Organic superlattices fromed by molecular layer epitaxy, and a novel MLE method of forming organic molecular monolayers are disclosed. Therefore, the present invention provides a low jitter clock regenerator comprises: an input clock; a divider to divide said input clock into a slower clock; a phase lock loop circuit to regenerate said slower clock to a reference clock; and a parameter transformer to tune said divider and said phase lock loop circuit to increase the adjustment speed of said phase lock loop circuit. The system further has a bent sub connected to the upper end of the motor. The silicide material being discontinuous in a terminal region of the second layer along the length of the fuse. The microcontroller is configured to control the radio communication section to transmit the puncturing allowing signal when the insertion detecting switch detects the specimen being inserted into the measuring device.
