  • Patent number: 6979978
    Abstract: A charge control device has a full charge detection circuit for checking whether a secondary cell is in a fully charged state or not based on the charge voltage and/or the charge current of the secondary cell, a control circuit for controlling the feeding of electric power to the secondary cell according to the output of the full charge detection circuit, a storage circuit for storing control information, and a setting circuit for setting the level of the charge voltage and/or the charge current at which the full charge detection circuit recognizes the fully charged state according to the control information read from the storage circuit. The control information is fed into the storage circuit from outside. With this configuration, it is possible to accurately control the charging of a secondary cell by canceling the influence of stress occurring when an IC is packaged or mounted on a circuit board and other factors.

  • Patent number: 6842123
    Abstract: A switch assembly (1) comprises a push-button section (52) and a push-button body (53) as an operation transmitting member, an LED box (54) and a contact-making contact (56) as a direct functioning member, and a communication-function incorporating contact (communications contact) (55) as an information input/output functioning member, as permitting these components to be connected with each other. Therefore, the switch assembly can respond to an operation given to the push-button body (52) by causing the contact-making contact (56) to provide an output for switching between a conductive state and a non-conductive state and by causing the communications contact (55) to output an information signal to a network.

    Abstract: In an automatic gain control (AGC) circuit for controlling a preceding gain control unit and a following gain control unit, the AGC circuit according to the present invention includes at least a comparison unit, a first gain control signal output unit and a second gain control signal output unit. The comparison unit compares a signal level from the following gain control unit with a reference value. The first gain control signal output unit outputs a first gain control signal to the following gain control unit in response to an output signal obtained as a result of comparison in the comparison unit. The second gain control signal output unit outputs a second gain control signal to the preceding gain control unit. Further, the second gain control signal has a time constant longer than that of the first gain control signal output unit, in response to the output signal obtained as the result of comparison in the comparison unit.
