    摘要： The disclosed magnetic immunoassay device, which performs magnetic immunoassays using antigen-antibody reactions, can perform speedy immunoassays without bound/free separation in the test samples. The device is also practical, being capable of stable magnetism measurement without magnetic shielding. The disclosed magnetic immunoassay device is provided with: an excitation coil that uses an AC magnetic field to magnetize a test sample containing a magnetic marker; a magnetism sensor that measures magnetism in the test sample and outputs a magnetism signal; and a displacement sensor for detecting changes in the distance between the test sample and the magnetism sensor. By optimally setting the bandwidth of a lock-in amplifier, which detects changes in the phase of the magnetism signal outputted by the magnetism sensor, and the rotational speed produced by a drive system, which moves the test sample at low speeds, the impact of environment magnetic noise is reduced, and correcting the magnetism signal using distance information obtained from the displacement sensor allows stable magnetism measurement.

    摘要： For measuring hardness of an object, a measurement apparatus is pushed against the object and a degree of hardness calculation system calculates hardness based on information from the measurement apparatus. The measurement apparatus includes an acceleration sensor which outputs first information of acceleration of a contact area of the measurement apparatus, and a second sensor, such as a magnetic sensor or a pressure sensor, which outputs second information based on pressure applied to the contact area. The degree of hardness calculation system generates a second-derivative waveform by twice differentiating a waveform based on the output of the second sensor, compares the second-derivative waveform and the information of acceleration from the acceleration sensor, and calculates hardness of the object based on the comparison result.

    摘要： There is provided a biomagnetic field measurement apparatus capable of carrying out exact positioning work and highly sensitive signal detection. To bring a sensor surface close to a body surface while the sensor surface and the body surface are kept parallel, a cryostat is constructed so as to be capable of oscillating and expanding and contracting. A gantry is formed by three supports. A first support is a portal support that supports the whole of the gantry. A second support is supported on the first support, and is rotatable with a first direction being the axis. A third support is supported on the second support, and is movable in the axial direction of the cryostat as viewed from the second support. The cryostat is supported on the third support, and moves integrally with the third support.
