Latest Patents

Kumasaka's latest patents include a beam recording method and device. This recording device features a beam deflection section that allows for the relative movement of an irradiation position of an exposure beam on a substrate with a resist layer. Additionally, it includes a substrate velocity adjustment section that modifies the moving velocity of the substrate based on the deflection amount of the exposure beam. A deflection control section is also present, which adjusts the deflection velocity of the exposure beam during the exposure of recording signals according to the substrate's moving velocity.

Another significant patent is the thread-type electron emission element. This invention utilizes a cathode substrate as a cathode, applying voltage to both the cathode and anode. The electron emission element emits electrons from an electron source on the cathode substrate, directing them onto an electron irradiation surface on the anode. The thread-type electron source allows for a simplified configuration, as it eliminates the need to move the electron irradiation surface or the electron source. This design not only simplifies the apparatus but also maintains a constant size of the beam spot at the irradiation position.
