I wish to Display module only top of the page in joomla 1.5.9? in inner page it willl be invisible?

Like a developer or perhaps an administrator?

Like a template developer: If you are a developer, you can include your module within the template covered with the next tags:

<?php $menu = & JSite::getMenu();
if ($menu->getActive() == $menu->getDefault()) {
    -- module code goes here --
}
?>

Like a site administrator If you're a site administrator and simply want to show the module around the home page, open the module configuration, after which under menu assignment click "Choose Food Selection(s) in the list", then choose around the webpage of the site in the listing of menu pages and save the module.

Within the module configuration you are able to assign it to some specific food selection. Should you assign it by it will likely be displayed only around the webpage.
