Title: Signal separator
Inventor: MORII IKUO
IPC: G11B27/19
Filed: 1979-09-20
Abstract: PURPOSE: To make it possible to separate a signal securely even at a random tape speed and to secure stability by performing signal separation regardless of the reproduction speed of a magnetically recorded tape, without using any band-pass filter.  
     CONSTITUTION: A clock signal from counting clock signal generator 8 is frequency- divided by four at frequency separating circuit 9 and then counted by counter 10 before being stored in memory 13. This is compared to the count value of counter 12 counting the one-third frequency-division output of frequency dividing circuit 11 and the result is stored in the 1st flip-flop 15. The output of AND between the output of differentiating circuit 6 and that of circuit 15 is sent to output terminal 17. The output of differentiating circuit 6 and the inversion output of flip-flop 15 are AND-ed to set the 2nd flip-flop 19. The inversion output of this flip-flop 19 and an output to terminal 17 are AND-ed to exercise write control over memory 13.

Title: Load current control system
Inventor: ISHIDA KOUICHI
IPC: G05F1/10
Filed: 1984-06-13
Abstract: PURPOSE:To miniaturize an element and to ensure control with high follow-up performance by feeding back a capacitor current of an LC filter as well as the value obtained by applying the feedback gain to the actual voltage/current value to the output of a controller. CONSTITUTION:A proportion element 12 which detects and amplifies the current flowing through a capacitor C constituting an LC filter 2 is provided together with a proportion element 13 which detects and amplifies the actual value of the load voltage and a proportion element 11 which detects and amplifies the actual value of the load current. In such constitution, the amplified outputs of both elements 12 and 13 are added to the control output of a voltage controller 6A in the direction of polarity where each amplified output is negatively fed back as well as to the control output of a current controllers 5A in the polarity direction where the amplified output of the element 11 is negatively fed back. Thus a desired ripple attenuation amount is secured without using a large-capacity LC. Furthermore, the control is possible with high follow-up performance despite a change of the set value.
