Abstract: A detection signal from a multi-wavelength detector provided in a liquid chromatograph is stored in a data storage part, and a chromatogram is formed from the stored data with respect to a specific wavelength, to detect a peak from the chromatogram. The spectrum at a top of the peak to be identified or a known spectrum of a component to be identified is used as a reference spectrum, to calculate the degree of coincidence between the spectrum at each position of the chromatogram peak and the reference spectrum as fraction purity at each position of the chromatogram peak. The calculated fraction purity values are classified in colors, for example, and displayed on a display part. Thus, it is possible to readily decide whether the measured peak consists of a single component or at least two components, and which time range consists of a single component.

Abstract: The heart valve prosthesis comprises a substantially annular valve body having leaflets pivotally mounted to the valve body to be pivotable between respective open positions, in which blood is permitted to pass through the valve, and respective closed positions in which blood flow through the valve is substantially inhibited. The valve body is constructed of at least two part-annular elements and each respective leaflet is provided with at least two spaced pivot formations, each arranged to engage with a respective complementary pivot formation provided on a different part annular element. The annular body is assembled from the sub-elements and secured around the leaflets to provide a rigid annular body without the need for deformation or deflection of the annular body on assembly.

Abstract: A card processing device for processing data on a card comprising a processor configured to move along with the card and process data on the card as it is moving, a detection device which detects the displacement of the processor relative to the card in a manner which is directly dependent on the movement of either the card or the processor, and a converter device which converts the signal from the detection device to a reference signal for the processing of the data.

Abstract: The present invention is biocompatible polymer containing the copolymerization product of a mixture of hydrophobic and hydrophilic acrylic and/or allelic monomers, graft-polymerized with telo-collagen. The present material is useful in the production of deformable lenses, for example, intraocular lenses, refractive intraocular contact lenses, and standard contact lenses useful, for example, for correcting aphekia, myopia and hypermetropia.

Abstract: In an atomic absorption spectrophotometer utilizing the direct Zeeman's method, plural lamps are installed in the light source unit in order to enhance the versatility and enable continuous analyses. Accordingly, a plurality of low pressure discharge tubes 14 and hollow cathode lamps 16 in total are mounted on a lamp holder 12 of the light source unit, and by rotating the lamp holder 12, an arbitrary lamp may be positioned at the light source position for measurement. When the low pressure discharge tube 14 is used as the light source, in order to perform background correction by the Zeeman's method, a permanent magnet or an electromagnet 24 for operating a magnetic field on the light source is disposed, and a polarizing unit 26 is disposed on the measurement optical path, so that the direction of polarization of the measurement light to be sent to an atomizing unit 26 is changed over between the atomic absorption measurement mode and the background correction mode.

Abstract: An inorganic carbon removing part defined by has a double tube structure formed by an inner tube of polytetrafluoroethylene having continuous pores and an outer tube of resin. An acidified sample solution is guided into the inner tube and an alkalified sample solution is guided into the outer tube, and inorganic carbon contained in the acidified sample solution is outwardly moved toward the alkalified sample solution to be removed. The acidified sample solution, from which inorganic carbon is removed, is injected into a combustion tube, so that a carbon component contained in the sample solution is converted into carbon dioxide and detected by a detecting part. Since the alkalified sample solution contains purgeable organic carbon components of the same concentration as the acidified sample solution, the content of total organic carbon is correctly measured with no loss of the purgeable organic carbon components.

Abstract: A device for measuring the speed of an object. The device includes a spatial filter scheme to provide quick-response photodetectors and an efficient use of light. The device projects light onto the object by a light source 1, and the light reflected by the object is received by a lens. This light passes through aperture stop 4 and strikes prism array 7, where it is split alternately into two paths at a fixed pitch with respect to the optical axis. The two split beams are received respectively by two photodetectors. The speed of the object moving relative to the measuring device can be calculated based on the data collected by photodetectors.
