ac 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.

Circuitry is formed upon a substrate such that an inductor and non-volatile memory capacitor are formed. Additional circuitry can be optionally formed on the substrate as well. The capacitive value of the memcapacitor is adjustable within a range by way of an applied programming voltage. The capacitive value of the memcapacitor is maintained until reprogrammed at some later time. Oscillators, phase-locked loops and other circuits can be configured using embodiments of the present teachings. Full Article
ac IC package with embedded transformer By www.freepatentsonline.com Published On :: Tue, 16 Dec 2014 08:00:00 EST Aspects of a method and system for configuring a transformer embedded in a multi-layer integrated circuit package are provided. In this regard, a windings ratio of a transformer embedded in a multi-layer IC package bonded to an IC may be configured, via logic, circuitry, and/or code in the IC, based on signal levels at one or more terminals of the transformer. The transformer may comprise a plurality of inductive loops fabricated in transmission line media. The integrated circuit may be flip-chip bonded to the multi-layer package. The IC may comprise a signal strength indicator enabled to measure signal levels input to or output by the transformer. The windings ratio may be configured via one or more switches in the IC and/or in the multi-layer package. The IC and/or the multi-layer package may comprise ferromagnetic material which may improve magnetic coupling of the transformer. Full Article
ac Mechanically controlled variable capacitors for impedance tuners By www.freepatentsonline.com Published On :: Tue, 16 Dec 2014 08:00:00 EST An improved grounding technique for mechanically adjustable rotary capacitors uses a directly grounded bronze sliding contact to effectively and continuously ground the rotating comb-like blades of the capacitor. RF measurements of the continuity and repeatability of the capacitance settings prove the suitability of the modified capacitors for using in pre-calibrated multi-capacitor MHz range impedance tuners.

ac Method and apparatus for use in digitally tuning a capacitor in an integrated circuit device By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT A method and apparatus for use in a digitally tuning a capacitor in an integrated circuit device is described. A Digitally Tuned Capacitor DTC is described which facilitates digitally controlling capacitance applied between a first and second terminal. In some embodiments, the first terminal comprises an RF+ terminal and the second terminal comprises an RF− terminal. In accordance with some embodiments, the DTCs comprise a plurality of sub-circuits ordered in significance from least significant bit (LSB) to most significant bit (MSB) sub-circuits, wherein the plurality of significant bit sub-circuits are coupled together in parallel, and wherein each sub-circuit has a first node coupled to the first RF terminal, and a second node coupled to the second RF terminal. The DTCs further include an input means for receiving a digital control word, wherein the digital control word comprises bits that are similarly ordered in significance from an LSB to an MSB.
