IPC: H04N7/18
Filed: 1995-05-12
Abstract: PURPOSE: To easily detect a complicated indication on road by recognizing the indication drawn on a road surface according to a window position which is good in symmetry with an edge position. CONSTITUTION: The edge position detecting means of a microcomputer scans an image on a display device 9 horizontally along a line A from the left side to the right side of the figure and finds the differential signal of this image on the line, namely, the part where a difference in luminance is large to detect the edge position of the image. Further, the symmetry evaluating means of the microcomputer evaluates the right-left symmetry of the image in a window 14 moving horizontally along the line A in every one pixel unit, and finds the window position where the symmetry of the image in the window 14 is good. The window 14 is set nearby a pixel which is being scanned and encircles a specific range of the image. Thus, the road sign drawn on the road surface is recognized on the basis of the edge position and the window position which is good in symmetry.

Title: Method for inspecting defect of pneumatic tire
Inventor: TSUJI NAOTAKA
IPC: G01M17/02

Abstract: PURPOSE:To improve accuracy in judgment for quality of a tire by detecting the amounts of displacements at an outer surface for different compressing forces, and detecting the difference in displacements, the average value of the differences in displacements and the distributing state at each part in the circumferential direction. CONSTITUTION:Compressing force of a displacement sensor 7 for a tire 1 is set at about 0.3 - 0.5kg with a position adjusting device 10. Then, a rotary encoder 5 is reset, and a motor 3 is driven. Thus the tire 1 is rotated for the entire surface. The first displacement data S1n(n=1, 2... 600) are stored in a memory device 11. Then, a compressing cylinder 8 is actuated, and the compressing force is changed into 20kg which is larger than the compressing force in the first measurement. The second displacement data S2n are stored in the device 11. The data S1n and S2n obtained in this way are supplied to an operating circuit 12, and the difference in displacement at each measuring position is obtained around the entire surface of the tire. The average value of the displacement differences and the standard deviation representing the distribution state of the deviations are also obtained. In a judging circuit 13, the quality of the tire is judged based on the obtained average value of the displacement difference and the obtained standard deviation.

Abstract: PURPOSE:To suppress the occurrence of a disconnection defect and to improve reliability by burying in advance a metal layer only in an opening for contact with a semiconductor element region, bringing the surface in coincidence with the surface of an insulating film, and then selectively forming a metal layer on the insulating film in contact with the buried layer. CONSTITUTION:An insulating film 3 is selectively etched to form openings for contact with a semiconductor substrate 1 and a diffused region 2, and the openings are buried to form a metal layer 4 on the whole surface so as to become thicker by 0.1-1.0mum than the surface of the film 3. A flat silica film 5 is formed on the layer 4, the film 5 and the layer 4 on the film 3 are so removed as to expose the surface of the film 2 by an anisotropically etching method, the layer 4 remains only in the opening to flatten the surface. A metal layer 6 is deposited on the whole surface, selectively etched to connect the substrate 1 to the region 2, thereby forming electrode wirings extended on the film 3. Thus, the cause of disconnection in the opening (step difference generated by the thickness of the wirings) is eliminated to improve the reliability.
