An object of the present invention is to provide a navigation apparatus, a vehicle information display apparatus, and a vehicle information display system, that enables a travelable range to be recognized even while a user is not riding on an electric vehicle. A vehicle information display system according to the present invention includes a navigation apparatus and a vehicle information display apparatus. The navigation apparatus includes: a storage section mounted on an electric vehicle, for storing map information and a destination; an own vehicle position information acquisition section for obtaining own vehicle position information; a remaining power amount acquisition section for obtaining a remaining power amount; a travel cost calculation section for calculating a power cost based on the map information, the destination, and the own vehicle position information; a travelable range calculation section for calculating a travelable range based on the power cost and the remaining power amount; and a communication section for transmitting vehicle information including the travelable range to the outside. The vehicle information display apparatus includes: a communication section installed outside the electric vehicle, for receiving the vehicle information; and a control section for outputting the vehicle information.

The carry-line comprises a plurality of MOSFETs connected in series. MOSFETs precharge each node when they receive precharge signals /PR. In the case of high-order priority designated mode, when input signals are given for turning on MOSFETs located between one end of the high-order bit side of the carry-line, the control circuit discharges the intermediate node separately from the carry-line. In the case of low-order bit priority designated mode, when input signals are given for turning on MOSFETs located between one end of the low-order bit side of the carry-line and the intermediate node, the control circuit discharges the intermediate node separately from the carry-line.

The same bit lines are used in common to a fixed data cell array and a memory cell array. The output section of the fixed data cell array is connected to an output circuit, just like the output section of the memory cell array. In response to signal CON supplied from a computer, an array selector examines the states of the arrays and performs switching between the state where one of the arrays can be selected and the state where neither of them can be selected. In the case where an externally-programmable memory, such as an EPROM, is employed, a write control circuit operates with respect only to the memory cell array, and prohibits data from being written in the fixed data cell array. The fixed data cell array is pre-programmed as a nonvolatile memory by programming means different from that used for programming the cells of the memory cell array.

A level conversion circuit includes first to nth circuits, each having an input terminal and first to nth output terminals where n is an integer, and first to nth signal lines coupled to the first to nth circuits. Each of the first to nth circuits comprises a part for outputting a first voltage to the first output terminal and outputting a second voltage to the second to nth output terminals other than the first output terminal when an input signal applied to the input terminal is at a first level and for maintaining the first to nth output terminals in high-impedance states when the input signal is at a second level different from the first level. The first output terminal of each of the first to nth circuits is connected to one of the first to nth signal lines so that first output terminals of the first to nth circuits are connected to mutually different signal lines. The second to nth output terminals of each of the first to nth circuits are connected to (n-1) signal lines other than the one of the first to nth signal lines to which the first output terminal is connected.

A mobile telecommuncations system has multiple base stations each defining a miniature service zone and capable of communicating with mobile stations present in the service zone over a radio link. Geographically associated ones of the base stations are spaced apart from each other by an area which is not responsive to electromagnetic waves on the radio links, whereby the base stations are allowed to share the same frequency for the electromagnetic waves. The base stations are interconnected to an on-road vehicle telecommunications network which switches communications to the base stations.
