Abstract: An IC device includes first through third rows of fin field-effect transistors (FinFETs), wherein the second row is between and adjacent to each of the first and third rows, the FinFETs of the first row are one of an n-type or p-type, the FinFETs of the second and third rows are the other of the n-type or p-type, the FinFETs of the first and third rows include a first total number of fins, and the FinFETs of the second row include a second total number of fins one greater or fewer than the first total number of fins.

Abstract: A cutter head comprising a plurality of coaxially disposed transmission shafts including a central transmission shaft and at least two tubular transmission shafts with each shaft having a cutting member, the shafts being driven independently with one another and any two radially adjacent shafts being driven to rotate in opposite directions, wherein diameters of the shafts are determined in such a manner that a sum of cutting areas covered by the cutting members of the shafts rotating in one direction is substantially equal to a sum of the cutting areas covered by cutting members of the shafts rotating in the opposite direction.

Abstract: A saddle anchorage in which the direction of the prestress is not perpendicular to the compression surface of the concrete structure. The anchorage comprises a saddle including a rectangular metal plate provided with two parallel locking portions defining a hollow portion therebetween, a bottom portion for the hollow portion, a first rib plate, a second rib plate, a third rib plate having a first opening, a hollow cylindrical sleeve, a plurality of U-shaped first reinforcing steel bars, and a plurality of U-shaped second reinforcing steel bars; and a rider for fixing an anchor head including two triangular side plates provided with locking portions, a rectangular top plate, and a front plate having a second opening.
