  • Patent number: 8947025
    Abstract: A regeneration control device of an electrically powered vehicle includes a motor generator which performs electric power regeneration by braking a driving wheel of the electrically powered vehicle, and a battery to which electric power regenerated by the motor generator is supplied. A monitoring unit includes at least one of a charging rate detection unit configured to detect a charging rate of the battery and a voltage value detection unit configured to detect a voltage value of the battery. A control unit controls the electric power regeneration of the motor generator according to at least one of the charging rate and the voltage value of the battery detected by the monitoring unit. The control unit is configured to decrease regenerative electric current of the motor generator as at least one of the charging rate and the voltage value is increased.

  • Patent number: 5349164
    Abstract: An automatic cooking appliance has a magnetron to cook the food. The cooking appliance has a dial, which is rotatable and capable of being pressed, on an operation panel thereof. A cooking mode in the menu is selected due to the rotation of the dial. The cooking mode is determined by pressing of the dial. The cooking appliance controls the magnetron in accordance with the determined cooking mode. This enables the dial to be used for multiple purposes to thereby save space on a control panel.
