Abstract: A notification device basically including a display and a controller. The display is configured to selectively display first information related to a traveling state of a first human-powered vehicle and second information related to a positional relationship between the first human-powered vehicle and a second human-powered vehicle that is different from the first human-powered. The controller is configured to control the display to display the second information in a case where the positional relationship between the first human-powered vehicle and the second human-powered vehicle satisfies a predetermined condition.

Abstract: A notification device basically includes a display and a controller. The display is configured to display information related to positional relationship between a plurality of human-powered vehicles. The controller is configured to set a privilege for displaying the information related to the positional relationship on the display. The controller is further configured to display the information related to the positional relationship on the display in a case where the privilege for displaying information related to the positional relation has been set.

Abstract: There is provided a process for producing a tube member made of fiber-reinforced resin in which it is unnecessary to fold back an end portion of a fiber layer impregnated with uncured resin, and which is capable of joining a tube member, which comprises a resin fiber, and a flanged tube material, which is to be directly rigidly coupled with an engine box or the like, while maintaining the fiber orientation in the initial orientation posture and through an extremely simple process as well. In the process, there is provided a base member 10 comprising a mandrel 1, and an end portion attachment member 2 that is attached to one end thereof and that has a protrusion and a wide diameter portion of a wider diameter as compared to the mandrel. A fiber impregnated with uncured resin is hoop wound around the outer circumference of the mandrel 1 to form a first wound layer 3. A fiber is further helically wound around the outer circumference thereof to form a second wound layer 4.

Abstract: An ATM switching system includes PVC allocation circuits 13-i corresponding to output queues 14-i is disclosed. At the time of arrival of the leading cell of each burst data, if the output line has a room, the PVC of the burst data is stored as information for admission and identification. The subsequently-arriving cells having the same PVC identification information as the stored identification information are “input to an output buffer, and the cells of the remaining burst data are all discarded. Even when a plurality of burst data compete for the same output line, the fact that all the cells other than the first-arriving admitted burst data are discarded prevents the cells from being input other than within a predetermined bandwidth and localizes the burst data affected by the cell discarding due to output queue overflow.
