A diagnosis apparatus (100) includes a fiber optic sensor (118), a collection processor (132), and a self-diagnosis processor (136). The fiber optic sensor (118) is configured to be disposed over a target (TG). The collection processor (132) is configured to perform a collection process that collects measurement data related to the target (TG) obtained by the fiber optic sensor (118). The self-diagnosis processor (136) is configured to perform a self-diagnosis process before the collection processor (132) starts the collection process. The self-diagnosis process obtains an output value related to calibration of the fiber optic sensor (118), causes the collection processor (132) to start the collection process when the output value falls within a proper range, and outputs an error when the output value falls outside the proper range.

A fastening tool for fastening a nut to a bolt includes a pipe and a coupling member. The nut breaks at specified torque. The pipe has a socket wrench, a detachable structure and a suction port. The detachable structure is for attaching to and detaching from a rotor of a rotational drive device. The suction port is for suctioning a piece of the nut broken by the specified torque. The coupling member has a flow path, a first coupling portion and a second coupling portion. The flow path is for suctioning the piece of the nut from the suction port. The piece of the nut is suctioned from the suction port with an ejector. The first coupling portion couples the coupling member to a casing of the rotational drive device. The second coupling portion couples the coupling member to a duct of the ejector.

According to one embodiment, a positioning device (2) positions a hole inspection device (1) to a hole (H) formed in an object (O). The positioning device (2) includes a guide unit (12) and a detachable member (13). The guide unit (12) has a positioning hole (14) and a flat supporting face (15). A cylindrical or columnar positioning member (21) is slidably inserted into the positioning hole (14). At least a tip of the positioning member (21) is inserted into the hole. A central axis of the positioning hole (14) and a reference line (RF) of the hole inspection device (1) for measuring or inspecting the feature of the hole (H) lie on a same straight line. The guide unit (12) is set by contacting the flat supporting face (15) to a surface of the object (O) surrounding the hole (H) or a flat surface of a jig (16) placed on the object (O). The detachable member attaches a part or all of the guide unit (12) to the hole inspection device (1).

A fiber placement apparatus for arraying prepreg tapes in a width direction, and laminating the arrayed prepreg tapes includes first rollers and a second roller. Each of the prepreg tapes is a material of a fiber reinforced plastic. The first rollers feed out the prepreg tapes one by one. The first rollers rotate around first rotation axes. The second roller arrays the prepreg tapes, fed out from the first rollers, in the width direction, and feeds out the arrayed prepreg tapes slidably. The second roller rotates around a second rotation axis lying on a skew position with respect to each of the first rotation axes. At least one first roller of the first rollers is provided with a first position adjustment mechanism configured to adjust a position of the at least one first roller in a first rotation axis direction of the at least one first roller.

A sealant application apparatus includes a seal gun, a distance meter, a moving mechanism and a controller. The seal gun has a nozzle for discharging sealant toward a fastener. The distance meter is fixed to the nozzle. The distance meter measures a distance from a measurement position to a surface of the sealant. The moving mechanism moves the seal gun relatively to the fastener. The controller controls the moving mechanism and the seal gun. The sealant is started to be discharged out from the seal gun in a state where the nozzle has been positioned to cover the fastener at a position away from a surface of the object by a predetermined distance. Subsequently, the sealant is applied to the fastener under a sealant application condition according to the distance measured by the distance meter while moving the nozzle away from the surface of the object.

A sensor position determination method determines an installation position of an electric field sensor that detects electric field strength generated on a surface of an airframe of an aircraft. The sensor position determination method includes: acquiring the electric field strength at each of candidate positions at determined relative pitch angle and relative roll angle by electrostatic field analysis; repeating the acquisition of the electric field strength at each of the candidate positions by changing at least one of the relative pitch angle and the relative roll angle, each time the at least one of the relative pitch angle and the relative roll angle is changed; and identifying a candidate position having a relatively large variance of the acquired electric field strength, and setting the identified candidate position as the installation position of the electric field sensor.
