Latest Patents

Yokoyama's latest patents include innovative designs that improve vacuum technology. One of his notable inventions is a vacuum envelope that can enhance the vacuum degree in a field emission device. This vacuum envelope features a cathode side substrate with field emission elements and an anode substrate, which are spaced apart in the electron emission direction. The design incorporates at least two openings that allow for the removal of residual gas by introducing a high-temperature gas into the envelope for a specified duration. Following this process, one opening is sealed while the envelope is evacuated through the remaining openings.

Another significant patent is for an envelope designed for vacuum electronic devices. This invention allows for the sealing of a fluorescent display device while maintaining a high vacuum without the need for an evacuation hole at the electrode formation section of the substrate. The cathode substrate is formed with a large plate-like shape that includes a field emission cathode, while the anode substrate is arranged oppositely to the cathode substrate. This design effectively prevents damage and contamination of the substrates during the sealing process.
