Abstract: Disclosed are an air conditioning system with two compressors so as to shorten standby time for re-operating a stopped compressor and variably change the compression capacity of a refrigerant according to cooling load, and a method for operating the air conditioning system. The method for operating the air conditioning system with two compressors, comprises the first step of simultaneously operating the compressors regardless of cooling load at an early stage of the operation, the second step of selectively operating one of the compressors according to the cooling load, and the third step of additionally re-operating the stopped compressor when the operated compressor selected from the compressor in the second step is continuously operated for longer than a designated time, thereby shortening the standby time for re-operating the stopped compressor, rapidly changing the compression capacity of the refrigerant according to the cooling load, and improving users' comfort within a room.

Abstract: Disclosed is an apparatus for and method of stabilizing a picture in an image system during the changing of a broadcast channel. Since channel altering causes noise in synchronization, and an unstable picture when performing automatic frequency tuning (AFT) and automatic gain control (AGC), an image signal of the previous channel is stored in an image memory before being changed, and output onto the screen using a switch controlled by a microcomputer during the unstable period for AFT and AGC, instead of the image signal of the altered channel. The image signal of the altered channel is output after the output of an automatic controlled is stabilized.

Abstract: A circuit for recording video signals includes: a luminance signal processor for separating a luminance signal from a video signal and frequency modulating the separated luminance signal; a chrominance signal processor, including a color detector, for separating a chrominance signal from a video signal, and amplitude modulating the chrominance signal so as to be distributed in a low frequency band when the chrominance signal is detected by the color detector; a mixer for mixing an output of said luminance signal processor and an output of the luminance signal processor; a recording device for recording an output of the mixer on a record medium; and a frequency characteristic controller for controlling a frequency band of an output of the luminance signal processor corresponding to whether the video signal is a black-and-white signal or a chrominance signal, the frequency characteristic controller being connected between the mixer 40 and the luminance signal processor.

Abstract: A synchronizing detecting circuit removing video and audio noises by discriminating the non-broadcasting channels from the broadcasting channels. The synchronizing detecting circuit has a first inspector for recognizing signals based on the number of pulses of the gated pulse rows supplied from a gate device during the synchronized pulse period of the received synchronizing signal, a second inspector for recognizing the synchronizing signal by inspecting the number of pulses of the gated pulse rows from the gate device during the period of the synchronized width of the synchronizing signal supplied in accordance with the output of the first inspector, and an output stabilizer for outputting synchronism detecting signals of a stabilized logic state by stabilizing the outputs of the second inspector.
