  • Patent number: 11135548
    Abstract: A heat exchange flow path portion is formed by alternately winding two spirally-shaped first and second heat transfer walls, with a predetermined gap interposed therebetween in the radial direction of the flow path pipe, around the outer periphery of a cylindrical flow path pipe, in which a cooling heat source is disposed in a main heat transfer flow path inside thereof. An inlet flow path and an outlet flow path for introducing compressed air into the flow path pipe and discharging compressed air from the flow path pipe are alternately formed, in the radial direction, from the gap between the heat transfer walls. Heat exchange is performed between compressed air that flows in the flow path and compressed air that flows in the flow path.

  • Patent number: 10812147
    Abstract: A method for a communication device includes determining whether a first radio frequency (RF) signal at a level of at least a first predetermined field threshold is detected. The method also includes generating a second RF signal at a level of at least a second predetermined field threshold greater than the first predetermined field threshold, when the communication device receives an instruction to generate the second RF signal and the determining determines that the first RF signal at the level of at least the first predetermined field threshold is not detected. The method further includes receiving a load modulated RF signal in response to the second RF signal.

  • Patent number: 9831923
    Abstract: A communication system and communication method enable various types of near field communication. NFC communication apparatuses have two features in that each can perform communication in two communication modes and that each can perform data transmission at a plurality of transfer rates. The two communication modes consist of a passive mode and an active mode. In the passive mode, between the NFC communication apparatuses, for example, a first NFC communication apparatus transmits data to a second NFC communication apparatus by modulating electromagnetic waves generated by itself, while the second NFC communication apparatus transmits data to the first NFC communication apparatus by performing load modulation on the electromagnetic waves generated by the first NFC communication apparatus. Alternatively, in the active mode, either of the NFC communication apparatuses transmits data by modulating electromagnetic waves generated by itself.

  • Patent number: 8514688
    Abstract: An RF (radio frequency) signal is generated at a first communication device and is modulated. A second RF signal provided to the first communication device from the second communication device is demodulated. The second RF signal is detected. The generating is actuated to initiate an active or a passive mode communication, when the detecting does not detect the second RF signal at a level of a first threshold or more, the active mode including a transmission of modulated data at the first communication device and the second communication device, the passive mode providing load modulated communication from the second communication device to the first communication device. When the first communication device receives an indication to start a communication of the active mode from the second communication device, the demodulating receives data at a level of a second threshold or higher, the second threshold being higher than the first threshold.
