Abstract: A splice sealing device including a first electric cable having an electrical conductor and an insulative cover, a second electric cable having a further electrical conductor and insulative cover, a junction joining the electrical conductors of the first and second electrical cables, a housing which has at least two housing parts mated to each other and which delimits an inner space for accommodating the junction, and a first cable exit in the housing. The first cable extends through the first cable exit, which includes a first chamber accommodating a first cable seal positioned on the first insulative cover of the first cable and sealing the first cable against the housing. The first cable exit is an integral part of a first housing part, and the first cable exit includes an annular wall axially delimiting the first chamber to the outside in extension direction of the first cable.

Abstract: There is provided a method of creating an index, which is executed in a document retrieval apparatus. The index includes index information and a trie, the index information includes an index item formed of a character string, the trie is formed of a plurality of nodes each including a part of the character string of the index item, and the index information and each of the plurality of nodes of the trie are associated with each other. The method comprises the steps of: dividing the index information by a unit of an index information block when a first node of the trie is associated with a plurality of the index information blocks, and a search time required for searching all the index information associated with the first node of the trie exceeds a predetermined first threshold; and associating the divided index information with the second node.

Abstract: Even an instrument with a small memory capacity realizes fast document retrieval through the use of a trie. A computer generates an index layered node by grouping the nodes in the trie as a family with relation to a parent node and layers the first and second tries with the index layered node as a border. The first trie is stored in a storage area of a main storage unit. The second trie is stored in a storage area of a secondary storage unit. When the computer accepts an input of a term to be retrieved, in the first and the second tries, the computer traces characters of a character string composing the term to be retrieved and then reaches the index information for the concerned character string. The computer reads the index information and retrieves a document having the term to be retrieved and a location of the document.
