摘要： An actuator has a driving first coil and a driving second coil. A capacitor is electrically connected to both the first coil and the second coil through a discharge switch using electric power accumulated in a capacitor which can be selectively supplied. An operation portion for operating the discharge switch is electrically connected to the discharge switch. For example, when an electric power supplied to the operation portion is cut due to a power failure, the second coil and the capacitor are electrically connected to each other through the discharge switch.

摘要： An actuator used in a safety stop device for an elevator has: a movable portion displaceable between an actuation position where the safety stop device for the elevator is actuated and a normal position where the actuation of the safety stop device is released; and an electromagnetic coil for displacing the movable portion when a current flows through the electromagnetic coil. A device for inspecting operation of the actuator has a feeder circuit for supplying an amount of electricity required for a semi-operation which is less than that required for a full operation for displacing the movable portion from the normal position and the actuation position to the electromagnetic coil.

摘要： Magnetic tunnel junctions (MTJs) in magnetic random access memory (MRAM) are subject to read disturb events when the current passing through the MTJ causes a spontaneous switching of the MTJ due to spin transfer torque (STT) from a parallel state to an anti-parallel state or from an anti-parallel state to a parallel state. Because the state of the MTJ corresponds to stored data, a read disturb event may cause data loss in MRAM devices. Read disturb events may be reduced by controlling the direction of current flow through the MTJ. For example, the current direction through a reference MTJ may be selected based on the state of the reference MTJ. In another example, the current direction through a data or reference MTJ may be alternated such that the MTJ is only subject to read disturb events during approximately half the read operations on the MTJ.

摘要： A switchgear apparatus is provided in which an impact induced by a close operation is mitigated, featuring space saving and high reliability with low costs.The switchgear apparatus includes a switching unit 3 that is composed of a fixed electrode 1 and a movable electrode 2; a movable shaft 4 that is extended from the movable electrode 2; an operating mechanism 5 that produces driving force and transfers the driving force to the movable shaft 4; a switching-unit holder 6 that holds the switching unit 3 and the movable shaft 4 thereinside; and a holder supporting unit 7 that has a fixing plane so as to fix the switching-unit holder 6 thereonto. The switchgear apparatus is arranged in such a manner that the holder supporting unit 7 serving as the fixing plane is constituted of a plurality of plates layered in the axial direction along the movable shaft 4. In a case of the close operation, because kinetic energy in the overall system is consumed by the friction generated between the layered plates owing to distortion of the layered plates, energy that allows the movable electrode 2 to bounce back and forth is lowered, so that it is possible to shorten a chattering time.
