A process and associated apparatus used to prepare a thermoplastic composite from a plurality of plies of thermoplastic resin prepregs. The prepregs are formed into a composite structure under two chambers; a rigid outer chamber (of any convenient size or shape) and a second flexible inner chamber containing a prepreg lay-up. The absolute pressures are reduced concurrently in a stepwise method in both chambers. This concurrent, stepped pressure reduction is accomplished at a rate which prevents the vacuum bag from moving far from the prepregs, and prevents wrinkles from forming in the prepregs. Pinching off the diffusion paths required for the removal of unwanted gases is eliminated. The lay-up is then heated and the absolute pressure in the outer rigid chamber is increased. This pressure constrains the flexible inner chamber during out-gassing of the thermoplastic resin, preventing wrinkles from forming in the prepregs. The absolute pressure in the outer rigid chamber is increased to atmospheric pressure or greater causing the prepregs to consolidate. A low absolute pressure is maintained in the flexible inner chamber. The temperature is then increased to the cure temperature of the resin and held for a time sufficient for the resin to cure. The resulting consolidated thermoplastic resin is substantially void free and detectable wrinkles are absent.

A flexible protective padding material is described and comprises an array of resilient multilayered elements or blocks which have generally planar top and bottom surfaces and each of which have at least two layers which include a first layer bonded to an outer second layer.

A gas bag in which an orifice is opened or closed with the aid of a control band as soon as the gas bag has reached a predetermined state of deployment. One end of the control band is fastened to a gas bag envelope in the region of the orifice. The control band is connected at its other end to the gas bag envelope so that, when the predetermined state of deployment is reached, the control band slips into the gas bag envelope so that the orifice is closed by the slipped-in region of the gas bag envelope by the internal pressure of the gas bag, or the control band slips out of the gas bag envelope so that the previously closed orifice is opened.

In a liquid crystal display device according to the present invention, an upper end portion of a lamp housing is fixed on a main supporter so that the lamp housing can be made to face a side edge of a light guide. Light that can cause bright lines is eliminated or minimized through absorption or scattering by a main supporter. The main supporter is also thermally insulating and is placed between the lamp housing and a liquid crystal panel. Further, a thermally conducting bottom cover is placed under the backlight. Therefore, heat generated from the lamp is effectively channeled away from the light guide to prevent liquid crystal panel deterioration. Still further, although the upper and lower surfaces of the light guide is tightly fit between the lamp housing and the main supporter, wrinkles on a sheet reflector are prevented because the sheet reflector is not stacked between the lamp housing and a lower surface of the light guide.
