Title: The Innovative Mind of Ryuu Saitou
Introduction
Ryuu Saitou is a prominent inventor based in Nagano, Japan. He has made significant contributions to the field of technology, holding a total of 4 patents. His work primarily focuses on developing advanced electronic circuits that enhance the functionality and safety of various devices.
Latest Patents
One of Ryuu Saitou's latest inventions is a temperature sensor circuit. This circuit is designed to prevent excessive overshooting voltage at the output terminal when a power supply is connected. It features a short-circuiting device that operates in parallel with a depletion mode NMOS, ensuring that the drain and source are short-circuited during power connection. Additionally, a delay device transmits a signal to the short-circuiting device for a specific duration, effectively preventing voltage overshooting.
Another notable patent is an igniter system that includes a coil failure detection circuit. This circuit monitors the rise of the collector current of an IGBT and utilizes a timer circuit to measure the duration of this rise. If the rise is abnormal, the electronic control unit determines that a coil failure has occurred. It then turns off the IGBT to prevent misfires and halts the flow of fuel gas to the combustion chamber, thereby protecting the catalyst from damage.
