Abstract: A can body manufacturing method has a barrel section of the can body held between first and second rotation bodies. The first body has at a first recess in its outer surface, and the second body has a second projection on its outer surface. The bodies are brought together so the barrel section is pressed radially inward by the second projection and fits into the first recess. When the holding of the barrel section by the rotation bodies is released, that portion of the barrel section corresponding to the first recess and the second projection is caused to restore elastically radially outward. As a result, the outer surface of that portion of the barrel corresponding to the projection and recess is caused to position more outside than the rest of the outer surface of the barrel section.

Abstract: In a constant current circuit, a constant current is caused to flow through a resistor, thereby causing a constant voltage to occur across the resistor. This constant voltage is then superimposed on an output signal of an operational amplifier that is to be fed back to the drain of a field effect transistor, thereby maintaining the same potential in an AC manner between the output terminal of the operational amplifier and the drain of the field effect transistor. In this way, the gate and drain of the field effect transistor is caused to exhibit the same potential in an AC manner, so that no current will occur through the stray capacitance between the gate and drain of the field effect transistor. As a result, similarly to a case of using a feedback capacitor, the input impedance of the field effect transistor can be raised.
