    摘要: Crystal lattice dislocations in material surrounding trench capacitors and other trench structures are avoided by alteration of stresses such as decreasing compressive stresses and/or development of persistent tensile forces within material deposited in the trench and thus at the material interface formed by the trench. Such alteration of stresses is achieved by volume reduction of a film deposited in the trench. The material is preferably a hydrogenated nitride of silicon, boron or silicon-carbon alloy which may be reduced in volume by partial or substantially complete dehydrogenation during subsequent heat treatment at temperatures where the film will exhibit substantial creep resistance. The amount of volume reduction can be closely controlled by control of concentration of hydrogen or other gas or volatile material in the film. Further fine adjustment of stresses can be achieved in combination with this mechanism by volume reduction of other materials which may be used, in part, to confine the film through other mechanisms such as annealing.

    摘要: A tobacco expansion method is provided whereby cured tobacco is first moistened with a humectant solution, as is conventional in the industry, to increase the resident liquids thereof. Next, the prepared tobacco in shredded form is placed in a sealed chamber and the chamber evacuated to vaporize a portion of the resident liquids. Next, ethyl alcohol vapor is allowed to enter the pressure chamber below 70 mm (Hg) absolute to prevent a water-ethyl alcohol azeotrope from forming. Thereafter, a hydrocarbon vapor, such as n-pentane vapor, is directed into the chamber and the pressure restored to atmospheric. The n-pentane vapor diffuses into the cellular structure of the tobacco with the assistance of the ethyl alcohol, whereafter the tobacco is heated and the n-pentane and ethyl alcohol acts as a propellant to expand the tobacco.

    摘要: A portable vessel includes a hard shell front hull section, a hard shell aft hull section, a flexible water tight material hull section affixed to the front hull section and the aft hull section in a water tight manner, the material section forming the middle portion of the hull of the vessel, and a tension-adjustable frame assembly. Tensioning of the frame assembly during assembly of the vessel causes tensioning of the material hull section from a less than taught state to a taught state about the frame assembly and wherein the disassembled components of the vessel may be configured into a backpack configuration for portage by a user.
