Title: Innovations by Yoshimitsu Takashima
Introduction
Yoshimitsu Takashima is a prominent inventor based in Anjo, Japan. He has made significant contributions to the field of fuel injection systems, holding a total of 10 patents. His work focuses on enhancing the efficiency and reliability of fuel injection technology.
Latest Patents
One of his latest inventions is a defective-portion detector for fuel injection systems. This device features a detecting portion that identifies variations in fuel pressure as a fuel pressure waveform, utilizing data from a fuel pressure sensor. It includes a computing portion that calculates various injection-rate parameters necessary for identifying an injection-rate waveform corresponding to the detected fuel pressure waveform. Additionally, the detector has a determining portion that assesses whether each learning value of the injection-rate parameters is abnormal. An identifying portion then determines the defective portion in the fuel injection system based on the combination of abnormal learning values identified.
Another notable invention is a fuel-injection condition detector. This device approximates multiple fuel pressure values representing descent or ascent pressure waveforms into a least-squares approximate line using the least-squares method. It also incorporates a weighting portion that applies a weight to the fuel pressure value, with the weight increasing as the difference between the fuel pressure and the least-squares approximate line becomes larger. The weighted values are then approximated into a weighted approximate line through the least-squares method.
