  • Publication number: 20110246610
    Abstract: Tour guide contents stored in a tour guide apparatus carried by a user at a tour destination are provided with points of interest information and map data. This information includes latitude and longitude information for the site of each point of interest, and information on the providers of the information and the categories of information. The latitude and longitude information is provided for each site in relation to map data. By matching these pieces of latitude and longitude information to the map data, points of interest information can be laid out on the map and displayed. This makes it possible to select interesting site information to be displayed on the map based on the information provider, for example, points of interest information provided by provider A for restaurants and another set of information provided by provider B for hotels.

  • Patent number: 7557216
    Abstract: To provide an industrially advantageous process for producing 5-chloro-2,4-dihydroxypyridine, which is an inhibitor acting on a biodegradation enzyme that biodegrades an anti-malignant-tumor agent 5-fluorouracil. The process is carried out under mild conditions with a small number of steps and produces less industrial waste. The process employs a 5-chloro-1,3-dioxin-4-one derivative (2) as a starting substance to thereby form a pyrone derivative (4) represented by formula (4): (wherein R3 and R4, which are identical to or different from each other, each represent a C1 to C6 linear-chain or branched-chain alkyl group, or a silyl group having a C1 to C6 linear-chain or branched-chain alkyl group), and subsequently, 5-chloro-2,4-dihydroxypyridine (1) is produced from the pyron derivative.
