Publication number: 20180186687Abstract: A sintered machinable glass-ceramic is provided. The machinable glass-ceramic is formed by mixing phyllosilicate material having a sheet structure, with a glass fit and firing the mixture at relatively low temperatures to sinter the phyllosilicate, while maintaining the sheet-like morphology of the phyllosilicate and its associated cleaving properties. The sintered machinable glass-ceramic can be machined with conventional metal working tools and includes the electrical properties of the phyllosilicate. Producing the sintered machinable glass-ceramic does not require the relatively high-temperature bulk nucleation and crystallization needed to form sheet phyllosilicate phases in situ.Type: ApplicationFiled: December 2, 2016Publication date: July 5, 2018Inventors: Srinivasan Sridharan, George E. Sakoske, John J. Maloney, Cody Gleason, Gregory R. Prinzbach, Bradford Smith, Chih Cheng Wang

Patent number: 7972513Abstract: A process for treating nitrogenous wastewater contains an autotrophic denitrification reaction, a heterotrophic denitrification reaction and a COD removal reaction simultaneously and mixedly taking place in a single reactor. The nitrification reaction is caused by nitrifying bacteria, in which ammonium is oxidized into nitrite. The autotrophic denitrification reaction is caused by autotrophic denitrifying bacteria, in which ammonium used as electron donor and nitrite used as electron acceptor are converted into nitrogen gas and nitrate. The heterotrophic denitrification reaction is caused by heterotrophic denitrifying bacteria, in which nitrate and COD are consumed. It is not necessary to build two separate reactors for aerobic nitrification and anaerobic denitrification, thereby effectively reducing the fabrication and operation cost.Type: GrantFiled: October 9, 2009Date of Patent: July 5, 2011Assignees: Leaderman & Associates Co., Ltd., National Chiao Tung UniversityInventors: Der-Ming Lee, Ming-Kuei Chiang, Chin-Te Chen, Keng-Chuan Sung, Jih-Gaw Lin, Chih-Cheng Wang

Publication number: 20110090106Abstract: A 12-bit DAC includes a resistor string, three 16-to-1 selectors and an adder. The 12-bit DAC receives a 12-bit digital input data and provides a corresponding analog output voltage with 3-segmented conversion. The resistor string includes a plurality of voltage-dividing units for providing a plurality of reference voltages corresponding to each segment of conversion. After receiving the plurality of reference voltages generated by the resistor string, the three 16-to-1 selectors output 3 reference voltages corresponding to the three segments of conversion according to the 4 most significant bits, 4 least significant bits and the other 4 bits in the 12-bit digital input data, respectively. The adder can then generate the corresponding output analog voltage by summing the 3 reference voltages.Type: ApplicationFiled: November 26, 2009Publication date: April 21, 2011Inventors: Shu-Chuan Huang, Chun-Hsien Chou, Chih-Cheng Wang, Shih-Meng Chang, Chi-Neng Mo
