    摘要: The computing device comprises non-recursive, digital filters, with finite impulse response, computing, from samples taken over a period of the power system, for at least two distinct phases, two components with a phase difference of 90.degree. between them and representative of the quantity involved in the phase involved. A matrix computation using a two-dimensional rotation matrix enables the components with a 90.degree. phase difference of the inverse component to be deduced therefrom.

    摘要: In an installation for handling assemblies between the main vessel of a fast neutron nuclear reactor and an adjoining vessel, use is made of a transfer hood formed by a thick tube whose inclined axis can be moved alternatively into the prolongation of the axes of two inclined ramps opening into the main vessel and adjoining vessel respectively, by the rotation of a platform of vertical axis bearing the hood and also two flaps which close the ramps when the reactor is operating, so that an assembly-transferring pot can be guided isostatically inside the ramps and the hood, the platform also possibly comprising a spare flap.Application to all assemblies forming a reactor core, such as fuel assemblies, lateral neutron screening assemblies and absorbing assemblies.

    摘要: A circuit and method for controlling a micro-electromechanical system is herein disclosed. In one embodiment of a micro-electromechanical system having top and bottom capacitor plates with a pixel plate movably positioned therebetween, a release voltage sufficient to overcome stiction forces adhering the pixel plate to one of the capacitor plates is applied to the pixel plate to cause the pixel plate to be attracted to the pixel plate opposite the capacitor plate to with which the pixel plate is in contact. After the pixel plate has moved a predetermined distance away from the capacitor plate to which it had been adhered by stiction forces, the release voltage is removed. Thereafter, an positional voltage is applied to the pixel plate to move the pixel plate to a desired location between the capacitor plates. Release and positional voltages are coupled to and decoupled from the pixel plate by one or more switching mechanisms.
