Abstract: A connector (1) includes: a terminal receiving chamber (3) provided in a connector housing (2) and configured to receive therein (3) a terminal; and a potting material filling portion (9) provided in the terminal receiving chamber (3) with a potting material filled in the potting material filling portion (9), thus allowing the potting material filling portion (9) to seal the terminal receiving chamber (3). With respect to the potting material filling portion (9), based on an occurring stress characteristic showing a filling amount of the potting material relative to a stress occurring in the potting material filling portion (9) and based on a peel strength characteristic showing the filling amount of the potting material relative to a peel strength of the potting material filling portion (9), the filling amount of the potting material is set within such a range as that the peel strength becomes larger than the occurring stress.

Abstract: An electronic book which permits retrieval and visual presentation of information from memory such as floppy disks or laser cards in the same fashion as books, magazines or newspapers. Renewal of information in the paperless book may be effected by changing, for instance floppy disks or by receiving information on the air or over the telephone and putting the so-received information in the inner memory of the paperless book. The paperless book permits an individual reader to read sequential visual presentations of information at a speed at which he can read books, magazines or newspapers.
