A new method and structure is provided to connect a planar, spiral inductor to underlying interconnect metal, the interconnect metal has been created over a semiconductor surface. If the multiple-format recording mode is set, and if a recording size is set to one of the recording formats, the recording size set by the recording-size setting section is set to all the recording formats recorded in one-time image capturing. The double walled construction of the flanges stiffens the ends significantly reducing the risk of deformation by the hydrostatic forces produced by wet concrete during installation. Next, a voice signal is received. A receive clock signal is generated such that it is synchronous in frequency with analog sampling clock signals and has a particular phase offset with respect to one of the sampling clock signals.
