20080205842 | Photonic structure - 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.

20100096263 | Solid surface smoothing apparatus - 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.

20100207041 | Method of Smoothing Solid Surface with Gas Cluster Ion Beam and Solid Surface Smoothing Apparatus - Scratches or similar surface roughness in a solid surface is reduced by gas cluster ion beam irradiation. A method of smoothing a solid surface with a gas cluster ion beam includes an irradiation step in which the solid surface is irradiated with a gas cluster ion beam, and the irradiation step includes a process of causing clusters from a plurality of directions to collide with at least an area (spot) irradiated with the gas cluster ion beam on the solid surface. Collision of the clusters from a plurality of directions with the spot is brought about by an irradiation of the gas cluster ion beam in which flight directions of the clusters diverge with respect to a center of the beam, for example. | 08-19-2010 |
20100230616 | METHOD OF SMOOTHING SOLID SURFACE WITH GAS CLUSTER LON BEAM AND SOLID SURFACE SMOOTHING APPARATUS - Surface roughness having intervals of several tens of nanometers to about a hundred micrometers in a solid surface is reduced by directing a gas cluster ion beam to the surface. An angle formed between the normal to the solid surface and the gas cluster ion beam is referred to as an irradiation angle, and an irradiation angle at which the distance of interaction between the solid and the cluster colliding with the solid dramatically increases is referred to as a critical angle. A solid surface smoothing method includes an irradiation step of directing the gas cluster ion beam onto the solid surface at an irradiation angle not smaller than the critical angle. The critical angle is 70°. | 09-16-2010 |
