Integrated circuits, the key components in thousands of electronic and computer products, are generally built layer by layer on a silicon substrate. One common layer-formation technique, known as chemical-vapor deposition (CVD), produces uneven layers and covers vertical surfaces poorly. An emergent technique, atomic-layer deposition, overcomes these shortcomings, but has others, such as slow deposition rates and longer than desirable cycle times, particularly as applied to deposition of aluminum oxide. Accordingly, the inventors devised unique atomic-layer deposition systems, methods, and apparatus suitable for aluminum-oxide deposition. One exemplary system includes an outer chamber, a substrate holder, and a gas-distribution fixture that engages or cooperates with the substrate holder to form an inner chamber within the outer chamber. The inner chamber has a smaller volume than the outer chamber, which ultimately requires less time to fill and purge and thus promises to reduce cycle times for deposition of materials, such as aluminum oxide.

A lighting device includes a DC/DC power converter, a controller/processor electrically connected to the DC/DC power converter, a light emitting diode (LED) current control circuit communicably coupled to the controller/processor and electrically connected to the DC/DC power converter, and two or more LEDs comprising at least a first color LED and a second color LED electrically connected to the LED current control circuit. The LED current control circuit provides an on/off signal having a cycle time to each LED in response to one or more control signals received from the controller/processor such that the two or more LEDs produce a blended light having a specified color based on how long each LED is turned ON and/or OFF during the cycle time.

Different periods of an ALD cycle are performed using different purge flows and, in some cases, different pumping capacities, while maintaining the reactor chamber at a nominally constant pressure. The purge flows may, in some cases, utilize different gasses and/or may be provided through different flow paths. These operations provide for ALD cycle time improvements and economical operation with respect to consumables usage. In some embodiments the use of an annular throttle valve provides a means for controlling downstream flow limiting conductances in a gas flow path from the reactor chamber.

A monitor for an electric arc welder as the welder performs a selected arc welding process by creating actual welding parameters, such as arc current and arc voltage, between an advancing welding wire and a workpiece, where the process involves an arc and is defined by a series of rapidly repeating wave shapes constituting a weld cycle with a cycle time, the wave shapes are each segmented into time states having command signals corresponding to the actual parameters and a time duration. The monitor selects a specific wave shape state, reads one of the actual parameters, compares the actual read parameter with a function of the command signal corresponding to the actual parameter, and uses-the comparison to generate a characteristic of the welding process during the selected state.

A portfolio selector technique is described for selecting publicly traded companies to include in a stock market portfolio. The technique is based on a technology score derived from the patent indicators of a set of technology companies with significant patent portfolios. Typical patent indicators may include citation indicators that measure the impact of patented technology on later technology, Technology Cycle Time that measures the speed of innovation of companies, and science linkage that measures leading edge tendencies of companies. Patent indicators measure the effect of quality technology on the company's future performance. The selector technique creates a scoring equation that weights each indicator such that the companies can be scored and ranked based on a combination of patent indicators. The score is then used to select the top ranked companies for inclusion in a stock portfolio. After a fixed period of time, as new patents are issued, the scores are recomputed such that the companies can be re-ranked and the portfolio adjusted to include new companies with higher scores and to eliminate companies in the current portfolio which have dropped in score. A portfolio of the top 10-25 companies using this method and a relatively simple scoring equation has been shown to greatly exceed the S&P 500 and other indexes in price gain over a ten year period.

A collaborative engineering environment (CEE) enables the effective capture, management, communication, and exploitation of all product related information to a project team. The systematic employment of this information offers substantial improvements in productivity, cost savings, cycle time reductions, product integrity, and lifetime supportability of the system. Advanced CEE capabilities exploit and leverage the engineering, architectural and technological expertise of enterprise subject matter experts (domain experts) across multiple complex systems development and integration activities. The CEE provides a tightly coupled process automation using reusable product elements for coupling information with engineering processes and ensuring adherence to repeatable and traceable engineering processes. A product catalog provides a single information management point for intrinsic complex product characteristics and facilitates the propagation of that information to engineering teams incorporating the complex product into their system designs. The intrinsic complex product characteristics are augmented with implementation specific information to fully describe the complex product in the system design.

Two-component systems are described which are suitable for underlining, adhesive bonding of the crimped fold and sealing of auto body sections, particularly for crimped fold sealing of add-on vehicle parts. The two-component systems attain the requisite grip strength for mounting the add-on parts on the body as well as the requisite strength and dimensional stability for the production process up to and with the CIP passage, within the predetermined cycle time, on the basis of cross-linking of the sealant composition twice. In one embodiment, the surface of the two-component system is pre-cross-linked by a UV-induced reaction and by the cross-linking of the two-component system to the extent of portability. In addition, two-component systems are described which cross-link intentionally only partially up to a consistency that permits a rugged course of the process through cleaning baths and which harden completely only by means of a further hardening process, for instance in the CIP forced circulation oven.

The average propylene cycle yield of an oxygenate to propylene (OTP) process using a dual-function oxygenate conversion catalyst is substantially enhanced by the use of a combination of: 1) moving bed reactor technology in the catalytic OTP reaction step in lieu of the fixed bed technology of the prior art; 2) a separate heavy olefin interconversion step using moving bed technology and operating at an inlet temperature at least 15° C. higher than the maximum temperature utilized in the OTP reaction step; 3) C₂ olefin recycle to the OTP reaction step; and 4) a catalyst on-stream cycle time of 700 hours or less. These provisions hold the build-up of coke deposits on the catalyst to a level which does not substantially degrade dual-function catalyst activity, oxygenate conversion and propylene selectivity, thereby enabling maintenance of average propylene cycle yield for each cycle near or at essentially start-of-cycle levels.

The multi-layer film structure having an inner sealing layer which comprises metallocene resin, a core which includes polypropylene copolymer and an outer layer and wherein the multi-layer film structure has a thickness within a range between about 50 and 70 microns (2.0-2.75 mil). By utilizing this thin film with specific properties the sealers may be operated at lower temperatures thereby resulting in an energy saving and they produce seals having improved seal strength of 30% to 50% as compared with known prior mono-layer polyethylene film. The seal initiation temperature is reduced by 10° C. to 15° C. and the film exhibits an improved machine direction tensile strength of 25% to 40% and an improvement of 30% to 50% in puncture resistance as compared with a 76 microns (3 mil) mono-layer polyethylene film. This results in a reduction in the sealing cycle time and an increase in the throughput of the machine. This results in a liquid pouch having a substantial improvement in drop test performance, puncture resistance and seal strength. The machine accomplishes better seals with less energy, requires less downtime for roll changes and maintenance and increase throughput.

A method of sterilizing an article by sequentially exposing the article to hydrogen peroxide and ozone is disclosed. The article is exposed under vacuum first to an evaporated aqueous solution of hydrogen peroxide and subsequently to an ozone containing gas. The exposure is carried out without reducing the water vapor content of the sterilization atmosphere, the water vapor content being derived from the aqueous solvent of the hydrogen peroxide solution and from the decomposition of the hydrogen peroxide into water and oxygen. The complete sterilization process is carried out while the chamber remains sealed and without removal of any component of the sterilization atmosphere. For this purpose, the chamber is initially evacuated to a first vacuum pressure sufficient to cause evaporation of the aqueous hydrogen peroxide at the temperature of the chamber atmosphere. The chamber is then sealed for the remainder of the sterilization process and during all sterilant injection cycles. Keeping the chamber sealed and maintaining the hydrogen peroxide and its decomposition products in the chamber for the subsequent ozone sterilization step results in a synergistic increase in the sterilization efficiency and allows for the use of much lower sterilant amounts and sterilization cycle times than would be expected from using hydrogen peroxide and ozone in combination.
