  • Publication number: 20050271567
    Abstract: The present invention discloses a system for flue gas treatment, wherein the provided system comprises a quench module, a first control module, a filter collecting module, a wet scribing module and a regeneration module. In this system, parts of the particles contained in flue gas are removed in the quench module and the wet scribing module by a first scrubbing solution, and then in wet scribing module a second scrubbing liquid containing particles is formed. Next, the second scrubbing solution is treated in the regeneration module to form a third scrubbing solution, wherein the third scrubbing solution is then fed back to the quench module and/or the wet scrubbing module to substitute the first scrubbing solution for repeating what originally performed via the first scrubbing solution. Furthermore, this invention discloses a method for flue gas treatment.

  • Publication number: 20050147741
    Abstract: A method for fabricating an array pH sensor and a readout circuit device of such array pH sensor are implemented by utilizing an extended ion sensitive field effect transistor to construct the array pH sensor and related readout circuit. The structure of the array sensor having this extended ion sensitive field effect transistor comprises a tin dioxide/metal/silicon dioxide multi-layer structure sensor and a tin dioxide/indium tin oxide/glass multi-layer structure sensor and has excellent properties. Furthermore, the readout circuit and the sensor utilize two signal generators for controlling and reading signals. In particular, the sensor can be effective for increasing the accuracy of measurement and reducing the interference of noise.

  • Publication number: 20050147736
    Abstract: A process for fabricating a whole solid-state pH sensing device by using the polypyrrole as the contrast pH detector and a whole solid-state pH sensing device fabricated by the process are disclosed, wherein said device is a differential pair framework potential electrochemical sensing device fabricated by using a non-insulating solid-state inorganic ion-sensing membrane and a polypyrrole sensing membrane. The largest difference between the device of the present invention and the conventional potentiometric type pH sensor is that the sensor of the invention is a solid-state planar sensor. The differential pair framework uses tin dioxide as the ion-sensing membrane and the reference electrode, and uses a polypyrrole sensor as the differential sensor, wherein the sensitivity of tin dioxide is good and has a value up to 57 mV/pH, and the sensitivity of polypyrrole is about 27 mV/pH.

  • Patent number: 6906524
    Abstract: An ion sening circuit comprises a bridge sensing circuit and a differential amplifying circuit. The bridge sensing circuit detects the ion concentration of the solution in the operation mode of constant voltage and constant current. The differential amplifying circuit compares the output of the bridge sensing circuit and a floating reference voltage, thereby the delivered voltage to the bridge sensing circuit, such that the opeation mode of constant voltage and constant current is formed accordingly. The main features of the disclosed circuit are that it grounds the reference electrode and floats the source terminal. The drawbacks of not being manufactured with intergrated circuits by CMOS technology and low benefits when applied to sensor arrays are avoided by the disclosed circuit.

  • Patent number: 6897081
    Abstract: A method for fabricating a monolithic chip including multi-sensors that can detect pH, temperature, photo-intensity simultaneously and a readout circuit. As such, as well as the multi-sensors, the readout circuit also has a reduced chip area at low cost since selection switches are used to sequentially read pH, temperature and photo-intensity detecting values, wherein the readout action is completed within a clock cycle. The entire structure is fabricated with standard 0.5 ?m CMOS IC, Double Poly Double Metal (DPDM), n-well technology and allows the integration of the on-chip signal conditioning circuitry. The chip fabricated by the method can not only sense the Ph, temperature, photo values but also apply the extended gate field effect transistor (EGFET) on the temperature and light compensation to produce realistic pH values.
