摘要:
A number of single crystal domains having crystal orientations different from each other cohere to form one grain, and a number of grains cohere to form a piezoelectric material. When a grain has a size exceeding a certain size, cracks take place in the surface of the grain. Because of generation of the cracks constraining forces from adjacent domains are weak, and a displacement which is substantially the same as a displacement ideal to piezoelectric material can be obtained.

A micro displacement mechanism minutely displaces an object to be driven. The micro displacement mechanism includes a stationary part and an actuator fixed to the stationary part so as to rotatably support the object to be driven. The actuator includes a pair of piezoelectric actuators attached to opposite side surfaces of said object to be driven, respectively. The pair of piezoelectric actuators are arranged at point symmetric positions with respect to a center of gravity of the object to be driven.

An information processing apparatus may include a detecting unit to detect a pointing object in a captured image, and a generation unit to generate pointing information based on detection of the pointing object by the detecting unit. The pointing information may indicate a position of the pointing object determined using a pointable range set based on a user in the captured image. The apparatus may further include a communication unit to transmit the pointing information to an external apparatus.
