The present disclosure provides belts having rod retains provided by way of an end module and a link cap for easier disassembly. According to an aspect of the present invention, each pixel of CMOS image sensor includes a photo detector that includes an electon Collection layer doped with a concentration of 5\xd71015cm3 to 2\xd71016cm3; and a transfer transistor that is connected to the photo detector and is formed of a vertical type trench gate of which the equivalent oxide thickness is 120 \u212b or more. The apparatus further includes a rack and gear mechanism affixed to the bracket member. A channel region of the first transistor and a channel region of the second transistor have a shape which is line-symmetrical with respect to a reference line. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug.
