摘要:
A fuel cell device is improved for operating conditions during a partial load operation. The fuel cell device comprises a cell stack formed by electrically connecting fuel cells for generating power by fuel gas and oxygen-containing gas; a fuel gas supply unit for supplying the fuel gas to the fuel cells; and a power adjustment unit for adjusting the amount of current that is supplied to an external load and a controller for controlling the fuel gas supply unit and the power adjustment unit. The controller adjusts, during the partial load operation of the fuel cell device and when the fuel gas supplied to the cell stack is at low flow rate. The a relationship between a fuel utilization rate of the cell stack and the amount of power generated by the cell stack can be nonlinear.

The present invention provides a data collection device that lightens a registering workload for an administrator and prevents that a set of procedures for a data collection is started later than a registered start time. A data collection device 101 comprises: a database 105 in which start times of the sets of the procedures have been previously registered; and a registration control unit operable, if a received specified time is the same as any of the previously registered start times, to search and retrieve a time that is different from any of the previously registered start times in association with a new set of the procedures, instead of registering the specified time.

An electronic apparatus includes a display portion, a main body portion, an articulated coupling mechanism, and an interlock mechanism. The display portion includes a display screen. The main body portion is coupled to the display portion. The articulated coupling mechanism includes, at each of end portions, a plurality of coupling members each having a rotation axis and being rotatably coupled to one another in series about the rotation axis, the plurality of coupling members coupled in series having one end coupled to the main body portion side and the other end coupled to the display portion side. The interlock mechanism interlocks rotations of the plurality of coupling members with one another in the articulated coupling mechanism.
摘要:
A method for obtaining a star polymer having a controlled ratio of a weight average molecular weight of the star polymer to a number average molecular weight of the star polymer, containing the steps of anionically polymerizing a (meth)acrylic ester having an alicyclic skeleton and a lactone ring in the presence of an anionic polymerization initiator to synthesize an arm polymer, reacting the arm polymer with a polyfunctional coupling agent, and reacting with an anionic polymerizable monomer.
摘要:
A method for quantitatively determining LDL cholesterol, including the steps of adding to serum a surfactant selected from among polyoxyethylenealkylene phenyl ethers and polyoxyethylenealkylene tribenzylphenyl ethers and a cholesterol-assaying enzyme reagent so as to preferentially react cholestrols in high density- and very low density-cholesterols among lipoproteins, and subsequently determining the amount of cholesterol that reacts thereafter. This method can eliminate the necessity for pretreatments such as centrifugation and electrophoresis, enables the quantitative determination to be conducted in an efficient, simple manner, and can be applied to various automatic analyzers.
