≪１級課題 -電気・電子工学-≫【問 1】[Claim 1]
A satellite comprising a Doppler compensation circuit, the Doppler
compensation circuit comprising:a Doppler estimation unit that acquires a received power
level of a received wave and a time variation of the received power level andthat performs a process of deriving a Doppler frequency of the satellite on thebasis of the received power level of the received wave and the time variationof the received power level to output the Doppler frequency as an estimatedDoppler frequency, anda multiplication unit that multiplies a signal of the estimatedDoppler frequency and a signal of a local frequency for demodulation, thus
offsetting the local frequency by the estimated Doppler frequency.
[Claim 2]
The satellite according to claim 1, wherein the Doppler estimation
unit
acquires the received power level of the received wave and thetime variation of the received power level;
uses, as fixed parameters, the speed of light, a position of atransmitting station, a carrier wavelength λ, a transmission equivalentisotropic radiant power, and a receiving antenna gain Gr;
calculates the Doppler frequency of the satellite in accordancewith the received power level of the received wave and the time variation of
the received power level; andoutputs the Doppler frequency to the multiplication unit as
the estimated Doppler frequency.
[Claim 3]
The satellite according to claim 1, wherein the Doppler estimation
unit
acquires the received power level of the received wave and thetime variation of the received power level,refers to reference information including candidates for theestimated Doppler frequency, the candidates for the estimated Dopplerfrequency being prepared in advance in association with the received powerlevel,
calculates the candidates for the estimated Doppler frequency
on the basis of the acquired received power level of the received wave,
selects the estimated Doppler frequency from the candidates
on the basis of the time variation of the received power level, andoutputs the estimated Doppler frequency to themultiplication unit.
【問 2】
A fuel cell device that includes a fuel cell capable of generating powerfrom a fuel gas (e.g., a hydrogen-containing gas) and an oxygen-containinggas (e.g., air) has recently been proposed as a next-generation energy source.
A power conditioner is used in a power generation system for a fuelcell device which is a distributed power source to supply power to a load incooperation with a system power supply. The power conditioner has various
functions such as an inverter function of converting a direct current output
from the fuel cell device into an alternating current and a control function ofcontrolling the cooperation with the system power supply.
The power conditioner supplies power generated in the fuel cell
device to the external load in cooperation with the system power supply. At
this time, the power conditioner increases or decreases the output power so
as to prevent backfeeding to the system, thereby outputting the power
according to a power requirement of the external load. As the output powerfrom the power conditioner to the external load increases, an output current
from the fuel cell device to the power conditioner decreases. When the fuelcell device detects the decrease in output current, the fuel cell deviceattempts to increase the amounts of oxygen gas and fuel gas to be supplied to
the fuel cell, by controlling the operation of auxiliary machinery to increase
the amount of power generation. It is, however, difficult to instantaneously
increase the amounts of oxygen gas and fuel gas. The fuel cell device
consequently develops a state of insufficient oxygen gas and fuel gas forpower generation. Power generation in the state of insufficient oxygen gas
and fuel gas causes damage to the fuel cell, resulting in problems such as anincreased possibility of failure of the fuel cell device and a reduction inservice life of the fuel cell device.

【問 3】The business bird's eye view BV, which will be described later indetail, is a bird's eye view that abstracts and illustrates an overall image ofbusiness to be systematized, with figures that indicate "events", "cores", andtheir relationships, thereby illustrating the entire business of a company in amacro manner and in a form understandable by plural persons. When acore business application is constructed, the pre-processing engine 100 has arole of clearly identifying work and objects in the core business anddescribing them in the form of a business bird's eye view.
The SVO list E1 is a list that displays the type of operations
conducted on the operation objects by the roles on the scenario chart. TheSVO list E1 is a list expanded with the same granularity as that of the roles
on the scenario chart D4. In other words, it is a list that sorts out, as its
granularity, "functions" obtained by systemizing the roles on the scenario
chart D4. Further, the activity definition E2 is a definition related to aprocess (step) for completing the roles on the scenario chart D4.
