  • Patent number: 11028943
    Abstract: A control butterfly valve comprises a valve body having a fluid passage through which a fluid flows, a valve disc controlling an opening and closing of the fluid passage of the valve body, and a diffuser including a passing hole configured to allow the fluid, which passes through the valve disc, to pass therethrough and a passing part configured to allow the fluid, which passes through the valve disc at a low speed, to pass therethrough.
    Type: Grant
    Filed: April 8, 2019

  • Patent number: 9812201
    Abstract: A method for operating an electronic device including a variable resistance element comprises performing a reset operation on the variable resistance element. The variable resistance element is fully reset by a first reset voltage applied thereto. The performing of the reset operation includes applying a second reset voltage to the variable resistance element, the second reset voltage having a magnitude smaller than that of the first reset voltage, determining whether the variable resistance element is mildly reset or not, and applying a third reset voltage to the variable resistance element when it is determined that the variable resistance element is mildly reset, or terminating the reset operation when it is determined that the variable resistance element is fully reset, the third reset voltage having a magnitude smaller than that of the first reset voltage.
