Title: Automatic termination circuit
Inventor: SUMIYA HIROYASU
IPC: H04L25/02
Filed: 1986-09-18
Abstract: PURPOSE:To prevent the deterioration of components such as transistors (TRs) used for an output circuit by using a detection signal of a peak value detection signal so as to apply resistance termination to the output of an output section automatically when the other end of a transmission line connected to the output section is opened and releasing the resistance termination when a device is connected to the other end of the transmission line through the control. CONSTITUTION:In the output circuit where an output section 1 sending an output signal to a transmission line is provided with a peak value detection circuit 2, a large attenuation, e.g., 4dB is used to attain good output matching to an attenuator ATT 9' connected to the secondary side of a transformer 8. Then, the output of the secondary side of the transformer 8 is branched and fed to the circuit 2, and the detection signal is fed to a Schmitt trigger circuit 11. Then a relay driver 12 is controlled by the output signal of the Schmitt trigger circuit 11 to apply resistance termination to the output section when the transmission line is opened. In connecting a device through a resistor including a reactive component to the open end of the line, the circuit 2 controls to release the termination of the said output section. Thus, the deterioration of TRs used for the transmitter is prevented while keeping the output matching.

Title: Magnetic disk device detecting and compensating defect of servo signal
Inventor: SATO MASAHIKO
IPC: G11B21/10
Filed: 1991-08-30
Abstract: PURPOSE:To distinguish an erroneous position signal from head position deviation by obtaining an invariable regardless of positional deviation of a head from first and second position signals and recognizing a defect of a servo signal at the time when this invariable is not within a set range. CONSTITUTION:An invariable calculating means 13 takes in the first position signal indicating the displacement from the center position of a track reproduced from a magnetic disk and the second position signal indicating the displacement from the boundary position of the track. The sum of respective absolute values is calculated to obtain the invariable regardless of positional deviation of the head. If the invariable is not within the set range, a discriminating means 12 recognizes error of a position signal due to a defect and ignores this position signal and uses the preceding sampled position signal to perform the following-up control. If the error of position signals is detected, the write inhibiting operation is suppressed through an inhibition suppressing means 14 to avoid serious trouble.
