  • Patent number: 11969987
    Abstract: A contacting member contacts a region of a contacted member to which a liquid composition has been applied. The contacting member has a substrate and a fluororesin fiber layer containing a fluororesin fiber. One side of the fluororesin fiber layer is directly or indirectly fixed to the substrate and another side of the fluororesin fiber layer contacts the contacted member. A ratio X/Y is less than 1.00, wherein X is a presence ratio of the fluororesin fiber in the fluororesin fiber layer on the side which is directly or indirectly fixed to the substrate and Y is a presence ratio of the fluororesin fiber in the fluororesin fiber layer on the other side which contacts the contacted member.

  • Patent number: 11807176
    Abstract: An on-board communication device, an on-board communication system, and a specific processing prohibition method for a vehicle, in which a specific service can be prevented from being provided without limitation is disclosed. The on-board communication system can perform update processing of a relay processing program for a gateway using a wireless communication path through a wireless communication device or a communication path through a communication cable connected to a connector unit. When receiving an authentication request through either of the two communication paths, the gateway performs authentication processing, and if the authentication processing was successful, the gateway receives an update relay processing program through this communication path, and performs update processing by overwriting a stored relay processing program.
