Title: Tsuyoshi Takegami: Innovator in Electron-Emitting Technologies
Introduction
Tsuyoshi Takegami is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electron-emitting devices, holding a total of 11 patents. His work focuses on improving image display technologies and methods for fabricating electron-emitting devices.
Latest Patents
One of his latest patents is for an image display apparatus. This apparatus includes a rear plate with electron-emitting devices, each comprising a pair of electrodes and an electron-emitting unit. The design features first wirings that interconnect electrodes in one of the pairs of electrodes, and second wirings that interconnect electrodes in the other pair, which have higher resistance than the first wirings. An insulating layer covers the second wirings, and resistive films are connected to the first wirings, partially overlapping with the second wirings. The resistive films have a surface resistance set to 10Ω/□ or more.
Another notable patent involves a method of fabricating an electron-emitting device that incorporates a conductive film containing first and second particles with different resistance values. This method aims to create a gap that provides excellent electron-emitting properties efficiently and with low electric power. The process involves flowing a current in the electroconductive film, where the ratio of first particles is maintained between 2% and 30%, and the resistance ratio between the first and second particles is between 5 and 1000.
