| 20110290891 | RFID TAG HAVING CAPACITIVE LOAD - The present invention relates to an RFID tag having capacitive load, including: an antenna unit, a capacitive load and an RFID device. The antenna unit includes two metal sheets and a conductive substrate, and the metal sheets are disposed at a corresponding position above the conductive substrate and electrically connected to the conductive substrate. The capacitive load is electrically connected to the metal sheets. The RFID device feeds the antenna unit by electrically connecting to the metal sheets or coupling. This dramatically decreases the operating frequency, so the imaginary part of impedance is higher with the same size of the antenna unit, thereby reducing the size of the RFID tag. As a result, the weight is reduced, the manufacture process is simplified and the subsequent structure can be easily adjusted. | 12-01-2011 |
| 20110241253 | METHOD FOR MANUFACTURING COBALT ALLOY-BASED CERAMIC COMPOSITE SPUTTERING TARGET - A method for manufacturing a cobalt (Co) alloy-based ceramic composite sputtering target is provided. A cobalt ingot and a chromium (Cr) ingot are melted in vacuum and then nebulized to form a cobalt-chromium (CoCr) alloy powder. Additionally, a ceramic powder and a platinum powder are wetly mixed to form a platinum-ceramic (Pt-ceramic) slurry, in which the ceramic powder is applied onto the platinum powder's surface uniformly. Next, the CoCr alloy powder and the Pt-ceramic slurry are wetly mixed to form a CoCrPt-ceramic slurry. Thereafter, the CoCrPt-ceramic slurry is dried, molded and compressed to form the cobalt alloy-based ceramic composite sputtering target. The resulted cobalt alloy-based ceramic composite sputtering target, which has a fine and dense structure, uniform composition and lower magnetic permeability, is beneficial to a magnetron sputter deposition process, as well as a film sputtering process used in the magnetic recording industry. | 10-06-2011 |
| 20110193274 | RESIDENT MEASUREMENT SYSTEM FOR CHARGE LEVEL OF BLAST FURNACE - A resident measurement system for a charge level of a blast furnace includes a chamber, a servo system, a distance measurement unit, and a cooling-cleaning unit. The chamber is combined with a lateral furnace wall of the blast-furnace, covers an opening of the furnace wall, and has a pivoting hole. A pivot of the distance measurement unit is pivotally disposed at the pivoting hole, and the distance measurement unit is driven by the servo system to perform a motion with the pivot as a movement center, so as to measure the charge level. The cooling-cleaning unit is used to supply a high-pressure gas, which flows through the distance measurement unit to perform cooling and cleansing operations. The measurement system is small in dimension, and capable of scanning the charge level in an environment with high temperature, high concentration of dust, and high corrosion in the blast furnace furnace, establishing charge level information into a two-dimensional charge level mode, and obtaining a charge level profile distribution situation in real time, thereby promptly modifying a burden distribution mode. | 08-11-2011 |
