DRIVE CIRCUIT FOR CONTROLLING MOVABLE VIDEO HEAD |
摘要 |
Improved deflection of a bimorph having a pair of electrically poled piezo-ceramic elements bonded to opposite sides of a common substrate is achieved by applying to each element a deflection voltage whose polarity is always in the poling direction of the element to which it is applied. By maintaining the polarity of the deflection voltages in the poling direction of the piezo-ceramic elements, large amplitude deflection voltages can be used without de-polarizing the piezo-ceramic elements. |
