  • Publication number: 20030103250
    Abstract: When image data read by a scanner apparatus is to be transferred to and displayed by a simplified portable terminal, the capability such as the size or color depth of an image display area may be lower than that of the scanned image data. If this is the case, the terminal transfers its capability to the scanner apparatus, and the scanner apparatus converts the scanned image data into image data matching the capability of the terminal. The obtained image data is transmitted to and displayed by the terminal. This obviates the need for a user to set complicated parameters on the scanner apparatus. This can also reduce the load of image processing performed by the terminal on image data transmitted from the scanner apparatus.

  • Patent number: 6563292
    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: 6501248
    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: 6389227
    Abstract: A lens-fitted film unit and production thereof, wherein lens-fitted film unit has a front cover, a rear cover, a main body and a magazine chamber lid to take out a film magazine from a film magazine chamber located in the main body, below the film magazine chamber and at the bottom surface of the lens-fitted film unit. The front cover, rear cover and main body have respectively a rib, and the surrounding of the lower portion of the film magazine chamber is surrounded by the rib of the front cover, the rib of the rear cover and the rib of the main body. After the rear cover is attached, the film magazine chamber lid is attached so that the magazine chamber lid is fixed to the front and rear cover and is not fixed to the main body.

  • Patent number: 6316915
    Abstract: A charge/discharge protection circuit of the present invention includes a first terminal to which a negative electrode of a charger is connected and an internal detector unit which has an input connected to the first terminal, and prevents the variation of the threshold voltage of the input transistors in a short-circuit detector unit and in an overcurrent detector unit when the improper charger is connected to the battery for a long time. An improper charger detector unit outputs a detection signal when an improper charger is connected to the battery pack, in response to a voltage supplied to the first terminal by the improper charger.

  • Patent number: 6144248
    Abstract: A reference voltage generating circuit generates a reference voltage having a flat temperature characteristic over a practical temperature range. In a reference voltage transistor pair, a depletion N-channel field effect transistor and an enhancement N-channel field effect transistor are connected in series between a first voltage source and a second voltage source so that the reference voltage is output from a juncture between a gate of the depletion N-channel field effect transistor and a gate of the enhancement N-channel field effect transistor. A temperature characteristic correction circuit is provided to at least one of the depletion N-channel field effect transistor and the enhancement N-channel field effect transistor. The temperature characteristic correction circuit changes temperature sensitivity of the reference voltage by changing an effective gate size of the one of the depletion N-channel field effect transistor and the enhancement N-channel field effect transistor.
