    摘要： Disclosed is a battery charger that can be connected in series to a power feed line, which lies between an external power source and an electric/electronic device, and that monitors the power consumption state of the electric/electronic device and begins and halts the charging of a battery in consonance with the power consumption state. Since a battery charger according to the present invention can be inserted in series into a power feed line that lies between an AC/DC adaptor and an electric/electronic device, the wiring arrangement is not complicated and a spare battery can be automatically charged. Since the charging is performed only during a period in which power consumption by the electric/electronic device is relatively low, the charging operation does not affect the system operation. As the battery charger does not require AC to DC conversion circuit, it is compact and light and is suitable for use along with a portable device. Further, when the spare battery pack is carried with being attached into the battery charger, the volume is not great, and as the terminal portions of the battery are covered and are protected from coming into contact with foreign conductive material, the possibility that the electrodes of the battery will be short-circuited can be prevented. To use a notebook computer while staying at a hotel on a business trip, a user need merely connect in series an AC/DC adaptor, a Travel Quick Charger, and a notebook computer in the named order via a power supply cord. The spare battery can be attached into a Travel Quick Charger while being carried to the destination.

    摘要： Disclosed is an electronic apparatus which includes a power supply unit and a constant voltage rechargeable battery. The power supply unit activates a dedicated charging circuit, which is located near the battery, only at the charging end stage after the terminal voltage of the battery has attained a predetermined value, and provides constant voltage control for a charge current by using the charging circuit. The charging circuit, however, is not employed at the initial charging stage, where precise constant voltage control is not required. The output current, for which constant current control is performed by the AC adaptor, is employed unchanged as a charge current, with which quick charging is performed. That is, since a transformer in the charging circuit is not activated at the initial charging stage, a power loss, which accompanies the operation of the transformer, and heat generation and the occurrence of magnetic noise in the electronic apparatus can be reduced to a minimum.

    摘要： A user 100 makes an inquiry through a billing institution 103 to a gene analyzing institution 104 retaining gene analysis information, and the billing institution 103 transfers the gene analysis information received from the gene analyzing institution 104 to the user 100 using a routing address that was dynamically set. The gene analysis information is encrypted at the gene analyzing institution 104 in such a way that decryption at the billing institution 103 is infeasible. Since the gene analyzing institution 104 cannot identify the user 100, and the billing institution 103 cannot know the content of the gene analysis information, privacy of the user 100 can thus be protected.
