Abstract:
1. A logical element comprising an oscillation portion which mechanically oscillates; excitation means for parametrically oscillating said oscillation portion in either of a first oscillation state and second oscillation state different in phase by π; an input portion which receives a signal for parametric oscillation input into said excitation means; and an output portion which outputs a signal corresponding to either of the first oscillation state and second oscillation state of said oscillation portion that parametrically oscillates, wherein binary information of “0” or “1” is expressed using the first oscillation state or second oscillation state, wherein said oscillation portion includes a beam having a piezoelectric layer formed from a piezoelectric material, said excitation means is the piezoelectric layer, said input portion is an input electrode which receives an AC voltage for parametrically oscillating the beam, and said output portion is an output electrode for outputting a signal based on a piezoelectric effect of the piezoelectric material.
