摘要： PROBLEM TO BE SOLVED: To save the power of a communication equipment by providing a power supply control part for controlling the extent of operation energy corresponding to the reception intensity of prescribed information in the communication equipment. SOLUTION: The power supply control part 8 of the communication equipment 2 adjusts the size of the operation energy to be supplied to a card corresponding to the output of an amplifier 39 changed corresponding to the change of the size of return signals from the card and changes a communication area to a minimum range required for data communication during data communication. Also, since the communication area is changed to the minimum range required for the data communication during data communication, even in the case that the other non-contact communication system is adjacent, the interference of the data communication with the other non-contact communication system is prevented. Also, since the power supply control part 8 adjusts the size of the operation energy to be supplied to the card corresponding to the change of the size of the return signals from the card, operation power supplied from the power source circuit of the card to each constitution of the card is almost fixed.

摘要： PURPOSE:To obtain the converting system for a word whose selection efficiency is satisfactory by storing in advance concept information, comparing the concept information and concept information of each homonym, and extracting a matched homonym. CONSTITUTION:Reading of a character is inputted by a character input means 1 and subjected to morpheme analysis and syntax analysis, and converted to a notation of the corresponding word by a converting means 2. In such a state, if there is a homonym, a candidate table is generated, and subsequently, a sentence external word table is generated and latched to storage means 3a. Next, whether a match candidate exists in concept information or not is checked, based on a comparing means 3b, and if there is the match candidate exists, its candidate is selected and a result of selection by a homonym selecting means 3 is outputted by a character output means 4. In such a way, the word of a candidate can be selected by utilizing many information, and the efficiency for selecting a homonym can be improved.

摘要： PROBLEM TO BE SOLVED: To more easily and inexpensively manufacture a loop antenna by making the intensity of a magnetic field near an antenna to be strong and that a remote place to be weak and eliminating the need of adjusting the total area, the shapes and the line lengths of two loop antennas. SOLUTION: First and second loop antennas 1 and 2 which are closely arranged are installed. The total areas, the shapes and the line lengths of the first and second loop antennas 1 and 2 are equal. The directions of currents flowing in the first and second loop antennas 1 and 2 are made to be opposite and therefore phases are set to be opposite. The first and second loop antennas 1 and 2 are connected in parallel and they share power feeding points 3. The first and second loop antennas 1 and 2 are formed of conductors which are started from a pair of power feeding points 3 installed in one place, distributed and returned to the power feeding points 3 again.

摘要： PROBLEM TO BE SOLVED: To quickly transfer various navigation information to a user of an optional traffic facility at an optional position by receiving and displaying the present position information transmitted from a position information transmitter of the present position with a dedicated card in a station precinct of the optional traffic facility or in a train. SOLUTION: A processor in a ticket window reader/writer 1 writing the utilization zone information from station A to station B on a dedicated card 2 transmits the utilization zone information of a traffic facility and records it on the dedicated card 2. A position information transmitter 3 in a station precinct or in a train reports and displays the installation position to the dedicated card 2 and reports the present position of the carrier of the dedicated card 2. The dedicated card 2 transmits the utilization zone information before it receives the guidance information based on the utilization zone information recorded on the dedicated card 2 and read by a guidance information transceiver 5 in the station precinct, and the guidance information transceiver 5 receiving the utilization zone information retrieves a database memory and extracts and transmits the guidance information based on the present position of the dedicated card 2.
