Patent number: 7345477Abstract: In a magnetic detection device for obtaining an output from between a variable resistance element using the magnetoresistance effect and a reference resistance element, a balance between resistance values in the device can be easily adjusted in a wide range. A voltage is applied to a resistance adjusting unit, a reference resistance element, and a variable resistance element, which are serially connected, and is also applied to another variable resistance element, another reference resistance element, and another resistance adjusting unit, which are serially connected. When subjected to a magnetic field of a predetermined size, resistance values of the variable resistance elements change, and as a result, the potentials of output terminals change. Each of the resistance adjusting units includes serially connected parallel portions each including a plurality of parallel connected resistance elements.Type: GrantFiled: February 26, 2007Date of Patent: March 18, 2008Assignee: Alps Electric Co., Ltd.Inventors: Hideto Ando, Kiyoshi Sato, Hiroyuki Nakada
