Title: Clock pulse disconnection detection circuit
Inventor: MURAKAMI KAZUHIRO
IPC: G06F11/00
Filed: 1985-12-20
Abstract: PURPOSE:To detect clock pulse disconnection even in a circuit assembled in a gate arrays by adopting the constitution that a clock pulse disconnection detecting circuit is constituted by logic elements only. CONSTITUTION:When a clock pulse is inputted continuously to an input terminal IN, the result of detection of a D flip-flop 4 outputs a high level to an output terminal OUT. When the clock pulse input is interrupted, the output of the oscillator 1 goes to a high state, after a 1/2 frequency-divider 2 and an RS flip-flop 3 are reset, the output of the oscillator 1 goes to a low state, since the output of the 1/2 frequency-divider 2 remains at a low level and is not inverted, then the D flip-flop 4 reads the low level and a low level is outputted to the check result output terminal OUT. While the oscillator 1 outputs a low level, when >1 clock pulse is inputted, it is detected.

Abstract: PURPOSE:To scan the probe of a scanning type tunnel microscope(STM) with high resolution over a wide range by supporting multiple points of a bar with displacement elements, and displacing one end of the bar. CONSTITUTION:Fulcrums A and B are displaced in the plane vertical to the axial direction of a probe 1 by piezoelectric elements 4-7. The distance between the fulcrum A and the tip of the probe 1 and the distance between the fulcrum B and the tip of the probe 1 are set to 11 and 12 respectively. The displacement of the tip of the probe 1 by the displacement of the fulcrum A is expanded or shrunk by 12/(11-12), and the displacement of the fulcrum B is made 11/(11-12) times. When piezoelectric elements 5 and 7 or piezoelectric elements 4 and 6 are concurrently displaced by the same quantity, the displacement of piezoelectric elements is expanded by (11+12)/(11-12) at the tip of the probe 1.
