Abstract: There is provided a technique capable of evaluating an anisotropy of an object with a large field of view, in a non-destructive manner and with high angular resolution. An object 1 is irradiated with X-rays from a radiation source 22 of a phase-contrast X-ray optical system 2. A change characteristic in X-ray scattering intensities for individual relative angles each formed between an incident angle of the X-rays and an anisotropic structure in the object 1 are then acquired. Evaluation data for evaluating a state of the anisotropic structure in the object 1 is then generated based on the change characteristic in the X-ray scattering intensities.

Abstract: There is provided a technique for non-destructively and relatively easily acquiring orientation information of an anisotropic material even for a large-sized object. An object is irradiated with X-rays in a tangential direction of a curved anisotropic material from a radiation source of a phase-contrast X-ray optical system. A scattering image is then obtained using a detection signal of X-rays having penetrated through the object. Structure information of the anisotropic material is acquired based on the scattering image.

Abstract: An X-ray image generation device includes a moving mechanism that moves an object relative to a grating part in a direction crossing X-rays emitted toward the grating part. The grating part includes N (2?N) regions along the direction of movement by the moving mechanism. A cyclic direction of a grating structure in each of the plurality of gratings belonging to an ith (1?i?N?1) region out of the N regions and a cyclic direction of a grating structure in each of the plurality of gratings belonging to an (i+1)th region out of the N regions are different directions. The plurality of gratings are configured so that moiré interference fringes generated in the N regions have a cyclic intensity fluctuation measurable by the detector and of at least one cycle or more in the direction of movement by the moving mechanism.

Abstract: A raw ceramic portion is formed on each of first and second lateral surfaces of a raw ceramic body. The raw ceramic portions contain ceramic particles and more of at least one constituent selected from Ba, Mg, Mn, and a rare-earth element between the ceramic particles than the ceramic section of the raw ceramic body in terms of total amount. The raw ceramic body is fired with the raw ceramic portions thereon. In this way, a ceramic electronic component is obtained that has a main body left after the raw ceramic body is fired with the raw ceramic portions thereon.

Abstract: In a manufacturing method for a monolithic ceramic electronic component, a plurality of green chips arrayed in row and column directions which are obtained after cutting a mother block are spaced apart from each other and then tumbled, thereby uniformly making the side surface of each of the green chips an open surface. Thereafter, an adhesive is applied to the side surface. Then, by placing a side surface ceramic green sheet on an affixation elastic body, and pressing the side surface of the green chips against the side surface ceramic green sheet, the side surface ceramic green sheet is punched and stuck to the side surface.
