The present invention separates, absolutely, the functions of camouflage and jamming. In an embodiment, the basis functions may be used to refine an area of interest in the signal in frequency or in time, and the continuous wavelet transform may be used to identify a maxima ridge in the scalogram at scales with characteristic frequencies proximal to the frequency or frequencies of interest. Once the hardness component concentration of the treatment water sampled by sampling pipe 21 reaches a specified concentration, the watercourse selection of valves 2 and 6 and valves 9 and 13 are switched, causing raw water to flow through second water softener 11. Then, half-dicing is performed from the upper surface side of the sealing resin 5a on the basis of the target marks for dicing to form grooves whose bottoms reach the wiring substrate. Each end flange may have a second circular rib intermediate the first circular rib and the peripheral rim and joined thereto by the plurality of equispaced spokes.
