Title: Device for shaping waveform of light
Inventor: ITO HARUYASU
IPC: G02F1/13
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To provide a device for shaping the waveform of light in which generation of diffracted light by the electrode pattern of a spatial optical modulator is suppressed and the waveform can be efficiently shaped with high accuracy. SOLUTION: In the device, the waveform of light spectrally decomposed and converged to form an image by a grating 1 and concave mirrors 2a to 2d is shaped by using an electric address method reflection type spatial optical modulator consisting of a spatial optical modulator 3a for phase modulation and a spatial optical modulator 3b for intensity modulation. The recesses and projections of the electrode pattern in an electrode layer of the spatial optical modulator are embedded and flattened by forming a dielectric layer. Thereby, the transparent electrode layer and the dielectric layer as a whole act as a flat layer having both flat surfaces, and therefore decrease in the efficiency of waveform shaping and its accuracy caused by generation of diffracted light by the recesses and projections can be suppressed.

Title: Oxide superconducting thin film element
Inventor: NAKAO MASAO
IPC: H01L39/24
Filed: 1992-08-18
Abstract: PURPOSE:To obtain a superconducting thin film element of atom and molecule limit operation, by eliminating a part of oxygen atoms in a desired region or a copper-oxygen coupling surface. CONSTITUTION:An oxide superconducting thin film consists of a superconducting layer 3 composed of a coupling surface of copper atoms and oxygen atoms and block layers 4 sandwiching the layer 3 composed of copper atoms 5 and oxygen atoms 6. When the oxygen atoms 6 come off and oxygen atom vacancies 6e are formed in the atom surface, these are doped and superconductivity characteristics are generated. When the distance W between the specimen surface and the probe pin 51 is kept very small, and a voltage of several volts is applied, a tunnel current flows. While the current is controlled to be constant with a controller 52 and a piezoelectric element 53, the position and the arrangement of each atom are discriminated by scanning using the probe pin 51. Hence by using an electrolytic evaporation, atoms (b) on the specimen side are stripped off, or atoms (c) on the probe pin side are attached to the specimen, so that desired atoms are replaced by other impurity atoms, and a Josephson junction at atomic level can be formed.

Title: Uranium enriching device by laser method
Inventor: ARAKI YOSHIO
IPC: B01D59/34
Filed: 1984-10-19
Abstract: PURPOSE:To make the degree of enrichment of enriched uranium uniform, to prevent the scattering of uranium atoms and to improve the performance by stabilizing the vaporization surface of the raw metallic uranium. CONSTITUTION:A metallic uranium supply hole 4a is provided at the lower part of a crucible 4 to supply continuously raw uranium, and the raw uranium is supplied continuously into the crucible 4. An electron beam 2 generated by a filament 1 is deflected by a deflecting magnetic filed 3, and irradiated on the inside of the crucible 4. Metallic uranium 5 in the crucible 4 is consequently vaporized by the irradiation of the electron beam 2 to form an atomic beam 6. Since the vaporization surface is lowered by the vaporization of metallic uranium, the change of the vaporization surface is detected by a vaporization surface meter 16, and the signal is inputted to a controller 17. An uranium feeder 18 is controlled by the controller 17 so that the vaporization surface may be kept within specified limits. Accordingly, the vaporization surface of the metallic uranium 5 is made constant.

IPC: G11B7/26
Filed: 1986-09-19
Abstract: PURPOSE:To obtain an accurate optical monitor of simple structure by placing a light source and a detecting element outside a vacuum container and leading coaxial fibers from them into the vacuum container. CONSTITUTION:The light source 11 outside the vacuum container uses a light emitting diode or semiconductor laser, etc., and its projection light is guided into the vacuum container through an optical fiber to reach the position right above a transparent substrate 13 for monitoring or optical disk substrate 14 which is set previously. The reflection factor to the light varies as a thin film is formed on the substrate 13 and its reflected light enters an optical fiber for return light (both optical fibers are in coaxial integral structure) and reaches the detecting element 11. Then variation in optical characteristics due to the thin film formation is suppressed efficiently by setting the distance between the tip part of the optical fiber 12 and substrate 13 to <=5cm. Further, an optical disk is structured by laminating films on the substrate 14 and a new substrate 13 is moved to right below the fiber 12 at the time of formation of each layer. Then, the reflection factor is monitored through the fiber 12 at the time of the film formation to monitor optical characteristics and thickness of each layer of the optical disk.

Title: Photographic method using magnetic resonance photographic device
Inventor: ITAGAKI HIROYUKI
IPC: G01R33/48
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a photographic method of oblique section in which the procedure of gradient magnetic field application is simplified. SOLUTION: An oblique section is projected to a projecting surface including either axis of X, Y, Z, and phase encode gradient magnetic field and signal read gradient magnetic field are applied in two directions orthogonal within the projecting surface to photograph the oblique section. (a) shows a section to be photographed and a projecting surface thereof, and (b) shows the sequence of oblique section photographing method. The application of the signal read gradient magnetic field is performed only with one-directional gradient magnetic field. When the signal read gradient magnetic field is applied, the position information is imparted to the direction shown by an axis pr', and the image to be formed is an image in which the photographing section is projected to the pr' plane.  The phase encode gradient magnetic field and slice selection gradient magnetic field are applied in two directions (p-direction and r'- direction) orthogonal within the surface defined by the projecting surface. Thus, the simultaneous application of the phase encode gradient magnetic field and the signal read gradient magnetic field with one-directional gradient magnetic field is dispensed with.
