  • Patent number: 10887133
    Abstract: A wireless gateway system includes a gateway apparatus having a gateway function and including an antenna that wirelessly communicates with a wireless field device, and a power supply apparatus separated from the gateway apparatus. The power supply apparatus converts a voltage from an external power supply to a predetermined internal voltage, supplies the internal voltage to the gateway apparatus, and relays a wired signal in conformance with a first wired communication protocol between an external controller and the gateway apparatus. The gateway apparatus operates using the internal voltage supplied from the power supply apparatus, converts a wireless signal in conformance with a wireless communication protocol received from the wireless field device to a wired signal in conformance with the first wired communication protocol, and transmits the converted wired signal to the power supply apparatus.

  • Patent number: 10807541
    Abstract: In the surface structure of an article 7 according to the present invention, a plurality of convex portions 11 are so disposed on a surface 9 as to have intervals relative to each other and a plurality of fine convex portions 21 having a diameter d and a height h smaller than those of the concave portion 11 are formed on the surface of at least the edge portion 15 of the concave portion 11. By this, when a hand touches the surface 9 of the article 7, the proper number of convex portions 21 abut on a linear object 25 constituting a fingerprint 23 of a hand's finger, to thereby allow the human being to obtain a delicate-and-soft touch feeling.
