A RAMOsubstrate includes a single crystal represented by a formula of RAMO(in the formula, R indicates one or a plurality of trivalent elements selected from a group consisting of Sc, In, Y, and a lanthanoid element, A indicates one or a plurality of trivalent elements selected from a group consisting of Fe(III), Ga, and Al, and M indicates one or a plurality of bivalent elements selected from a group consisting of Mg, Mn, Fe(II), Co, Cu, Zn, and Cd). An epitaxially-grown surface is provided on one surface of the RAMOsubstrate, a satin-finish surface is provided on another surface. The satin-finish surface has surface roughness which is larger than that of the epitaxially-grown surface.

A processing apparatus includes a rotary table that causes a workpiece to rotate around a rotary axis, a roller-shaped member that rotates on an axis orthogonal to the rotary axis of the rotary table, a vertical driving section that is driven in a direction of the rotary axis of the rotary table so as to bring the roller-shaped member and the workpiece into contact with each other, an ultraviolet ray irradiation source that irradiates a portion between the roller-shaped member and the workpiece with an ultraviolet ray, a polishing material that is supplied to the portion between the roller-shaped member and the workpiece, and a light scattering medium that is supplied to the portion between the roller-shaped member and the workpiece and scatters an ultraviolet ray from the ultraviolet ray irradiation source.

Processing apparatus and processing method

To provide a structural color body that exhibits color using physical phenomena such as reflection, interference, diffraction, and scattering of light, and in which the decorative effect can be further enhanced, the present invention configures a structural color body by combining a plurality of structural color portions that structurally exhibit different colors from each other.

Structural color body

A cutting device is provided which can simultaneously achieve a shorter machining time, lower machining resistance during cutting, and high-precision machining. To be specific, the cutting device of the present invention includes a three-axis tool unit including a first actuator operating in a u direction, a second actuator operating in a v direction orthogonal to the u direction, a third actuator operating in a w direction orthogonal to the u direction and the v direction, a tool holder disposed at the intersection of the u direction, the v direction, and the w direction, a tool mounted in the tool holder, and three sensors for measuring the displacements of the first, second, and third actuators, respectively and feeding back displacement signals representing the measured displacements, wherein the first, second, and third actuators of the three-axis tool unit vibrate so as to perform vibration cutting on a work material.

Cutting device, machining method, and die machined by the machining method
