Title: The Innovative Contributions of Makoto Asai
Introduction
Makoto Asai, based in Kariya, Japan, is a prominent inventor with an impressive portfolio of 22 patents. His work primarily focuses on advancements in semiconductor devices and fuel supply systems, showcasing his expertise and commitment to innovation.
Latest Patents
Among his latest patents, the first notable invention is a semiconductor device which includes innovative features for improved current detection. This device connects a resistor for detecting current between a source electrode and a current sensing electrode. The unique design ensures that the dielectric withstand voltage of the gate insulator is greater than the product of the resistor and the maximum current flowing through the detection device. Additionally, the diffusion length of the p-body region in the main device is shorter than that of the current detection device, enhancing performance under inverse bias conditions. This configuration helps in achieving a stronger electric field, resulting in earlier avalanche breakdown in the main device compared to the current detection device.
The second significant patent is a sophisticated fuel supply system which features an electronic control unit that effectively manages fuel pressure for a low-pressure pump based on engine status. This system incorporates a fuel pump controller that generates driving signals for the pump, using feedback control to ensure the actual fuel pressure aligns with the target. It also introduces a lower limit guard value to enhance safety, particularly by setting a duty ratio of 0% when the engine is stopped.
