Latest Patents

Among his most recent patents, Muramoto has developed a cathode ray tube resistance of ruthenium oxide and glass. This invention pertains to an electron gun used in cathode ray tubes, particularly in color television picture tubes. The design involves multiple electrodes aligned along the axis of the cathode ray tube's neck portion, with each electrode receiving an appropriate potential to focus and accelerate the electron beam produced by a cathode. A unique resistance element, made up of a ceramic substrate coated with resistive material, is strategically placed adjacent to the electrodes. This setup ensures that one end of the resistance element connects to the anode potential while the other links to a stem lead pin that maintains a low enough potential to prevent any mutual electric discharge. The consistency of thermal expansion coefficients between the substrate and the glass layer further enhances the resilience of this technology.

Additionally, Muramoto's invention of a flame detection apparatus features a detecting electrode positioned within the flame. This device utilizes a biasing circuit that includes a transistor connected to the detecting electrode, enabling the detection of the flame's impedance. The amplified AC signal derived from the transistor collector acts as a control signal for fuel supply management and for indicators, showcasing his innovative approach to safety and efficiency in flame detection.
