Title: Video exchanging device
Inventor: IKEDA YASUNARI
IPC: H04M3/00
Filed: 1987-06-30
Abstract: PURPOSE:To prevent a beat disturbance from being generated due to mutual modulation between carrier signals on a television picture, by separating a video signal and the carrier signal and allowing them separately to pass through switching circuit. CONSTITUTION:A multiple signal is separated into a video signal SV and carrier signals SA, SD by a low-pass filter 2011 and a high-pass filter 2031, respectively and inputted to first and second switching circuits 202 and 204. Subsequently, the video signal SV obtained from the first switching circuit 202 and the carrier signals SA, SD obtained through a band pass filter 2071 from an output signal of the second switching circuit 204 are synthesized and outputted. By the band pass filter 2071, a spurious signal SSP in a band of the video signal SV generated due to the mutual modulation between the carrier signals in the second switching circuit 204 is eliminated, and no spurious signal SSP is contained in the band of the video signal to be outputted. In such a way, beat disturbance due to the mutual modulation between the carrier signals generated on a television picture can be prevented.

Abstract: PURPOSE:To improve follow-up ability to a preceding vehicle by adding a relative speed to conditions of a brake applying action and taking-off action for quick braking operation and performing the brake taking-off action if vehicle-to- vehicle distance conditions are not satisfied during distance increase. CONSTITUTION:Signals from a vehicle-to-vehicle distance radar 1, a speed sensor 2 and switches 3, 7, 8 are input to an input port 4a in a controller 4, computed by a ROM 4c in which a control program is stored, a RAM 4d and a CPU 4b and output from an output port 4e. The controller 4 finds a relative speed between a preceding vehicle and one's own vehicle and a vehicle-to-vehicle distance deviation, and when the relative speed is below a threshold value and the vehicle-to-vehicle distance deviation is over a threshold value a plural threshold values are provided there. An auxiliary brake and a main brake are operated in sequence corresponding to these threshold values and given different hysteresises to perform a brake taking-off action in adverse sequence. In this way, the change of the auxiliary brake and the main brake in brake applying and taking-off timing allows safe control excellent in follow-up ability.
