摘要： A pyroelectric IR sensor equipped with a chopper for opening and closing a shielding plate so that infrared rays emitted from an object are allowed to be incident onto a pyroelectric sensor unit and intercepted therefrom, and having a structure capable of providing a large shielding width for the shielding plate without enlarging the chopper. Piezoelectric members are formed on a thin elastic sheet composed of a planar sheet having a tip to which a shielding plate is attached, except for a partial region which functions to magnify oscillations for enlarging displacement of the shielding plate.

摘要： Rectangular piezoelectric substrates each of which has main surfaces opposed to each other, measures 50 .mu.m thick by 1 mm wide by 8 mm long, and is made of lithium niobate (LiNbO.sub.3), are directly bonded on the main surfaces so that their axes of polarization are set in directions reverse to each other, thereby composing a piezoelectric element. Electrodes which are 0.2 .mu.m thick and made of chromium-nickel are formed on the two main surfaces of the piezoelectric element opposed to each other, thereby resulting in a precision displacement control actuator of a bimorph type mechanical-electrical converter element. This configuration makes it possible to provide a compact precision displacement control actuator which has a large displacement and extremely small variations of characteristics such as displacement and resonance frequency.
