Abstract: A ship vicinity information display device is provided, which is capable of displaying a position etc. of a destination of another ship based on information of the destination obtained from the other ship, in a mode which is intuitively easy to understand. A radar indicator may include a display unit, an AIS interface, and processing circuitry. The display unit may be capable of displaying an image of a situation in the vicinity of one ship. The AIS interface may receive the information of the destination of the other ship. The processing circuitry may acquire a longitude and latitude of the destination based on the destination information of the other ship and graphically display at least one of the position of the destination of the other ship and a direction of the destination from the other ship (other-ship destination symbol), on the display unit.

Abstract: Provided are a method for determining the disposition position of a spherical joint for coupling exhaust pipes to each other in an exhaust system, and an exhaust system, which enable engine vibrations to be more effectively damped. In the present invention, strain gauges are attached at a plurality of locations in an exhaust system (1), simulated vibrations which simulate engine vibrations are imparted to the upstream-side end of the exhaust system (1), and bending strain is measured at each strain gauge. On the basis of the bending strain measured at each strain gauge, detected is a position at which generated is a bending moment that is equal to or greater than or equal to a torque amount which generates a maximum static friction force between a spherical inner-circumferential surface (26) and a spherical outer-circumferential surface (27) of a spherical joint (2) which come into contact with each other, and the detected position is determined to be the disposition position for the spherical joint (2).
