摘要:
A can end (2) is described for a metal beverage can, optionally for carbonated drinks, the can end including a cap top (3), arranged in connection to a pull tab (4) configured to remove the cap top along a pre-defined groove (9), to thereby create a drinking or pouring aperture; an elastic resilient element (10) attached to the can end; and a resiliently operated shut-off valve (6) that is part of or is connected to the elastic resilient element (10) and that is configured to seal the drinking or pouring aperture after drinking or pouring; wherein the cap top (3) is configured to remain located, after the removal, on top of the shut-off valve (6). Further, a can including such a can end, and a method for opening and reclosing such a can are described, as well as a method for producing such a can.

摘要:
An apparatus to releasably affix a rotating cylindrical magnetron target to a spindle utilizes a threaded spindle collar engaging threads on the outside surface of the target, with a single water-to-vacuum seal located at the target and spindle interface. The threads may be removable from the target, enabling efficient assembly/disassembly and recycling.
摘要:
Material utilization and process stability for a rotating cylindrical magnetron target used in a sputtering system are improved by incorporation of a second magnet structure or “race track”, allowing the power density on the target surface to be reduced by approximately 50% for any given point where magnetic confinement of the plasma exists. Offsetting one race track relative to the other along the longitudinal axis of the target reduces the power density at each turn-around area (relative to the longitudinal area). Modestly increasing the target material thickness at the ends of the target allows nearly all of the material between the turn-around areas to be sputtered.
