摘要:
The biosensor has an electrode system for electrochemically measuring 1,5-anhydroglucitol (1,5-AG) and a reagent layer formed on said electrode system. The reagent layer contains an enzyme for measuring 1,5-anhydroglucitol, phenothiazine compounds, a stabilizer selected from a group of compounds comprising metal salts, organic acids, and amino acids, and an acidic polymer compound as an optional ingredient. The biosensor has excellent storage stability and can electrochemically measure 1,5-anhydroglucitol unaffected by the hematocrit contained in a whole blood sample.

A process and an apparatus for producing silicon carbide consisting mainly of .beta.-type crystal are disclosed. The fine silicon carbide consisting mainly of .beta.-type crystal is produced by charging the starting material of silica and carbon with a mole ratio of C/SiO.sub.2 of 3.2-5.0 into a top portion of a vertical-type reaction vessel having a preheating zone, a heating zone and a cooling zone in this order, descending the starting material by gravity through the reaction vessel, heating the starting material in the heating zone at a temperature of 1,600.degree.-2,100.degree. C. by electrically indirect heating in horizontal direction to effect the formation of SiC, cooling the resulting reaction product in the cooling zone under a non-oxidizing atmosphere, and recovering the cooled product from the bottom portion of the reaction vessel to obtain a product having a composition ratio by weight of silicon carbide, silica and free carbon which lies within the area represented by the area ABCD shown in FIG. 1 of the accompanying drawings.

Intended is to provide a mixed flow turbine or a radial turbine, which can suppress an abrupt increase in a load to be applied to the front edge portion of a blade, thereby to reduce an incidence loss. The mixed flow turbine or the radial turbine comprises a hub (3), and a plurality of blades (7) arranged at substantially equal interval on the outer circumference (5) of the hub (3) and having a warpage (23) curved convexly in the rotating direction, as entirely viewed from the front edge side to the back edge side. Each blade (7) is provided, at its front edge portion, with an inflection point (K), at which the warpage (23) in the section along the outer circumference is curved concavely in the rotating direction.
摘要:
By a method for measuring 1,5-anhydroglucitol, comprising the steps of: eliminating or converting glucose interfering with the measurement of 1,5-anhydroglucitol and/or a derivative thereof beforehand; and measuring 1,5-anhydroglucitol performed thereafter, wherein such glucose and/or a derivative thereof are/is eliminated or converted in whole blood as such without performing blood cell separation, an enzyme for measuring 1,5-anhydroglucitol is allowed to act on without performing blood cell separation, and 1,5-anhydroglucitol is electrochemically measured, it becomes possible to measure 1,5-anhydroglucitol using a small amount of whole blood without resort to a centrifuge or the like. Accordingly, this measurement method can be applied to rapid measurement of 1,5-anhydroglucitol at bedside or in a medical examination room or to home self-measurement thereof by a patient.

A phase control circuit includes a controlled voltage source circuit and a controlled current source circuit receiving a reference frequency signal, a first impedor connected between the controlled voltage source circuit and an output terminal of the phase control circuit, a second impedor connected between a DC power source and the output terminal, and an output control circuit connected between the output terminal and the controlled current source circuit. The oscillator circuit comprises a crystal oscillator, a circuit for amplifying the output of the oscillator and a circuit arrangement almost similar to the phase control circuit in which the reference frequency signal is supplied from the crystal oscillator. The phase control circuit and the oscillator circuit are suited for an integrated circuit construction.
