  • Hydrogen storage medium
    Publication number: 20040142203
    Abstract: The vapor deposition of metal, metal alloy, metallic compound as a thin film onto a continuous web provides a metal hydride based hydrogen storage medium, including a component for fuel cells. After or before such a single or multilayer thin film is used as or converted to metal hydride, the web is formed into the active component in a hydrogen gas storage vessel or the or an electrode layer and support for a battery or fuel cell.

  • Apparatus and method for depositing environmentally sensitive thin film materials
    Publication number: 20040142104
    Abstract: An apparatus and method for depositing thin materials that are sensitive to the environment outside the coating chamber deploys a sealable canister as a take up roll in a roll-to-roll vacuum coating apparatus. A front slot in the canister receives web or film during coating, but is sealed when the coating process is completed, but before the chamber is vented to the atmosphere.

  • Gas injector for plasma enhanced chemical vapor deposition
    Patent number: 6116185
    Abstract: The use of a gas injector including a dielectric material around the ports has an advantage when used with plasma enhanced chemical vapor deposition in that a plasma torch will not be formed at the gas injector and the gases will not dissociate prematurely. This adds to the quality of the coatings and allows the system to be used at higher amperage and thus improved line speeds. The use of a dielectric plug at the ports allows the ports to be easily serviced and replaced.

  • Unwinding of plastic film in the presence of a plasma
    Patent number: 5935662
    Abstract: Supplying gases towards the web as it separates from the drum in a plasma-enhanced chemical vapor deposition system reduces the sticking of the web to the drum, and thus prevents power supply dropouts. The gas supplied can form into a plasma that helps dissipate the static charge which builds onto the web as it rolls off of the drum. By reducing the arcing and power supply dropouts, the quality of the deposited layer formed in a deposition zone can be improved.
