Title: Diffusion symbol capturing circuit
Inventor: KUWATSURU KEIICHIRO
IPC: G01S19/37
Filed: 1991-10-14
Abstract: PURPOSE:To shorten the time required in capturing in a dispersion symbol capturing circuit, which is used to synchronously capture the dispersion symbol of a GPS satellite electric wave. CONSTITUTION:A shift register 20 emits dispersion symbol signals P1-Pn, which are phase delayed bit by bit. These are entered into a sensing part 30, and the error etc., in the Doppler shift frequency, etc., between the satellite signal and the dispersion symbol signal of the satellite is removed according to the exclusion theory with the signals NI, NQ, etc., given from an NC transmitter 60 and the dispersion symbol signal of the satellite. The remaining signal components are counted by a sampling clock CK, and the correlation result is emitted. A control part judges capture of the dispersion symbol of the satellite signal by searching the maximum among the output data. In case nothing is captured, the search is made while the phase of the dispersion symbol signal PA is shifted in conformity to the control signal given by the control part 70, which is made repetitively until capturing takes place. Thus the dispersion symbol can be captured at a high speed by performing simultaneous searching using sensors in 'n' pieces.

Title: High-accuracy surface configuration measuring method and device
Inventor: GOTO TAKAYUKI
IPC: G01B7/00
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To markedly enlarge a measuring range along height by inputting a signal of the difference between a detected physical quantity and a target value to a drive mechanism, and operating a coarse adjustment mechanism so that the amount of displacement of a driven mechanism is held constant. SOLUTION: The distance between a probe 1 and a subject 12 for measurement is detected from physical quantities such as tunnel current, electrostatic capacity, interatomic force, and optical, acoustic, and dynamical variations. A signal of the difference between each of the detected physical quantities and a desired value for keeping the physical quantity constant is input to a coarse adjustment mechanism 3 and a fine adjustment mechanism 2. As a result, the mechanisms 3, 2 are controlled simultaneously, so the mechanism 3 whose response speed is lower than that of the mechanism 2 operates to correspond to measurements of the components with larger amplitude of a surface configuration.  Therefore, the mechanism 3 is operated in such a way as to hold the amount of variation of the mechanism 2 constant, so as to enable a measuring range along height to be significantly increased without lowering measuring resolution.
