The present invention provides a long-range surface plasmon optical waveguide sensor which has a reduced loss of an electromagnetic wave, an increased sensitivity and limitation of detection and a high analysis speed, and enables fabrication of a sensor of various sizes such as a small-sized or lightweight system, etc. This film provided with a hardcoat comprises: a transparent substrate film; and, stacked on the transparent substrate film in the following order, a hardcoat and a slip layer. The alloy improves adhesion to the SiO2, avoids agglomeration of the Ag, reduces or eliminates diffusion at the SiO2 surface, reduces electromigration and presents a passive exterior surface. Adjacent islands are connected by bridging portions in the form of serpentine members. The playback queuing mechanism can build the latency. The motorcycle carriage 14 is comprised of an open carriage mounted to a frame having wheels thereunder with the frame extending to a coupling member mountable to a motorcycle receiver.
