  • Patent number: 11970134
    Abstract: A vehicle control system includes a processing device provided in a vehicle, an application unit (app unit) implemented by execution of an application program by the processing device, a function restriction determining unit determining whether function restriction on the app unit is to be performed based on a used key code, and a function restriction applying unit instructing the app unit to apply a determination result of the determination. The function restriction determining unit determines whether the function restriction on the app unit is to be performed based on a key code of the used electronic key at a plurality of predetermined times, and the function restriction applying unit instructs the app unit to apply the determination result upon activation of the application unit and when a notification of the determination result is received from the function restriction determining unit after the activation.

  • Patent number: 6432583
    Abstract: According to the present invention, there are disclosed: a process for producing an anode material for lithium secondary battery, comprising graphite particles and a crystalline carbon layer covering the whole surfaces of the graphite particles, wherein the whole surfaces of the graphite particles are covered with a carbon layer in a state that the surfaces of the graphite particles and the carbon 002 plane of the carbon layer are parallel, which process comprises subjecting graphite particles to a treatment for chemical vapor deposition in a fluidized bed type reactor at 900 to 1,200° C., using a mixed gas consisting of an organic substance gas and an inert gas, the molar concentration of the organic substance gas in the mixed gas being 2 to 50%; and an anode material for lithium secondary battery, produced by the above process.
