Abstract: An electrostriction actuator comprises upper and lower electrostriction boards, having electrodes individually on either side thereof, and a conductive shim interposed between the inside electrodes. The actuator has a fixed end at one end thereof and a free end for bending movement at the other end. An amplifier for supplying driving voltage to the actuator is an inverted amplifier, whose output terminal is connected to the shim, so that an output voltage is supplied to the inside electrodes. The outside electrode of the upper electrostriction board is connected to a power source (not shown) for supplying constant voltage to the amplifier, and the outside electrode of the lower electrostriction board is connected to a power source (not shown) for supplying constant voltage to the amplifier.

Abstract: The invention is concerned with the miniaturization of construction of solid state imaging devices used in electric cameras, endoscopes or the like. A flexible printed circuit board assembled with some peripheral components thereon is attached to a side surface of a solid state imaging element to expose the element directly to incident light. The element is composed of a CCD chip and a light transparent cover sized about same as the CCD chip, and both are electrically connected using conduction bumps.

Abstract: A swing-driven solid-state imaging device is disclosed which has a CCD image sensor for receiving incident image light and producing an electrical image signal, a stacking piezoelectric element serving as an actuator for vibrating the image sensor on a plane substantially perpendicular to the image light to thereby cause the image sensor to periodically shift to different sampling positions at different points of time in one frame period in an image sensing mode, and a package structure for receiving the image sensor and piezoelectric element. This package structure includes a base plate and a socket plate, spaced apart from and facing each other, and two arrays of flexible conductive support leads which serve as a suspension mechanism for elastically supporting the socket plate above the base plate and also serve as a part of electrical signal transmission wires for the image sensor and piezoelectric element. The image sensor is adapted to be mounted on the socket plate.
