Methods and devices are disclosed for treating the vertebral column. The instruction and sensing point are stored in a second storage region. When the update process is authorized, the system designates the update process as trusted process, allows the update process to download on the computer an update object, and designates the update object as a trusted object. The substrate replacement group has a stack of three cleaningdrying processing units. A regenerator device operates according to each of the parameter sets as modulated to regenerate each of the sinusoidal wave components so that at least one of the frequency and the amplitude of each sinusoidal wave component as regenerated varies from original one, and mixes the regenerated sinusoidal wave components altogether to synthesize the output voice signal. An electrical double layer capacitor has a capacity to feed stable power to an internal circuit in which power consumption increases or decreases in a burst manner and is charged by application of an output of the power source circuit and stores the power.
