  • Phase-locked loop and delay-locked loop
    Patent number: 10516400
    Abstract: Disclosed is a phase-locked loop and a delay-locked loop. When the phase-locked loop switches from a sleep state to an active state, a frequency of a reference signal is the same as a frequency of a reference signal which has been synchronized in a previous active state. The phase-locked loop alternately operates in a sleep state and an active state. A frequency-divided output signal of the phase-locked loop is synchronized with a frequency-divided reference signal, when the phase-locked loop switches from a sleep state to an active state, a frequency of the frequency-divided output signal is identical to a frequency of a frequency-divided output signal which has been synchronized in a previous active state. Information corresponding to the frequency of the frequency-divided output signal which has been synchronized in the previous active state is stored in a capacitor.

  • HEAT PUMP SYSTEM FOR PRODUCING STEAM BY USING RECUPERATOR
    Publication number: 20190323704
    Abstract: In the present invention, a recuperator is used in a refrigerant cycle to make a heat exchange between a refrigerant generated in a condenser and a refrigerant before flowing into a compressor, thereby supercooling the refrigerant to minimize the quality of the refrigerant introduced into an evaporator, elevating temperatures at an inlet and an outlet of the compressor, and increasing condensed heat of the condenser. In the present invention, a recuperator is used to increase condensed heat of the condenser, leading to increasing the heat which circulation water circulating in a steam producing cycle receives from the condenser, whereby steam production efficiency can be improved.
