Filed: 2002-12-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a shaft seal equipment which can supply lubricating oil to an upper sliding surface more effectively even when the amount of the lubricating oil becomes smaller than the predetermined amount.  <P>SOLUTION: There is provided a driving shaft 20 vertically extending through an oil room housing 19 in which the lubricating oil 23 is stored. In the oil room housing 19 of a submerged pump, the seal between the driving shaft 20 and the oil room housing 19 is realized by a mechanical seal 24. The oil room housing 19 includes therein an oil revolution prevention plate 28 which prevents revolution of the lubricating oil 23 caused by rotation of the driving shaft 20. The oil revolution prevention plate 28 extends toward the mechanical seal 24 from the inner peripheral portion of the oil room housing 19. The oil revolution prevention plate 28 is arranged at one position in the circumferential direction within the oil room housing 19. The oil revolution prevention plate 28 is formed in the arcuate shape so that the revolving flow of the lubricating oil 23 may be guided toward the mechanical seal 24 by the oil revolution prevention plate 28.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Patent JP-2004513653-A (JP)
IPC: C07K19/00
Filed: 2001-11-20
Abstract: Membrane proteins are difficult to express in recombinant form, purify, and characterize, at least in part due to their hydrophobic or partially hydrophobic properties. Membrane scaffold proteins (MSP) assemble with target membrane or other hydrophobic or partially hydrophobic proteins or membrane fragments to form soluble nanoscale particles which preserve their native structure and function; they are improved over liposomes and detergent micelles. In the presence of phospholipid, MSPs form nanoscopic phospholipid bilayer disks, with the MSP stabilizing the particle at the perimeter of the bilayer domain. The particle bilayer structure allows manipulation of incorporated proteins in solution or on solid supports, including for use with such surface-sensitive techniques as scanning probe microscopy or surface plasmon resonance. The nanoscale particles facilitate pharmaceutical and biological research, structure/function correlation, structure determination, bioseparation, and drug discovery.
