With a total of four patents to his name, Uchiyama's work focuses on enhancing the efficiency and safety of electronic devices through innovative design and engineering solutions.
Latest Patents
Uchiyama’s latest patents focus on advanced electron tube designs. The first patent describes an electron tube with a unique envelope that features a glass bulb body constructed from both upper and lower hemispheres, connecting to a cylindrical glass bulb base. This design incorporates a photocathode on the inner surface, allowing for efficient electron emission when light interacts with the photocathode. Furthermore, an avalanche photodiode (APD) is strategically positioned to improve electron detection.
His second recent patent expands on this technology with an electron tube that includes an insulating tube inside the envelope. One end of this tube connects to the envelope, while the other supports an avalanche photodiode. By applying ground voltage to the envelope and a positive high voltage to the APD, the design maximizes safety and simplifies handling by keeping the positive voltage away from the envelope, all while effectively amplifying and detecting photoelectrons.
