Abstract: An ellipsometer measures/monitors the change in polarization of light upon reflection from a wafer sample. The temperature of the wafer substrate surface and the film thickness are then simultaneously determined in situ using ellipsometry where the true wafer temperature is determined in real-time by the computer from a calculation based on the known temperature dependence of the refractive index of the wafer. The power output to the lamps is then adjusted accordingly to raise or lower the wafer temperature within the apparatus. This process continues automatically to maintain the desired temperature and film growth rate until the desired film thickness is achieved.

A cementitious material fills the cavity so as to form the edge joint as well as the protected outer corner thereof.

Abstract: A rotary arm sewage treatment bed has its rotary arms driven by an electrical drive system. The drive system comprises a driving ring (7) to which the arms are secured. The drive ring is driven by a friction belt (8), from a drive wheel (10). The drive wheel (10) is mounted on a pivoted carriage (18). A compressor (30) operates a piston/cylinder (36)/(34). In normal use, the piston (36) acts on the carriage (18) to cause tensioning of the belt (8), and thus enable drive. In the event of a supply failure, the piston is retracted by a return spring and the drive is disengaged, the carriage being pivoted such that the drive wheel is no longer in a position to tension the belt (8). The arms are then free to rotate under the reaction force of the sewage emitted, until the power supply is restored.
