摘要:
The present invention relates to an apparatus for collecting soluble component-removed powder that collects soluble component-removed and poorly soluble component-containing powder to recycle by removing the soluble component from the powder through filtering using a vacuum pump after mixing soluble component- and poorly soluble component-containing powder and a solvent dissolving the soluble component, and a method of the same. According to the invention, it can be easily achieved to collect and utilize soluble component-removed powder, after the soluble component is dissolved in a solvent, by vacuum pumping the solvent through a filter and then discharging a solution containing only the soluble component, further effectively prevent overload by removing the soluble component-removed powder stuck on the surface of the filter in the vacuum pumping through backwashing.

The present invention provides a method of surface passivation of colloidal nanocrystalline materials using a ligand exchange process in which quantum nanoparticles of pre-selected size and shape has polymer multidentate ligands bound at the surface of the nanocrystals for stabilizing quantum size-dependent properties of nanocrystals and providing colloidal stability of the nanoparticles in solvents. The method includes preparing a colloidal dispersion of nanoparticles, preparing a suitable polymer multidentate ligand and dissolving said suitable polymer multidentate ligand in a fluid, the polymer multidentate ligand having first portions which can bind to a surface of the nanoparticles and a second portion which does not bind to the surface of the nanoparticles, and mixing the fluid containing the suitable polymer with the colloidal dispersion of nanoparticles under conditions suitable to induce binding of at least some of the first portions of the polymer multidentate ligand onto the surface of the nanoparticles, the suitable polymer multidentate ligand being selected so that the at least some of the first portions which bind to the surface to stabilize quantum size-dependent properties of the nanocrystals, and the second portion which does not bind to the surface provides colloidal stability of the nanoparticles in a desired fluid.

Disclosed is an SD memory card socket for preventing an SD memory card from being accidentally removed from the SD memory card socket. The SD memory card socket includes guide pieces formed on an edge of a connector housing facing a side of the SD memory card so as to form a guide slot therebetween in a longitudinal direction. A slider moves forward and backward in the longitudinal direction along the guide slot when inserting and removing the SD memory card. The slider has a fixing hole formed at a front end and a hidden hole formed at a rear end, the hidden hole being open in a downward direction. A first end of a locking bar is inserted into the fixing hole to allow the locking bar to rotate about the fixing hole, while a second end of the locking bar is inserted into the hidden hole to allow the second end to protrude out of the hidden hole when rotated about the fixing hole. A locking release guide protrusion is formed on an inner face of a guide piece, so as to guide a horizontal part of the locking bar to urge the second end of the locking bar toward insertion into the hidden hole when the slider moves to a home position

摘要:
The present invention is related to a system for optical coherence tomographic imaging of turbid (i.e., scattering) materials utilizing multiple channels of information. The multiple channels of information may be comprised and encompass spatial, angle, spectral and polarization domains. More specifically, the present invention is related to methods and apparatus for utilizing optical sources, systems or receivers capable of providing (source), processing (system) or recording (receiver) a multiplicity of channels of spectral information for optical coherence tomographic imaging of turbid materials. In these methods and apparatus the multiplicity of channels of spectral information that can be provided by the source, processed by the system, or recorded by the receiver are used to convey simultaneously spatial, spectral or polarimetric information relating to the turbid material being imaged tomographically. The multichannel optical coherence tomographic methods can be incorporated into an endoscopic probe for imaging a patient. The endoscope comprises an optical fiber array and can comprise a plurality of optical fibers adapted to be disposed in the patient. The optical fiber array transmits the light from the light source into the patient, and transmits the light reflected by the patient out of the patient. The plurality of optical fibers in the array are in optical communication with the light source. The multichannel optical coherence tomography system comprises a detector for receiving the light from the array and analyzing the light. The methods and apparatus may be applied for imaging a vessel, biliary, GU and/or GI tract of a patient.

摘要:
An extensible, object-oriented framework describes various generic elements of legacy automation systems. That framework is used as a basis for porting one or more of those elements to another (“target”) automation system. Objects in the framework, known as “extensions,” adapt information from the legacy system to a corresponding, generic representation. Compilers express those representations in the target system. The framework thus translates the “old” automation configuration for use in a “new” automation system. The scheme can be extended to accommodate arbitrary control systems (i.e., other manufacturers and product lines), new sub-domains within the automation domain (e.g. operator interfaces, batch control etc.) and new target systems without altering the core framework.
