Latest Patents

Nakai's latest patents include a "Magnetron unit with a magnetic field compensating means." This invention features a magnetic flux path for magnetic flux supplied from a permanent magnet to the interaction space. A magnetic member is strategically placed outside the anode cylinder to provide a by-path for the magnetic flux. This magnetic member is composed of a magnetic compensating alloy, which has a unique property of decreasing magnetic permeability with an increase in temperature.

Another notable patent is the "Magnetron with continuous magnetic circuit." This design incorporates a cylindrical anode and a coaxially positioned cathode. It also includes an output portion extending from the anode and an annular magnet. A magnetic shim plate is integrated between the permanent magnet and the yoke, ensuring that the entire surface of the permanent magnet maintains magnetic contact with the yoke. This configuration forms a continuous magnetic circuit, effectively preventing any gaps that could lead to fluctuations or reductions in magnetic flux.
