| 20120070915 | METHOD FOR COPPER HILLOCK REDUCTION - A method of forming interconnects in integrated circuits includes providing a semiconductor substrate and forming a copper interconnect structure that is formed overlying a barrier layer within a thickness of an interlayer dielectric layer. The copper interconnect structure has a first stress characteristic. The method further loads the semiconductor substrate including the copper interconnect structure into a deposition chamber that contains an inert environment. The semiconductor substrate including the copper interconnect structure is annealed in the inert environment for a period of time to cause the copper interconnect structure to have a second stress characteristic. The semiconductor substrate is maintained in the deposition chamber while an etch stop layer is deposited thereon. The method further deposits an inner-metal dielectric layer overlying the etch stop layer, wherein the annealing reduces copper hillock defects resulting from at least the first stress characteristic. | 03-22-2012 |

| 20100168842 | CORONARY STENT WITH ASYMMETRIC DRUG RELEASING CONTROLLED COATING - A coronary stent is provided with asymmetric drug releasing controlled coating used in interventional therapy of coronary disease, containing a bare stent and a coating consisting of drug and carrier, the coating is coated onto the outer wall surface of the bare stent, and is multi-layered. The drug concentration in the coating increases in sequence from the outer layer to the inner layer. The drugs used in different layers of the coating may be identical or different, and particularly may be one or more selected from taxol, rapamycin, heparin, docetaxel and a combination thereof. The carrier may be a random (lactide-glycolide) copolymer having a molecular weight of 50,000-200,000. The drug-coated stent of the present invention employs highly effective drugs, enabling a thinnest coating and reducing the vascular irritation. The drug release is regulated by altering the coating manner so as to satisfy the clinical requirement for controlled drug release. The employed asymmetric coating promotes regenerative repairing of vascular endothelium. The present invention is a drug-coated coronary stent with reasonable design, with the coating capable of effectively preventing vascular restenosis and reducing occurrence of late thrombosis. | 07-01-2010 |

| 20080267628 | Passive Optical Network System Based on a Wavelength Protection and Protecting Backup Method Thereof - The present invention discloses a passive optical network system based on wavelength protection and the protection backup method thereof. It comprises an optical line terminal (OLT) with two interface circuits, two trunk lines, an optical splitter network, multiple branch lines and optical network units (ONU), each of which is with two interface circuits. The two interface circuits of the OLT transmit downlink optical signals with different wavelengths, while the two interface circuits of the ONU transmit uplink optical signals with different wavelengths. Each trunk line is set with a wavelength division multiplexing (WDM) device and it can only pass the uplink and downlink signals of the connected interface circuits. Each branch line includes a branch optical fiber and a WDM device that is used to transmit two downlink signals to the corresponding interface circuits respectively and meanwhile transmit uplink signals from the two interface circuits as well, so as to form two active/backup bidirectional optical paths between the corresponding interface circuits of the OLT and the ONU. The cost of setting up the system in the present invention is low, but the system can provide hot backup protection for the trunk optical fiber and the OLT. | 10-30-2008 |

| 20080289339 | METHOD AND APPARATUS FOR CONTROLLING THE COMBUSTION IN A GAS TURBINE - A method and apparatus are described for controlling the combustion in a gas turbine. The method includes measuring, by means of one or two calorimeters, the temperature, calorific value and relative density of a gaseous fuel in order to determine the Wobbe index, comparing the Wobbe index value measured with a predefined Wobbe index value for the gaseous fuel and regulating the temperature of the gaseous fuel by means of at least one heat exchanger in order to reach the predefined Wobbe index value. The method may also include using a second gaseous fuel, having a different Wobbe index from the gaseous fuel, or a fuel obtained by mixing the gaseous fuel and the second gaseous fuel, according to arbitrary proportions and variable with time. | 11-27-2008 |
| 20120063883 | METHODS AND DEVICES FOR LOW SPEED LOW TORQUE TESTING OF A ROTOR IN A TURBOMACHINERY - Methods and devices for performing a low torque low speed test to determine whether a rotor of a turbomachinery is free to rotate are provided. A method includes automatically applying a torque to the rotor, the torque gradually increasing up to a predetermined torque value. The method further includes monitoring the speed of the rotor while the torque is gradually increased. The method also includes outputting an indication that the rotor is free to rotate after the speed of the rotor becomes positive, or outputting an indication that the rotor is locked when the speed of the rotor remains zero and the applied torque has reached the predetermined torque value. | 03-15-2012 |
