    摘要： The present invention provides an oil-returning device and a accumulator, the oil-returning device including an outlet pipe and a filtering component, the outlet pipe having an bent arc portion which is provided with a positioning hole, the filtering component including a filtering screen and a filtering screen base with an oil-returning orifice, and being fixedly installed in the positioning hole, wherein an effective cross section area Sn of an inner space of the outlet pipe at a position where the filtering component is installed is in a range of 50%˜90% of an original effective cross section area S0 of the inner space of the untreated outlet pipe at a position where the filtering component is to be installed. The accumulator includes a hermetically sealed container, a inlet pipe and the oil-returning device, wherein in the case of a given diameter of the outlet pipe and a diameter of the oil-returning orifice, appropriate oil-returning capacity will be attained by setting the effective cross section area of the inner space at the oil-returning orifice of the outlet pipe, and thus the production has significant versatility and can meet the requirements of various refrigeration systems.

    摘要： A portable electronic device is provided that has a hybrid antenna. The hybrid antenna may include a slot antenna structure and an inverted-F antenna structure. The slot antenna portion of the hybrid antenna may be used to provide antenna coverage in a first communications band and the inverted-F antenna portion of the hybrid antenna may be used to provide antenna coverage in a second communications band. The second communications band need not be harmonically related to the first communications band. The electronic device may be formed from two portions. One portion may contain conductive structures that define the shape of the antenna slot. One or more dielectric-filled gaps in the slot may be bridged using conductive structures on another portion of the electronic device. A conductive trim member may be inserted into an antenna slot to trim the resonant frequency of the slot antenna portion of the hybrid antenna.

    摘要： A handheld electronic device is provided that contains wireless communications circuitry. The wireless communications circuitry may include antennas. An antenna in the handheld electronic device may have a ground plane element. A slot antenna resonating element may be formed from an opening in the ground plane element. A near-field-coupled antenna resonating element may be electromagnetically coupled to the slot antenna resonating element through electromagnetic near-field coupling. A transmission line may directly feed the slot antenna resonating element. The transmission line may indirectly feed the near-field-coupled antenna resonating element through the slot antenna resonating element. The slot antenna resonating element may have one or more associated resonant frequencies and the near-field-coupled antenna resonating element may have one or more associated resonant frequencies. The antenna may be configured to cover one or more distinct communications bands.
