摘要:
A system and method for movably sealing a vapor deposition source is described. One embodiment includes a system for coating a substrate, the system comprising a deposition chamber; a vapor pocket located within the deposition chamber; and an at least one movable seal, wherein the at least one movable seal is configured to form a first seal with a first portion of a substrate, and wherein the first seal is configured to prevent a vapor from leaking past the first portion of the substrate out of the vapor pocket. In some embodiments, the movable seal may comprise a first flange, wherein the first flange forms a wall of the vapor pocket; and a second flange, wherein the second flange is configured to be movably disposed within a first groove of the source block.

A patient support platform or mobile support cart is provided. The mobile support cart includes a transmission system that allows the patient and/or medical staff member to choose a stop, walk or roll mode. In the stop mode, the castor wheels are prevented from rolling across the floor by a braking mechanism. In the walking mode, the transmission causes a tracking wheel to engage the floor for providing tracked or guided motion to the mobile support cart. In a roll mode, the tracking wheel is raised and is disengaged from the floor, and the castor wheels are free to rotate. The platform is capable of supporting devices that may be attached or associated with a patient throughout their stay at a healthcare facility. The braking mechanism can include a cable and an associated brake arm, with the cable positioned to allow braking without inhibiting the ability of the castor wheel to swivel with respect to a castor mounting plate.

A castor wheel assembly, alone or in combination with a patient support platform or mobile support cart, is provided. The mobile support cart includes a stop mode in which the castor wheels are prevented from rolling across the floor by a braking mechanism. The platform is capable of supporting devices that may be attached or associated with a patient throughout their stay at a healthcare facility. The castor wheel assembly can incorporate a braking mechanism operated by a cable that extends through a mounting plate.

摘要:
A method for making a polycrystalline composition, wherein the method includes the steps of a) preparing a precursor material, b) heating the precursor material to a reaction temperature in the presence of a precursor vapor supplied from a source at a preselected partial pressure, for a sufficient time to initiate an interaction between the precursor material and the precursor vapor to form a heated precursor material, and c) cooling the heated precursor material at a predetermined cooling rate, optionally, in the presence of the precursor vapor supplied at a partial pressure, to yield the polycrystalline composition. A device for implementing the method of the present invention is also provided
