Title: Surface inspection method for frp product
Inventor: YAMAGUCHI TERUHIKO
IPC: G01B11/30
Filed: 1989-01-31
Abstract: PURPOSE:To allow the well conduction of the surface inspection of an FRP product by Fresnel diffraction by adjusting the distance between a spot light source and an inspection surface and maximizing the S/N of an ordinary surface pattern and the pattern of a true defect. CONSTITUTION:Rays of the light source 1, such as ultra-high pressure mercury lamp, are imaged at a focus by a lens system 2 to form the spot light source 3. The surface 4 of the FRP product is irradiated with the ray thereof and the annular pattern is generated on a screen 5 by the Fresnel diffraction of the reflected light. The difference between the patterns is made distinct if the S/N of the annular pattern occurring in the undulation of the ordinary surface and the annular pattern occurring in the product defect is maximized by adjusting the distance (a) between the spot light source 3 and the inspection surface 4. A recessed part P is thus easily detected. The contrast is maximized near the distance a=50mm in this case.

Filed: 1988-01-29
Abstract: PURPOSE:To realize high-speed response and bistable operations with a liquid crystal element having a large area by forming fine grooves in one direction on the surface of a base plate by using a burnishing tool before or after forming electrodes. CONSTITUTION:Fine grooves are formed on a base plate 2 in such a way that the base plate 2 is moved while a tool 1 is pressed against the base plate 2 and a plastic deformation is given to the base plate 2 (burnishing method). Since the shapes of the grooves formed on the base plate 2 can be changed easily depending upon the shape and cutting quantity of the blade of the tool 1, grooves having a required shape can be formed easily. Moreover, when the grooves are formed at regular intervals, the grooves can be formed on the entire surface of the base plate at equal pitches. Furthermore, a liquid crystal element can be manufactured in such a way that fine grooves are formed on electrodes after the electrodes are formed on the base plate 2 made of glass, etc., and the base plate 2 is bonded to another base plate 2 with a certain gap between them, and then, ferroelectric liquid crystal is injected into the gap. Therefore, a liquid crystal element which is excellent in optical responding characteristic and large-area response can be obtained easily.
