20120200167 | ANTENNA DEVICE AND COMMUNICATION DEVICE - An antenna device that is able to maintain the resonance frequency approximately constant despite changes in temperature to provide for stabilized communication is provided. The antenna device includes an antenna coil that receives a magnetic field transmitted from a reader/writer and a capacitor. The antenna device also includes a magnetic sheet formed at a face-to-face position with respect to the antenna coil and configured for changing the inductance of the antenna coil. The capacitor has a temperature characteristic in which the capacitance of the capacitor is changed with changes in temperature. The magnetic sheet is formed of a magnetic material having a temperature characteristic in which the inductance of the antenna coil is made to be changed with an opposite sign of change to that of the capacitance of the capacitor that is changed with changes in temperature in the working temperature range. | 08-09-2012 |
20120204414 | METHOD FOR PRODUCING ANTENNA DEVICE - A method for manufacturing an antenna device is provided. The manufacturing method includes forming an antenna circuit so that the resonance frequency of the antenna circuit will be lower than an oscillation frequency of the reader/writer and affixing a magnetic sheet to an antenna coil via an adhesive. The antenna circuit includes the antenna coil that receives the magnetic field transmitted from the reader/writer and a capacitor electrically connected to the antenna coil. The magnetic sheet is at a face-to-face position with respect to the antenna coil and is configured to change the inductance of the antenna coil. The adhesive is of a film thickness to change the inductance so that the resonance frequency of the resonance circuit will be coincident with the oscillation frequency depending on the spacing between the antenna coil and the magnetic sheet. | 08-16-2012 |
20120206307 | ANTENNA DEVICE AND COMMUNICATION DEVICE - An antenna device includes an antenna coil that receives a magnetic field transmitted from a reader/writer and a capacitor. The antenna device also includes a magnetic sheet formed at a face-to-face position with respect to the antenna coil and configured for changing the inductance of the antenna coil. The capacitor has a temperature characteristic in which the capacitance of the capacitor is changed with changes in temperature. The magnetic sheet is formed of a magnetic material having a temperature characteristic in which the inductance of the antenna coil is made to be changed with an opposite sign of change to that of the capacitance of the capacitor that is changed with changes in temperature in the working temperature range. In this manner, the resonance frequency of the antenna circuit in the working temperature range may be brought approximately into coincidence with the oscillation frequency of the reader/writer. | 08-16-2012 |
20120227248 | METHOD FOR PRODUCING ANTENNA DEVICE - A method for manufacturing an antenna device may include a first step of forming an antenna circuit so that the resonance frequency of the antenna circuit will be lower than an oscillation frequency of the reader/writer. The antenna circuit includes an antenna coil that receives the magnetic field transmitted from the reader/writer and a capacitor electrically connected to the antenna coil. The manufacturing method also includes a second step of affixing a magnetic sheet to the antenna coil via an adhesive. The magnetic sheet is at a face-to-face position with respect to the antenna coil and is configured to change the inductance of the antenna coil. The adhesive is of a film thickness to change the inductance so that the resonance frequency of the resonance circuit will be coincident with the oscillation frequency depending on the spacing between the antenna coil and the magnetic sheet. | 09-13-2012 |
20150260862 | RESIDUAL SEISMIC-RESISTANT PERFORMANCE EVALUATION SYSTEM - A residual seismic-resistant performance evaluation system includes a seismograph including a seismic intensity sensor, a network interface, a storage, an A/D converter, a temporary storage means and a CPU; a data processing terminal for recording and processing measurement data; and a data processing server for evaluating residual seismic-resistant performance based on the measurement data. The system causes the data processing terminal to perform the steps below: a) calculating seismic intensity data based on the measurement data; b) setting a threshold value for the seismic intensity data; determining whether or not the seismic intensity data exceeds the threshold value; and d) transmitting the seismic intensity data exceeding the threshold value to the data processing server. The system causes the data processing server to perform steps below: g) requesting at least one of the seismograph and the data processing terminal to provide the measurement data; and h) receiving the measurement data transmitted according to the request. | 09-17-2015 |
