Abstract: The coater apparatus enclosure encloses the entire die of a coating apparatus includes an enclosure structure, a saturation station which saturates a supply gas with solvent, a device which supplies solvent-saturated gas to the enclosure to continuously purge the enclosure, and a device which controls the gas flow to the enclosure. The saturation station could include a heated jacketed vessel and a porous metal bubbler, or it could include a series of heat exchangers. No streaks can form due to coating fluid drying on the die lip because the gas supplied to the die enclosure is saturated with the solvent.

Abstract: A fixture and method for use in deposition of a material over a substrate make use of an apparatus for actively heating and cooling the substrate during the deposition process. The active heating and cooling structure enables careful control of the temperature of the substrate, and can provide rapid temperature adjustment in response to temperature variation. The fixture and method are thereby capable of accelerating the overall deposition process. The fixture and method also make use of structure for reducing warpage in the fixture during the deposition process due to thermal gradients. By reducing the susceptibility of the fixture to warpage and providing improved temperature control, the fixture and method enable fabrication of layers with more consistent characteristics.

Abstract: A vent plug includes a thermophastic tubular body for insertion in an aperture in the lid of a battery. The vent plug has at its upper end an integral lid with a gas venting aperture formed therein. A removable insert is secured within the tubular body and defines a tortuous gas venting path. The insert and the body are constructed to define a space with which the gas venting aperture and the gas venting path communicate, the space accommodating a porous flame retarding body.
