摘要:
Disclosed are an apparatus and method for separation analysis of mannose-6-phosphate (M6P) by post-column fluorescence detection method. The apparatus is based on chromatography, and includes a column with a solid phase having affinity for phosphate, a flow path for the eluate, a heater installed on the flow path for M6P and a basic amino acid to react by heating the eluate in the flow path, and a fluorescence detector installed downstream of the heater for continuously irradiating the eluate with excitation light and measuring the intensity of the emission, and may include in the flow path a supply channel for addition of a basic amino acid between the column and the heater. The method is characterized in that it uses the apparatus and a second mobile phase consisting of a second buffer containing phosphate of predetermined concentration and adjusted to a predetermined pH.
摘要:
After an inner wall tube, made of steel or alloy containing not less than 2% of Cr, whose outer surface thereof is machined and/or ground to a thickness of 0.1 mm or more including the scale layer, is inserted into an outer wall tube, made of ferritic steel containing not less than 2% of Cr, in which an oxide scale layer containing Cr and having a thickness of 10 to 30 μm is formed in the inner surface thereof , cold working at an outside diameter reduction rate of 5 to 30% is performed. Similarly cold worked after an inner wall tube having an oxide scale layer on the outer surface thereof, is inserted into an outer wall tube whose inner surface is machined and ground. A double-walled tube made has a uniform gap and an excellent thermal conductivity, and is suitable as materials for SG tubes of future FBR.

摘要:
An instrument panel is formed symmertrically with respect to a center of the panel. The instrument panel comprises a pair of recesses defined by left and right reinforcing/partition walls, and a pair of lower openings located under the recesses. A meter unit is mounted in the recess to oppose the driver seat. An under cover is mounted in the lower opening which is to oppose the driver seat. The under cover is formed with a hole through which a steering shaft is adapted to be passed. A tray is mounted in the recess which is to oppose the front passenger seat. A glove box is mounted in the lower opening which is to oppose the front passenger seat. The walls for defining the recesses of the instrument panel have a common fixing section usable for mounting any of the meter unit and the tray.
摘要:
A material composition comprising (a) a poly-functional isocyanate, (b) a compound having MW of 600-3,500 and two functional groups polymerizable with an isocyanate group, (c) a compound having MW below 500 and two functional groups polymerizable with an isocyanate group, and (d) a compound having MW below 700 and at least three functional groups polymerizable with an isocyanate group. A shaped polymeric material is made by mixing and heating (a) with part of (b) to give a prepolymer, adding the remainder of (b), (c) and (d) to the prepolymer, and then heating the mixture to effect additional polymerization of (a), (b), (c) and (d). The shaped polymeric material has enhanced tear strength, tensile strength and elongation, reduced permanent set and low toxicity, and suitable for parts for which high stretchability is required.
摘要:
An image reconstruction method for a magnetic resonance imaging device is disclosed, by which phase distortions of a magnetic resonance signal are stored in the form of a table prepared previously, by using a phase encode amount and an imaging region size as parameters; the phase distortions of the magnetic resonance signal are corrected on the basis of the phase distortions stored in the table for the measured magnetic resonance signal or the phase distortions varying for every line are presumed from the difference in the phase between the phase of hypothetical data including no phase distortions and the phase of measured data; and the phase distortions of the measured magnetic resonance signal are corrected by using this presumed value.
摘要:
Method of determining stereoscopic geometry of an object through photometric stereoscopic measurement with high accuracy. Three or more images of the object picked up in a same fixed direction by varying the state of light sources are derived. Relationships among the images are corrected so that an evaluation function determined by making use of redundancy of the images assumes a minimum value, to thereby prepare a reflectance map to be used in determining orientations of surface elements of the object. Through integration of the orientations, the surface shape of the object is determined. The method is applicable to the image processing in a scanning electron microscope.
