  • Publication number: 20040251934
    Abstract: A capacitor charging circuit and method including a plurality of serially connected capacitors and parallel monitor circuits connected in parallel on a one-to-one basis to the capacitors. Each one of parallel monitor circuits applies a direct-current source voltage to a capacitor and bypasses a charge current of the capacitor when the charge voltage of the capacitor exceeds a reference voltage. Each of the parallel monitor circuits includes a reference voltage circuit, a voltage detecting circuit, a comparator, a bypass switching circuit, and a voltage limiter. The reference voltage circuit generates the reference voltage. The voltage detecting circuit detects the charge voltage of the capacitor. The comparator compares the reference voltage with an output voltage from the voltage detecting circuit and controls the bypass switching circuit to bypass the charge voltage using the voltage limiter to limit a voltage applied to the bypass switching circuit.

  • Patent number: 6812673
    Abstract: A charge/discharge protection apparatus of the present invention includes a switch provided on a charge/discharge current line, the charge/discharge current line being connected to a secondary battery of a battery pack. A charge-state overcurrent detector outputs a control signal when a charge-state overcurrent condition of the battery is detected in a charge state of the battery pack. A control unit sets the switch in OFF state to cut off connection between the charge/discharge current line and the battery in response to the control signal output by the charge-state overcurrent detector. The charge/discharge protection apparatus has a capability to detect the charge-state overcurrent condition of the battery, and protects the secondary battery from being damaged due to the charge-state overcurrent condition.

  • Patent number: 6768289
    Abstract: A charge/discharge protection circuit prevents a charge control FET from being overheated or ignited so as to improve safety by preventing an oscillating operation of the charge control FET, which is connected to a charge path of a secondary battery in series so as to cut off a charge current. A discharge control FET is connected to the charge path in series so as to cut off a discharge current from the secondary battery. A latch circuit latches an overcharge detection signal output from an overcharge detection circuit and outputs a signal so as to control the charge control FET. A delay circuit delays the discharge over-current detection signal and supplies the delayed discharge over-current detection signal to the discharge control FET. A reset circuit resets the latch circuit so as to turn on the charge control FET when a discharge over-current is detected and an overcharge is not detected.

  • Patent number: 6643028
    Abstract: In this invention, a digital copying machine to be connected to a network feeds originals in each document unit for each sheet by use of an ADF to read the images of the originals and prints the read images in each document unit for each page in a printing form selected by the user. Therefore, a plurality of original images read in each document unit can be effectively confirmed in accordance with the purpose of the user on the spot where the reading operation is effected. Further, the actual concentration can be adjusted while observing reduced images on the confirmation sheet and inputting of an actual image and inputting for correction can be easily attained. In a case where a specified page among a plurality of originals is scanned again, all of the originals are set on the original table of the ADF without extracting the specified page from the originals and the specified page can be scanned again. Therefore, the pages of the originals can be kept in order.
