Title: Tsuneo Ihara: Innovator in Photonics
Introduction
Tsuneo Ihara is a prominent inventor based in Hamamatsu, Japan. He has made significant contributions to the field of photonics, particularly in the development of photocathodes and electron tubes. With a total of 2 patents, his work has had a substantial impact on various applications in imaging technology.
Latest Patents
Ihara's latest patents include innovative designs for a photocathode and an electron tube. The photocathode and electron tube feature a unique design that allows the photocathode plate to be securely fixed without the use of adhesives. This design is particularly advantageous in environments that require high vibration resistance or experience thermal stress due to significant temperature variations. The photocathode plate is sandwiched between a faceplate and a support plate, with first pins embedded in the faceplate joined to the support plate. This construction enables the photocathode plate to be securely fixed to the faceplate.
Another notable patent involves a photoemitter that utilizes a junction, such as a Schottky junction, formed between a conductive electrode and a semiconductor. A bias voltage is applied between the conductive electrode and an outward-emission-side electrode on the semiconductor. When illuminated, photoelectrons are emitted from the conductive electrode into the semiconductor, transported through it, and emitted from the semiconductor surface, which has been treated to reduce the surface barrier height. This design enhances the efficiency of the photoemission process.
