A method for forming a mask assembly for use in lithography, typically electron-beam lithography, first forms in a substrate one half of a plurality of opening therethrough and then fills the openings with a removable fill material. Thereafter are formed the other half of the openings which are then filled with the removable fill material. After all the openings have been formed and filled, a support membrane is formed over the substrate and covers the filled windows. A mask layer is then formed over the membrane and patterned. The fill is then removed from all of the windows.

The invention pertains to a process for preparing guaifenesin tannate. The process involves the steps of mixing guaifenesin with tannic acid in the presence of water, continuing to mix the reaction mixture for about 5 minutes to about 4 hours and thereafter removing at least about 80 wt.% of the water by freeze-drying the reaction mixture.
摘要:
A chemiluminescent composition comprising an oxalate component comprising polystyrene or homopoly-.alpha.-methylstyrene containing an oxalate ester; an activator component comprising a solution of a peroxide compound and a catalyst in a first solvent; and a fluorescer contained in the oxalate component, activator component, or in both the oxalate component and the activator component. The first solvent is preferably a propylene glycol dialkyl ether. The chemiluminescent composition, when activated, permits light to be produced of controllable duration.

An aqueous-based self-illuminating bubble-forming composition is provided. The composition comprises an oxalate component comprising an oxalate ester and a solvent; an activator component comprising a peroxide, a catalyst, and water; a surfactant; and a fluorescer in admixture with an aqueous bubble-forming solution. One or more of the same or different surfactants may be present in the activator component; the oxalate component; the activator component and the oxalate component; the aqueous bubble-forming solution; the activator component and the aqueous bubble-forming solution; the oxalate component and the aqueous bubble-forming solution; or in the oxalate component, the activator component and the aqueous bubble-forming solution.

Embodiments, relating to the field of virtual keyboard technologies, of the present invention provide a method for acquiring a virtual keyboard key. The method includes: receiving layout of a universal virtual keyboard and a mapping relationship between terminals and universal virtual keyboard key value mapping tables from a server; acquiring a corresponding universal virtual keyboard key value mapping table according to the identifier of the terminal and the mapping relationship between terminals and universal virtual keyboard key value mapping tables; and acquiring a universal virtual keyboard according to the layout of the universal virtual keyboard and the universal virtual keyboard key value mapping table of the terminal. According to the embodiments of the present invention, a universal virtual keyboard key value mapping table of a terminal is acquired according to the identifier of the terminal and a mapping relationship between terminals and universal virtual keyboard key value mapping tables, and a universal virtual keyboard is acquired according to layout of the universal virtual keyboard and the universal virtual keyboard key value mapping table of the terminal. In this way, virtual keyboards of different terminals have uniform user interface display, thereby reducing operation costs of users to adapt different virtual keyboards due to use of different terminals, and improving user experience.
摘要:
An interactive input system comprises a display surface and processing structure communicating with the display surface. The processing structure presents on the display surface at least one graphic object, the graphic object having properties and a respective solution state comprising a value of at least one property. The processing structure in response to gesture input manipulates the value of the at least one property, and provides an indication as to whether the graphic object is in its solution state in response to the application of a predetermined amount of pressure against the display surface in association with the graphic object. A method and computer readable medium are also provided.
