According to an aspect of the invention, there is provided a communication device including: a communication unit configured to communicate with an opponent by an electric communication network; a vibration unit configured to generate a vibration at a predetermined vibration pattern; a storage unit configured to store identification information about the opponent; a display unit configured to listing the identification information; an operation unit configured to accept an operation for moving a cursor which points at one of identification information listed by the display unit; and a control unit configured to activate the vibration unit in accordance with the one of identification information pointed at with the cursor.

Communication device

When a remaining capacity of a battery is displayed by remaining capacity display control means, operation state discrimination function discriminates an operation state of an apparatus and also discriminates whether battery output voltage Vout is greater than discrimination value Vp when the apparatus is in reception indication operation. If the battery output voltage Vout is greater than the discrimination value Vp, remaining capacity of the battery corresponding to the battery output voltage Vout in a standby state immediately before the start of the reception indication operation is displayed on LCD. If the battery output voltage Vout is equal to or smaller than the discrimination value Vp, the remaining capacity of the battery corresponding to the battery output voltage Vout of this time is displayed as it is on the LCD.

Battery capacity indication circuit and indication method thereof, and battery-operated electronic device and cellular communication terminal apparatus comprising the indication circuit

A text mail system in which a pseudo destination subaddress randomly generated at a call receiver side at the time of receiving an incoming call from an integrated services digital network is used to manage the storing or reading out operation of various sorts of messages in a mail box. The text mail system, which uses the pseudo destination subaddress as a box number based on the property that the pseudo destination subaddress is randomly given for each incoming call, can secure a high mail confidence.
