Abstract: In polishing a substrate having a layer of GST disposed over an underlying layer, during polishing, a non-polarized light beam is directed onto the layer of GST. The non-polarized light beam reflects from the first substrate to generate a reflected light beam having an infra-red component. A sequence of measurements of intensity of the infra-red component of the reflected light beam are generated, and, in a processor, a time at which the sequence of measurements exhibits a predefined feature is determined.

Abstract: In a hydraulic screw pump, a sealing element for the peripheral edge of the rotary screw. The sealing element is formed with a channel along its length to fit over this edge of the rotary screw. The channel may be varied in depth to adjust the gap between the rotary screw and a water-carrying trough for the pump. The width of the channel may also be adjusted to accommodate rotary screws of varying thicknesses. The sealing element, thus, retains the desired width of the gap even though the edges of the rotary screw are chipped or worn away.

Each vane has a valve opening therethrough, and a flap valve pivotally mounted on the vane and selectively operable to close the valve opening. The improvement includes a dam-like shield at the outer end portion of the vane. This shield is provided with one or more control openings aligned with the flap valve. As the vane approaches the standing wave ahead of the turbine, water passes through the control openings to close the aligned flap valves, thereby insuring that the pressure of the flow will be applied to the entire trailing surface of the vane.
