Latest Patents

Kazuo Nakajima holds a patent for a "Hole shape measuring method and apparatus." This invention involves a measuring apparatus where an arm is lowered to insert a measuring sphere into a hole in a workpiece. The measuring sphere is then lowered in the depth direction of the hole. The back pressure of compressed air is detected at multiple locations by an air/electricity (A/E) converter. The detected values are compared with a master reference value by a controller, which converts the detected values into the inside diameter of the hole. This method allows for the accurate measurement of various hole shapes.
