Latest Patents

One of his latest inventions is the Measurement X-ray CT apparatus. This apparatus calibrates the geometrical positional relationship between the focus of an X-ray source, an X-ray detector, and the rotation center of a rotating table in advance. It obtains projection images by irradiating the object to be measured with X-rays, performing a CT scan, and generating a three-dimensional image through CT reconstruction of the projection images. The apparatus includes a reference frame made of a material that is less susceptible to environmental changes, along with sensors that obtain calibration values during the CT scan. These calibration values are crucial for the CT reconstruction process.

Another notable invention is the Non-contact surface roughness measuring device. This device is designed to avoid damage caused by collision with a workpiece while ensuring that a non-contact surface roughness probe is set at an appropriate position relative to the measurement surface. It features a non-contact surface roughness probe and a touch-signal probe attached to the tip of an arm of a coordinate measuring machine. The touch-signal probe detects contact, allowing the non-contact surface roughness probe to be positioned optimally relative to the workpiece.
