A mask for forming active regions is formed on a surface portion of a Si layer serving as a semiconductor region with a thermal oxide film interposed therebetween. The surgical fasteners are simultaneously deformable upon activation of the actuator such that a distal end of each surgical fastener secures each end of each luminal structure to complete the end-to-end anastomosis wherein the resulting eversion is exterior to the luminal structures. A state information obtaining unit repeatedly obtains state information representing a state of an own vehicle at the current time. The distal ends of the inwardly extending projections are welded to the outer surface of the stabilizer bar to secure the support ring onto the stabilizer bar. After said processing is performed, a result of said processing is back-annotated to the netlist.
