Title: Pulse shaping circuit
Inventor: NAGASAWA TAKAFUMI
IPC: H03K5/04
Filed: 1985-05-16
Abstract: PURPOSE:To prevent fluctuation of pulse width due to the quantization error of a counter by using a flip-flop circuit so as to convert a pulse train comprising plural pulses having different pulse widths into a pulse train of pulses having nearly constant ulse width. CONSTITUTION:When a pulse is fed to the input terminal 1, the 1st flip-flop circuit 3 is set in response to the leading and a counter 5 starts counting. When the count of the counter 5 reaches the 1st prescribed value and the input pulse is lost, the 2nd flip-flop circuit 9 is not set. When the 2nd flip-flop circuit 9 is set and the count of the counter 5 reaches the 2nd prescribed value, the 1st flip-flop circuit 3 is reset and a prescribed width of output signal is obtained at an output terminal 13. Thus, even when a narrow width pulse is inputted as the input pulse, or a pulse with a wide pulse width is given, an output pulse having a nearly constant pulse width is obtained.

Abstract: PURPOSE:To improve running performance of an carrying vehicle and to contribute for beautification of working place by providing a cleaning, brush contactable with rail over the entire width of vehicle in front of running wheels and dust absorbing magnets in the rear with predetermined interval. CONSTITUTION:When cutting powder or dust 13 is scattered on a floor face 12, almost of them is cleaned off by means of a cleaning brush 6 mounted at the front, while when cutting powder which is most troublesome for a position detecting sensor leaks to the rear, it is absorbed from the floor face 12 by means of a permanent magnet 7 so as to prevent flow out of the cutting powder to the position detecting sensor arranged on the center line of running wheels. Since the permanent magnet 7 can be mounted in single touch, cutting powder adhered to the magnet can be cleaned easily. Consequently, position detecting sensor does not function erroneously and running performance of unmanned running vehicle is improved considerably, while furthermore the running route is cleaned at all times resulting in beautification of working place.
