A conversion system converts an input signal from a digital signal to an analog signal over an extended dynamic range. First, a substrate having thereon at least a semiconductor layer and a pad layer is provided. The chamber has a gas permeable barrier, constituted by a plug and wadding, which partially encloses the treatment region. The summation circuitry is coupled to the detection circuitry and configured to receive the estimated echo return from the filtration circuitry, receive a tone transmission and echo return from the interface circuitry, subtract the estimated echo return from the tone transmission to generate a substantially pure tone, and provide the substantially pure tone to the detection circuitry. The present invention relates to an adhesive substance, which contains a gas-generating agent for generating gas by giving stimulation via an ultrasonic wave andor impact thereto, generated gas being discharged to the outside of the adhesive substance and discharged gas peeling part of an adhesive surface off an adherend. A frame synchronization correction value is calculated based on the difference between the first significant path position and a constant called frame offset.
