An impact sensing laminatehas a first surfaceon which an impact force acts; a second surfacebrought in contact with a protection object OBJ; an impact absorption layerand a first pressure-sensitive layer. When a direction heading for the second surface from the first surface is defined as a first direction, the first pressure-sensitive layer is in the first direction from the impact absorption layer. The first pressure-sensitive layer is a layer of sensing a first impact force as the impact force to have been attenuated by the impact absorption layer.

Impact sensing laminate, impact sensing method and protection object inspecting method

A supersonic inspection jig has an insertion sectioninserted into a holeof an inspection target, and a flange sectionconnected with the insertion sectionand contacting the inspection target. The flange sectionhas a flange section first surfacewhich is a surface on the side contacting the inspection targetand a flange section second surfacewhich is a surface on the side contacting the probe. A position limiting sectionis provided on the flange section second surfaceto limit the position of the probeso that the probeis maintained in a position separate from a central axis C of the hole. Thus, the inspection around the hole becomes easily executable.

Supersonic inspection jig and supersonic inspection method

An ultrasonic flaw detection jig includes a base section with which a probe of the ultrasonic inspection apparatus is brought into contact; and a prominence section provided for the base section and inserted into an inspection object hole of an inspection object. The inspection object hole includes a countersunk section connected with a main surface of the inspection object and extending from the main surface while reducing a diameter; and a connection section connecting a bottom of the countersunk section and the rear surface of the inspection object. The prominence section has a conical shape corresponding to the shape of the countersunk section.
