An ultrasonic inspection system includes an ultrasonic sensor which includes a piezoelectric element to transmit and receive an ultrasonic wave and a calibration piece, and a control device. The calibration piece includes a propagation portion extending along an upper surface of the piezoelectric element, and a propagation redirecting portion which is formed on one side in an extending direction of the propagation portion, and is connected to the piezoelectric element through a heat resistant adhesive. The propagation redirecting portion includes a slope inclined in a vertical direction to the upper surface of the piezoelectric element. The propagation redirecting portion is configured to reflect the ultrasonic wave incident on the propagation redirecting portion from the piezoelectric element on the slope and emit the ultrasonic wave toward the propagation portion, and reflect the ultrasonic wave which is reflected on an end surface on the other side in the extending direction of the propagation portion and incident on the propagation redirecting portion from the propagation portion on the slope and emit the ultrasonic wave toward the piezoelectric element.

Ultrasonic inspection system

An ultrasonic inspection system includes an ultrasonic sensor and a control device. The ultrasonic sensor has a piezoelectric element that transmits and receives ultrasonic waves and plate portions and that are arranged so as to contact an upper surface of the piezoelectric element and have different thicknesses. The control device acquires a propagation time of a reflected wave reflected on an upper surface of the plate portion, calculates a sound velocity of the plate portion using the propagation time of the reflected wave and a thickness of the plate portion, and corrects a sound velocity of a pipe and acquires a sound velocity of the plate portion based on the calculated sound velocity. In addition, the control device acquires a propagation time of a reflected wave reflected on an upper surface of the plate portion, and calibrates a time axis based on the propagation time of the reflected wave, a thickness of the plate portion, and the sound velocity of the plate portion.

A game management device manages a game to be played by selecting with a touch operation, a selectable target from a plurality of selectable targets (for example, pitch types) displayed on a screen. A display control unit display the plurality of selectable targets (for example, a strike pitch location and a ball pitch location) on the screen. An area setting unit sets a plurality of parameter areas respectively corresponding to the plurality of parameters (for example, a strike location and a ball location) within the screen. When performing an operation of moving a selected target to one of the plurality of parameter areas, a parameter setting unit sets a parameter corresponding to the parameter area to which the selected target is moved, the selected target being selected from among the plurality of selectable targets with the contact operation.

An object of this invention is to sense a transient displacement of the blade position to thereby detect abnormalities early. The invention includes: one or more first sensors mounted so as to be removable from an outer surface of a casing opposed to blade tips; a second sensor for acquiring a signal from a fixed point on a rotor shaft of the blades; a section configured to extract data groups from an output signal of the first sensor on the basis of information acquired by the second sensor; a section configured to average the data groups; a section configured to determine thresholds from averaged data obtained under a healthy condition; and an assessing section configured to compare magnitude of the thresholds and sensor signals obtained during blade status monitoring. Since a transient displacement of blade position can be sensed, abnormalities can be detected early in this invention. This early detection, in turn, enables a rotation to be stopped during an initial phase of blade damage. The invention is therefore advantageous in minimizing impacts on other devices.
