Abstract:
An X-ray imaging apparatus acquiring a differential phase contrast image of a test object without using a light-shielding mask for X-ray. The apparatus includes an X-ray source, a splitting element configured to spatially divide an X-ray emitted from an X-ray source and a scintillator configured to emit light when a divided X-ray beam divided at the splitting element is incident on the scintillator. The apparatus also includes a light-transmission limiting unit configured to limit transmitting amount of the light emitted from the scintillator and a plurality of light detectors each configured to detect the amount of light that has transmitted through the light-transmission limiting unit. The light-transmission limiting unit is configured such that a light intensity detected at each of the light detectors changes in response to a change in an incident position of the X-ray beam.
Abstract:
Glass used in a flat panel display (15) can be recycled in line with conservation of the global environment by separating the lead component in the glass. A method for disassembling a flat panel display having a structure in which a face plate (2) mainly made of glass and a rear plate (1) are air-tightly joined to each other with frit glass (5) through a frame (3) is characterized by comprising the step of separating the face plate (2) and the rear plate (1). The separating step is characterized in that the separation is carried out by cutting, melting, or fusing.

Abstract:
A method of producing a material capable of electrochemically storing and releasing a large amount of lithium ions is provided. The material is used as an electrode material for a negative electrode, and includes silicon or tin primary particles composed of crystal particles each having a specific diameter and an amorphous surface layer formed of at least a metal oxide, having a specific thickness. Gibbs free energy when the metal oxide is produced by oxidation of a metal is smaller than Gibbs free energy when silicon or tin is oxidized, and the metal oxide has higher thermodynamic stability than silicon oxide or tin oxide. The method of producing the electrode material includes reacting silicon or tin with a metal oxide, reacting a silicon oxide or a tin oxide with a metal, or reacting a silicon compound or a tin compound with a metal compound to react with each other.
Abstract:
An electron-emitting device having an electron-emitting portion between electrodes on a substrate comprises a region A and a region B, the region A being electrically connected through the region B to at least one of the electrodes, electric conductivity s of the material mainly constituting the region A and electric conductivity of the material s mainly constituting the region B being in the relation of s > s , and the region A being the electron-emitting portion. An electron beam-generating apparatus and image-forming apparatus comprise the electron-emitting device and a modulation means for modulating the electron beams emitted from the electron-emitting elements in accordance with information signals.
