Title: Channel selection method of television receiver
Inventor: OGUCHI TOMIHIRO
IPC: H03J7/02
Filed: 1984-05-10
Abstract: PURPOSE:To accelerate a channel selecting action by confirming the presence of a station detecting signal after detecting the down signal only in a search mode and then the center signal or the up signal. CONSTITUTION:A VCO4 scans the local oscillation frequency by the output of a control circuit 11 during a period when the down signals are detected from an end to the other end of a prescribed set range successively by steps of the prescribed frequency width. The circuit 11 sets the local oscillation frequency sets the local oscillation frequency at a level obtained by adding an offset frequency corresponding to a channel plan to the local oscillation frequency on the channel plan only in case a down signal is not detected first by an AFT wave detecting circuit 8 through the above-mentioned scan. Then the scan is carried out to detect the presence or absence of both the center and up signals through a station detecting signal generating circuit 10 when no down signal is detected any more. Then the circuit 10 detects the presence or absence of a station detecting signal SD when the center or up signal is detected. In this case, the fine tuning is carried out. This can accelerate a channel selecting action.

A compressor is started in these starting conditions, it is operated for the decided continuity time at the decided starting rotational frequency, and after the continuity time, it is corrected to a target starting rotation number to start a normal rotational frequency control loop. Even in the case of liquid is stored in low pressure side pipings during operation stoppage, danger of damaging by compression of the liquid can be avoided.  When the outer air temperature at the time of starting heating operation is over the specified temperature TamS, limitation to the starting rotational frequency can be released, thereby rise of heating can be speedy.
