摘要:
An electric double layer capacitor and a method for manufacturing the same, in which one or more projections are formed on an inner bottom surface of a lower case, which is a concave container made of ceramic, in a the process of sequentially stacking a lower electrode, a separator, and an upper electrode in the lower case and covering the lower case with a sealing plate. It is possible to eliminate the process of injecting a bonding liquid and strongly connect the lower electrode and the upper electrode to the lower case and the sealing plate, respectively, by means of the projections, thus preventing the occurrence of a short circuit and reducing the equivalent series resistance.
摘要:
The present invention provides a radio wave detection method and a radio wave detection module for detecting illegal radio devices, and a mobile device having a radio wave detection function using the method and the module, for effectively detecting a radio signal transmitted from an illegal radio device, such as an eavesdropping device, a monitoring device, and a hidden camera used to violate privacy or leak information. In the present invention, a narrowband radio signal including a radio signal of a frequency band used by the illegal radio device is received through a single frequency antenna, and a direct current voltage value for a specific frequency of the illegal radio device is obtained by serially processing the received narrowband radio signal. Then, the obtained direct current voltage value is transmitted to a micro-controller through an analog-to-digital converter port of the micro-controller, and a data value of a digital form is outputted from the micro-controller to externally display existence of the illegal radio device through a display apparatus.
