Title: Rotary magnetic field detector
Inventor: SHIKITA YUKIHISA
IPC: G01R33/06
Filed: 1984-10-12
Abstract: PURPOSE:To eliminate changes in the detection sensitivity due to variations in the temperature, by connecting each one end of two magnetic resistance elements arranged at angles shifted properly to a common potential while the other end thereof connected to independent constant current sources to detect the potential difference. CONSTITUTION:Two magnetic resistance elements MR1 and MR2 are built on the surface of a substrate 4 in a zigzag pattern in such a manner as to be at the right angle to each other along the length of the zigzag pattern. A circular magnet 6 magnetized diametrically is fastened at the upper end of a rotating shaft 5 to generate a magnetic field turning within the surface of the substrate 4 as the shaft 5 rotates and the electric resistances of the elements MR1 and MR2 change according to the angle of the rotary magnetic field. Then, respective one ends of the elements MR1 and MR2 are connected to the ground GND of a common terminal while constant current sources 7 and 8 are connected to respective other ends thereof to run constant currents I1 and I2. The constant currents I1 and I2 are so set that the voltage drops of the elements equal when the angle of the magnetic field theta=45 deg.. So, when the difference in the terminal voltage between both the elements is detected with a comparator 3, the resulting value is free from the temperature as it contains no portion corresponding to changes in the temperature of the resistance value according to a specified formula.
