Abstract: Disclosed is a mobile terminal incorporating a battery pack utilized as power supply. The mobile terminal includes a positive terminal connected to a battery pack positive electrode, a negative terminal connected to a battery pack negative electrode, a data communication terminal communicating with a circuit in the battery pack, a charge control unit controlling charging of the battery pack via the positive terminal, and a reference voltage output unit outputting reference voltage. The terminal further includes a dividing resistor and a thermistor connected in series between the reference voltage output unit and the negative terminal, a temperature detector detecting temperature, and stopping charging of the battery pack based on the detected temperature, and a switching device controlling the voltage at the predetermined portion.

Abstract: Disclosed is a mobile phone terminal with a battery pack containing a retraceable battery as power supply, and transmitting and receiving radio-signals to and from a mobile phone system base transceiver station. The mobile phone terminal includes a data communication terminal communicating data with the battery pack, an intermittent receiving processor periodically carrying out intermittent receiving processing via the base transceiver station when the mobile phone terminal is in a standby operation, and a battery status determining unit transmitting, while the intermittent receiving processor is carrying out intermittent receiving processing, an activating signal to the battery pack via the data communication terminal and reading battery status data from the activated battery pack.

Abstract: A user identification module (UIM) 12 having a plurality of storage areas that may be built into or mounted in a mobile terminal 11. A contents server 19, upon receipt of a distribution request from the mobile terminal 11, may distribute a program or data used at the time of program execution through a network including a radio network. The program may be encrypted twice by the contents server 19. During distribution, the program may be decrypted a first time by a distribution management server 16. The program may be decrypted a second time by the UIM 12. The decrypted program and the data may be stored in one of a plurality of separate and independently operated memory blocks of the UIM 12 and not through the control unit of the mobile terminal 11. The program may be enabled for execution by the UIM 12 at the direction of the distribution management server 16.

Abstract: A semiconductor integrated circuit device is disclosed that includes a signal processing unit having a nonvolatile memory and a detection unit; plural oscillation sources outputting plural oscillation signals; a selection control unit that selects one of the oscillation signals output by the oscillation sources according to a selection signal, and controls a transfer timing for transferring circuit setting information from the nonvolatile memory to the detection unit and an operations start timing for starting signal processing operations of the signal processing unit according to the selected oscillation signal.

Abstract: A disclosed semiconductor integrated circuit device includes a digital circuit and an analog circuit formed on one semiconductor substrate; a guard band configured to prevent noise generated in the digital circuit from being transmitted to the analog circuit; a first power supply terminal configured to supply a power-supply voltage to the analog circuit; a first ground terminal configured to supply a ground potential to the analog circuit; a second power supply terminal configured to supply the power-supply voltage to the digital circuit; a second ground terminal configured to supply the ground potential to the digital circuit; and a filter circuit positioned between the second power supply terminal, the second ground terminal, and the digital circuit and configured to remove the noise transmitted from the digital circuit.

Abstract: Since telephone terminals 301, 302 and 303 are used as control terminals in a network information system by using DTMF signals (or packet signals), there is no need for a specially designed terminal or computer system, and any user (or researchee) who has the telephone terminal can respond to a server. In addition, by using a calling function, which is essentially provided to the telephone terminals, when the system is in use, audio communication can be easily established between users.

Abstract: A UIM 12 having a plurality of storage areas is built into or mounted in a mobile terminal 11. A contents server 19, upon receipt of a distribution request from the mobile terminal 11, distributes a program or data used at the time of program execution or the program itself through a network including a radio network. This program and the data or the program itself are stored in the storage area of the UIM 12 and not through the control unit of the mobile terminal 11.
