Abstract: PURPOSE:To facilitate regulation of the output timing of pulse signal by regulating the resistance of a variable resistor arranged between predetermined input terminal and output terminal of a Hall element arranged on a stator with respect to a rotary position detecting magnet fixed to the rotor. CONSTITUTION:A plurality of armature coils 5 are arranged annularly thus constituting a state 1. A Hall element 13 is arranged on a stator 1 corresponding to a rotary position detecting magnet 12 fixed at the outside of a cup-shaped yoke 8 fixed to a rotary shaft 7. The Hall element 13 is provided with a pair of input terminals 13a, 13b and a pair of output terminals 13c, 13d and variable resistor 17 is connected between the terminals 13a, 13b. AC voltage produced between the terminals 13c, 13d corresponding to the field linked with the Hall element is fed to a comparator 14. A mono-stable multivibrator 15 produces a pulse having a predetermined time width when the comparator 14 produces an output. Output point of the comparator 14 is adjusted through adjustment of the variable resistor 17. By such arrangement, an easily adjustable reference position detector is constituted where fine positional adjustment of Hole element is not required.

IPC: G01N33/553
Filed: 1989-12-21
Abstract: PURPOSE:To make it possible to automate the entire process of indirect agglutination simply by using magnetic particles or particles containing magnetic material as a carrier, and forcibly settling the carrier to the bottom part of a container by using magnetic force. CONSTITUTION:Magnetic particles or particles containing magnetic material are used as reagent, and an immunity measuring system comprising indirect agglutination is constituted. After the reaction, the component containing the particles is forcibly settled to the bottom of a container with magnetic force. Then, the container is inclined, and the presence or absence of the immunity reaction is judged based on the releasing state of the settled particles from the container. When the component containing the magnetic particles or the particles containing the magnetic material are forcibly settled with the magnetic force, an electromagnet or a permanent magnet can be used. The magnetic particles are forcibly settled on a settling accelerating stage using the magnet and attracted to the bottom surface of the container. The same action as the settlement using a centrifugal method can be obtained. Thus, the measurement can be carried out in a short time with no influence of variation or the like.
