摘要:
An optical deflection device includes an optical deflection element having a pair of transparent boards arranged in a mutually opposing manner. A liquid crystal layer is filled between the boards and forms a chiral smectic C phase. An orientation film orients liquid crystal molecules in the liquid crystal layer in a substantially perpendicular direction with respect to the liquid crystal layer. Electrodes generate an electric field in a substantially parallel direction with respect to the liquid crystal layer. A first voltage application part applies, to the electrodes, an ac voltage of a deflection frequency switching the optical deflection direction of the optical deflection element. A second voltage application part applies, to the electrodes, an ac voltage of a higher frequency than the deflection frequency. A stop process part causes the second voltage application part to apply the ac voltage of the higher frequency than the deflection frequency after causing the first voltage application part to apply the ac voltage of the deflection frequency, when stopping an operation of switching the optical deflection direction of the optical deflection element.
摘要:
A light deflection element has a pair of transparent substrates 2, 3; a chiral smectic C phase liquid crystal 5 with a homeotropic alignment filled between the pair of transparent substrates 2, 3; and at least an electric field applying device 6 for activating an electric field in the liquid crystal 5. Because a chiral smectic C phase liquid crystal is used, the problems of the conventional light deflection element, such as high cost, light loss, large size, and optical noise etc. due to its complicated structure, can be greatly improved. The conventional low response time due to the smectic A phase or the nematic liquid crystal is improved, thereby the high-speed response is possible.

An optical element, an optical device, and a display device are disclosed that are able to change a polarization state in time order and to produce polarized light with little wavelength dependence and superior in polarization purity, and able to perform pixel shift easily and accurately to realize high resolution image display. The optical element has a translucent surface parallel to the rotational axis of the optical element, and at least a portion of the translucent surface is formed from an optically anisotropic medium. A polarization state of a light beam transmitting through the translucent surface is switched in time order along with rotation of the optical element.

A magneto-optical recording medium includes a recording layer which is composed of A memory layer comprising a ferromagnetic layer with perpendicular anisotropy, and an auxiliary layer comprising antiferromagnetic layer which exhibits an antimagnetic phase at room temperature, and a ferromagnetic phase at temperatures near the Curie temperature of the memory layer which is higher than room temperature, because of the occurrence of magnetic phase transformation, with the memory layer and the auxiliary layer being overlaid. A magneto-optical recording method using this magneto-optical recording medium is described.
摘要:
In a device for recycling a recording medium by removing a film-like image forming substance from the medium, a separating member contacts one side of the medium carrying the substance. The separating member is durable because its surface contacting the medium is provided with a measure against deterioration. Anticorrosion means reduces the deterioration rate of the separating member.
摘要:
A three-dimensional magnetic memory medium which comprises a substrate, a plurality of magnetic layers and a plurality of nonmagnetic layers. The magnetic layers and the nonmagnetic layers are alternately stacked one above the other on the substrate. Each magnetic layer comprises a transfer area, wherein assuming that n is a positive even whole number, the (n-1)th magnetic layer (the 3rd layer, the 5th layer, the 7th layer, . . .) has a transfer pattern different from that of the nth magnetic layer (the 2nd layer, the 4th layer, the 6th layer, . . .). An uppermost magnetic layer is used as a signal writing area and as a signal reading area. A position corresponding to a signal "1" and a position corresponding to a signal "0" are arranged in the signal writing area at a position superposed on a position of "1" and on a position of "0" in a transfer pattern of the (n-1)th magnetic layer, respectively. A guide line is provided in the signal writing area so that a magnetic bubble is movable between the position of a signal "1" and the position of a signal "0" along the guide line.
