摘要： A control device for adjusting an amount of fuel to be supplied to a gas turbine based on a rotational speed of the gas turbine, such that a frequency of electric power output by a power generator that generates electric power using the gas turbine is within a given range, includes a load value acquisition unit configured to acquire a load value that is a value of a load applied to the power generator after cutoff of a part of the load applied to the power generator when the part of the load applied to the power generator is cut off, an arithmetic unit configured to calculate an adjusted value that is a value of the load different from the load value by carrying out an arithmetic operation on the load value and a bias, and a command unit configured to adjust the amount of fuel by outputting a first signal for causing the power generator to output electric power corresponding to the adjusted value.

摘要： Provided are a machining device (10), a machining unit, and a machining method that irradiate a workpiece (8) with a laser beam to perform cutting or boring machining of the workpiece (8). The invention has a laser output device (12), a guiding optical system (14) that guides a laser beam, and an irradiating head (16) that guides a laser beam and irradiates the workpiece (8) with the laser beam. The irradiating head (16) integrally rotates a first prism (52) and a second prism (54) with a rotation mechanism, thereby rotating a light path of the laser beam around a rotational axis of the rotation mechanism and irradiating the workpiece (8) while rotating the position of irradiation to the workpiece. A control device (22) calculates an allowable rotational frequency range of the laser beam on the basis of the relationship between an allowable thickness of a remelted layer of the workpiece (8) and a rotational frequency, or the relationship between an allowable thickness of an oxidization layer of the workpiece and the rotational frequency, determines a rotational frequency included in the allowable rotational frequency range as the rotational frequency of the rotation mechanism, and rotates the rotation mechanism at the determined rotational frequency, thereby enabling high-precision machining to be performed with a simple configuration.

摘要： A pressurized air supply system supplies, to a pressurization object device, flowing air that includes at least one of compressed air, which is generated by compressing air supplied from an air supply source, or discharged air from a turbocharger compressor forming a turbocharger. The compressor is controlled such that a saturated steam temperature of the flowing air supplied from the air supply source to the pressurization object device is lower than a temperature in the pressurization object device, at startup.

摘要： Provided are a diagnosing device, a diagnosing method, and a program with which it is possible to detect abnormalities accurately even if there is a small amount of data or the number of data points varies. This diagnosing device is provided with a Mahalanobis distance calculating unit which calculates the Mahalanobis distance (referred to as ‘MD value’ hereinbelow) of a detected value, and an abnormality determining unit which determines the presence or absence of an abnormality on the basis of the MD value, wherein the abnormality determining unit determines the presence or absence of an abnormality by arranging that a determination that there is no abnormality is more likely to occur if the number of samples per unit space is small than if the number of samples per unit space is large.

摘要： In a processing method for a ceramic-based composite material in which the ceramic-based composite material is molded by layering sheets obtained by impregnating reinforced fibers with a slurry containing ceramic powder and calcining the sheets after curing, the processing method includes a step of layering the sheets in a layering direction to form a laminate, and a step of covering the laminate with a vacuum bag and evacuating the inside of the vacuum bag to mold a cured laminate. In the step of molding the cured laminate, a slurry-removing material configured to absorb excess slurry is disposed with respect to the laminate, and a degassing circuit member provided on at least one side of the laminate and configured to discharge air bubbles generated inside the laminate is disposed with respect to the laminate.

摘要： Provided is a shaping method for shaping a laminated body of multi-layered sheet materials containing reinforcing fibers by using a shaping die. The shaping die has a curved portion formed in a convex shape over a predetermined direction. The shaping method includes: fixing, to the shaping die, a holding member configured to cover the laminated body over the predetermined direction to maintain a state where the laminated body is pressed against the curved portion; sealing the laminated body and the holding member to the shaping die by a sealing member to form a closed space; and depressurizing the closed space to thin the laminated body by sucking air of the closed space, and the fixing fixes the holding member to the shaping die such that the holding member does not come into contact with an end face on one side in the predetermined direction of the laminated body.

摘要： This turbine stator vane extends in the radial direction which intersects the flow direction of steam, and includes a pressure surface facing the upstream side in the flow direction, and a suction surface facing the downstream side in the flow direction. A plurality of grooves are formed in at least the pressure surface, the grooves extending outward in the radial direction toward the downstream side. At the periphery of the grooves in the pressure surface, formed is a hydrophilic uneven region having greater hydrophilic properties than the pressure surface. The downstream-side ends of the plurality of grooves are connected to slits for capturing a liquified component of the steam.
