Abstract: A vehicle navigation apparatus in accordance with the present invention includes a CDROM (2) for storing all the data required for navigation processing such as maps and voice data, and a buffer (4-1) for accessing CDROM (2) to prepare beforehand a phrase necessary for the navigation guidance. A control device (1) selects appropriate phrases corresponding to the present vehicle position and reads out the selected phrases from the buffer, (4-1) successively, in response to a request signal supplied from a request sensor (7) which is output in response to the driver's request. The thus processed navigation information data is transformed into voice signals through a decoder (4-2) and output from a speaker (5) as a voice response. The control device (1) checks whether or not a phrase prepared in the buffer (4-1) is a frequently used phrase and replaces this phrase with a new phrase if this phrase is not frequently used.

Abstract: The invention is a liquid food for supplying protein principally containing protein, seasonings, flavoring materials and water, wherein it contains 5 to 15% by weight of lactalbumin as the protein. The lactalbumin is obtained by heating to denature under conditions so as to form a cloudy solution. The food is useful for undernourished patients who suffer from hypoproteinemia, hypoalbuminemia or common healthy men who need protein so as to desire to supply nutritious food and develop their muscles.
