ar 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.

A number of semiconductor devices such as varactor diodes (215, 217, 229, 233) are used for tuning respective capacitors in the capacitive network (201-209). A single voltage source (Vc) is used for tuning each one of the respective varactor diodes for moving the resonant frequency of the filter over a substantially wide frequency range. Full Article
ar Apparatus, system and methods for enabling linearity improvement in voltage controlled variable capacitors By www.freepatentsonline.com Published On :: Tue, 17 Aug 2010 08:00:00 EDT An embodiment of the present invention provides an apparatus, comprising at least one anti-parallel pair VVC network comprised of two parallel VVCs with one biased in the opposite polarity of the other and at least one anti-series VVC network comprised of two VVCs configured in series, one biased in the opposite polarity of the other such that the resulting AC capacitive variations produce a desired capacitance variation.

ar Receiver apparatus and receiver system By www.freepatentsonline.com Published On :: Tue, 26 Apr 2011 08:00:00 EDT A receiver apparatus 3 has a digital circuit portion 13 that converts a compressed digital signal outputted from a digital demodulating portion 12 into digital video and audio signals and a video/audio output circuit 14 that converts the digital video and audio signals outputted from the digital circuit portion 13 into analog video and audio signals. With this configuration, a video/audio processing IC for digital signal processing no longer needs to be mounted on the circuit board of a video display apparatus 4, and thus a receiver system can be realized with a video display apparatus having a simple configuration.

ar Apparatus for airfield management By www.freepatentsonline.com Published On :: Tue, 02 Aug 2011 08:00:00 EDT A system for supervising the landing of an aircraft by a supervisor in a control station, each of the aircraft being incapable of being controlled by any personnel onboard, the system comprises a control station and onboard aircraft control apparatus. The station includes an input device, responsive to the supervisor, for producing a control signal for controlling the landing of the aircraft; and a transmitting device, coupled to the input device, for communication with the aircraft. The aircraft apparatus includes a receiving device for communication with the station; a logic device, coupled to the receiving device, for controlling the aircraft which is programmed to pilot the aircraft to the vicinity of the airfield. The control signal is selected by the supervisor, based on the supervisor's observations of the aircraft and is transmitted to the logic device; in response thereto, the logic device controls the aircraft.
