Filed: 1990-08-11
Abstract: PURPOSE:To detect a focus even when an object is out of a range finding area, etc., by detecting the focus by executing zooming to a wide side in the case that the focus cannot be detected caused by low contrast scanning. CONSTITUTION:When a focus detection start switch is turned on, the focus is detected by a range-finding part 2.

Abstract: PURPOSE:To make it possible to correctly detect a defrosting starting time and a defrosting terminating time by detecting the temperature of a coolant and the indoor temperature and controlling the defrosting operation based on the temperature difference between both temperatures. CONSTITUTION:The set time of a timer circuit 11 is a time until the temperature of a coolant discharge pipeline assumes a stable condition. When the timer circuit 11 terminates timing, a temperature control circuit 9 starts its operation. When a difference between the temperature signal of an indoor temperature detecting element 6 and that of a coolant discharge pipeline temperature detecting element 7 reaches a set value, a signal is emitted, and a defrosting control relay 10 switches a four-way valve 2 to start the defrosting operation. The completion of defrosting is detected by the temperature signal of the temperature detecting element 7, and a signal is emitted from the control circuit 9 to the control relay 10 and the four-way valve 2 is switched to terminate the defrosting operation, and the air conditioner returns to the space heating operation. Upon this occasion, the timer circuit 11 receives the signal and is reset by the control relay 11, and the operation is restarted. As a result, there is no possibility of any erroneous action being carried out, and a correct defrosting starting time and a correct defrosting terminating time can be detected.
