Abstract: The purpose of the present invention is to provide a novel stereoselective method for preparing a cyclic dinucleotide derivative and a production intermediate therefor, which can be used for an antibody-immunostimulant conjugate. Also provided is a method for producing a cyclic dinucleotide-linker and an antibody-immunostimulant conjugate while using the above production method. Further provided is a method for preparing a cyclic dinucleotide derivative, the method including the step of subjecting a compound (I) and a compound (IV) to stereoselective condensation using an optically active phosphitylating agent (Rc-II) or (Sc-II).

Abstract: The hybrid power generation system includes a renewable energy power generation device and a rotary power generation device connected to a common alternating-current power system. In the system, if renewable energy or an output fluctuates, a correction value calculated based on the fluctuation amount is added to a control parameter as a feedforward component, controlling the rotary power generation device.

Abstract: In a marine hybrid system which includes an engine, an electric motor, a thrust generation device, and a clutch mechanism configured to be able to switch connection states therebetween, if it is determined that the engine is in an overload condition, the clutch mechanism is controlled such that a load of the engine is reduced.

Abstract: A filter capacitor accumulating direct-current power and a semiconductor device module performing a switching operation that converts the direct-current power accumulated in the filter capacitor to alternating-current power are electrically connected with each other through a laminated bus bar. The laminated bus bar has a first bus bar and a second bus bar in which a plurality of connection conductors are laminated through an insulator. The second bus bar is provided with heat radiating portions that are formed by exposing a part of the conductor in each flat plate surface.
