ng Method for producing sialic-acid-containing sugar chain By www.freepatentsonline.com Published On :: Tue, 28 Jun 2016 08:00:00 EDT [Problem to be Solved] The importance of sugar chains having α2,3- or α2,6-linked sialic acid at their non-reducing ends is known. Industrial production has been demanded for these sugar chain compounds. Particularly, the production of glycoprotein drugs or the like inevitably requires producing in quantity sugar chains having homogeneous structures by controlling the linking pattern (α2,6-linkage or α2,3-linkage) of sialic acid. Particularly, a triantennary or tetraantennary N-type complex sugar chain having sialic acid at each of all non-reducing ends is generally considered difficult to chemically synthesize. There has been no report disclosing that such a sugar chain was chemically synthesized. Furthermore, these sugar chains are also difficult to efficiently prepare enzymatically.[Solution]The present inventors have newly found the activity of sialyltransferase of degrading sialic acid on a reaction product in the presence of CMP and also found that formed CMP can be degraded enzymatically to thereby efficiently produce a sialic acid-containing sugar chain. The present inventors have further found that even a tetraantennary N-type sugar chain having four α2,6-linked sialic acid molecules, which has previously been difficult to synthesize, can be prepared at high yields by one-pot synthesis comprising the elongation reaction of a biantennary sugar chain used as a starting material without performing purification after each enzymatic reaction.

ng Memory cell based array of tuning circuit By www.freepatentsonline.com Published On :: Tue, 26 Jun 2012 08:00:00 EDT A method applied in a tuning circuit comprising a plurality of turning cells is disclosed. the method comprises: laying out a array of tuning cells in a matrix configuration, the matrix comprising a first dimension and a second dimension; assigning a first index associated with the first dimension and a second index associated with the second dimension to each tuning cell; controlling each tuning cell using a word line and a bit line; and summing up outputs from all tuning cells to form a combined output. The tuning cell provides a first circuit value or a second circuit value according to the logical value of the bit line, and the difference between the first circuit value and the second circuit value is determined such that a turning resolution of the tuning circuit is determined.

ng Oscillating apparatus, receiving apparatus, and oscillation control method By www.freepatentsonline.com Published On :: Tue, 09 Jul 2013 08:00:00 EDT In an oscillating apparatus, a detection unit detects a frequency offset between an input signal and a reference signal. A code generation unit specifies a relationship among a code having a predetermined number of bits, the frequency offset, and a voltage to be applied to a voltage-controlled oscillator by a DAC, in accordance with a frequency offset detection state of the detection unit. The code generation unit also generates a frequency offset correction code having a predetermined number of bits in accordance with the specified relationship. The DAC applies the voltage to the voltage-controlled oscillator, in accordance with the relationship described above and the code generated by the code generation unit. The voltage controlled oscillator outputs an oscillator signal having an oscillation frequency corresponding to the voltage applied by the DAC. Full Article

ng Self-calibrating RFID transponder By www.freepatentsonline.com Published On :: Tue, 03 Dec 2013 08:00:00 EST A RFID transponder includes a resonant circuit for providing a clock signal at a predetermined clock frequency, a self-calibration stage for calibrating the resonant circuit's current clock frequency towards the predetermined clock frequency. The self-calibration stage is adapted to compare a first clock frequency of the resonant circuit determined during an interrogation period, during which the resonant circuit is excited by an external RF signal, with a second clock frequency determined during a frequency maintenance period, during which the resonant circuit is excited internally through an oscillation maintenance circuit of the RFID transponder and to calibrate the resonant circuit towards the predetermined clock frequency based on the comparison result.
