Patent KR-20010030430-A (KR)
Inventor: DOI TAKASHI
IPC: F25D21/08
Filed: 2000-09-19
Abstract: PURPOSE: To prevent a hot refrigerant from flowing in an evaporator for a freezing chamber in case that a compressor stops, in an object which is so constituted as to alternately perform the R mode to cool a cold storage chamber by means of an evaporator for cold storage chamber and the F mode to cool a freezing chamber by means of an evaporator for freezing chamber. CONSTITUTION: The stop of a compressor 24 accompanying the temperature drop in the storage is performed in R mode. In the R mode, a change-over valve 26 is in the condition of an arrow A, and a compressor 24 and an evaporator 20 for freezing chamber are blocked. In case that the user stops the compressor 24 in this condition, the hot refrigerant from the high pressure side never flows in the evaporator 20 for freezing chamber, and besides a check valve 29 on outlet side of the evaporator 20 for freezing chamber gets to work, so there is no reverse flow from the evaporator 15 for cold storage chamber to the side of the evaporator 20 for freezing chamber, either.

Title: internet based telephone service method
Inventor: JI MIN GU
IPC: H04L29/06
Filed: 2000-10-05
Abstract: PURPOSE: A telephone service method using the Internet is provided to enable a user to use an identification code, a country code, and an area code, composed of numbers only, in the case of attempting a telephone call using an Internet telephone service system. CONSTITUTION: If a call request signal is generated(S1), a management server searches for an IP address in order to recognize the kind of the originating terminal(S2). In case that an identification code exists at the head of the sent telephone number(S3), the management server forms a speech path to an Internet phone or a computer from a wire telephone or a mobile phone(S4). If it is judged that "@" exists at the head instead of the identification code, the management server recognizes the call request from an Internet phone or a computer to another Internet phone or computer and judges whether it is an international call or a domestic call(S5). If a country code follows after the character "@", the management server recognizes it as an international call and forms a speech path to an overseas Internet phone or computer from an Internet phone or a computer(S6,S8). However, if a country code is not detected after the detection of the character "@", the management server recognizes it as a domestic call and forms a speech path from a domestic Internet phone or computer to another domestic Internet phone or computer(S6,S7).

Abstract: PURPOSE: A protection circuit of an inverter for an LCD(Liquid Crystal Display) back light is provided to protect a piezoelectric trans and an inverter by stopping the driving of the inverter when an LCD lamp is opened. CONSTITUTION: An electric power supply unit(1) supplies a voltage to a system. A control IC(Integrated Circuit)(2) generates a frequency corresponding to the voltage supplied from the electric power supply unit(1). A driving unit converts a DC(Direct Current) voltage inputted from the control IC(2) into an AC(Alternate Current) voltage, eliminates a high-frequency signal of the AC voltage, and generates an AC high voltage. An LCD lamp(6) is turned on in response to the AC high voltage from the driving unit. A feedback unit(7) detects a lamp current flowing the LCD lamp(6) and converts the detected lamp current into a DC voltage to input it to the control IC(2). An AC signal detecting unit(100) selectively outputs the voltage from the electric power supply unit(1) in response to the magnitude of the AC voltage applied through the LCD lamp(6). An adder(200) adds the voltage from the AC detecting unit(100) and a dimming voltage from the external to output the added voltage.
