Title: Magnetic recording and reproducing device
Inventor: MASUI HIKARI
IPC: H04N9/86
Filed: 1983-06-15
Abstract: PURPOSE:To eliminate beat disturbance due to crosstalk component by changing a center frquency of an angular modulating circuit at each unit period to allow an unnecessary component in a reproduced line sequential chrominance signal to enter a blocking band of a comb line filter. CONSTITUTION:The frequency of the beat component at the center carrier is f-f', where (f) is the center carrier frequency of the angular modulation line sequential chrominance signal recorded on a prescribed track and f' is that of an adjacent track. The said frequency is selected to a frequency corresponding to a trough of the characteristic of the comb line filter 28. Thus, the carrier frequency of the angular modulating circuit 10 in the recording system is made different by the frequency at the trough of the filter 28 every time a track is formed on a magentic tape 18. As a result, the frequency offset is applied to the angular modulation line sequential chrominance signal between adjacent tracks and the beat component is eliminated by the filter 28 of the reproducing system.

Title: Air conditioning device for automobile
Inventor: YOKOYA SATORU
IPC: B60H1/00
Filed: 1987-04-30
Abstract: PURPOSE:To perform comfortable air conditioning even during abnormal working of a mix damper, by a method wherein, during detection of abnormality of the mix damper, a deviation between the preset position of the mix damper and a target position is determined, and when the deviation is high, the number of revolutions of a blower motor is gradually reduced. CONSTITUTION:A mix damper abnormality detecting part 9 receives a mix damper control signal from a control part 3 to a mix damper drive device 8. Simultaneously, a rotation signal output from a mix damper 6 to the mix damper drive device 8 is monitored, and when no rotation signal is outputted even after lapse of a time longer than a time required for movement to a target position, an abnormal signal from the mix damper 6 is outputted to an abnormality processing part 10. The abnormality processing part 10 inputs a present position from a mix damper position detecting device 7 to determine a deviation between the present position and a target position. When the deviation is low, a blower motor is run at the target number of revolutions, and when the deviation is high, the number of revolutions is gradually decreased. This constitution enables execution of optimum control even during abnormal working.
