Latest Patents

One of his latest inventions is a magnetic particle imaging device. This device utilizes a static magnetic field generator to create a non-magnetic field region. An AC magnetic field application instrument then applies an AC magnetic field to this region. A detection coil, aligned with the direction of the AC magnetic field, detects a magnetization signal. Additionally, a measuring instrument is connected to the detection coil. A resonance frequency variable device, which includes a capacitor connected in parallel to the detection coil, adjusts the resonance frequency of the detection coil and measuring instrument. The capacitor's capacity is fine-tuned to ensure that the resonance frequency of the closed circuit aligns with the frequency of a harmonic signal.

Another notable invention is related to rotary electric machines. This invention includes a drive device that features a first inverter and a second inverter, each designed to drive two rotary electric machines. The carrier signals controlling these inverters are set to be in mutually opposite phases. To maintain balance, a balance capacitor and a balance inductor are placed between the connection lines of the inverters and ground potential. This setup ensures that the impedance to ground generated by one rotary electric machine matches that of the other.
