Patent JP-S59104720-A (JP)
Title: Thin film magnetic head
Inventor: NOMURA NOBORU
IPC: G11B5/39
Filed: 1982-12-07
Abstract: PURPOSE:To eliminate the effect of external noises by biasing the magnetization of a magneto-resistance effect element to a fixed direction and supplying the current from terminals at both sides of the magneto-resistance effect element to extract the reproduction output voltage and to ground a middle point terminal in terms of AC. CONSTITUTION:A middle point terminal 32 is grounded via a capacitor 35 although the voltage of the terminal 32 varies in terms of DC owing to the asymmetry of power supplies 36 and 37 or an MR element 31. Thus the external noises are grounded through the terminal 32. The asymmetry of the element 31 does not produce a big problem with noises since the resistance of the element 31 is much smaller than the internal resistance of power supplies 36 and 37. For the reproduced signal component, the direction of an MR current (i) is reverse to the element 32 and the outputs have phases opposite to each other between terminals 33 and 34. Then a reproduced signal is obtained at an output terminal 39 of a differential amplifier 38 with no offset if the differential amplification is given to said output. The effect of external noises can be substantially eliminated from the reproduced signal.

Title: Minute displacement measuring equipment and its method
Inventor: TAKATSU ICHIRO
IPC: G02B6/00
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To provide minute displacement measuring equipment wherein precise optical adjustment, light phase adjustment, highly precise adjustment of the initial position of an object to be measured, complicated synchronous measurement, etc., are unnecessary, operation is simple, and miniaturization and cost reduction are enabled. SOLUTION: A light entering an optical fiber 30 from a laser oscillator 40 propagates in a rectilinear optical waveguide 12, and a part of the light is reflected on account of difference of refractive index. The light entering the waveguide 12 is cast on an object 80 to be measured from the end portion where an antireflection film 18 is formed, and the reflected light again enters the waveguide 12. An interference light of this reflected light and the light which was reflected by the end face enters a photodetector 50. On the basis of its intensity, the displacement of the object 80 is detected by a displacement detecting part 70. In the initial state that the object is not displaced, an electric field is applied to the waveguide 12 via an electrode 15, and the phase difference between the two lights which form the interference light is set to be π/2.  Thereby the sensitivity of interference light intensity to the displacement is made maximum.
