His work has been instrumental in advancing the capabilities of image forming apparatuses and radiation image read-out methods.

Latest Patents

One of Nishihata's latest patents is for an image forming apparatus that features a light beam scanning device. This device includes a light source section, a deflector, and a reflection type optical system. The light source section is equipped with three laser light sources that utilize different modulation systems based on the corresponding semiconductor lasers. Specifically, the red-light and blue-light laser sources employ a direct modulation system, while the green-light laser source utilizes an external modulation system with an external modulator (AOD). The arrangement of reflecting mirrors, the deflector, and an arcsine mirror along the optical path ensures that the laser light is guided to a recording material without requiring correction for light beams of different wavelengths.

Another notable patent involves a radiation image read-out method and apparatus. In this invention, stimulating rays produced by a line light source are linearly irradiated onto a stimulable phosphor sheet that has stored a radiation image. The stimulating rays cause the sheet to emit light proportional to the energy stored during exposure to radiation. A line sensor, consisting of photoelectric conversion devices arranged along the length of the linear area, receives the emitted light. The sheet is moved in a direction different from the length direction of the linear area, allowing for effective operation processing on the outputs obtained from the photoelectric conversion devices.
