Title: The Innovations of Takeshi Yoshizawa
Introduction
Takeshi Yoshizawa is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of pressure detection technology, holding a total of four patents. His work focuses on enhancing the efficiency and reliability of pressure sensor devices.
Latest Patents
Yoshizawa's latest patents include a pressure sensor device, control device, and pressure sensor unit. This innovative technology improves the efficiency of pressure detection by applying a positive-phase signal to a capacitance element from the opposite side of a coupling point in a control device. Additionally, another driver applies a reverse-phase signal to a different capacitance element from the opposite side to the coupling point. The control unit detects pressures applied to the capacitance elements based on potential fluctuations at the coupling point. Another notable patent is an input overvoltage protection circuit with a soft-start function. This circuit includes a PMOS transistor that acts as a switch between the input circuit and the system. A comparator compares the input voltage with a predetermined reference voltage to determine if an overvoltage occurs. The soft switching control circuit gradually turns on the PMOS transistor, suppressing sudden changes in load on the input side.
