With a total of 3 patents, Inoue's work has advanced the technology used in various electronic applications.

Latest Patents

One of Inoue's latest patents is a field emission cathode designed to ensure uniform electron emission from each emitter. This innovation prevents line defects even when the gate electrode is electrically short-circuited with an emitter. The movement of electrons in a channel formed on the channel forming electrode is controlled by applying a positive voltage to the current control electrode. This allows for precise control of the current supplied from the cathode electrode to the emitter. In cases where the emitter is short-circuited with the gate electrode, the increased current density can destroy the channel, but Inoue's design allows for the current supply to the emitter to be stopped effectively.

Another significant patent is a process for manufacturing a transparent conductive film wiring board. This process simplifies manufacturing by utilizing a dry procedure, which reduces costs. The method begins with a SiO₂ layer on a substrate, followed by the formation of a black ITO film. The black ITO film is then processed using a laser, cutting it into a predetermined wiring pattern. The metal evaporated during this process is collected by a vacuum suction head, and the substrate undergoes calcination to oxidize and crystallize the black ITO film, resulting in a transparent ITO film of the wiring pattern.
