Title: Displacement gauge and displacement measuring method, and thickness gauge
Inventor: AKISHIBA YUUJI
IPC: G01B11/06
Filed: 1993-10-14
Abstract: PURPOSE:To measure the displacement on the surface of an object to be measured with no difference by projecting a light onto an object to be measured while an objective lens is shifted along a light axis and determining the position of the objective lens at the time when the focal point of the light is formed on the object. CONSTITUTION:As an objective lens 15 is shifted along a light axis, the distance between the lens 15 and an object 16 to be measured varies. When it becomes equal to a predetermined distance, the focal point of the projected light onto the object 16 is formed on the object 16. Then only a reflecting light from the focal point position passes through a light-converging part 17. A photo-diode 18 receives it and the light- receiving quantity of the photo-diode 18 becomes the maximum. A signal corresponding to the light-receiving quantity is inputted into an amplifier 19 and further the amplifier 19 inputs an output signal X into a calculation part 20. The position of the lens 15 at the time of the maximum light-receiving quantity is correspondent to the distance between the reference point of an optical system and the object 16. The object 16 is shifted along the direction crossing a light axis at a right angle so as to measure the displacement on the surface of the object 16.

Abstract: PURPOSE:To secure a stable transmission line which is scarcely influenced by a load variation by inserting a circuit which goes to a high impedance and a low impedance by a commercial frequency and a signal frequency, respectively, in parallel to both a power source supply end and the last load end of a low voltage distribution line. CONSTITUTION:A bypass capacitor 12 is inserted in parallel to a transformer 11 to the vicinity of a commercial transformer 11 of a commercial power source supply side of a low voltage distribution line 1, and also a bypass capacitor 13 is inserted into the last load side. These capacitors 12, 13 select a capacity value which goes to a lower impedance and a higher impedance by a use frequency and a commercial frequency, respectively, than an impedance of a load 10 connected to the low voltage distribution line 1. In such a way, a transmission line impedance by a signal frequency always goes to low, and a variation by on-and-off conditions of the load goes to small. Accordingly, most of signals from a current transformer 14 flow through a closed loop of the low voltage distribution line 1 and the capacitors 12, 13, and can be extracted by a current transformer 15.

Abstract: PURPOSE:To decrease the number of processes, and to reduce the whole stepped sections by constituting a scanning line of a first metallic wiring positioned under a signal conductor and a second metallic wiring connected to a gate electrode for a thin-film transistor and the metallic wiring through an opening formed to a layer insulating film. CONSTITUTION:A first layer metallic wiring 18 is shaped onto an insulator substrate 11 or an insulating film flatly formed onto the substrate. Consequently, since there is no stepped section in a foundation and there is no possibility of disconnection, a comparatively thin film may be shaped, a layer insulating film 16 and a second layer metallic wiring 17 are formed onto the film, and connected to the first layer metallic wiring 18. The second layer metallic wiring 17 in a crossed section is used as a scanning line connected to a gate electrode for a thin-film transistor. Accordingly, since the first layer metallic wiring 18 is shaped to a flat section, the wiring 18 may be thinned, and second layer metallic wirings 17, 17' are thickened. However, a point A in the figure represents the highest position and a point B in the figure the lowest position, and the difference of the height represents the sum of the thickness of a gate insulating film 14, the gate electrode 15 and the second layer metallic wiring 17, thus further thinning these films.
