    摘要: The combustor (1) comprises a stationary structure (2; 102) and at least one tubular rotor (3; 3', 3") supported rotatably about an axis (4) by the structure (2; 102) by means of contactless suspension devices (5-8; 5', 5", 6', 6") there being formed within this rotor at least one combustion chamber (20; 20', 20") having at least one orientated lateral outflow aperture (21; 22; 23, 24) for the ejection of the combustion gases. The rotor (3; 3', 3") has a narrow circumferential slot (30; 30', 30") through which there extend at least one controlled stationary injector (31; 31', 31") of fuel and combustion agent and an associated igniter (32; 32', 32") which is also stationary.
    A control unit (ECU; 35) operates the injector (31; 31', 31") and the igniter (32; 32', 32") according to predetermined procedures, in such a way as to generate a detonation wave which is propagated in the chamber (20; 20', 20"), and to cause the rotor (3; 3', 32) to rotate as a result of the thrust due to the combustion gases emitted through the lateral outflow aperture (21, 22; 23, 24).

    摘要: To provide a magnetic bearing device capable of lowering the costs required for the manufacture, installation, or the like of a turbo molecular pump by reducing the number of elements of an amplifier circuit that drives, through excitation, electromagnets as well as the number of wires of a cable that connects the each electromagnet and the amplifier circuit to each other, and a turbo molecular pump with the magnetic bearing device mounted thereto. One end of an electromagnet coil 151 is connected to a common node R. Also, the other end thereof is connected to an amplifier circuit 410 composed of one transistor 411 and one diode 415. Further, the one end of the electromagnet coil 151 is common with respect to each of the electromagnets, and the common node R is controlled by an intermediate-voltage maintaining circuit 451 so as to maintain an intermediate voltage Vc.

    摘要: A valve assembly comprises a valve opening (4) which can be sealed and un-sealed by movement of a membrane 6; a force generator, such as an electromagnetic force generator comprising a solenoid (20) and anchor (18) arrangement; and a shaft (8) that is operably connected to the membrane (6) and which is movable along a movement axis (C) under the influence of the generated force to move the membrane (6) and thereby regulate the degree of opening of the valve (44). Bearing assemblies (14;16) are provided to procure a magnetic suspension of the shaft (8), permit its movement along the axis (C), and also to optionally procure a magnetic biasing of the shaft (8) in a direction along the axis (C), particularly in the absence of a generated force.
