Heading: 2003 Change to Five Liter Compressor

Text: Throughout the rest of 2003, Nihon Rufuto asked Nidek for even more changes. One significant change was from a three liter compressor to a five liter compressor. The five liter compressor increased the size of the motor, generated more noise, used more wattage and required some different parts. At Nihon 3 In his deposition, Ichida explained that in this email he meant only that he was pleased with the way the prototype looked and that he had not yet had a chance to evaluate whether the prototype met the specifications. 8 Rufuto’s request, Nidek worked on designing models with a three liter compressor and with a five liter compressor. Nihon Rufuto also asked for a redesign of the oxygen monitoring system board and tweaks to the cabinet design. At a July 2003 meeting in Birmingham, Nihon Rufuto inspected the three liter and five liter compressors. By January 2004, Nihon Rufuto planned to submit first the three liter model to Japan’s Ministry of Health and follow with the five liter model. In March 2004, Nidek shipped another three liter prototype with a 32 stroke compressor to Nihon Rufuto. After testing that prototype, Nidek determined that it met the oxygen purity, noise and wattage requirements. Nihon Rufuto’s own test results confirmed a 90+ percent oxygen purity and its electrical test was positive. Nihon Rufuto advised Nidek that Nihon Rufuto would proceed with the approval application with the Ministry of Health. Over the next several months Nidek worked to prepare the prototype and the documentation Nihon Rufuto needed for the application.
