In one embodiment, a circuit is provided. The user is presented with a hierarchy of queries based on wallet-type and non-wallet type information designed to ensure the identity of the user and prevent fraud, false negatives and other undesirable results. On the basis of the rotation speed detected by the frequency generation pattern, a combination of a PLL circuit and a driving transistor drives the motor at the high and the low rotation speeds on the high and the low rotation speed modes, respectively. An end of the drainage passage and an end of the gas discharge passage on the side of the other end holding member are joined to each other. The actual position of the instrument arm is detected. Under conditions specified, the dielectric layer forms to have a first thickness over the closely spaced regions and a second thickness over the widely spaced regions.
