    摘要： A leakage blocking device of a valve is disclosed. When a fluid flowing in a flow path 11 leaks through a gap between the outer circumferential surface of a valve stem bottom (21) and a bottom guide hole (31), a plug 53 of a piston 50 is pushed into a sealing oil chamber 45 by a pressure P1 of the leaked fluid acting on a bottom pressure acting surface S1 of the piston and pressurizes a sealing oil L in the sealing oil chamber 45 to a pressure P2 higher than the pressure P1 of the leaked fluid, thereby blocking leakage of fluid of the valve.

    摘要： A fuse circuit includes a fuse driving unit, a separation/connection unit, a voltage equalization unit, and a latching unit. The fuse driving unit is configured to drive an output terminal in response to a fuse reset signal, depending on data programmed in a fuse. The separation/connection unit is disposed between the fuse and the output terminal and configured to separate or connect the fuse from or to the output terminal in response to a control signal. The voltage equalization unit is configured to equalize both ends of the fuse to the same voltage in response to the control signal. The latching unit is configured to latch and output the output terminal driven by the fuse driving unit.
