  • Patent number: 9099931
    Abstract: A power supply device includes a converter, a rectifier circuit, a voltage cycle detection circuit, and a power supply cutoff signal output unit. The converter converts an AC voltage inputted from an external power supply to a DC voltage and outputs the DC voltage. The rectifier circuit rectifies the AC voltage inputted from the external power supply and outputs a rectified waveform voltage. The voltage cycle detection circuit detects a voltage cycle in which the rectified waveform voltage reaches a predetermined threshold value and, when the voltage cycle is detected to be longer than a predetermined cycle, outputs a voltage cycle abnormality signal. The power supply cutoff signal output unit outputs a power supply cutoff signal when the voltage cycle abnormality signal is inputted.

  • Patent number: 8189356
    Abstract: There is provided a PWM inverter capable of preventing a phase error from occurring in generating a PWM signal even in the case where a carrier wave frequency is not sufficiently higher than a signal wave frequency. A PWM signal generating section (2) includes a phase adjusting section (11) configured to advance a phase of the signal wave by adding, to a signal wave, a delay component of the PWM signal with respect to the signal wave, the phase delay component being involved by digital control. Furthermore, in a case where the carrier wave frequency is changed, the phase delay component with respect to the signal wave is updated in synchronism with the timing of change of the carrier wave frequency.

  • Patent number: 7830206
    Abstract: An extraction circuit is connected to an input path of an output amplifier. When the power is turned on, the extraction circuit extracts current on the basis of a difference between the normal rise of the supply voltage and a delayed supply voltage. Therefore, a steep rise in the input of the output amplifier when the power is turned on can be removed.

  • Publication number: 20100210360
    Abstract: When a player character performs an act tendency (boom) triggering act, the act number counters are updated for each non-player character associated with the boom triggering act. The value of each act number counter is periodically added to an act tendency value for each non-player character. After an act tendency value reaches an upper limit, the corresponding non-player character performs an act in response to the act tendency triggering act performed by the player character. The act of each non-player character is changed in accordance with the acts performed by the player character in the game world, which provides the player with a fresh feeling that the act performed by the player character set a trend in the game world.
