Abstract: An apparatus and a method for ultrasonic testing obtains high-resolution and high-S/N ratio testing results by driving a number of piezoelectric elements using fewer pulsers and receivers in comparison with the number of elements composing an array transducer. A sensor information setter sets a plurality of piezoelectric element groups used for transmission and a plurality of piezoelectric element groups used for reception among the plurality of piezoelectric elements composing an ultrasonic array transducer. A computer transmits an ultrasonic wave from the element cluster set for transmission, and stores an ultrasonic wave received by the element cluster set for reception. The procedure is repeated including different element cluster sets for transmission and reception to obtain first receive signals. The first receive signals are summed to obtain a second receive signal; and the second receive signal is displayed with reference to the sensor center position on a display unit.

Abstract: Hydrogen which has entered into a pressure/differential pressure transmitter from external or internally generated hydrogen and hydrocarbons are converted to air bubbles within pressure guide paths. As a result, the indicated value drifts and an accurate numerical value is not output. A pressure/differential pressure transmitter includes a space formed between a diaphragm and a main body side wall face, pressure guide paths connected to the main body side wall face, a sealed liquid sealed in the space and the pressure guide paths to transmit a pressure received by the diaphragm to a sensor, and a hydrogen absorption material provided at least in the sealed liquid, on the main body side wall face, or in a part of a path between the main body side wall face and the sensor to absorb hydrogen atoms in the sealed liquid.

The power-receiving device has a plurality of power-receiving coils distributively arranged in prescribed locations of the car to receive external electric power. The power-transmitting device has a plurality of power-transmitting coils arranged in prescribed locations outside of the electric car corresponding to the plurality of power-receiving coils to transmit electric power. The non-contact charging apparatus for a mobile body transmits electric power in a non-contact manner from the plurality of power-transmitting coils to the plurality of power-receiving coils and charges a secondary battery. Since a plurality of power-receiving coils are provided, electric power can be transmitted efficiently even when there are installation-space or installation-shape constraints.

Abstract: Ultrasonic inspection equipment facilitates alignment of display positions of three-dimensional ultrasonic inspection data and three-dimensional shape data, and quickly discriminates between a defect echo and an inner-wall echo. A computer 102A has a position correction function of correcting a relative display position between three-dimensional shape data and three-dimensional ultrasonic inspection data. A display position of the three-dimensional ultrasonic inspection data or that of the three-dimensional shape data is moved by a norm of a mean vector along the mean vector that is calculated from a plurality of vectors defined by a plurality of points selected in the three-dimensional ultrasonic inspection data and by a plurality of points selected in the three-dimensional shape data. The three-dimensional shape data and the three-dimensional ultrasonic inspection data are displayed in such a manner as to be superimposed on each other on a three-dimensional display unit 103C.
