Latest Patents

Murakoshi's latest patents include a radio frequency amplifying device and a magnetic resonance imaging (MRI) apparatus. The radio frequency amplifying device features amplifying circuitry, obtaining circuitry, and correcting circuitry. This device is designed to output an amplified signal by enhancing the input signal. The obtaining circuitry captures an envelope that represents the waveform of a radio frequency signal as digital data. The correcting circuitry then adjusts the obtained envelope based on the amplifying circuitry's rising characteristics, ultimately feeding the corrected signal back into the amplifying circuitry.

The RF circuit and MRI apparatus patent includes a directional coupler, processing circuitry, and an adjuster. The directional coupler has ports for outputting both traveling and reflected waves. The processing circuitry calculates the impedance of the load side as viewed from the coupler, utilizing the voltage standing wave ratio and the phase of the reflected wave. The adjuster modifies the output from the ports based on the calculated impedance, enhancing the overall performance of the RF circuit.
