Patent number: 6208117Abstract: When a power supply activating signal is inputted from an input terminal by depressing a main power supply switch of an electronic apparatus, electric power is supplied from a battery to a protection circuit portion and a management circuit portion through a pack power supply control circuit. Thus, the self discharge of the battery is reduced when a battery pack is not used. The protection circuit portion is operative to output a detection signal to the management circuit portion. Further, the management circuit portion posts a state of the battery to the electronic apparatus. The protection circuit portion is not controlled by the management circuit portion. Thus, even when a bug or a runaway occurs in MCU circuit of the management circuit portion, the battery can be safely protected.Type: GrantFiled: March 29, 2000Date of Patent: March 27, 2001Assignee: Fujitsu LimitedInventor: Michio Hibi

Patent number: 4772950Abstract: A method and apparatus for sampling and processing a video signal having a time base fluctuation with sampling clock pulses produced from an oscillator which is instantaneously phase-synchronized with synchronizing information of the video signal. The synchronizing information is separated from the video signal by a separator and the oscillator is controlled to at least one of start and stop oscillation in accordance with the synchronizing information.Type: GrantFiled: October 5, 1984Date of Patent: September 20, 1988Assignee: Hitachi, Ltd.Inventors: Takashi Furuhata, Hitoaki Owashi, Michio Hibi

Patent number: 4746996Abstract: A skew error correction device for a video signal in a television receiver or the like is disclosed. An oscillator produces an oscillation output signal of a constant frequency which is phase-synchronized with horizontal synchronization information included in an input video signal, and the output signal is used as a write clock. In a vertical blanking period, the oscillation output signal or a frequency-divided signal thereof is phase-compared with an output of a reference signal generator of a predetermined frequency or a frequency-divided signal thereof, and a phase error signal is negatively fed back to voltage control means which voltage-controls the oscillation frequency of the oscillator. Thus, the oscillation frequency is stabilized without using an AFC circuit and a skew error in the input video signal is eliminated.Type: GrantFiled: June 26, 1985Date of Patent: May 24, 1988Assignee: Hitachi, Ltd.Inventors: Takashi Furuhata, Hitoaki Owashi, Michio Hibi
