Research and product development
Nihon Dempa Kogyo has developed a prototype crystal-based disease detector which diagnoses disease from breath. The system works by detecting trace amounts of odor-causing substances found in a person's breath.
NDK's Belvidere, Illinois facility was heavily damaged in 2009 when one of the crystal autoclaves ruptured violently, causing an explosion. The explosion scattered debris over a wide area, with a 7-foot support beam striking and killing Ronald Greenfield of Chesterfield, Indiana, who was refueling at a nearby truck stop. Debris also damaged a nearby automotive supply company, injuring one worker. The rupture was in a crystal-growth autoclave that had undergone stress corrosion cracking and was inadequately inspected; recommendations from a previous incident were ignored. As a result, the autoclave became overstressed and failed completely. After an investigation, OSHA fined NDK $510,000 for a history of ignoring safety recommendations.
Demolition of the facility began in March 2015, with no plans to rebuild.
