Title: Yoichi Kobori: Innovator in Fluorescent Technology
Introduction
Yoichi Kobori is a prominent inventor based in Mobara, Japan. He has made significant contributions to the field of fluorescent technology, holding a total of 13 patents. His work focuses on improving the efficiency and operational lifetime of fluorescent devices.
Latest Patents
Kobori's latest patents include a method of driving a fluorescent print head and an image forming apparatus. This innovative method enhances the operational lifetime by reducing the evaporation of barium in the electron emitter material of a filament cathode. It also suppresses the deterioration of luminous efficiency. During the pre-luminous period, the grid voltage is controlled to a predetermined voltage, while the filament voltage is also maintained at a rated value or less. In the print luminous period, a grid voltage blank period is created, allowing for effective control of the anode voltage and grid voltage, thus optimizing the filament voltage.
Another notable patent is for a fluorescent luminous device that includes cathodes receiving independently controlled voltages. This device eliminates the need for independently controllable control electrodes and a power supply for applying a negative potential. It features multiple anode chains and filamentary cathodes arranged correspondingly, allowing for effective control of the anode dots.
