Abstract: An impeller and a rotary machine include an inner diameter portion, a disk portion, a blade portion, and a cover portion. The disk portion includes a main body portion adjacent to the blade portion, and a fixing portion disposed at a radially inward side of the main body portion and fitted at a radially outward side of an outer peripheral surface of the inner diameter portion. The fixing portion is formed so as to protrude from the main body portion toward another side in an axial direction.

Abstract: In an inverter in which noise reducing coils and a smoothing capacitor are provided on a power line to an inverter module to achieve a no-busbar configuration, simplification of the manufacturing process, reduction of the influence on the size of the inverter, enhanced noise reducing function, reduction in cost and so on, the smoothing capacitor is electrically connected, on the inverter module, to the power line in parallel with a power system board, and the noise reducing coils are connected to the power line by directly connecting output lead wires thereof to P-N terminals of the inverter module.

Abstract: The present invention provides a leaf seal device which is available to assemble easily and to control and to set an inclination angle and a space of a sealing section. In the leaf seal device of the present invention, a connection holding section 21 of a sealing plate 12 is bent at a first bending section 22. Thereby, since laminated a plurality of sealing plates 12 are engaged sequentially at the first bending section 22, a radial direction is defined so as to become easily assemble. Also, according to inclining a face 24 at an inner circumferential side of the connection holding section 21, a pitch and a space of a sealing section 31 are changed. Therefore, the space of the sealing section can be controlled, if controlling a bend angle of the first bending section 22.

Abstract: An object is to improve safety. Provided is a power storage system including a battery apparatus 1; a power converter 2 provided between the battery apparatus 1 and a load 3 and that can control power supplied from the battery apparatus 1 to the load 3; and a battery monitoring circuit 4 that detects an abnormality in the battery apparatus 1. When an abnormality in the battery apparatus 1 is detected by the battery monitoring circuit 4, the power converter 2 supplies power stored in the battery apparatus 1 to the load 3 or to an internally provided internal load at or below a current value or power value that is set in advance, or alternatively, at a current value or power value that the load 3 demands, within a range that does not exceed an upper limit that is set in advance.

Abstract: A method for separating oil from water, wherein, in order to simplify the treatment processes, to improve separation efficiency, and to make possible the recycling of added solvents, in the course of separation treatment of oil from waste water containing fats and oils, paraffinic hydrocarbons of low specific gravities, as extractive solvents for fats and oils, and inorganic or organic coagulants are added to the waste water; the mixture is then stirred and allowed to stand; the oil-containing scum separating as an upper layer is then removed so as to separate the oil from water, and furthermore, the solvent previously added is recovered from the oil-containing scum so removed by means of distillation.
