摘要： A screwdriver with rotating lever according to this invention includes a screwdriver head. The screwdriver head includes a rod, an operation portion formed at a first end of the rod, and a fixing portion formed at a second end of the rod. The rod is a polygonal prism and extends spirally from the operation portion to the fixing portion to form a spiral curved surface. With the rod formed with the spiral curved surface, when the screwdriver with rotating lever operates, the rod is of higher strength and may bear stronger torsion stress for increasing the service life of the screwdriver.

摘要： A socket wrench having multiple driving heads includes a triangular star-shape handle which consists of an upper and a lower shell. The triangular portions of the handle have respectively a protrusive driving portion. Two neighboring driving portions are connected by a side wall formed in an arched shape concaved inwards. Each driving portion holds a driving bar having a coupling head on an outer side and a ratchet on an inner side inside. A clamping box is provided that includes an upper and a lower deck in the interior center of the handle and has three pairs of detent plates in the middle to control turning direction of the ratchet. A rotary knob is provided having an actuation bar beneath to move the detent plates. Thus a plurality of driving bars which hold the coupling heads of different shapes and sizes can be held in the handle. The socket wrench thus formed can be grasped easily and change of driving direction can be accomplished rapidly.

摘要： A plurality of N-doped strip portions are formed alternating with a plurality of P-doped regions. When a voltage is applied to the N-doped strip portions, a capacitance is created between the N-doped strip portions and the P-doped strip portions. A capacitance is also created between the N-doped strip portions and the underlying epitaxial silicon layer. A larger interface area between N-doped and P-doped regions generally increases the capacitance. By providing the N-doped strip portions, as opposed to a continuous N-doped region, the combined interface area between the N-doped strip portions and the underlying epitaxial silicon layer is reduced. However, more interface area is provided between the N-doped strip portions and the P-doped strip portions. A circuit simulation indicates that junction capacitance per unit peripheral length is 0.41 fF/μm, while the junction capacitance per unit area is 0.19 fF/μm^2. Junction capacitance per unit peripheral length thus scales faster than junction capacitance per unit area.

摘要翻译： 多个N掺杂条带部分与多个P掺杂区域交替地形成。 当向N掺杂条带部分施加电压时，在N掺杂条带部分和P掺杂条带部分之间产生电容。 在N掺杂条带部分和下面的外延硅层之间也产生电容。 N掺杂和P掺杂区域之间的较大接口面积通常增加电容。 通过提供N掺杂条带部分，与连续的N掺杂区域相反，N掺杂条带部分和下面的外延硅层之间的组合界面面积减小。 然而，在N掺杂条带部分和P掺杂条带部分之间提供更多的界面面积。 电路仿真表明，每单位周长的结电容为0.41 fF / mum，而单位面积的结电容为0.19 fF / m ^ ^ 2。 每单位外围长度的结电容因此比单位面积的结电容快。
