| 20110215227 | Photosensitive Detector with Composite Dielectric Gate MOSFET Structure and Its Signal Readout Method - The present invention relates to a photosensitive detector with a composite dielectric gate MOSFET structure and its signal readout method. The MOSFET structure detector is formed on a p-type semiconductor substrate. N-type semiconductor regions locate on the two sides of the top part of the p-type semiconductor substrate to form a source and a drain. An underlying dielectric layer, a photo-electron storage layer, a top dielectric layer, and a control gate are stacked on the substrate in sequence. The top insulating dielectric layer can prevent the photoelectrons stored in the photo-electron storage layer from leaking into the control gate. The source and the drain are floating when photoelectrons are collected and injected into the photoelectron storing layer to be held therein. There is a transparent or semi-transparent window for detecting incident light forming on the substrate or gate surface. This invented detector has excellent scalability, basic compatibility with the flash memory fabricating technology, low leakage current, higher imaging speed than CCD, non-sensitivity to processing defects, larger dynamic range than other structures and higher accuracy of signal readout. | 09-08-2011 |

| 20110155669 | METHOD FOR TRACE PHOSPHATE REMOVAL FROM WATER USING COMPOSITE RESIN - The invention discloses a novel method for trace phosphate removal from water by using a composite resin. Firstly, adjusting the pH value of the raw water to 5.0˜9.0 and prefiltering the water, then leading the filtrate through an absorption tower packed with the composite resin, the trace phosphate in the water is therefore absorbed onto the composite resin; stopping the absorption run when it reaches the leakage point, using a binary NaOH-NaCl solution as the regenerant of the exhausted sorbent, followed by rinsing the composite resin-filled absorption tower with saturated carbon dioxide solution to regenerate the resin. In this invention, a composite resin with nanosized hydrated ferric oxide (HFO) or hydrous manganese dioxide (HMO) particles loaded on its surface is adopted as the absorbent for enhanced phosphate removal from water. A significant decrease of phosphate content in the effluent from this treatment system is found from 0.05-20 ppm to less than 20 ppb (calculated in P), despite of the coexisting competing anions as sulfate, chloride, and hydrocarbonate at much higher molar concentrations than phosphate. This invention is characteristic of large treatment capacity and efficient regeneration for repeated use of the absorbent. | 06-30-2011 |
