Abstract: A fluid heating device includes a container in which fluid is supplied between an inner surface of an outer cylindrical member and outer surfaces of the inner cylindrical members, lamp heaters arranged in an inner cylindrical members, a nozzle member arranged on a leading end side of the lamp heaters and having an air supply port, and a guide mechanism that guides gas supplied from the air supply port of the nozzle member. The inner cylindrical members include a central inner cylindrical member arranged at a center of the outer cylindrical member, and peripheral inner cylindrical members arranged around the central inner cylindrical member. The lamp heaters include a central lamp heater arranged in the central inner cylindrical member and peripheral lamp heaters respectively arranged in the peripheral inner cylindrical members. The guide mechanism guides the gas to a leading end side of the central lamp heater.

Abstract: A travel guidance system for a vehicle having a plurality of on-board batteries includes: a travel start location obtaining unit; a destination obtaining unit; a charging facility candidate location obtaining unit for obtaining location information for charging facility candidates; a remaining amount calculating unit for calculating, for each charging facility candidate, the amount of energy which will remain in the on-board batteries upon arrival at the charging facility candidate; a charging facility selecting unit for selecting a charging facility suitable for leaving the on-board batteries based on the travel start location, the destination, the location information for charging facility candidates, and the amounts of the remaining energy in the on-board batteries calculated for each charging facility candidate; and a charging facility notification unit for communicating the location information for the selected charging facility.
