摘要:
A novel enzyme of bilirubin oxidase and a conventional enzyme of laccase are found to oxidize bilirubin to biliverdin without formation of hydrogen peroxide, thereby permitting the content of conjugated bilirubin in biological fluid to be quantitatively determined by reacting therewith the bilirubin oxidase of a microorganism of genus Myrothecium origin, and also permitting the content of total bilirubin in biological fluid to be quantitatively determined by reacting therewith such a bilirubin oxidase or laccase in the presence of a specific additive compound.
摘要:
A novel enzyme of bilirubin oxidase produced by a genus Myrothecium or genus Coprinus origin microorganism and a conventional enzyme of laccase are found, in the presence of a specific additive compound, e.g. a surface active agent, aromatic carboxylic acid, sulfa drug or protease, to oxidize both conjugated and unconjugated bilirubin in biological fluid to biliverdin without formation of hydrogen peroxide, such that in the case of conventional enzymatic methods of the quantitative determination of glucose, cholesterol, neutral fats, free fatty acids, phospholipids or uric acid all existing together with bilirubin in biological fluid, the usual interference with such determination, as otherwise caused by bilirubin coexisting in such fluid, can be prevented by adding such a bilirubin oxidase or laccase together with such a specific additive compound to the determinative reaction system.

Driving techniques are provided for achieving a sufficiently low-speed drive and smooth change in the drive speed. Voltage is applied to an electromechanical element by repeating an output cycle in which one voltage value out of a first voltage value is output during a first period, a second voltage value lower than the first voltage value is output during a second period, a third voltage value lower than the second voltage value is output during a third period, and finally the second voltage value is output during a fourth period. Further, a mechanism for changing the lengths of the respective periods is provided to allow for a sufficiently low-speed drive and smooth change in the drive speed.

The present invention provides a seasoning apparatus capable of evenly seasoning each individual article, without seasoning any too heavily or too lightly. Therein, a screw having a helical blade is installed in a tube. The helical blade provides partitions that are provided upright between an article supply port and a discharge port. An article group, before seasoning, is accommodated in a section partitioned by the partitions, the motor rotates the screw, and the article group is transported from the supply port to the discharge port. Therein, each article group is transported to the discharge port separated from other article groups, and each individual article in the article group is seasoned evenly with the same seasoning processing time and the same seasoning supply ratio. In addition, the constitution of the seasoning apparatus is simplified because the screw simultaneously serves the two functions of separating and transporting the article groups.

An art of a driving device for appropriately improving a response of an SMA actuator will be provided. A portable telephone 1 has an image stabilization system 10 for driving an image pickup unit 9 by a pair of driving members 15a and 15b functioning as actuators, thereby performing image stabilization. Driving members 15a and 15b are formed as a wire of shape memory alloy (SMA) and when a voltage is applied to both ends and a current is supplied, driving force is generated in the contraction direction. With respect to the wire diameter of the SMAs, the wire diameter of the SMAs is set between 10 μm and 80 μm, thus the mountability and response are improved appropriately.
