摘要:
In order to form a more stable silicon pillar which can be used for the formation of vertical transistors in DRAM cells, a multi-step masking process is used. In a preferred embodiment, an oxide layer and a nitride layer are used as masks to define trenches, pillars, and active areas in a substrate. Preferably, two substrate etch processes use the masks to form three levels of bulk silicon.

Systems, methods, apparatus, and computer program products are provided for monitoring the transfer of cargo, such as a shipping container, to and from a transporter, such as a truck. Identification codes are provided on the cargo and the transporter to aid in the identification of the cargo and the transporter. One or more identification code receiving devices, such as a camera, may be associated with a cargo moving apparatus, such as a crane, and configured to automatically capture the transporter identification code and the cargo identification code as the cargo is being transferred to or from the transporter. The transporter identification code and the cargo identification code can be associated with each other along with other information about the transfer in order to monitor the transfer. In this regard, identification information may be communicated to a shipping terminal's operating system to provide real-time information about one or more transfers occurring within a shipping terminal.

The invention provides a self-closing thermal protection sheath. The sheath is formed as a woven structure. The woven structure includes first strips of a monofilament as the weft filament interwoven with second strips different than said first strips as the warp filaments.

摘要:
A circular saw has one or more louvers in the housing which direct air exiting the housing toward a work piece, together with openings in other components of the saw located between the louvers and the work piece so that sawdust and other debris that is produced during operation of the saw will be blown out of the way and will not interfere with the line of sight of the user.
摘要:
The present invention is a method of forming an optical film including the following steps: providing a first film of a first material, extruding a second material to form a second film in a molten state; maintaining the second film in a molten state; bringing the first film proximate the molten second film; patterning the molten second film to form a plurality of structures, the structures defining a plurality of cavities therebetween; and solidifying the molten second film.
摘要:
Target valuations for company stocks are produced based on the strength and quality of their technology. The valuations are derived from a combination of indicators that measure the quality of companies' patented technology, and their commitment to research and development. Indicators may include citation indicators that measure the impact of companies' patents on later technological developments, the strength of the link between companies' patents and scientific research, the speed at which companies innovate, and the proportion of companies' sales spent on research and development. The technology-based valuation may be used to identify investment opportunities in the stock market.
