<script type="text/javascript">
var lastScrollY=0;
function heartBeat(){ 
   diffY=document.documentElement.scrollTop; 
   percent=0.1*(diffY-lastScrollY); 
   if(percent>0)percent=Math.ceil(percent); 
   else percent=Math.floor(percent); 
   document.getElementById("sorollDiv1").style.top=parseInt(document.getElementById("sorollDiv1").style.top)+percent+"px";
   lastScrollY=lastScrollY+percent; 
}
window.setInterval("heartBeat()",1);
</script>
<div id="sorollDiv1" style="width:180px; height:50px; right:30px;position:absolute;top:170px; text-aling:right;">
