摘要:
A method of film fabrication is taught that uses a coating and drying apparatus to fabricate resin films suitable for optical applications. In particular, resin films are prepared by simultaneous application of multiple liquid layers to a moving carrier substrate having low surface energy. After solvent removal, the resin films are peeled from the sacrificial carrier substrate. Films prepared by the current invention exhibit good dimensional stability and low out-of-plane retardation.

摘要:
The invention generally relates to polymer films used as protective cover sheets for polarizer plates, a method for producing polarizing plates, and a Liquid Crystal Display employing the same. More particularly, the invention relates to a cover sheet composite having a removable, carrier substrate and a cover sheet comprising a low birefringence polymer film and a layer that promotes adhesion to polyvinyl alcohol on the same side of the carrier substrate as the low birefringence polymer film. The guarded cover sheet of the invention is less susceptible to defects due to dirt and abrasion during the manufacture of the cover sheet and polarizer plates. In addition, the cover sheet has excellent adhesion to polyvinyl alcohol-containing dichroic films and eliminates the need to alkali treat the cover sheet prior to lamination to the dichroic films.

An audio amplifier is provided having a compressor with an automatically-adjustable compressor. Compression is linked to the volume control in an inverse relationship whereby, when the volume is reduced, the compression ratio is increased to boost the listening level of quieter passages in the source material. Conversely, when the volume is increased, the compression ratio is decreased. The compression control may be physically connected to the volume control, such as in a dual-potentiometer, or may be coupled electronically, such as with a digital signal processor. An effects level control may be included to allow a listener to increase or decrease the effect of the compression by applying a multiplier to the compression ratio. An ambient noise detector may also be included such that compression is increased as ambient noise increases or exceeds a predetermined level.

The present invention provides a planographic printing element suitable to receive and bond with a subsequently applied hydrophilic layer comprises a substrate layer, such as polyester film or paper, having coated thereon an adhesion layer, said adhesion layer comprising a polymer having a glass transition temperature of less than 15 C and containing functional groups such as hydroxyl, epoxy or glycidyl groups capable of reacting with the hydrophilic layer. The polymer may be a terpolymer of a hydroxyalkyl methacrylate, an alkyl acrylate and an aminoalkyl methacrylate. The polymer may be mixed with gelatin and the mixture applied to the substrate as a coating. The hydrophilic layer, which may comprise metal oxide particles, such as aluminium oxide and/or titanium dioxide particles in a sodium silicate binder, is subsequently applied as a coating to the adhesion layer.
