Title: Process for producing poly (arylene sulfide)
Inventor: MIYAHARA MICHIHISA
IPC: C08G75/0254
Filed: 1997-02-14
Abstract: The invention provides a process for producing a poly(arylene sulfide) comprising a dehydration step of heating and dehydrating a mixture containing an organic amide solvent (a), an alkali metal sulfide and water to control a water content in the mixture and a subsequent polymerization step of subjecting the alkali metal sulfide and a dihalo-aromatic compound to a polymerization reaction in the organic amide solvent (a), wherein hydrogen sulfide vaporized off during the dehydration step is absorbed in another organic amide solvent (b) outside a system in which the dehydration step is carried out, thereby recovering it, and the hydrogen sulfide thus recovered is reused in the polymerization reaction as a raw material for the alkali metal sulfide.  The production process of the invention can solve various problems attendant upon the vaporization of hydrogen sulfide and provide a poly(arylene sulfide) which undergoes little variation in melt viscosity and has stable quality.

Title: Method and apparatus for osteoporosis diagnosis
Inventor: ISHII TETSUYA
IPC: A61B8/08
Filed: 1997-02-21
Abstract: An osteoporosis diagnosis apparatus provided with a two-dimensional ultrasonic transducer array (3) comprising a number of cells (11, 12, ...). The ultrasonic transducer array (3) is applied to the skin covering a predetermined bone of a subject, and the individual cells sequentially emit a predetermined number of ultrasonic pulses through the skin while receiving echoes from the bone. The received echo data are processed so that they can be handled in a planewave problem, from which the information on the reflection from the bone is determined. This information is processed to obtain the acoustic impedance of a cortical bone and a cancellous bone, so as to check for the presence of osteoporosis. The information on the reflection from the bone can also be handled as an eigen-value problem, and, when the information is handled in such a manner, the shape determination of a bone becomes unnecessary.

Patent CA-2230222-A1 (CA)
Title: Method and assembly for rapid measurement of cell layers
Inventor: WARDLAW STEPHEN C
IPC: B04B13/00
Filed: 1998-02-20
Abstract: Centrifuged material layer volumes are measured and quantified during centrifugation of the material layers. The material layers are differentially highlighted, preferably by means of one or more fluorescent dyes or stains which are admixed with the sample being analyzed. This kinetic quantification procedure is particularly useful in performing differential blood cell and platelet counts. The blood sample is centrifuged while being subjected to a strobed light source. At least one photometric cell layer compaction measurement is made in conjunction with the light flashes so as to record a degree of cell layer compaction as the sample is being centrifuged. In certain cases, after several successive cell layer compaction readings are derived, a compaction curve is identified and the ultimate degree of cell layer compaction is calculated from the derived compaction curve prior to the achievement of the ultimate degree of cell layer compaction. Preferably, a sample of anticoagulated whole blood contained in a transparent tube is centrifuged so as to gravimetrically separate the various blood cell and other components by specific gravity. The tube may contain an insert or float which serves to elongate certain of the separated component layers. The various component layers may be periodically measured during the centrifugation step by a linear image dissector which can detect differential fluorescence in the several component layers. The blood component layers are caused to fluoresce by flashes of light which are directed toward the blood sample tube as the latter is being centrifuged. The gravimetric separation and quantification of blood sample constituent layers are thus both performed while the sample remans in the centrifuge. The ultimate degree of constituent layer compaction may be measured during centrifugation directly, or it can be extrapolated from a plurality of sequential preliminary measurements which are made during centrifugation prior to ultimate compaction being achieved.
