Patent number: 8916213Abstract: A process for the production of animal feed additives from fermentation broth containing L-lysine is disclosed. The process does not require filtering of biomass in order to remove the biomass and produces granulated lysine of controllable lysine content with a high bulk density, low viscosity, and a low hygroscopic property which does not require the addition of an anti-absorptive substance. In this process, a lysine fermentation broth produced after slant culture, flask culture, seed process, and cultivation process is concentrated to a solid content of about 44˜52%. A product with low hygroscopicity, high bulk density, and the intended amount of contents is produced after being mixed with substances for controlling the amount of contents and granulated by coating the surface of the seeds. This process enables a production of animal feed additives having a lysine-HCl content of at least 65%, a water content of at most 3%, and a bulk density of 670±50 kg/m3.Type: GrantFiled: July 31, 2006Date of Patent: December 23, 2014Assignee: CJ CorporationInventors: Youn Jae Lee, Yong Bum Seo, Seung Woo Han, Jae Hun Yu, Soon Won Hong, Gyu Nam Cho, Won Seop Choi

Publication number: 20100225631Abstract: A flat panel display device and a source driver circuit for the flat panel display device are provided for performing multiple driving operations within a unit sourcing period. In the flat panel display device, multiple driving operations are performed within the unit sourcing period, and source voltages are supplied to a selected number of data lines in each driving operation. In this case, one DAC is driven to generate source voltages for a plurality of data lines. In the flat panel display device, the number of the DACs is reduced and the overall layout area is greatly reduced. Also, standby power consumption can be greatly reduced due to the reduced number of amplifiers. Since the source voltages provided by the same amplifier are provided to adjacent data lines, a metal layer can be easily wired in the display panel.Type: ApplicationFiled: February 3, 2010Publication date: September 9, 2010Applicant: TLI INC.Inventor: Soon Won HONG
