摘要： To enable fabrication of a precise stamped product having an extremely low surface roughness. Ripples 24 having depths ranging from 10 to 100 nm are formed with periodicities ranging from 100 to 1000 nm on a stamping tool surface that comes into contact with a workpiece material. The ripples 24 have a stripe shape extending in a direction substantially perpendicular to the direction of sliding between the stamping tool (die 21) and the workpiece material (the direction of the arrow a). The ripples 24 serve as micro pools. For example, a product that is required to have a surface roughness of the order of several tens of nm or lower can be satisfactorily stamped.

摘要： In a method of irradiating a gas cluster ion beam on a solid surface and smoothing the solid surface, the angle formed between the solid surface and the gas cluster ion beam is chosen to be between 1° and an angle less than 30°. In case the solid surface is relatively rough, the processing efficiency is raised by first irradiating a beam at an irradiation angle θ chosen to be something like 90° as a first step, and subsequently at an irradiation angle θ chosen to be 1° to less than 30° as a second step. Alternatively, the set of the aforementioned first step and second step is repeated several times.

摘要： A photonic structure has rods arranged with periodicity which is of a non-translational symmetry and defined in a polar coordinate system, which uses a distance in a radial direction and an angle in a circumferential direction, and has a center of the polar coordinate system used as a reference. A heterointerface is provided between adjoining areas of the plurality of areas. The positions of the centers of the polar coordinate systems of the plurality of areas are different. Lines of rods are smoothly connected between adjoining areas of the plurality of areas at the heterointerfaces. Rods are removed in a spiral shape or in a curve whose radius of curvature changes, to form an optical waveguide in the spiral shape or in the curve.

摘要： The invention provides a tunable filter that can minimize adjacent channel cross talk despite an increase of a number of available wavelengths and quickly switch a wavelength to be used, and manufacturing method thereof, and also an optical switching device comprising such tunable filter. In a tunable filter having a Fabry-Perot etalon structure, not less than two cavity gaps 114 to 116 are provided and separation between the cavity gaps is controlled by any of electrostatic drive, electromagnetic drive or piezoelectric drive. In this case, the cavity gaps can be formed through the steps of forming a sacrificial layer in advance where a cavity gap is to be formed; forming a plurality of optical multilayer films 100 to 103; and removing the sacrificial layer by etching. Substrates 107 and 109 are combined through a supporting column 108.

摘要： A cubic element of photonic crystal is integrally formed on the surface of a photo-detection element, and a portion of the photonic crystal cubic element is irradiated with ultraviolet rays thereby to change the refractive index of the portion of the cubic element that has been irradiated with ultraviolet rays. Alternatively, by causing globular particles having different refractive indices to eject on the surface of the photo-detection element from an ink-jet apparatus having a nozzle provided with a temperature control part by controlling temperature of the nozzle to form a laminate of globular particle layers having different refractive indices, a photonic crystal lens is integrally formed on the surface of the photo-detection element.

摘要： The density of the magnetic head protective layer is set to be higher than the density of a magnetic disc medium protective layer. Also, the Young's modulus of the magnetic head protective layer is set to be higher than the Young's modulus of the magnetic disc medium protective layer. Furthermore, the thickness of the magnetic disc medium protective layer is set to be between 1 and 10 nm, and the hardness of the magnetic head protective layer is set to be between 1.5 and 2.0 times the hardness of the magnetic disc medium protective layer. It is thus possible to provide a highly reliable magnetic disc apparatus.

摘要： A ferroelectric thin film (6) is formed on the surface of a support spring (4) for pressing a magnetic head (3) against a magnetic disc (1) so that the magnetic head (3) is in close contact with the magnetic disc (1). When the magnetic head (3) jumps out of the magnetic disc (1), electrostatic attractive force acts between the ferroelectric thin film (6) and the magnetic disc (1) to prevent the jumping of the magnetic head (3). Further, when the magnetic head (3) is excessively pressed against the magnetic disc (1), electrostatic repulsive force acts between the ferroelectric thin film (6) and the magnetic disc (1) to prevent the pressing force from increasing, thereby preventing the magnetic head (3) and the magnetic recording surface of the magnetic disc (1) from being worn or scratched.

摘要： A new method for determining an attitude of a sensor with respect to a moving body is proposed. A movement vector is measured by a sensor mounted in the moving body. In addition, the attitude of the sensor with respect to the moving body is determined using the movement vector measured by the sensor when the moving body starts to move.

摘要： The average roughness Ra of a mold tool surface that comes into contact with a material to be molded measured for a measurement area 10 μm square or smaller is equal to or lower than 5 nm, and fine granular projection structures having diameters ranging from 10 to 80 nm and heights ranging from 10 to 40 nm are formed on the mold tool surface with a density of 400/μm2 or higher. The frictional force due to the anchoring effect or the digging effect is reduced, and the adhesive force due to meniscus is also reduced. The release resistance is significantly reduced without affecting the dimensional precision of a fine molded product.
