    • A conical point sharpener for sharpening conical shaped points such as fishhooks, needles, surgical instruments includes a handle, a mandril with an abrasive material coating fixed to one end of said handle, a drive spindle, wherein said drive spindle is movably attached to said handle and envelops said mandril, an outwardly protruding tapered opening on said drive spindle, and a precision point alignment nest, formed between said abrasive material coating on said mandril and said drive spindle, such that when the conical point to be sharpened is placed in said outwardly protruding tapered opening of said drive spindle, the item to be sharpened is located in said precision point alignment nest and the point of the item is touching said abrasive material coating on said mandril so that the user can then rotate said drive spindle while holding the item to be sharpened, thereby conically sharpening the point as the item to be sharpened rotates around said mandril.
    • 一种锥形点磨刀器,用于磨削圆锥形点,例如鱼钩,针,外科器械,包括手柄,固定到所述手柄的一端的磨料涂层的心轴,驱动心轴,其中所述驱动心轴可移动地连接到所述手柄 并且在所述驱动主轴上包围所述的中心锥体,一个向外突出的锥形开口,以及形成在所述心轴上的所述研磨材料涂层和所述驱动心轴之间的精密点对准座,使得当要被削尖的锥形点被放置在所述向外 所述驱动轴的突出的锥形开口,待磨削的物品位于所述精密点对准座中,并且物品的点接触所述心轴上的所述磨料涂层,使得使用者可以在保持物品的同时旋转所述驱动主轴 被削尖,从而当要削尖的物品围绕所述心轴旋转时锥形磨锐。

    • A set of gate sizes for a netlist having a plurality of gates wherein for each of the gates a number of discrete gate sizes is available is selected such that the selection minimizes worst slack in the netlist. A current gate size for each gate is selected and an a current weight assigned to each one of the timing edges in the netlist. A new gate size is selected for each one of the gates from one of the current gate size and second one of the available gates sizes wherein such selection of each new gate size minimizes a sum of weighted delays obtained over all timing edges. The minimum sum of weighted delays is obtained from a min-cut in a timing flow graph. The results of the min-cut are used in the next iteration and re-iterating occurs until an exit criteria is determined.
    • 具有多个门的网表的一组门尺寸,其中对于每个门,选择多个离散门尺寸是可用的,使得选择使网表中最差的松弛最小化。 选择每个门的当前门尺寸和分配给网表中的每个时序边缘的当前权重。 从当前栅极尺寸和可用栅极尺寸中的一个选择栅极大小,其中每个新栅极尺寸的这种选择使得在所有定时边缘上获得的加权延迟之和最小化。 加权延迟的最小总和是从定时流程图中的最小值获得的。 最小切割的结果在下一次迭代中使用,并且重新迭代发生,直到确定退出标准。
