  • Patent number: 11404759
    Abstract: A connection structure includes a dielectric waveguide line and a rectangular waveguide. The dielectric waveguide line transmits a high-frequency signal in a transmission region surrounded by a first conductor layer, a second conductor layer, and two arrays of via hole groups. A coupling window is formed in the second conductor layer.

  • Patent number: 11300219
    Abstract: A variable-capacity compressor control valve is configured for easily regulating the opening degree of an in-valve release passage, and thus can effectively reduce internal circulation of refrigerant within the compressor and effectively improve the operation efficiency of the compressor. An in-valve large-opening release passage with a relatively large opening degree, which is used during the compressor actuation time, and an in-valve small-opening release passage with a relatively small opening degree, which is used during both the compressor actuation time and the normal control time (i.e., Pd?Pc control time), are formed using different passages.
