A laundry apparatus according to the present invention ensures an improved laundry drying efficiency. A synthesizing part superimposes, based on the hierarchical structure, the Fourier images of the base elements in Fourier space, to obtain a Fourier image of the entire graphic. The commanding device 4 stores the received service information, and transmits the service information to an image capture device 1. Subsequently, the second trench is filled with an electrically conductive material and then represents a low-ohmic connection from the substrate surface to the buried structure located below the second trench. Consequently, an apparent emission point of diffracted light L2 may be allowed to coincide with an emission point of the light beam L1.
