  • Publication number: 20240008761
    Abstract: An evaluation method is performed by an arithmetic circuit and includes obtainment processing (S1), evaluation processing (S2), and presentation processing (S3). The obtainment processing (S1) obtains: image information on a sectional image representing an interested section of an organism including a target section of a testis of the organism generated by use of magnetic resonance of hydrogen atoms; and concentration information on a creatine concentration in the interested section measured by use of magnetic resonance based on chemical exchange saturation transfer. The evaluation processing (S2) generates an evaluation image representing a distribution of evaluation results of a testicular function in the target section based on the concentration information. The presentation processing (S3) presents the sectional image and the evaluation image.

  • Patent number: 11835910
    Abstract: A power source apparatus including a control unit configured to output a control signal to a switching element to switch a target voltage of an output voltage from a transformer. In a case of increasing the output voltage, the control unit outputs the control signal having a first duty when the target voltage is lower than a first threshold value, and outputs the control signal having a second duty larger than the first duty when the target voltage is switched to a value equal to or higher than the first threshold value. In a case of reducing the output voltage, the control unit outputs the control signal having the second duty when the target voltage is equal to or higher than a second threshold value, and outputs the control signal having the first duty when the target voltage is switched to a value lower than the second threshold value.

  • Publication number: 20230378718
    Abstract: In the wavelength variable light source and its control method of the present disclosure, intensity of oscillation light in a plurality of non-operating ports of MMI is utilized in consideration of filter characteristics between an operating port and a non-operating port that does not directly contribute to oscillation operation. By controlling the RTF laser so that the light intensity of the wavelength of the oscillation light in the monitored non-operation port is in a desired relationship, a wavelength variable light source reflecting SMSR characteristics is realized. The SMSR can be effectively controlled only by adding a photodetector to a non-operation port which has not been considered by the RTF laser of the prior art. In the wavelength variable light source, the inspection of the SMSR and the SMSR monitor during actual operation can be realized by a simple mechanism.
