The present invention is directed generally toward computer-implemented methods for targeting objects in a gaming system. The process is based on the gas phase, noncatalytic fluorination of hydrochlorofluoropropenes to form hydrofluoropropenes. Such single-separation device-dependent colors, in one embodiment, comprise cyan, magenta, yellow and black. The controller performs a refresh operation when a relative humidity calculated on the basis of the temperature and humidity detected by the interior temperaturehumidity detection section immediately after the image forming apparatus is connected to the external power source is higher than the preset value.
