With an impressive portfolio of three patents, he continues to push the boundaries of innovation, significantly impacting technology with his work.
Latest Patents
Hisafumi Imura's latest innovations include two pivotal patents. The first is a *measuring/inspecting apparatus and measuring/inspecting method* designed to enhance blanking control of electron beams. This technique addresses the challenge of settling time delays caused by ringing in the blanking control signal. By implementing a main blanking unit alongside a correction blanking control unit, Imura's invention facilitates high-speed switching control of the electron beam. This system synchronizes correction signals in real time with the switching of the main blanking control signal, effectively cancelling out the ringing and thereby reducing the settling time.
The second patent involves an *address drive circuit and plasma display apparatus*. This innovation focuses on achieving high impedance within an address drive circuit to minimize the number of recovery switches required while maintaining power recovery efficiency. By creating this high impedance during the sustain period of a plasma display panel, Imura's invention cancels capacitance coupling between the X and Y electrodes and their respective address electrodes, simplifying the power recovery circuit without compromising efficiency.
