Patent number: 7541779Abstract: A portable electronic device and a mobile communication terminal, whose surface temperature does not increase while being charged regardless of the type of a charger for charging a storage battery being mounted therein. When a cell-phone unit, which has a radio section being a heat source and operates with a battery pack mounted therein as a power source, is connected to an external power feeder with the battery pack being mounted, the battery pack is charged by current from the external power feeder. When the battery pack is charged while the radio section is operating, the value of the charging current to charge the battery pack is reduced less than that when the radio section is not operating.Type: GrantFiled: April 22, 2005Date of Patent: June 2, 2009Assignee: NEC CorporationInventor: Hidetoshi Takenaka

Patent number: 6411829Abstract: Radio communication equipment is provided which is capable of reliably completing a charge of a battery at a proper charging capacity and without causing deterioration of the battery regardless of whether or not a backlight function is continuously used at the time of charging. When a portable telephone starts charging, a CPU judges whether the backlight is turned ON. If the backlight is turned ON, a signal indicating that it is in the ON state is outputted from the CPU to a charging completion detecting circuit. The charging completion detecting circuit sets a threshold value indicating a charging completion current value to a threshold value being higher than an ordinary threshold value. A current detecting circuit detects a value of a current flowing from a charging terminal to a charging current detecting resistor and the charging completion detecting circuit judges whether a current value detected by the current detecting circuit has reached the set threshold value.Type: GrantFiled: February 24, 2000Date of Patent: June 25, 2002Assignee: NEC CorporationInventor: Hidetoshi Takenaka

Patent number: 5400341Abstract: In a control device for controlling a CPU 11 in accordance with an input voltage which is applied to the CPU and which results from a power source voltage, a first detecting circuit 16 produces a first detection signal when the power source voltage is lower than a first voltage. Responsive to the first detection signal, a switching circuit 21 stops supply of the input voltage to the CPU and the CPU assumes to a waiting state. A condenser 15 discharges an electric voltage in order to compensate a drop of the input voltage. When the input voltage is lower than a second voltage which is lower than the first voltage, a second detecting circuit 17 produces a second detection signal to make the CPU become a reset or an initial state.Type: GrantFiled: April 1, 1993Date of Patent: March 21, 1995Assignee: NEC CorporationInventors: Masayuki Makino, Hidetoshi Takenaka

Patent number: 5105458Abstract: In a mobile telephone system, a base station establishes a radio link to a mobile station and a connection to a swtiched telephone network when the mobile station is in communication with a network-side station. The base station constantly monitors signals from the mobile station over the radio link. If it detects that the radio link is failing during a communication, an announcement is transmitted to the network-side station. A recording/playback apparatus is then operated to record a message from the network-side station. The base station further includes a ringing detector for detecting a ringing signal from the network when an incoming call is received from a network station. A connection is then established between the calling station and the base station if it fails to access the mobile station. An announcement is then transmitted to the network and the recording/playback apparatus is operated to record a message from the calling station.Type: GrantFiled: August 7, 1990Date of Patent: April 14, 1992Assignee: NEC CorporationInventor: Hidetoshi Takenaka
