Latest Patents

Kakefuda's latest patents include an optical axis adjustment device for X-ray analyzers. This device features an incident-side arm, a receiving-side arm, an X-ray source, an incident-side slit, and an X-ray detector. It incorporates a shielding strip that blocks X-rays received by the detector from the source. Additionally, it has a shielding strip-moving device that rotates the shielding strip around the sample axis to two angle positions. This innovation allows for the determination of the amount of deviation in parallelism of the sample surface concerning the optical axis of the X-rays based on intensity values detected.

Another significant patent is the optical axis adjustment method for X-ray analyzers. This method includes a series of adjustment steps: aligning the 0° position of the receiving-side arm and the angle of diffraction, adjusting the incident-side slit position, and ensuring the centerline of the X-rays is parallel to the sample surface. These adjustments utilize the capabilities of a one-dimensional X-ray detector to enhance positional resolution.
