Patent JP-2003530857-A (JP)
IPC: C12R1/01
Filed: 2001-04-17
Abstract: The present invention relates to hybrid glycosylated products, and in particular, to natural products such as polyketides and glycopeptides, and to processes for their preparation. The invention is particularly concerned with recombinant cells in which a cloned microbial glycosyltransferase can be conveniently screened for its ability to generate specific glycosylated derivatives when supplied with polyketide, peptide, or polyketide-peptides as substrates. The invention demonstrates that cloned glycosyltransferases when rapidly screened for their ability to attach a range of activated sugars to a range of exogenously supplied or endogenously generated aglycone templates, show a surprising flexibility towards both aglycone and sugar substrates, and that this process allows the production of glycosylated polyketides in good yield. This overcomes the problem not only of supplying novel sugar attachments to individual polyketides, including polyketides altered by genetic engineering, but also of increasing the diversity of polyketide libraries by combinatorial attachment of sugars.

When the shock damper vibrates in cooperation with the structure 15, the weights 12 and 13 move in the pipe bodies 2 and 3 and strike the shock absorbing materials 8 and 9 to absorb vibration energy of the structure 15. By adjusting curvatures of the pipe bodies 2 and 3, cycles of the weights 12 and 13 can be keep constant regardless of the vibration amplitude of the structure 15. Moving routes of the weights 12 and 13 are limited within the pipe bodies 2 and 3, and moving ranges of the weights 12 and 13 are limited by the end plates 6 and 7.  <P>COPYRIGHT: (C)2003,JPO

Title: Conductive paste and method of manufacturing ceramic circuit board
Inventor: NAKAZAWA HIDEJI
IPC: H05K3/46

Abstract: PROBLEM TO BE SOLVED: To provide a conductive paste for forming a circuit pattern, free from clogging in a screen, fine, thick and almost preventive of bleeding, using a screen printing method for conveniently forming the circuit pattern, and a method of manufacturing a ceramic circuit board. SOLUTION: The conductive paste comprises a conductive metal powder, an organic binder, an organic solvent, a thixotropic agent for increasing the ratio of paste viscosity during high shearing stress to that during low shearing stress, and a surface active agent. The thixotropic agent is of at least one type selected from fatty amide wax, fine powder silica and organic bentonite, and the content of the thixotropic agent is 0.5-2 pts.mass in terms of that of the 100 pts.mass conductive metal powder.
