  • Pedal device
    Patent number: 8466359
    Abstract: A pedal device includes a pedal chassis 9 provided in a pedal case 8, a pedal 10 that moves by rotating in the up-down direction with respect to the pedal chassis 9, and a rotation holding mechanism 11 that holds the back portion of the pedal 10 to the pedal chassis 9 such that the back portion of the pedal 10 is movable in the up-down direction. Therefore, when the pedal 10 is depressed, the back portion of the pedal 10 is moved downward by the rotation holding mechanism 11, according to the rotational movement of the pedal 10.
    Type: Grant

  • Method for treating ETA-containing wastewater
    Patent number: 7081194
    Abstract: ETA-containing wastewater discarded from a regenerator of a nuclear power plant with a pressurized water reactor is neutralized with sodium hydroxide to adjust the pH value, metals are precipitated and separated, the wastewater is thereafter supplied to a filtration apparatus and filtered, and then supplied to an electrolyzer to conduct electrolysis and reduce the COD value induced by ETA to below the environmental discharge limit standard value.
