Latest Patents

One of Oyama's latest inventions is a Hall effect sensing apparatus for moving objects. This apparatus features a moving magnetic member with concave and convex segments at its periphery. It includes a detector with a pair of Hall effect elements that convert magnetic signals into electric signals. The processing circuit processes these signals, while a magnet provides the necessary magnetic field. A yoke, which is movably arranged, adjusts the detecting sensitivity of the apparatus, ensuring optimal performance despite variances in magnetic characteristics.

Another notable invention is a movable magnet type pump. This pump consists of a magnet moving body with at least one axially magnetized permanent magnet and a liquid passage. The design allows the magnet moving body to slide within a liquid introducing chamber. A series of coils are fixed around the chamber, and the interaction between the current applied to these coils and the magnetic flux from the moving body causes it to reciprocate, effectively pumping liquid.
