Abstract
In a logical element, supporting portions, and a beam supported by them at two ends are formed. The beam has a back side surface spaced apart from the top side surface of a substrate, creating a space between the facing surfaces of the beam and substrate. An excitation electrode is formed on one supporting portion, whereas an oscillation detecting electrode is formed on the other supporting portion.
Claims14
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.
