Abstract: An on-demand control system that supplies power to electric devices based on not predetermined priorities fixed to electric devices, but based on priorities changed according to the use status of the user. The on-demand control system can control supply of power of a commercial power source in real time in response to a power request necessary for the user and controls the supply of power according to the QoL necessary for the user through daily life. The on-demand power control system is a multiple power source management system for an on-demand power control system.
Abstract: Portable turntables or rotation platforms built by assembly enable rotation of vehicles and/or loads of significant size and/or weight. The portable turntables or rotation platforms are highly effective and efficient with respect to materials, construction and environmental impact.
Abstract: A transmission probe and a reception probe for transmitting and receiving a wideband ultrasonic wave are provided. Each time when the locations of the probes and are moved, a received wave Gj(t) is obtained. Based on a spectrum Fj(f) corresponding to the received wave Gj(t), a narrowband spectrum FAj(f) is extracted. A component wave GAj(t) corresponding to the narrowband spectrum FAj(f) is found by inverse Fourier transformation. A longitudinal wave primary resonance frequency f1 having a relationship with a thickness W (mm) of an inspection target and a primary resonance frequency fS1 of a transverse wave generated by mode conversion are calculated. A comparative display of the component waves GAj(t) is presented using f1, fS1 and sizing coefficients ns1, ns2, ns3 and ns4 for high precision inspection.

Abstract: A flaw Z with a long probing length inside a probing target is allowed to be probed. The waves other than the probing target waves are removed or reduced, so that the individual difference in the sizing result due to the ability of the measuring personnel is eliminated to improve the precision of the probing. A transmission probe 31 and a receiving probe 32 for transmitting and receiving a wide band ultrasonic wave are included. Each time the positions of the probes 31 and 32 are moved, a received wave Gj(t) is obtained. From a spectrum Fj(f) corresponding to the received wave Gj(t), a narrowband spectrum FAj(f) is extracted. A component wave GAj(t) corresponding to the narrow band spectrum FAj(f) is obtained by inverse Fourier transformation. The component wave GAj(t) is provided for a comparative display using a predetermined sizing coefficient.
