This invention provides cholesterol absorption inhibitors of Formula, and the pharmaceutically acceptable salts and esters thereof. A translucent electrode overlies the coupling-out layer and an organic functional layer stack having organic functional layers overlies the translucent electrode. Furthermore, the system includes an optical detector mounted on the needle for obtaining optical information discriminating tissue in the body, for providing the fine guidance. The first and second signals may be synchronized according to, at least in part, aspects of their respective first sub-signals. By inputting an alternating signal inputted from an antenna to a charge pump circuit as it is or through a logic circuit, a charge pump can operate with a stabilized frequency that a clock frequency is not affected by a variation of elements and the ambient temperature, thus a stabilized boosting can be provided.
