Abstract: PURPOSE:To control driver's own vehicle speed to gently approach or keep away from the preceding vehicle without going across a distance between both vehicles by controlling the vehicle speed so that the relative speed to the preceding car is below a predetermined value and controlling a between-car distance type feed-back to maintain the distance between vehicles when a desired distance between both vehicles is reached and a switch is operated. CONSTITUTION:Signals of a distance between vehicles by a radar unit 7, a vehicle speed setting switch 19 and a between-vehicle distance setting switch 20 are inputted to a control unit 4. The control unit 4 reads the actual distance L between vehicles and the relative speed V1 of driver's own vehicle to the prededing one detected by the radar unit 7. When driver's own vehicle is approaching the preceding vehicle, the relative speed V1 is made less than a predetermined value Va and lower than that of the vehicle before the approach and decelerated to the vehicle speed higher than the vehicle speed of the preceding one. Also when the vehicle is keeping away from the preceding vehicle, it is accelerated with the relative speed V1 being lower than the predetermined value Va. And between vehicle type feed back control for controlling the vehicle speed by setting the distance between vehicles to a desired one when a between-vehicle distance setting switch is turned on is carried on.

Abstract: PURPOSE:To improve the operating efficiency by releasing a call to a first specified story of an other elevator when a call to a second specified story is registered in one cage earlier reached the first specified story out of the cages in which calls are simultaneously registered on the first specified story. CONSTITUTION:A specified story to which calls are to be simultaneously registered is set to plural elevators (two elevators A, B in the figure) controlled and operated separately by different control devices. For example, when a first story is a specified story, and either an up-button 1A or 1B is depressed at the first story, valls are simultaneously registered 2A, 2B to the two elevators A, B, and the two elevators A, B approach the first story.

Filed: 1987-12-21
Abstract: PURPOSE:To suppress twitching in a perpendicular direction of the reproducing picture of a still picture and simultaneously to keep interlace normally at the time of performing ordinary reproduction or receiving an ordinary television signal by detecting whether a signal connected to a television receiver is a still picture signal or the ordinary television signal, and changing the frequency division ratio of a frequency divider based on the detection signal.
