Latest Patents

One of Tachibana's latest patents is a "Peak point detector for ionized mass flow rate measurement." This invention involves a mass flow rate measuring apparatus that ionizes fluid at specific intervals. A voltage is sensed when the ionized flow mass is collected by an electrode downstream from the ionization point. The design includes a gate circuit that prevents electromagnetic radiation from being sensed as a signal for triggering a time measuring device. The voltage sensing circuit detects a point near or at the peak value of successive voltage waveforms, signaling the time measuring device for ion collection.

Another significant patent is the "Diagnostic monitoring device for closed loop air/fuel ratio control." This device utilizes at least one engine parameter to estimate the state of the gas sensor. It measures the frequency of the feedback control signal produced in the closed loop control system to determine if it is functioning normally. A logic circuit generates signals indicative of the system's performance, illuminating visual indicators based on the estimated state of the gas sensor and the feedback control signal frequency. Additionally, a gas sensor tester is included to detect the internal resistance of the sensor.
