Abstract: According to one embodiment, an X-ray diagnosis apparatus includes a table, an imaging unit, and processing circuitry. The table includes a table top on which a subject is placed. The imaging unit includes an X-ray tube which emits X-rays to the subject and an X-ray detector which detects the X-rays. The processing circuitry detects contact between an object and at least one of the imaging unit and the table. The processing circuitry executes control to display contact position information relating to a position in contact with the object based on a detection result.

Abstract: This invention relates to an electronic element having an electron function which acts even at room temperature using a super dielectric effect. The element has a crystalline electron system, and uses a perovskite crystal in the ground state of a “macroscopic quantum effect” which occurs when the electron number is defined, or nearly defined. The electronic element used in an electric field such that the two-dimensional plane of doped crystals ground state of a “fractional quantum Hall effect” wherein the doping amount of the crystals is 0.05 or less, or if localization is introduced, 0.6 or less, and the crystals may have a doping amount variation determined by the degree of localization.
