Benefits of technology

This patented technology allows for effective cleaning without damaging or harming important components such as an inner rotor shaft inside a primary pump housing used during normal operations. It achieves this by providing high precision movement over large areas while reducing the amount of chemical agents needed compared with traditional methods like manual welders that require multiple hours' work effort. Additionally, there are no risk of contaminating sensitive equipment when performing these procedures due to its portability and ease of use.

Problems solved by technology

Technological Problem: The patented technology described by this patents relates to prevention or reduction of exposure from outside sources such as radiography doses that may affect health issues associated with workers who perform maintenance operations at different locations around the world's major facilities like Japan National Laboratories.
