Title: Noise eliminator
Inventor: IWASAKI EIJI
IPC: H04N5/21
Filed: 1986-06-10
Abstract: PURPOSE:To eliminate noise even at the part of a moving image, by detecting the part of the moving image between frames, after dividing into two or more frequency band areas, and generating an individual correction signal by every frequency band area, using a bit of detected information. CONSTITUTION:A frame differential signal E is band-limited at a band-pass filter 71, then being changed to a signal E1. The signal E1 is sent to a multiplier 91, and a motion detector 81. At the motion detector 81, an appropriate factor K1 is decided corresponding to the size of the band limited frame differential signal E1, and it is sent to the multiplier 91. In this way, the correction signals to an input television signal are generated at frequency band areas different with each other. Not only the noise is eliminated from a high correlative part between the frames, in other words, a still image in an input television signal X, but the noise is eliminated from a frequency component having a low rate of change out of signals changed between the frames, similarly as a case in the still image.

Filed: 1986-06-10
Abstract: PURPOSE:To enable an automatic change-over of four-way valve to be performed by a method wherein an operation of a compressor is performed when output voltages of the first to third comparators satisfy a condition of an exclusive NOR, and then the four-way valve is held at a heating operation cycle when an output from the third comparator is in an H level. CONSTITUTION:An actual turned-ON condition of a compressor is attained when outputs from the first, second and third comparators 34, 36 and 38 satisfy an exclusive NOR. At first, a heating resistor (a first set temperature) is set by a variable resistor 21 and a cooling set value (a second set temperature) is set by a variable resistor 20, respectively. At this time, the third set temperature is automatically set by a resistor 31 in such a way as it is always higher than the first set temperature by about 1 deg.C. Then, a four-way valve 2 is not changed over to a heating operation side (shown by a rigid line) unless the room temperature is less than the third set temperature at an intermediate period. Therefore, by adjusting the first set temperature, a changing-over temperature of cooling or heating operation is varied and coping with a changing-over of a cooling or a heating operation during the intermediate period is enabled.
