution comprising vanadium and molybdenum, and a dreg comprising nickel and aluminum through leaching and filtrating; collecting and mixing the dreg with alkali powders to obtain a mixture of the dreg and alkali powders, roasting the mixture at 300 to 1000° C. with aluminum in the dreg reacting with hydroxyl generated from the roasting of mixture and further generating aluminum hydroxide, and then obtaining a second solution comprising aluminum and a concentrate having nickel through another leaching and filtrating; and recovering aluminum from the second solution and recovering nickel from the concentrate.
