摘要： PROBLEM TO BE SOLVED: To prevent the measurement from being affected by the induced voltage between the signal lines connecting the probe and the resistance measurement circuit by improving the resistance measurement technique in the strong magnetic field.
SOLUTION: The probe 2 is in contact with a work 1 of a measurement object, sends signal to a resistance measurement circuit 6, and measures the electric resistance of the work. A magnet 7 moves parallel in X-axis direction for changing the magnetic field intensity impressed on the work 1, and rotates around the X-axis by 180° for inverting the direction of the magnetic field impressed on the objective work 1. For making an A signal line 4 or a B signal line 5 generate no induced voltage, even if the magnet 7 moves in the X-axis direction, the signal lines are oppositely faced in the Z-axis direction (i.e. in the magnetic field direction) while being separated. Because of no magnetic field line passing through between the two signal lines 4 and 5, even the magnet 7 moves between the arrow marks a to c, no induced voltage is generated. Moreover, an arm 10 is constituted of a resin material, no eddy current is induced.

摘要翻译：要解决的问题：通过改善强磁场中的电阻测量技术，防止测量受连接探针和电阻测量电路的信号线之间的感应电压的影响。
解决方案：探头2与测量对象的工件1接触，将信号发送到电阻测量电路6，并测量工件的电阻。磁体7在X轴方向上平行移动，以改变施加在工件1上的磁场强度，并且围绕X轴旋转180°以反转施加在物体工件1上的磁场的方向。为了制造信号线4或B信号线5即使磁体7在X轴方向上移动也不产生感应电压，信号线在Z轴方向（即磁场方向）上相反地面对，同时分离。由于两条信号线4和5之间没有通过磁场线，所以即使磁体7也在箭头a至c之间移动，也不产生感应电压。此外，臂10由树脂材料构成，不产生涡流。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem that there is a method of using the magnetic property of a magnetoresistive element as an object of the standard of an actual magnetic head slider but it is too vulnerable to static electricity to use as a source of the standard over a long term. SOLUTION: When initially setting up a tester 500, the preamplifier 514 of a magnetic property measuring device 502 is connected to an emulator 1 to input signals emulating the resistance and resistance change of the magnetoresistive element to use as the standard. The output of the preamplifier 514 is A/D converted to input to an MPU 510 and changed into resistance in the MPU 510 to store in the ROM518. The tester compares the resistance of the measured magnetoresistive element with the resistance stored in the ROM using it as the standard. Since the standard thus setup changes over aging, it is periodically checked and adjusted by connecting the tester to the emulator. COPYRIGHT: (C)2008,JPO&INPIT
