  • VEHICLE DISPLAY CONTROL DEVICE
    Publication number: 20240239194
    Abstract: A vehicle display control device includes a detection unit, a reception unit, and a control unit. The detection unit detects lane markings in the target lane in which the vehicle is traveling. The reception unit receives a display mode from a vehicle occupant. The control unit causes the display unit to display, in the received display mode, an execution image indicating whether lane keeping control in which the vehicle travels staying in the target lane, is executed.

  • Molten salt composition, electrolyte, and electric storage device, and method for increasing a viscosity of liquid molten salt
    Patent number: 10535897
    Abstract: The object of the present invention is to provide the gelatinous, molten salt having a high ion-conductivity and an excellent heat resistance. The object of the present invention can be solved by the inorganic nanofibers having a functional group which inter-molecularly interacts with the molten salt on the surface thereof, and the molten salt composition comprising molten salt; or the method for increasing a viscosity of liquid molten salt characterized in that the inorganic nanofibers having a functional group which inter-molecularly interacts with the molten salt in the surface thereof is added to the liquid molten salt.
