摘要： The structure is arranged in such a manner that nonazeotropic mixed refrigerant is enclosed therein and a fractioning/separating device is disposed in a low pressure circuit in the main circuit of refrigerating cycle so as to conduct separation operation, the fraction/separation can be conducted at a low pressure in a separation mode, the specific volume of refrigerant gas generated in a reservoir due to heat supplied from a heater is enlarged, and the velocity of gas which moves upwards in the fractioning/separating device can be increased, causing a gas-liquid contact to be promoted. As a result, high performance separation can be conducted at reduced quantity of heat, causing the density of high boiling point refrigerant reserved to be significantly raised. Thus, the composition in the main circuit becomes a composition enriched with low boiling point refrigerant exhibiting excellent heating performance so as to satisfactorily cope with an increase in the load.

摘要： According to one embodiment, there is provided a wireless communication apparatus for making wireless connection in the first connection attempt state wherein a connection request is attempted using a predetermined frequency channel or the second connection attempt state wherein a connection request is attempted using a plurality of frequency channels. A frame generation unit generates a connection request frame which includes the first field for requesting a search of the plurality of frequency channels in response to occurrence of interference, and the second field indicating whether a corresponding frequency channel is a channel wherein occurrence of interference has been detected. A transmission unit transmits the connection request frame using the predetermined frequency channel in the first connection attempt state, and transmits the connection request frame using the plurality of frequency channels in the second connection attempt state.

摘要： According to one embodiment, a communication device includes a first wireless device configured to transmit a signal and a second wireless device configured to transmit a positive acknowledge when reception of the signal is successful. In the first wireless device, a first controller controls a first transmission module to change a first frequency channel based on a change order stored in a first storage when the positive acknowledge is not received even after the time measured by a first timer exceeds a first period. In the second wireless device, a second controller controls a second reception module to change the first frequency channel based on the change order stored in a second storage when the positive acknowledge is not transmitted even after the time measured by a second timer exceeds the first period.

摘要： According to one embodiment, a wireless communication apparatus in a first wireless system is provided with first, second and third units, and a controller. The first unit transmits frames over a frequency channel using a short or long IFS as compared with a specific one used in a second wireless system with a communication range wider than the first wireless system. The second unit receives frames over the channel. The third unit determines an error characteristic in the received frames and/or a busy status of the channel. The controller controls at least either one of whether to change the frequency channel or not, and whether to change a duration of an interframe space or not.
