Abstract: A vehicle-mounted message apparatus comprising a device for converting a voice into an electrical signal, storing it in a memory, and reproducing and confirming automatically the stored data after being stored, a device for reproducing the stored data into a voice when required, and a device for erasing the stored data after reproducing the same for confirmation in response to a starting switch.

Abstract: An improved process for continuously preparing terephthalic acid by a catalytic liquid-phase oxidation which comprises recycling a part of the mother liquor of the oxidation product to the catalytic liquid-phase oxidation zone either as such or after concentration, concentrating the remainder of the mother liquor, until the amount of acetic acid in the resulting bottoms becomes not more than 5% by weight based on the weight of the residual bottoms and the amount of benzoic acid bottoms becomes not less than 15% by weight based on the weight based on the weight of the residual bottoms, contacting the bottoms in the hot and molten state with 2 to 5 times their weight of water, and rapidly cooling the bottom to a temperature of not more than 50.degree.C., separating an aqueous solution containing the catalyst from the resulting granular solid mixture and recycling the aqueous solution to the catalytic liquid-phase oxidation zone.
