    Abstract: Titanium oxide particles comprising particulate titanium oxide substrate having a zinc oxy compound or a combination of a zinc oxy compound and a silicon oxy compound supported thereon. They can be produced by adding a zinc compound or a combination of a zinc compound and a silicon compound together with an alkali to a dispersion of particulate titanium oxide substrate to neutralize the zinc compound or the combination of the zinc compound and the silicon compound in said dispersion, then separating and drying the resultant product. They are useful for pigments, catalysts, catalyst supports and adsorbents, and particularly excellent in deodorizing performance by removing malodorous gases such as ammonia, methyl mercaptan, hydrogen sulfide, trimethylamine, methyl sulfide and acetaldehyde through decomposition and adsorption thereof, so that they are useful as white deodorants for sanitary objects such as paper diaper and sanitary napkins which come to directly contact with the skins of human beings.

    Abstract: A GPS receiver includes a power supplying status detector for deriving a power-on or power-off signal by detecting a power supplying status of the GPS receiver, a clock for measuring time, a memory controller for controlling a nonvolatile memory upon receiving the power-off signal to store a time measured by the clock when the power is turned off or a time when the last ephemeris data is obtained and the last ephemeris data, and a position calculating circuitry for calculating the position of the user station upon receiving the power-on signal. A time duration is calculated from the time measured by the clock and the time stored in the nonvolatile memory. If it is determined that the measured time duration is shorter than a predetermined period of time, the positioning is performed based on the respective ephemeris data stored in the nonvolatile memory, whereas if it is determined that the measured time duration is no less than the predetermined period of time, the positioning is performed based on ephemeris data newly collected from the respective GPS satellites.
