摘要： PROBLEM TO BE SOLVED: To enhance flaw detection performance significantly by irradiating a hook part, where a flaw appears most frequently, accurately with an ultrasonic wave regardless of fluctuation in the coordinate of probe position in a scanning mechanism for automatically scanning an ultrasonic probe and converging the flaw detection ultrasonic wave to that part thereby enhancing the S/N ration. SOLUTION: The ultrasonic flaw detector comprises a probe array 1 having function for converging an ultrasonic wave to the vicinity of saddle hook part 14 at the forward end of turbine rotor by electronically controlling a plurality of arranged micro oscillators, a probe 2 for projecting ultrasonic wave vertically to the saddle part at the forward end of turbine rotor integrated with the probe array 1, and a controller 6 for automatically maximizing the signal.

摘要： PROBLEM TO BE SOLVED: To accurately detect a defective part without being restricted by the shape of a blade built-in part. SOLUTION: Supersonic waves from a probe 7 for detecting flaw are applied from the base part side surface side of a blade leg part 33a toward a boundary position 12 where a blade built-in parts are adjacent one another, are reflected by the end face of an adjacent saddle type part 32 and are directed toward a protrusion 32b for detecting the presence of a defective part 10. As compared with a conventional technique for applying ultrasonic waves from the base part side of the saddle type part 32a in a turbine rotor 30, reflecting the supersonic waves by the tip of the saddle type part 32a, and hence detecting a defective part, ultrasonic waves can be positively applied to the protrusion 32b without being affected by the geometrical shape and dimensions of the wheel base part side and the blade built-in part and hence the defective part 10 can be detected accurately.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that in former energy-saving service a user and a service provider cannot necessarily receive merit of energy-saving because initial investments by a contractor (for example, a user of an electric power facility) are necessary and an energy-saving service provider guarantees the target value of energy-saving to the user.
SOLUTION: A present electric power consumption of a target load facility of a user, who owns the target load facility and who desires to save energy, is obtained. An energy-saving support service provider installs an inverter or an inverter and a motor etc. at the target load facility, performs a motor speed control operation by the inverter, obtains the merit-charge based on the difference between present electric power consumption and electric power consumption by the inverter control operation, and distributes the merit-charge reflecting the merit-charge to the content previously decided between the user and the energy saving service provider.

摘要： PROBLEM TO BE SOLVED: To obtain a seabed sedimentary layer parameter-estimating device for stably estimating the value of parameters for indicating the characteristics of a seabed sedimentary layer from actual measurement data. SOLUTION: An observation characteristic value operation part 2 obtains a characteristic value C0 of an elastic wave being propagated on a seabed sedimentary layer from data obtained by observing the target seabed sedimentary layer. A gene operation part 10 performs a genetic operation to an individual by a genetic algorithm with the combination of the candidate values of a plurality of parameters for indicating the physical characteristics of the seabed sedimentary layer as the individual to allow it to evolve into a next-generation individual. An estimation characteristic value operation part 4 estimates a characteristic value C of an elastic wave theoretically for the individual. A degree-of-conformance operation part 3 obtains the degree of conformance for indicating the degree of conformance between a characteristic value C and the characteristic value C0 and sets a candidate for composing an individual with the highest degree of conformance as the solution of the value of parameters.
