| Abstract | A high-reliability SR-UEW polyurethane wire for use in sealed relays has been developed. SR-UEW is a magnet wire that minimizes the amount of organic gas emitted by the wire insulation and uses no lubrication or oils for surface treatment, without sacrificing windability in the coiling process. Analysis of generated organic gases showed little cresolic acid, which adversely affects relay contacts, and no paraffin was detected. As a result, the life of relay contacts was greatly extended compared to that of relay contacts using the conventional product and the degassed conventional product. Specifically, this product showed a life 10 to 100 times longer than that of conventional urethane wire. The amount of gas generated over long periods is about one-fourth of that generated by the degassed conventional product.< |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
