Newly Issued Patent for Applying a Conductive Coating onto an Insulator of an X-Ray Tube

LAFOX, Ill., March 15, 2022 (GLOBE NEWSWIRE) -- Richardson Electronics, Ltd. (NASDAQ: RELL), which is a global provider of engineered solutions for diagnostic imaging equipment, is pleased to announce the issuance of U.S. Patent No. 11,257,652 (the ’652 Patent). The ’652 Patent is a result of Richardson’s innovative healthcare solutions for replacing X-ray tube components. Richardson’s newly-patented solution provides a unique conductive coating to an X-ray tube insulator. The insulator is easier to manufacture, prevents component failure, and increases recyclability. The coating can be advantageously applied at a relatively low temperature that does not negatively impact sensitive portions of the insulator. The innovative solution also reduces waste, as the coating can be reapplied numerous times to the ceramic components. The ’652 Patent is yet another confirmation of Richardson’s desire for providing its customers with the latest technological advancements.

“We are thrilled to receive this patent from the U.S. Patent Office. Richardson Healthcare’s engineering team develops solutions to help reduce the cost of healthcare. New solutions like the conductive coating not only reduce the cost of the tube, making it more affordable for hospitals but also allow us to recycle components which in turn reduces waste,” said Wendy Diddell, Richardson Electronics’ Executive Vice President and Chief Operating Officer.

Richardson Healthcare plans to introduce this technology in its future CT tube manufacturing programs.
