Abstract: A non-transitory computer-readable storage medium storing a navigation monitoring program that causes at least one computer to execute a process, the process includes acquiring direction information that indicates a direction of a vessel and position information that indicates a position of the vessel; and predicting whether or not the vessel navigates along a course by inputting the acquired direction information and the acquired position information to a prediction model generated by machine learning by using direction information and position information for each of a plurality of vessels that has navigated in the past and a correct answer label that indicates whether or not each of the plurality of vessels navigates along a course.

Abstract: A rotation detector resists magnetic disturbances from sources near the detector. The rotation detector includes a rotor on which iron magnetic path changing pieces are fixed at predetermined intervals. A first bias magnet and a first magneto-resistive element for detecting the flux of the first bias magnet oppose the magnetic path changing pieces. A magnetic guide plate is located to guide disturbing magnetic flux in predetermined directions. The disturbing magnetic flux thus fails to adversely affect the first magneto-resistive element.

Abstract: A rotation detector includes a rotor having a shaft. Projections are located at predetermined intervals on the periphery of the rotor and extend in an axial direction. Magnets are located between the projections and the shaft. The flux of each magnet is detected by a corresponding magnetism detection element. Each magnetism detection element has magnetic resistors. Movement of the projections changes the direction of flux of the magnets. Each resistor is switched between a first state, in which its magnetic resistance is great, and a second state, in which its magnetic resistance is small, in accordance with the change of the flux direction. The resistors are divided into two groups. The groups are substantially symmetrical relative to a centerline of the groups such that, when the direction of the flux changes, the resistors in one group are in the opposite state from the resistors in the other group. The centerline of changes in the direction of the flux matches the centerline of the resistor groups.

Abstract: An uneven wear-resisting heavy duty pneumatic tire comprises main grooves continuously extending in a tread of the tire along a circumference thereof, land portions separated by the main grooves, and stepped zones each provided in the land. Each stepped zone has a surface located radially inside of the tread by a step a viewed sectionally. Each of said stepped zones is separated from the adajcent land portions via a pair of circumferentially extending grooves or narrow cuts. An uneven wearing-sacrificing portion is formed by the surface of the stepped zone. The uneven wear-sacrificed portion slide-contacts with the tread within the tread ground-contacting area for supporting the load exerted upon the tire.

Abstract: A pneumatic tire comprising a tread, wherein at least one circumferential groove having a width not greater than 0.1 times as much as that of the tread is formed in at least one end portion of the tread, thereby forming at least one narrow rib having a width not more than 0.2 times as much as that of the tread, and at least one of the above at least one narrow rib is projected radially outwardly from an extension line of a contour line of the tread by 0.3 times of a gauge of the tread at the maximum.

Abstract: An uneven wear-resisting heavy duty pneumatic tire comprises main grooves continuously extending in a tread of the tire along a circumference thereof, land portions separated by the main grooves, and stepped zones each provided in the land. Each stepped zone has a surface located radially inside of the tread by a step a viewed sectionally. Each of said stepped zones is separated from the adjacent land portions via a pair of circumferentially extending grooves or narrow cuts. An uneven wearing-sacrificing portion is formed by the surface of the stepped zone. The unever wear-sacrificed portion slide-contacts with the tread within the tread ground-contacting area for supporting the load exerted upon the tire.

Abstract: A pneumatic bias tire for off-road vehicles is disclosed. This tire comprises a bias-structured carcass composed of plural plies each containing organic fiber cords embedded in rubber. In the carcass, the inner plies located near the inner surface of the tire have a rubberized cord arrangement of a more slackened state as compared with the outer plies and further medium plies existent between the inner and outer plies.
