摘要:
A method of forming a body-tie. The method includes forming the body-tie during an STI scheme of an SOI process. During the STI scheme, a first trench is formed. The first trench stops before a buried oxide layer of the SOI substrate. The first trench may determine a height of body tie that is shared between at least two FETs. A second trench may also be formed within the first trench. The second trench stops in the SOI substrate. The second trench defines the location and shape of a body-tie. Once the location and shape of the body-tie are defined, an oxide is deposited above the body-tie. The deposited oxide prevents certain implants from entering the body tie. By preventing these implants, a source and a drain implant may be self-aligned to the source and drain areas without requiring the use of the photoresist mask to shield the body tie regions from the source and drain implant.

The invention relates to a device, in particular for the treatment of low-viscosity polymer melts, containing a vessel (1) with a stirrer element, the stirrer element (6) essentially comprising a support structure which passes through the vessel and on which surface formers (8) are arranged. According to the invention, the support structure is designed as a cage-like rod frame (7).This results in the following advantages:1. Owing to the now possible continuous wetting or wiping of the surfaces, encrustations and inhomogeneities are avoided.2. Due to enhanced cascading with weir plates, the residence time spectrum can be controlled, which likewise improves the product quality.3. The flexing of the stirrer element is reduced.

Most electric light sources flicker, that is, the intensity of the light that is produced varies substantially in a periodically repeating pattern. In sensitive individuals, light flicker can cause headaches and other undesirable symptoms. This invention comprises a light sensor that measures light intensity, signal processing that identifies the flicker component of the light, and electrically controlled lenses of glasses (spectacles) that rapidly darken or become more transparent so as to cancel most of the flicker. This reduces the flicker seen by the wearer of the glasses, reducing discomfort.

Most electric light sources flicker, that is, the intensity of the light that is produced varies substantially in a periodically repeating pattern. In sensitive individuals, light flicker can cause headaches and other undesirable symptoms. However, humans cannot directly perceive that common light sources are flickering. This invention comprises a light sensor that measures light intensity, a means of signal processing that identifies and isolates the flicker component of the light, and an audio amplifier that amplifies the flicker component so that it can be converted to sound by a speaker or headphones. This makes it easy for ordinary people to identify and characterize flickering sources of light because they can directly perceive the flicker as sound.

The invention provides a biocidal composition for controlling the growth of microorganisms in swimming pools and other aqueous systems. The composition includes: an antimicrobial substance for controlling microbial growth; an ionene polymer; and a synergist. The antimicrobial substance may be selected from the group consisting of: quaternary ammonium compounds such as cetylpyridinium chloride and benzalkonium chloride; isothiazolinone-derived compounds such as methylisothiazolinone; methylene bisthiocyanate; dibromonitrilopropionamide; and 2-bromo-2-nitropropane-1, 3-diol. The ionene polymer is preferably:poly[oxyethylene(dimethyliminio)-ethylene(dimethyliminio)-ethylene)dichloride]. The synergist may be selected from the group consisting of triethanolamine, diethanolamine, ethanolamine, ethanol, and triethylamine. Preferably the synergist is triethanolamine.

The present invention relates to a process for producing PET based on titanium catalyst having acceptable properties for resin used in the production of bottles for beverages. More particularly the invention relates to a process in which the incoming pre-polymer temperature is higher than the final outlet temperature in the final melt phase polycondensation reactor.

A process is disclosed for the preparation of a polyester polymer or polyester copolymer under superatmospheric pressure conditions in a pipe or tubular reaction under turbannular flow conditions. Reaction material having a glycol equivalents to carboxylic acid equivalents mole ratio of from 1.0:1 to 1.2:1, together with a superatmospheric dense gaseous medium are fed co-currently to the reactor. Dicarboxylic acid and/or diol raw materials may be injected into any of the reaction zones in the process during operation to achieve the overall desired mole ratio balance. The process operates at temperatures of from about 220.degree. C. to about 320.degree. C., with turbannular flow achieved before the polymer product and gas exit the reactor process. The pressure in the reaction zones can be in the range from 15 psia to 2500 psia. A polymer product having a DP of a greater than 40, more preferably at least about 70, is achieved by the transfer of water from the reacting material polymer melt to the gaseous medium in the reactor.

Systems and methods for transforming applications to provide uniform mechanisms for commenting on application objects, and mechanisms for collecting and processing feedback are described herein. An aspect provides for analyzing application code for at least one user action event handler associated with at least one object; and for modifying each at least one user action event handler located within the application code to contain at least one action configured to handle feedback for the associated at least one object; wherein invoking the at least one user action event handler triggers the at least one action configured to handle feedback. Other embodiments and aspects are also described herein.
摘要:
In a method of fabricating a giant magnetoresistive (GMR) device a plurality of magnetoresistive device layers is deposited on a first silicon nitride layer formed on a silicon oxide layer. An etch stop is formed on the magnetoresistive device layers, and a second layer of silicon nitride is formed on the etch stop. The magnetoresistive device layers are patterned to define a plurality of magnetic bits having sidewalls. The second silicon nitride layer is patterned to define electrical contact portions on the etch stop in each magnetic bit. The sidewalls of the magnetic bits are covered with a photoresist layer. A reactive ion etch (RIE) process is used to etch into the first silicon nitride and silicon oxide layers to expose electrical contacts. The photoresist layer and silicon nitride layers protect the magnetoresistive layers from exposure to oxygen during the etching into the silicon oxide layer.

The present invention is a process for recycling colored polyester. More specifically, colored polyester for recycling is depolymerized by the addition of glycol to form the monomer BHET. The BHET is contacted with activated carbon to remove some colorant. The remaining colorant is extracted with water, alcohol, or glycol to produce white, purified BHET. The white, purified BHET is separated from the extraction solvent (water, alcohol, or glycol) by filtering, decanting, or centrifuging, for example. The purified BHET monomer can be polymerized to polyethylene terephthalate meeting food contact specifications, using known polymerization processes.
