Latest Patents

Matsuoka's latest patents include innovative designs for an electron tube, an electron tube module, and an optical device. The electron tube features a vacuum container with a light transmitting substrate, a photocathode on the inner surface, an anode, and a prism. The prism is designed with a bottom surface bonded to the light transmitting substrate, a light incident surface, and a light reflecting surface that further reflects light incident to the photocathode. This design allows light to re-enter the photocathode, enhancing its efficiency. The light reflecting surface has an outwardly convex curved shape, while the light incident surface is strategically located within an imaginary spherical surface along the light reflecting surface.

The electron tube module comprises the electron tube and a casing. The casing includes a ceiling wall with an opening, and the second surface of the prism is parallel to this ceiling wall. This design ensures that part of the second surface is exposed to the outside through the opening, facilitating better light interaction.
