Support members for a reciprocating piston internal combustion engine are disclosed. A control platform is adapted to generate a predetermined time period, wherein the predetermined time period is reset when an acknowledgement signal is received. Alternatively a plurality of collar segments having a circular wall within can form the pipe integrally with the collar. The display control unit 54 performs control to sequentially display image data combined by the image composition unit 52 while the image data of the frames are captured by the image capturing unit 16 at predetermined time intervals. A limiting device is located on the top panel and engaged with the mounting member to prevent the mounting member from sliding relative the top panel. The structural body can generate localized plasmon resonance having a sufficiently large intensity and be produced at low cost through a simple production process, and having a large surface area.
