Abstract: A variable posture bed includes a base rest located on a floor surface; a bed board arranged in a horizontal state above and opposite the base rest; a connection support portion disposed at the center of the base rest between the base rest and the bed board and that supports the bed board to be vertically movable in all directions around the center thereof; connection support portions disposed at four corners of the base rest and the bed board and that support the bed board to be vertically movable; and a drive control device that continuously moves the bed board in the vertical direction with a predetermined operation pattern and that limits the vertical movement of the head side of the bed board between the horizontal position and a predetermined upper position.

Abstract: The capacitor related to the present invention has a lower electrode, a dielectric film provided on the lower electrode and made mainly of crystal containing at Ti, O and at least one element selected from the group consisting of Ba and Sr, and an upper electrode provided on the dielectric film, wherein the dielectric film includes a layer which contacts the upper electrode. In case the dielectric film which has a thickness of at least 5 nm and exhibits a first-order differential spectrum measured by means of Auger electron spectroscopy, and the in the first-order differential spectrum, a ratio A/B is at most 0.3, where A is the absolute value A of a difference between a third peak appearing near 420 eV and a fourth peak appearing at a higher energy level and near the third peak, and B is the absolute value B of a difference between a first peak appearing near 410 eV and a third peak appearing at a lower energy level and near the first level.
