    摘要： To provide a driver for driving piezoelectric actuators with drastically reduced drive currents during on/off switch control, thereby reducing the power consumption of an overall device. Each of the plural piezoelectric actuators 1a to 1h is composed of a plate and piezoelectric sheets attached to the opposed surfaces of the plate. A positive feeder line 19 or a negative feeder line 21 is connected to the opposite side of each piezoelectric sheet to the side attached to the plate. The controller 27 on-controls the piezoelectric sheets of each of the piezoelectric actuators 1a to 1h by selectively applying a positive or negative drive voltage thereto. Thereafter, the controller 27 turns off the drive voltage applied to the piezoelectric sheets subjected to on-control and simultaneously with this, turns on a drive voltage to the piezoelectric sheets of any other one the piezoelectric electric actuators 1a to 1h to be driven next.

    摘要： A method for forming a glass optical element by press forming a thermally softened glass material with a preheated forming mold composed of an upper and a lower die. The glass material, the upper die and the lower die are heated within respectively prescribed temperature ranges, the preheating temperature of the upper die being below the preheating temperature of the lower die. The thermally softened glass material is pressed in the preheated forming mold, and the forming surfaces of the upper and the lower dies are cooled simultaneously with the start of the initial pressing, during the process of the initial pressing, or after the completion of the initial pressing.
