  • Apparatus for manufacturing hydrogen-containing water
    Patent number: 11584666
    Abstract: An apparatus for manufacturing hydrogen-containing water is disclosed. In one aspect, the apparatus includes a container part formed with a upper space and a lower space positioned vertically from each other around a connecting passage therein. The apparatus also includes an ion exchange membrane configured to close the connecting passage and an electrolytic part comprising a cathode disposed on the upper space and a cathode an anode disposed on the lower space. The apparatus further includes a handle part configured to couple to the container part and to provide a supply passage for water to be supplied to the lower space and a discharge passage to discharge oxygen and ozone generated from the lower space.
    Type: Grant
    Filed: May 16, 2017
    Date of Patent: February 21, 2023
    Assignee: Welltech Korea Co., Ltd.
    Inventors: Seung Yeol Park, Nam Suck Lee, Pil Jong Kim

  • Data output buffer
    Patent number: 5675170
    Abstract: A data output buffer is disclosed. Generation of a latch-up is prevented by forming a N-well guard ring to interrupt the movement of minority carriers injected from the drain of NMOS transistor to the N.sup.+ pickup region of PMOS transistor. Accordingly, reliability of the device is improved.
