Latest Patents

One of his latest patents is titled "Apparatus and method for quantitative evaluation of braze bonding length with use of radiation." This invention provides an apparatus that quantitatively evaluates a braze bonding length by utilizing a radiation emission unit. The unit emits radiation to multiple partial specimens, which are obtained by cutting a specimen in a plane perpendicular to the braze bonding length direction. A light generator produces light corresponding to the intensity of transmissive radiation, and an imaging unit photographs this light. A calculator then determines the braze bonding length of each partial specimen based on the correlation between the light amount and the braze bonding length. The overall braze bonding length of the specimen is calculated by totaling the lengths of the respective partial specimens.

Another notable patent is the "Thickness measurement apparatus and method thereof." This invention includes an ultrasonic wave transmission/reception device that measures the thickness of a pipe covered with heat insulation material. The device supports the ultrasonic wave transmission/reception from the outer surface of the pipe. A thickness calculation device measures the propagation time of the ultrasonic wave and calculates the thickness of the pipe. Additionally, a calibration board with a predetermined thickness is used to ensure accurate measurements.
