    摘要： A photonic crystal 2 with plasticity is arranged by making microspheres of silica or barium titanate or air bubbles be contained in a gel substance. When an external force is applied to this photonic crystal, photonic crystal 2 deforms and the photonic band gap is readily changed thereby. When the photonic band gap changes, the passage of light of a specific wavelength is restricted. Light of a desired wavelength is thus output from photonic crystal 2. With this invention, this wavelength can be varied readily by means of an external force.

    摘要： To provide a tool changer of a machine tool that makes it possible to surely execute machining as designated in a machining program without any need for the editing of the machining program or the replacement of tools and without complicating the device structure. The tool changer 11 includes a tool correspondence table A showing a correspondence relation between a program-designated tool T0001 designated in a machining program O0001 and an actual use tool T0003 actually used according to the machining contents designated in the machining program, wherein the actual use tool corresponding to the program-designated tool is found by using the tool correspondence table A and the found actual use tool is decided as a subsequent process tool.

    摘要： An image reconstructing apparatus wherein the object under examination is irradiated in at least one direction to provide projection data, and the provided projection data is optically processed to form a reconstructed image representing the internal information of the object. An image associated with the projection data is formed and stored in the storage medium. The stored image is optically read out of the storage medium. The read out stored image which corresponds to one direction of irradiation is integrated at a time to produce sum data. The sum data and projection data corresponding to the same direction of irradiation are compared to form correction data. An image associated with the correction data is formed and optically superposed on the stored image in the storage medium corresponding to the same direction of irradiation, to produce the reconstructed image.

    摘要： An apparatus for optically measuring a three-dimensional surface shape and inner structure of a three-dimensional object without destruction of the object. When a light pulse having a short pulse width is applied to the object, there are observed a flux of light pulses reflected from or transmitted through the object which has information on the three-dimensional surface shape and inner structure of the object. This apparatus optically measures and analyzes in the order of a picosecond the intensity distribution of the light pulses from the object with time and space, to thereby obtain a complete three-dimensional image of the object.
