摘要:
The invention concerns an isolation chamber for isolating substances from the ambient. The isolation chamber comprises a first container surrounding and defining an isolation space for holding the substances and a second container surrounding the first container. A barrier space is positioned between the first and the second containers. Preferably, the pressure of the isolation space is lower than the pressure of the barrier space.
摘要:
A hydroelectric power generation system (20) generates electrical power for an electrical utilization system (72). A controller (42) obtains a requested output electrical power level from a hydro-turbine unit (70) by using a signal indicative of water head (h.sub.meas) to control speed of an asynchronous rotary converter (50) coupled to the hydro-turbine unit and to control gate position of the hydro-turbine unit. The requested output electrical power level is applied from the hydro-turbine unit via the rotary converter to the electrical utilization system. In one embodiment, the controller (42B) accesses an updatable memory wherein Hydraulic Hill Chart information is stored. In another embodiment, the controller (42C) also includes a real-time automatic governor which uses a signal indicative of ac transmission frequency to the electrical utilization system to control the output electrical power level of the rotary converter.
摘要:
A vehicle drive device with a reduction device includes an input driving unit that provides a driving force, a transmission part comprising a first rotor, a second rotor, and a stator stacked in a rotational axial direction of the input driving unit, and an output part connected to one of the first rotor or the second rotor. In particular, the input driving unit is connected to the other of the first rotor or the second rotor.
