    • A power factor correction power supply unit for correcting a power factor includes a switching device, an input voltage detection circuit, an output voltage detection circuit, an error amplifier for outputting an error signal obtained by amplifying a difference between an output voltage detection signal and a reference voltage, an ON width generation circuit for generating an ON time width, an OFF width generation circuit for generating an OFF time width of the switching device, and a switching device driving circuit. The drive circuit conducts an ON/OFF control over the switching device upon receiving a turn-on timing signal for turning on the switching device as soon as the OFF time width is terminated and upon receiving a turn-off timing signal for turning off the switching device as soon as the ON time width is terminated.

    • A nonvolatile memory cell includes a substrate comprising a source, drain, and channel between the source and the drain. A tunnel dielectric layer overlies the channel, and a localized charge storage layer is disposed between the tunnel dielectric layer and a control dielectric layer. A gate electrode has a first surface adjacent to the control dielectric layer, and the first surface includes a midsection and two edge portions. According to one embodiment, the midsection defines a plane, and at least one edge portion extends away from the plane. Preferably, the edge portion extending away from the plane converges toward an opposing second surface of the gate electrode. According to another embodiment, the gate electrode of the nonvolatile memory cell includes a first sublayer and a second sublayer of a different width on the first sublayer.

    • The embodiment of the present invention provides a method for establishing a route, which includes searching a target node by a node from a first level node group according to first level route information, returning to query a result or data saved by the target node if the target node is found, otherwise executing the following step; searching a target node by the node from a higher level node group according to higher level route information, returning to query a result or the data saved by the target node if the target node is found, otherwise repeating the step. Through the hierarchical communication system, most of the flows of daily service operations in the communication network are limited within a small region, thereby preventing from excessively occupying the band width of a backbone network being originally not wide enough.
    • 本发明的实施例提供了一种建立路由的方法,其包括根据第一级路由信息从第一级节点组中的节点搜索目标节点,返回查询结果或由目标节点保存的数据,如果 找到目标节点,否则执行以下步骤; 根据较高级别的路由信息​​从上一级节点组中的节点搜索目标节点,如果找到目标节点,返回查询结果或目标节点保存的数据,否则重复该步骤。 通过分层通信系统,通信网络中日常业务运行的大部分流量在小区域内受到限制,从而防止过度占据骨干网络的带宽原本不够宽。
