    摘要： A power module assembly includes a reactor vessel containing a reactor core surrounded by a primary coolant. A containment vessel is adapted to be submerged in a containment cooling pool and to prohibit a release of the primary coolant outside of the containment vessel. A secondary cooling system is configured to remove heat generated by the reactor core. The heat is removed by circulating liquid from the containment cooling pool through the primary coolant.

    摘要： In integrated circuitry having both analog and digital circuits fabricated on the same substrate, switching transients produced by the digital circuitry can propagate through the substrate and induce deleterious effects in the associated analog circuitry. Such switching transients are greatly minimized by a CMOS source-coupled current-steering differential logic topology. In the preferred embodiment, gain and level shifting functions are merged, and connections to the power bus are made through constant current sources.

    摘要： Methods and apparatuses are disclosed for mass-analysis of a sample for particular analytes of interest. An electron monochromator is coupled to any of a number of different types of mass analyzer and used to generate slow electrons used to produce ions of target molecules for mass analysis. The electrons have a narrow energy bandwidth and high intensity, even at nearly zero kinetic energy levels. The median energy level of the electrons can be preset, permitting selection of specific target molecules to be ionized. Both positive and negative-ion mass analysis can be performed. Electron-capture negative-ion mass spectrometry is particularly enhanced, with a sensitivity about three orders of magnitude greater than in results obtained using conventional negative-ion equipment. Also, a buffer gas is eliminated, allowing substantial reductions in negative-ion equipment size, weight, and energy consumption. The mass analyzer can be an ion trap, making possible sensitive analysis of low concentrations of chemical analytes, such as environmental contaminants, using a hand-held instrument. Multiple mass analyzers, or combinations of a mass analyzer with other analytical instruments such a gas chromatograph, can be coupled to the electron monochromator.

    摘要： Disclosed is a device and method to control the conversion of an arbitrary resource energy into mechanical energy and subsequently into electric energy with a variable-speed generation system utilizing a turbine and a doubly-fed generator, to be connected directly to a power grid of a certain grid frequency. Via electronic control of the rotor speed by controlling the rotor winding excitation frequency, the device has the capability of providing an optimum tradeoff in maximum turbine efficiency and minimal generator losses to secure maximum efficiency of the total conversion process, irrespective of varying resource and electric load conditions. The excitation requirements of the generator are confined to moderate levels and yet a wide rotor-speed variation margin, starting from zero speed, is permitted. An integrated strategy is implemented which effectively coordinates the execution of these tasks and the independent control of the generator terminal voltage as well as the active and reactive electric power output. All signal processing as required correspondingly is carried out without the need for cumbersome measurements of turbine input and output power or generator losses.
