  • Patent number: 10582604
    Abstract: A device and method for the heating of plasma by resonance using Halbach transformers for magnetic field modulation. Forming the Halbach transformers of heating to the primary magnetic field coils of confinement in a typical ring cusp confinement device configuration may reduce high-voltage breakdown along coil supports. By heating the plasma transverse to the confinement field a greater number of particle species may be retained. The primary confinement field coil support is placed outboard of the plasma cusp region by extending lobed flanges from the plates of Bitter-type primary electromagnetic field coils into the outboard region and placing the holes for the coil supports through these flanges. This arrangement of coil and flange moves plasma bombardment from the cusp region to the outboard region thus moving impurity generation by coil support bombardment from the cusp region to an outer radius where impurity effects are less detrimental.

The movable body comprises a first magnet which is permanently magnetized and has at least a first end. A nearby switching electromagnet, when energized, produces a switching magnetic field which is primarily perpendicular to the magnetization direction of the first magnet and exerts a magnetic torque on the first magnet to force the first magnet and said movable body to rotate and close an electrical conduction path at the first end. Changing the direction of the electrical current in the switching electromagnet changes the direction of the switching magnetic field and thus the direction of the magnetic torque on the first magnet, and causes the first magnet and said movable body to rotate in an opposite direction and opens the electrical conduction path at the first end.

An electromagnet provides a temporary switching magnetic field to adjust the local magnetizations across the magnetic cantilever, causing changes of magnetic forces and torques on the cantilever. As a result, the direction of a sum of torque on the cantilever is reversed. Therefore, the cantilever is switched from one stable position to the other.

  • Patent number: 7414214
    Abstract: The invention relates to a contact arrangement of a relay with a contact head (11) with a crown (17) which encloses a contact surface (15) and is raised with respect to the contact surface. According to the invention, for increasing the contact reliability with a dry switching load, this crown (17) is interrupted at a multitude of locations, by which means teeth (21) and intermediate spaces between the teeth (21) are formed. This crown contact head in the closed position of the contact arrangement bears on a crownless contact head. The contact spring (23) carrying the movable contact head is designed in a manner such that it may be subjected to torsion. The result of this is that the crown contact head (11) reliably contacts the crownless adjacent contact head (25) at the two small-surfaced contact locations, in each case with a high specific surface pressing.

  • Publication number: 20070210884
    Abstract: An electromagnet having at least one access port oriented perpendicularly to the electromagnet's central axis. The magnet has a conventional helical winding along its central axis. However, at some point along the length of the axis, the pitch of the helical winding is greatly increased in order to create a region with a comparatively low turn density. One or more ports are provided in this region. These ports provide access from the magnet's central bore to the magnet's exterior. A sample can be placed in the central bore near the ports. A beam traveling down the central bore, or through one of the radial ports, will strike the sample and be scattered in all directions. The ports allow access for instrumentation which is used to evaluate the scattered beam.

    Abstract: An electromagnetic drive has a sliding portion and a stator, the stator forming a magnetic circuit in combination with the sliding portion. The stator has an accommodating portion for supporting the sliding portion so the sliding portion can reciprocate inside the accommodating portion. A magnetic attractive force is generated by a coil to attract the sliding portion in one of the reciprocating directions. The coil generates a magnetic attractive force when energized such that either one or both of at least an outer peripheral wall of the sliding portion and at least an inner peripheral wall of said accommodating portion forms a magnetic portion made of nickel phosphide. The phosphorus content of said magnetic portion is set within a range of 5% to 15% in mass percentage.
