An a-Si film formed on an insulating substrate is irradiated with a laser to obtain a p-Si film, which is then exposed to an oxidation atmosphere to form a surface oxide film. Movement of the disc from an expanded to a non-expanded condition causes water in the launch tank to drive the turbine to drive the pump inducer to pump water from the water inlet conduit to the impulse tank and thence to the launch tube to effect launch of a missile therein. The second plate has a central aperture dimensioned to receive the end of the roller blind. A rotatable component is mounted to the first body and adapted for rotatable movement to engage the length of hair within the internal chamber and wrap a segment of the hair about the elongate member. Moreover, a second sacrificial layer is formed over the first sacrificial layer inside the second area and the third area. Profile data from a source is converted to an intermediate color space upon entry into the platform at a choke point.
