Title: Phase difference detector
Inventor: YANAGAWA KOUICHI
IPC: G01R25/00
Filed: 1980-12-09
Abstract: PURPOSE:To perform the digital display of a phase difference between two signals having the same frequency with simple constitution by using a dual slope type analog/digital converter which uses the same reference voltage source in common for a charging voltage source and a discharging voltage source. CONSTITUTION:Two input signals having the same frequency are applied to terminals 14 and 16 and then supplied to a phase difference detector 22. A phase difference theta between those two input signals is converted into signals (c) and (d) by a detector 22 to control the connections of changeover switches 24 and 32. Only while the signal (c) is at a high level, the output signal (e) of the switch 24 is at +EsV and the output signal (f) of the switch 32 is at 0V, so that an integrator 12 integrates the +EsV signal when the signal (c) is at the high level. Then, a zero potential is applied to the integrator 12 and the uninverted input terminal of an operational amplifier 30 rises up to +EsV, so that the output (g) of the integrator 12 rises by +EsV. The voltage V0 of this signal (g) is expressed by V0=Es(T2-T1)N/CR, where C is the capacity of a capacitor 38 and R is the resistance value of a resistor 28 and when N(T2-T1)=T0, T0=NT(1- theta/pi), calculating the phase difference theta.

Filed: 1984-08-22
Abstract: PURPOSE:To attain accurately and easily pad position adjustment to narrow as less as possible the contact range between a head and a medium by adjusting the position of the pad made of a magnetic material so that the inductance viewed from the coil end of a magnetic head is maximized. CONSTITUTION:In flowing a current to a coil 3 of the magnetic head 4, a closed magnetic path 7 including the pad 5 made of the magnetic material is formed. Thus, the inductance viewed between both ends 3a, 3b of the coil 3 depends on the position of the pad 5 and when the pad is at an optimum position, the inductance is maximized. In adjusting the pad position so as to maximize the inductance, the relative position between the magnetic head 4 and the pad 5 is in optimum state. In setting a magnetic recording medium 1 between the head 4 and the pad 5, the clearance between the gap 2a of the head 4 and the recording medium 1 is narrowest. Thus, the optimum position of the pad 5 is set accurately and easily via an L-meter 8.
