Title: Clock recovery circuit
Inventor: KAWAHARA NOBUHIRO
IPC: H04N19/85
Filed: 1986-07-08
Abstract: PURPOSE:To recover an accurate clock even when an inexpensive and low accurate oscillator is used resetting an input voltage of the oscillator when an oscillated frequency exceeds a prescribed range thereby resetting the oscillated frequency and setting the frequency range of a recovered clock independently of the characteristic of the oscillator. CONSTITUTION:A difference circuit 1, based on information (a) relating to a clock frequency at the sending side inputted at each prescribed period and information (b) relating to a recovered clock (c) outputted from a counter 5 at each prescribed period, obtains a frequency difference between the clock of the sender side and the recovered clock. An integration circuit 2 applies digital integration to an output of the difference circuit 1 and the result is inputted to a D/A converter 3. An oscillator 4 is oscillated at a frequency in response to the output voltage of the converter 3 and outputs the recovered clock (c). A frequency divider 6 frequency-divides a transmission clock (d) and outputs a signal representing a prescribed period of the clock (d). The counter 5 counts number of recovered clocks (c) while receiving a signal from the frequency divider 6 and outputs a count (e). A frequency range detection circuit 7 discriminates whether or not the frequency of the recovered clock (c) is within a predetermined range from the count (e) and resets the integration circuit 2 when the frequency is at the outside of the range.

Abstract: PROBLEM TO BE SOLVED: To perform a quick braking in a controlled state by providing a pressure bias regulating integrator for regulating a wheel speed error signal showing the difference between a wheel speed signal and a reference speed signal, in reply to a brake pressure signal. SOLUTION: A speed comparator 18 compares a wheel speed signal, with a reference speed signal and generates a wheel speed error signal Vs showing the difference between the both. This speed error signal Vs is regulated by a pressure bias regulating means (PBM) integrator 20, a transitional control means 20, and a compensating network 24, and totaled by a total connector 26 to form an anti-skid control signal 28. The PBM integrator 20 is initialized with the feedback value of braking pressure when the wheel gets close to a skid level, or at the moment the slip speed Vs is larger than a previously set limit. Thus, the PBM integrator 20 can be precisely initialized by the braking pressure at the initial skid, and a quick reply can be performed. Thus, the control function in a quick braking can be ensured.

Abstract: PURPOSE: To improve the accuracy and to shorten the rolling time, by operating on the basis of information, etc., previously inputted to the automatic deceleration controller, in order to previously once slow down and to finally decelerate at the moment detecting the tail end.  
     CONSTITUTION: The position just under the first stand 5 is taken as the point of completing the deceleration of the tail end of the coil; after detecting the tail end of the coil with the tail end detector 9, the deceleration command signal 14 is given to the rolling mill, on the basis of information on the coil side and the mill side, etc.; and the automatic deceleration controller 10 previously operates to judge whether the deceleration of the mill is in good time or not. As the result of this operation, if the deceleration is learned to be too late, the controller 10 operates the degree of previous deceleration to a speed proper for making the following deceleration to be in good time. When the residual amount of the coil 2 on the inlet side becomes less than the specified value, the speed is once slowed down to above stated speed. And according to the signal from the tail end detector 9, the final deceleration is given to the mill. According to this method, the accuracy is greatly improved, and overall rolling time can be effectively shortened.
