  • Magnetic field regenerator
    Patent number: 10368429
    Abstract: An example particle accelerator includes the following: a voltage source to provide a radio frequency (RF) voltage to a cavity to accelerate particles from a plasma column, where the cavity has a magnetic field causing particles accelerated from the plasma column to move orbitally within the cavity; an extraction channel to receive the particles accelerated from the plasma column and to output the received particles from the cavity; and a regenerator to provide a magnetic field bump within the cavity to thereby change successive orbits of the particles accelerated from the plasma column so that, eventually, particles output to the extraction channel. The magnetic field is at least 6 Tesla and the magnetic field bump is at most 2 Tesla.

    Publication number: 20200075207
    Abstract: A superconducting magnet according to one embodiment includes: a coil including a superconducting layer having a first portion and a second portion, and a joining portion; and a cryostat in which the coil is stored. The first portion and the second portion are located in a termination portion. The superconducting layer forms a closed loop by superconducting joining of the first portion and the second portion at the joining portion. The superconducting layer is made of a high-temperature superconductor. A current flows through the joining portion in a superconducting state when a magnetic field equal to or greater than 1.0 tesla and equal to or less than 5.0 tesla is applied to the joining portion at 77 kelvin. The cryostat is configured such that a temperature inside the cryostat is equal to or greater than 2.0 kelvin and equal to or less than 77 kelvin.

  • Suction muffler in reciprocating compressor
    Patent number: 6691823
    Abstract: A suction muffler in a reciprocating compressor is installed over a suction valve to attenuate complex sound pressure (noise) such as vibrational noise, valve sonance, flowing noise and pulsative noise produced from the suction valve when low temperature, low pressure refrigerant gas ejected from an evaporator is sucked into a cylinder via the suction valve and a suction portion of the cylinder. A Tesla valve having two distribution paths is mounted in the suction muffler to attenuate the complex sound pressure (noise) while preventing the reflow of the refrigerant gas into the suction muffler from the suction valve. As a result, the Tesla valve also enhances the cooling ability of the compressor and the attenuation effect.
