    Abstract: PROBLEM TO BE SOLVED: To enable efficient charging of a secondary battery. SOLUTION: A charging current controller 11 selectively inputs power from a first external power source 16 or a second external power source 18 and outputs a part of the power to a charger 22 for charging a battery 23. A reference value supplying means gives a first reference value which corresponds to the capacity of the first source 16, when the charging controller 11 is connected to the first source 16 and gives a second reference value which corresponds to the capacity of the second source 18, when the charging controller 11 is connected to the second source 18. A current detector 13 detects a current, which the charging controller 11 receives from the first source 16 or a second source 18. A charging current control circuit 15 controls the charging current of the charger 22, so as not to exceed the first or second reference value detected by the current detector 13.

    Abstract: PROBLEM TO BE SOLVED: To provide a power supply unit having an internal AC adaptor on which an exterior AC adaptor is also mounted and portable electronic equipment. SOLUTION: Each DC output of an exterior AC adaptor 10 and an internal AC adapter 20 is transmitted to a DC/DC converter 30 through its own output line. A power supply switching circuit 50 which performs connection/interruption is arranged on the output line on the exterior AC converter. The adaptor 20 includes an AC power supply input detecting means which notifies an electronic equipment body side whether the adaptor 20 itself has an external AC input and asserts a detection signal when the external AC input exists. In the electronic equipment, the circuit 50 interrupts the output line on the exterior AC adaptor side in response to it. On the other hand, when the external AC input does not exist; a detection signal is negated and the output line on the exterior AC adaptor side is connected in response to it.

    Abstract: PROBLEM TO BE SOLVED: To detect a wireless access point from a mobile computer such as a note PC, a PDA and the like without using a special device for detecting access points. SOLUTION: The card for wireless network communication includes an access point detecting circuit which detects wireless access points via a wireless antenna. The access point detecting circuit is provided with an electric power inflow path which supplies electric power in response to a request for access point detection from a user, when the power of a device is off or suspended to which the card for wireless network communication is attached. The card for communication allows the access point detecting circuit to operate in response to power supply from the electric power inflow path. When the access point detecting circuit detects a wireless access point in response to the instruction, access point detection signals are transmitted to a detection indicator or a detection voice output device. In this way, wireless access points can be detected without starting up the above device. COPYRIGHT: (C)2006,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To obtain a method which controls the discharging operation and the charging operation of a plurality of secondary batteries and in which the batteries can be charged in a short time and with good efficiency. SOLUTION: When a discharging operation is started, a plurality of secondary batteries are parallel-discharged without fail (Step 11). Consequently, all of the plurality of secondary batteries at the start of a charging operation have free capacities. By the free capacities, the parallel charging operation of the plurality of secondary batteries is realized without fail. As a result, the plurality of secondary batteries can he charged in a short time and with good efficiency.
