This invention pertains to a device and method for making same. The single pin allows the hydraulic cylinder to be supported by an inner transom plate in a manner that allows it to rotate in conformance with movement of a steering arm of a marine propulsion device. When the signal line has a breakage, a cutting means can cut the two ends of the root trace connected to a closed-loop branch through one of the apertures, and a welding means can weld the broken signal line and the isolated closed-loop branch extended from a first common electrode in a lower layer together through one aperture and another. A detectable change is brought about as a result of the hybridization of the oligonucleotides on the nanoparticles to the nucleic acid. This exerciser is more versatile than the prior art. In addition, the conditions suitable for sheet feeding can be satisfied for various sheet materials different in size and thickness by adjusting the distance between the point of contact of the uppermost sheet material with the feeding roller and that of nip formation, such that modulus values are equated to various sheet materials.
