A patient repositioning system includes a drive unit, which is adapted for mounting to a head end of a patient support, and a clamp assembly. The process includes providing a semiconductor substrate having a plurality of isolation features between a PFET region and a NFET region, and forming gate stacks on the semiconductor substrate. An operator defines a size, a finishing color, a material, etc. Additionally upon insertion, the cartridge shutter releasably engages with the developer, and the cartridge releasably engages with the developer shutter. 1 \u03bcm, the ferromagnetic powder contained in the magnetic layer is an acicular ferromagnetic alloy powder having the mean major axis length equal to or less than 0. The frame members comprise outer frames that are arranged so as to form outline of each face of the solid shape, and corner parts that are arranged at the corners of the sold shape and connect adjacent outer frames.
