Abstract: Even if a portable information terminal is lost or stolen, a third party is prevented from illegally browsing data stored in the portable information terminal. When a control signal is received through wireless communication part and when the received control signal is an instruction signal to execute an encryption process on plaintext data stored in data memory, the plaintext data is encrypted and encrypted data is stored in the data memory. Thereafter, erasing part erases the plaintext data stored in the data memory.

Abstract: There is provided a guidance information notification apparatus in a communication network system which enables improvement of convenience to a user by dispensing with a particular operation other than a normal origination operation required when a user obtains a guidance message in an understandable language such as a native language, with a terminal unit, and by enabling the user to receive support from a communication operator of the user's contract network even when a roaming service is provided. If an originator inputs a destination telephone number with a normal origination operation at a mobile telephone set 18, a guidance information notification apparatus 22-1 notifies guidance message information in a language associated with the origination telephone number to the origination mobile telephone set 18.

Abstract: In an input signal power dynamic range compressing circuit, an input signal is distributed by a directional coupler to a linear signal transfer path and a compressing signal generating path, and in the compressing signal generating path a compressing signal, which keeps the peak-to-average-power ratio of the input signal below a predetermined value, is generated from the input signal. The compressing signal is combined by a power combiner with the input signal having passed through the linear signal transfer path.
