In a full-adder of complementary carry logic voltage compensation, two input terminals of a first multiplexer are connected to a carry input and a carry inverted phase input respectively; an add signal is connected to a select signal; an input terminal of a first inverter is connected to an output signal of the first multiplexer. A first light beam is incident on a diffraction grating from the side thereof facing the inside of the device, and a second light beam is incident on the diffraction grating from the side thereof facing air. A definition of a condition for completion of the delayed instant copy operation is received, and the delayed instant copy operation is completed upon the condition being met. An adhesive fastens the mounting bracket engaging member to the mounting bracket. A pumping mechanism is provided on the tool body, the pumping mechanism including first and second gerotors. A channel profile is determined from the filtered impulse responses.
