  • Publication number: 20110241611
    Abstract: Provided is a battery charging technique by which high efficiency of the battery charging can be always controlled no matter how the power consumption of the battery is changed. In a battery charger, a charging control circuit holds a charge/non-charge state of a battery during an arbitrary period of time in order to prevent the unbalance of phase voltages due to occurrence of transition between the charge/non-charge states during a short period of time and the reduction of the efficiency of the battery charging. Further, zero-crossing erroneous detection in a phase voltage of the output of a three-phase alternating-current generator due to noises is prevented.

  • Publication number: 20110241610
    Abstract: There is provided a battery charging technique by which various battery charging control can be achieved even when power consumption of a battery is small. In a battery charger, in order not to turn OFF a power switch even when an ACG starting detection circuit recognizes that an output of a generator is not generated in a state in which the power consumption of the battery is small and the voltage of the battery is not dropping, a voltage of the battery in addition to phase terminal signals of a three-phase alternating-current generator is inputted to the ACG starting detection circuit, and the ACG starting detection circuit controls not to turn OFF the power switch when the output of the three-phase alternating-current generator is generated or when the voltage of the battery is equal to or higher than a predetermined voltage.

  • Patent number: 5677707
    Abstract: An image display apparatus, which is used to display a plurality of images on one display image by carrying out a filtering operation, comprises a memory unit, a filter unit, a write control unit, a delay unit, and a switching unit. The write control unit controls the writing of the display data at a region having a specific address length between adjacent display-regions, when storing the display data into the memory unit. The filter unit applies a filtering operation to the display data read out from the memory unit along the display scanning direction, and the delay unit gives a different delay value to the display data output from the filter unit. The switching unit switches the display data having a different delay value output from the delay unit at a boundary line of the adjacent display-regions. Therefore, the length between the adjacent display-regions can be shortened, and an image having a preferable length between the adjacent display-regions without an intervention can be displayed.
