Abstract: A niobium-titanium-based oxide includes niobium-titanium-based oxide particles, wherein an Si2p peak area and an Nb3d peak area, as measured by X-ray photoelectron spectroscopy for the niobium-titanium-based oxide particles, satisfy a ratio A of 0.40?A?1.0, provided that the ratio A is the Si2p peak area/the Nb3d peak area.

Abstract: An automatic control system for a vehicle such as a fork lift truck automates the transportation, loading and unloading operations of the vehicle in a work area. Leader cables disposed in the work area are supplied with instruction signals of respectively different frequencies from terminal units in response to commands from a central control device. Any cable or a combination of two cables forms a ehicle guideway along which the travel of the vehicle is controlled by instruction signal pickup coils on the vehicle and along which loading and unloading stations for the vehicle are located. Loading and unloading are effected without using the leader cables, the necessary instruction signals then being received from the central control device by the vehicle from a coil disposed at the loading and unloading station.
