Abstract: A window or door casing includes two side sections, a header or top section and bottom section. The bottom section also has caps attached at either end. The trim casing is mountable on a window or door frame and is securely fastened to the side of the house ensuring a tight fit and finished appearance.

Abstract: A charge transfer device has a charge transfer region under charge transfer electrodes for stepwise conveying charge packets through potential wells to a floating diffusion region, and the charge transfer region has a boundary sub-region contracting toward the floating diffusion region, wherein the final potential well is created at a certain portion in said boundary sub-region close to the floating diffusion region so that each charge packet travels over a short distance, thereby enhancing a charge transfer efficiency.

Abstract: A bone graft material which comprises an expanded volume of a biocompatible material in convoluted form. Typically, the material has a volume increase of at least two fold, preferably five to fifteen fold.

Abstract: A comparator compares the signal voltage S (i, j) applied to the display element P(i, j) on a predetermined data electrode Xi on the scanning electrode Yj for the current display period and the signal voltage S(i, j+1) applied to the display element P(i, j+1) on the data electrode Xi on the scanning electrode Y (j+1) during the next display period. A controller controls a discharge of residual electric charges or a quantity of residual electric charges discharged from the data electrode Xi during a blanking period immediately before the next display period depending on the comparison result by the comparator.
