Filed: 1987-10-01
Abstract: PURPOSE:To lengthen the length of a low resistance layer between electrodes just under an anodizing film, to increase the resistance value of the whole low resistance layer and to improve sensibility by forming a plurality of trenches parallel with the electrodes to the surface section of a compound semiconductor held between the electrodes. CONSTITUTION:A compound semiconductor 2, electrodes 3 and an anodizing film 4 are shaped onto a substrate 1 as a high resistor. Since a plurality of trenches 5 are formed to the surface of the compound semiconductor 2 as a foundation to which the anodizing film 4 is shaped, the anodizing film 4 is formed onto an irregular surface including the trenches 5. The length of a low resistance layer is increased between the electrodes 3 owing to irregularities shaped by the trenches 5. Accordingly, the resistance value rs' of the low resistance layer in an equivalent circuit diagram for element resistance takes a large value, thus inhibiting the reduction of a combined resistance value.

Title: Device for inspecting distortion of plate material and method therefor
Inventor: UCHIUMI YOSHIJI
IPC: G06T7/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To inspect internal distortion of a plate material and/or the smoothness of the surface thereof by a method wherein an inspection pattern projected from a projector, which passes through a plate material forms an image on a first screen as projection image and that which is reflected on the surface thereof forms an image on a second screen as projection image, and the images are taken by first and second cameras to analyze. SOLUTION: An inspection pattern is projected by a projector 1 to pass through a sample plate 2 while being reflected on the surface thereof to present projection images on first and second screens 3 and 4. When a distortion exists at any point as the pattern passes, the projection image of the first screen 3 is deformed oval or into other shapes according to the degree of the distortion. When the smoothness at the position of the reflection is inferior, the projection image on the second screen 4 is deformed oval or into other shapes according to the degree of waving or the like. The projection images thus obtained are taken by the CCD cameras 5 and 6. Image signals of the projection image taken are sent to the image analysis section 7 to be binary coded by an image processing part 8 thereby enabling obtaining a round shape enough to limit a measuring range.  A distortion inspection part 9 calculates and judges a standard deviation ratio in the vertical and horizontal directions per round shape.
