Title: Magnetic recording and reproducing device
Inventor: KITAZAWA KENICHI
IPC: H04N5/93
Filed: 1989-01-31
Abstract: PURPOSE:To decrease the noises and to eliminate the skews occurring at the upper part of a screen in a special reproduction state by using a means which moves the position of a video head at reproduction, a means which exchanges the vertical synchronous signal part of a reproduced video signal at special reproduction, and a means which cancels the exchange of the synchronous signal part. CONSTITUTION:When a normal reproduction state is changed to a speed search state, an exchange vertical synchronous signal generating circuit 52 produces an exchange vertical synchronous signal which is exchanged with a video signal via a vertical synchronous signal exchange circuit 51. Then the tape speed is fixed and heads 5 and 5' are mechanically displaced based on an envelope detection signal. Then the exchange of the vertical synchronous signal is cancelled when the coincidence is secured between the head locus and the recording track on a magnetic tape 13 and a reproduced vertical synchronous signal is acquired. As a result, the clear pictures are obtained with no noise and at the same time the screen blurring due to the vertical step-out is eliminated on a monitor at special reproduction.

Filed: 1984-02-10
Abstract: PURPOSE:To secure the actuation of a PNPN switch with high dv/dt tolerance and high sensitivity by using an element of PNPN structure to drive a short circuit protecting TR which gives a short circuit to a P-N junction at one side of the PNPN switch. CONSTITUTION:When the transient voltage having a sudden rise is applied between an anode A and a cathode K, the drive current of a short-circuiting TRQ1 is supplied from a place equivalent to a cathode gate through a PNPN element 2. Thus the TRQ1 is driven with the characteristics similar to the stored residual charge produced by the composite TR effect of a PNPTR and an NPNTR in a PNPN switch 1. Thus the dv/dt effect protecting capacity. While the element 2 is short-circuited by the P-N junction of the anode A and an anode gate GA to a DC action and turned off. Therefore the TRQ1 is not actuated either. Then the gate ignition sensitivity and the minimum holding current of the switch 1 are decided by a resistance R. The resistance of such a level that prevents the misignition due to the leakage current of the switch 1 is needed to the R. Therefore the high ignition sensitivity is obtained from the gate.

Filed: 1988-02-03
Abstract: PURPOSE:To improve the accuracy of a control position by using both an absolute encoder and an incremental encoder for executing a position control of a motor and controlling a position and a speed by a feedback signal from the incremental encoder. CONSTITUTION:Both an absolute encoder 4 and an incremental encoder 5 are used and by a position feedback signal from the incremental encoder 5, a position control and a speed control are executed. Accordingly, by eliminating a waste time of a control system, the responsiveness is maintained, and also, whether a stop position where the position control has been executed is within an allowable range or not is judged based on an output signal from the absolute encoder 4 as a reference. If said position exceeds the allowable range, setting of a coordinate position is updated by an absolute position signal from the absolute encoder 4. In such a way, the accuracy of a control position can be improved.
