【問１】
1.

An artificial satellite, comprising:a Doppler compensation circuit including:a Doppler estimation unit that acquires a received power level of areceived wave and a time variation of the received power level, and derives a Doppler
frequency of the satellite based on the received power level of the received wave and thetime variation of the received power level to output the Doppler frequency as an
estimated Doppler frequency; anda multiplication unit that, by multiplying a signal of the estimatedDoppler frequency and a signal of a local frequency for demodulation, offsets the local
frequency by the estimated Doppler frequency.
2.

The artificial satellite according to claim 1, wherein the Doppler estimation

unit acquires the received power level of the received wave and the time variation of thereceived power level, treats a speed of light, a position of a transmitting station, acarrier wavelength λ, a transmission equivalent isotropic radiant power, and a receiving
antenna gain Gr as fixed parameters, and calculates the Doppler frequency of thesatellite to output the Doppler frequency of the satellite to the multiplication unit as theestimated Doppler frequency based on the received power level of the received wave andthe time variation of the received power level.
3.

The artificial satellite according to claim 1, wherein the Doppler estimation

unit acquires the received power level of the received wave and the time variation of thereceived power level, refers to reference information in which estimated Doppler
frequency candidates prepared in advance in association with the received power level
are recorded, calculates a candidate for the estimated Doppler frequency based on theacquired received power level of the received wave, selects an estimated Doppler
frequency from within the candidates based on the time variation of the received power
level to output the estimated Doppler frequency to the multiplication unit.

【問２】In recent years, as a next-generation energy, a fuel battery device including afuel battery cell that can obtain electric power using a fuel gas (hydrogen-containinggas) and an oxygen-containing gas (air) has been proposed. A power conditioner isused in a power generation system in order for the fuel battery device, which is a
distributed power source, to supply power to a load in cooperation with a system powersource. The power conditioner has various functions such as an inverter function forconverting a direct current output from the fuel battery device into an alternating
current and a control function for performing interconnection control with the system
power source.
The power conditioner cooperates with the system power supply to supply theelectric power generated by the fuel battery device to the external load. At this time,
the output power is increased or decreased so as not to generate a reverse power flow to
the grid, thereby outputting the power according to a power request from the externalload. When the output power from the power conditioner to the external load increases,
the output current from the fuel battery device to the power conditioner decreases.
When the fuel battery device detects this decrease in output current, the fuel battery
device attempts to increase the amount of power generation by increasing the amount ofoxygen gas and fuel gas supplied to the fuel battery cells by controlling the operation of
the auxiliary machinery.

However, it is difficult to instantaneously increase theamounts of oxygen gas and fuel gas, and a state in which oxygen gas and fuel gas for
power generation are insufficient will occur in the fuel battery device.

Power

generation in the state where the oxygen gas and the fuel gas are insufficient causes
damage to the fuel battery cell and arises problems such as increasing the risk ofdamage to the fuel battery device, and shortening the service life of the fuel battery
device.

【問３】The business bird's-eye view BV, which will be described later in detail, is an
overall view of the business to be systemized, abstracted by the "events", "cores", andfigures showing their relationships, and is a bird's-eye view of the entire business of acompany in a macro manner and in a form that can be understood by multiple people.
The pre-processing engine 100 has a role of clearly identifying the business and thetarget during the core business when constructing the core business application andexpressing the business and the target in the form of a business overhead view.
The SVO list E1 is a list that displays what operations the roles on the scenario
chart perform on the operation target. The SVO list E1 is a list that expands with thesame granularity as the roles on the scenario chart D4, in other words, with the“function” when systematizing the roles on the scenario chart D4 as granularity.
Further, the activity definition E2 is a definition regarding a process (step) forcompleting a role on the scenario chart D4.
