Abstract: A tractor includes a working motor, a work machine including a roller configured to rotate by an output from the working motor, a support mechanism configured to support the work machine such that a working posture and a retracting posture are achievable, and a control device. The control device executes: an adherence amount acquisition process of acquiring an estimated adherence amount as an estimated value for the amount of mud attached to the roller; and a mud removal process of, when the estimated adherence amount is equal to or more than a determination adherence amount, removing the mud from the roller by driving the working motor in a state where the work machine takes the retracting posture.

Abstract: A personal digital assistant for supporting inspection of at least one device disposed in an inspection target area includes: an abnormality acquisition unit configured to acquire information about an abnormality in the at least one device; a guidance information storage unit configured to store guidance information which at least includes at least one response procedure for each abnormal event in the at least one device and information about response capability required to execute the at least one response procedure; and a display unit configured to refer to the guidance information stored in the guidance information storage unit, and display the guidance information for responding to an abnormal device which is the device where the abnormality is acquired by the abnormality acquisition unit.

Abstract: A visual recognition system configured to display an unreceived-signal sensor among a plurality of sensors that are inspection targets includes: a reception unit configured to be capable of receiving a sensor output transmitted from each of the plurality of sensors, the sensor output including identification information on the sensor; an unreceived-signal sensor identification unit configured to identify, among the plurality of sensors, the unreceived-signal sensor, the sensor output from which has not been received by the reception unit; and a display unit configured to display the unreceived-signal sensor identified by the unreceived-signal sensor identification unit, to be visually recognizable by a viewer.

Abstract: An inspection route plan proposal system includes: a damage risk calculation unit configured to calculate a damage risk for each of a plurality of apparatuses based on an inspection result for each of the plurality of apparatuses; an inspection required time calculation unit configured to calculate an inspection required time for each of the inspection items of each of the plurality of apparatuses based on the inspection work time for each of the inspection items of each of the plurality of apparatuses; and an inspection route plan presentation unit that presents an inspection route plan including an inspection target apparatus, an inspection execution item, and a total inspection required time required to execute inspection of the inspection execution item, the inspection route plan presentation unit being configured to be able to present a plurality of the inspection route plans, each inspection route plan having at least one of the inspection target apparatuses or at least one of the inspection execution i

Abstract: Provided is a non-invasive and prompt testing method, in which a mucus adhering onto the surface of a mucous membrane is used as a specimen. A method for collecting a specimen by wiping out a mucus adhering onto the surface of a mucous membrane, when the specimen is collected during an endoscopic examination.

Abstract: A film cartridge support in a photographic camera is provided in a film chamber which holds a film cartridge. The support includes a stopper for limiting the rotation of the film cartridge around a shaft of the film cartridge, and the stopper is supported for rotation in a direction approximately parallel to a surface of a film set on the camera. A modification of the support can include a block portion on the support extending across the lower end of the film chamber to prevent incorrect insertion of the film cartridge into the film chamber. A cut portion which is large enough to allow insertion of an operator's finger may be provided at the top end of the film chamber to allow easier insertion and removal of the film cartridge into and from the film chamber.
