Abstract: A motorized table apparatus comprises: a support unit for supporting a movement table so as to allow it to move in a single axis direction relative to a stationary unit which is fixed to the movement table; a slide member which is equipped on the movement table and which has a length equivalent to, or more than, a moving range of the movement table; an ultrasonic oscillators which is equipped on the stationary unit, which moves the movement table, and which comprises a single piezoelectric body and two drive elements; and a pressure application unit for supporting so that the two drive elements of the ultrasonic oscillator and the slide member are pressed by a constant force, wherein a plurality of the ultrasonic oscillators are equipped.

Abstract: A multilayered piezoelectric element in which first internal electrodes include first exposed portions formed at the end portion of a first piezoelectric material. And the second internal electrodes include second exposed portions formed at the end portion of a second piezoelectric material.

Abstract: A liquid crystal lens comprises a biconcave lens and a pair of transparent flat plates arranged before and behind the lens. The biconcave lens has a pair of concave principal surfaces covered with transparent electrodes, a flat portion on its outer periphery, and an electrode extending across the flat portion and connecting the transparent electrodes. Each of the transparent flat plates has a flat principal surface covered with a transparent electrode, the surface facing the concave principal surface, a flat portion on its outer periphery, and an electrode extending across the flat portion and connected to the transparent electrode. The biconcave lens and the pair of transparent flat plates are cemented to one another in a spaced manner by sealants with their respective flat portions flush with one another. Liquid crystals are stored individually in spaces defined between the lens and the flat plates.
