Patent number: 11135548Abstract: 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.Type: GrantFiled: May 30, 2018Date of Patent: October 5, 2021Assignee: SMC CORPORATIONInventors: Tomoyuki Iwata, Tetsuo Sakaguchi, Kunihide Fujii, Shunsuke Uchida

Patent number: 9831923Abstract: 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.Type: GrantFiled: October 19, 2016Date of Patent: November 28, 2017Assignee: SONY CORPORATIONInventors: Yoshihisa Takayama, Susumu Kusakabe, Kazushige Tsurumi, Tadashi Morita, Kunihide Fujii
