An eddy current probe testing apparatus structured to operate concurrently in a driver pick-up mode and said impedance mode is provided. A manufacturing method of a multilayer substrate for laminating, via an insulating film, a wiring layer formed by patterning a conductive film comprises providing a positioning hole in a conductive film laminated at the beginning and patterning a second andor any subsequent wiring layers after identifying a position of an identification section. At least a part of the rotor vanes have a rear side which is convex on the suction-side and concave on the delivery side. In different positions, different springs can produce different spring force, a corresponding relationship is thus established between the force and the position, and the amount of the gear selecting positions is increasing with the amount of the springs increased, thus the automatic gear shift can be achieved in a transmission having more than six gears. The array of pads is subdivided into N groups of pads respectively numbered Gx, each group containing Px pads. The first deflector member at least partially forms a load path from the bumper to the frame rail under a sufficient offset load applied to the bumper.
