  • Publication number: 20260014470
    Abstract: In a game display method, a virtual game scene of a virtual environment from a target perspective of a first virtual character is output for display on a game interface. The virtual game scene includes a second virtual character. Based on a virtual control region formed by the first virtual character triggering a time-stop state in the virtual game scene, a remaining effective duration of the virtual control region is output for display on the game interface. The second virtual character located within the virtual control region is placed in a restricted state. The remaining effective duration of the virtual control region is increased based on an attack operation performed by the first virtual character on the second virtual character satisfying a preset time-stop continuation condition. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.

  • Patent number: 11348763
    Abstract: Disclosed is a corrosion-resistant structure for a gas delivery system in a plasma processing apparatus. By providing a plating layer of corrosion-resistant material at the parts including the gas channel to avoid reacting with the delivered corrosive gas, metal and particle contaminations are reduced. By reversely mounting nozzles such that they reliably cover the plating layer inside the gas outlet holes, the disclosure prevents the corrosion-resistant material from being damaged by the plasma generated inside the cavity. By forming a corrosion-resistant yttrium oxide coating at the surfaces of the nozzles exposed to the cavity, the disclosure prevents the plasma from eroding the nozzles. The disclosure further leverages a flexible corrosion-resistant material, such as Teflon, to the sealing surfaces of the liner in contact with the dielectric window and the cavity, which improves the overall sealing effect of the liner.
