  • ACTIVE TRANSMIT ELEMENTS FOR MRI COILS AND OTHER ANTENNA DEVICES, AND METHOD
    Publication number: 20140097846
    Abstract: Apparatus and method that includes amplifiers for transceiver antenna elements, and more specifically to power amplifying an RF (radio frequency) signal using a distributed power amplifier having electronic devices (such as field-effect transistors) that are thermally and/or mechanically connected to each one of a plurality of antenna elements (also called coil elements) to form a hybrid coil-amplifier (e.g., for use in a magnetic-resonance (MR) imaging or spectroscopy machine), and that is optionally adjusted from a remote location, optionally including remotely adjusting its gains, electrical resistances, inductances, and/or capacitances (which controls the magnitude, phase, frequency, spatial profile, and temporal profile of the RF signal)—and, in some embodiments, the components are compatible with, and function in, high fields (such as a magnetic field of up to and exceeding one tesla or even ten tesla or more and/or an electric field of many thousands of volts per meter).

  • SINGLE PHASE INDUCTION MOTORS INCLUDING ALUMINUM WINDINGS AND HIGH PERMEABILITY LOW CORELOSS STEEL
    Publication number: 20220069686
    Abstract: A single phase induction motor includes a stator core having a stator yoke and a plurality of teeth extending toward a central opening. The plurality of teeth are spaced apart from one another and define multiple slots between the teeth for receiving windings of the single phase induction motor. The stator core includes a high permeability low coreloss (HPLC) steel having a relative permeability of greater than or equal to 3000 at 1.5 Tesla and 60 Hertz, and a coreloss of less than or equal to 1.75 watts/lb at 1.5 Tesla and 60 Hertz. The motor also includes multiple windings located within the plurality of slots and wrapped around the plurality of teeth of the stator core. Each of the multiple windings include aluminum wire. The motor further includes a rotor body located concentrically within the stator core and including an external surface that faces the stator core.

  • Suction muffler in reciprocating compressor
    Publication number: 20030127282
    Abstract: The invention relates to a suction muffler in a reciprocating compressor. The suction muffler is installed over a suction valve in order to attenuate complex sound pressure (noise) such as vibrational noise, valve sonance and flowing noise and pulsative noise which is produced from the suction valve when refrigerant gas in low temperature and pressure ejected from an evaporator is sucked into a cylinder via the suction valve and a suction portion of the cylinder. Further, a Tesla valve having the two distribution paths is mounted within the suction muffler in order to attenuate the complex sound pressure (noise) such as vibrational noise, valve sonance and flowing noise and pulsative noise produced from the suction valve while prevent the reflow of the refrigerant gas into the suction muffler from the suction valve.
