  • Publication number: 20070262909
    Abstract: An inverted-F antenna and a mobile communication terminal using the same. The antenna includes a flexible board and a radiation plate formed on the flexible board. The antenna further includes a signal line having a first end formed on the flexible board and connected to the radiation plate and a second end extending from the first end and provided as a connecting terminal for feeding and grounding. The mobile communication terminal includes an RF board, a ground plate formed on the RF board, a feed line formed on the RF board for supplying a signal, and the inverted-F antenna as described above.

  • Publication number: 20060058346
    Abstract: The disclosure concerns novel enantiomers of tetrahydroisoquinoline derivatives and their pharmaceutically acceptable salts, their preparations and pharmaceutical compositions. The enantiomers of tetrahydroisoquinoline derivatives are provided which are useful in stimulating heart rate and hypotensive activity, inhibitory activity against platelet aggregation, and suppressive against inducible NO synthase. The enantiomers of tetrahydroisoquinoline derivatives and their pharmaceutically acceptable salts are effective for treating congestive heart failure, hypertension, thrombosis, inflammation, septicemia, cardiac insufficiency, and disseminated intravascular coagulopathy.
