摘要： A shock sensor detects shocks from all directions in a plane. A coil produces a magnetic field. A magnetic fluid is sealed in a closed container located in the magnetic field. A magnetoresistive effect element is also is located in the magnetic field and opposes the magnetic fluid. The magnetic fluid moves relative to the magnetoresistive effect element when the magnetic fluid receives a shock. When the magnetoresistive effect element is subjected to a change in magnetic field, the resistance of the magnetoresistive effect element changes. The magnetoresistive effect element may be formed of four elements in a bridge configuration and the output of the bridge is processed in an output circuit. The output circuit outputs a sensor output when the magnetic fluid moves relative to the magnetoresistive effect element.

摘要： In the microscope, an optical path and optical path of an image forming system are set so as to be perpendicular to each other when viewed from the top. In other words, in this microscope, there exists an ocular optical system that guides light, which propagates the optical path to optical path of the image forming system, to a user. The optical path is formed in a direction perpendicular to a direction of the light from a sample emitted from the ocular optical system to the user.
