Abstract: A method of controlling the domain of a nonlinear ferroelectric optics substrate to form an inverted-domain structure in one major surface of a single-domain nonlinear ferroelectric optics substrate. A first electrode (11) is formed in a first major surface of a nonlinear ferroelectric optics substrate (1) in a pattern corresponding to a desired pattern of an inverted-domain structure to be formed, a second electrode (12) is formed on a second major surface opposite the first major surface in a pattern corresponding to that of the first electrode or in a solid film, a dc voltage or a pulse voltage is applied across the first and second electrodes to form local, inverted domains in the desired pattern in the first major surface of the nonlinear ferroelectric optics substrate. An insulating film may be formed between the first electrode and the first major surface to avoid damaging crystals of the nonlinear ferroelectric optics substrate by the current that flow across the nonlinear ferroelectric optics substrate when the dc voltage or the pulse voltage is applied across the first and second electrodes.

Abstract: A plurality of first electrodes are disposed on one of opposite surfaces of a nonlinear optical material substrate which is divided into single domains. Each of the first electrodes is made of an electric conductor having a width which is equal to or smaller than half the width of a designed local inverted-polarization domain. A second electrode is positioned on the other of the opposite surfaces in confronting relation to the first electrodes. A voltage is applied between the first and second electrodes thereby to produce local inverted-polarization domains in the nonlinear optical material substrate.

Abstract: PROBLEM TO BE SOLVED: To provide an emitter apparatus that can control multiple active shutter glasses using different protocols for controlling right and left shutters.SOLUTION: An emitter apparatus 10 sends command signals per protocol by time division multiplex so that intermittent time of each command signal per protocol may not exceed self-running time thereof. More specifically, the emitter apparatus consecutively and alternatively switches and sends a series of first command signals and a series of second signals per N flame, where N is a minimum flame number necessary for glasses to calculate its shutter switching cycle, for example N=2.

Abstract: PROBLEM TO BE SOLVED: To improve the response speed and deformation accuracy of a deformable mirror device having a moving magnet type drive unit. SOLUTION: In deforming a flexible member having a mirror face, a driving force generated by a driving force generating unit is transmitted by a driving force transmission unit and is applied to the flexible member, and the distal end of the driving force transmission unit is made to abut on the flexible member side without fixing. The mass of a movable side as a movable side in deforming the mirror face can be made significantly smaller than the conventional case, and the value of the eigen-frequency of a movable side can be made larger. The driving force transmission unit is disposed by inserting a columnar unit having a spherical distal end into a guide hole in a case. Thus, a longitudinal (perpendicularly to the surface of the case) pressing force can be accurately applied to a pressing reference point of the flexible member by the distal end, and the deformation accuracy of the mirror face can be improved.
