IPC: H04N7/18
Filed: 1988-09-27
Abstract: PURPOSE:To prevent a difference edge image from being divided by a reference edge image by leaving an edge part in an input edge image in a difference edge image as it is without finding out a difference when the directions are different between the edge part of the input edge image and the edge part of the reference edge image on the same position. CONSTITUTION:The data of the reference edge image on the same position are read out from a reference edge image storing means 4 while forming an input edge image by an edge image forming means 3, the read data are inputted to a comparing means 5 together with the input edge image and the means 5 compares the input edge image with the reference edge image to find out a difference. When edges exist in both the images under the consideration of the edge directions, the directional components of respective edges are compared, and when the components are different from each other, the edge of the input edge image is left on a difference edge image. Consequently, the difference edge image can be prevented from being divided by the reference edge image.

Abstract: PURPOSE:To enable a plating liquid to be well circulated, to uniformly adhere to a blind hole, and to be easily degassed by forming the BVH of a multilayered printed wiring board by plating the blind hole formed with a drill the diameter of which is gradually increased from the front end section. CONSTITUTION:A multilayered board composed of an insulating layer 1, internal- layer circuit 2, and metallic foil 3 is manufactured by integrally piling up an internal-layer material, resin-impregnated base material, outermost-layer metallic foil, etc. Then a blind hole 5 for BVH is formed together with or separately from a through hole. At the time of forming the blind hole, the hole is drilled from the surface of the metallic foil 3 by using a drill 4 with a tapered bit, the diameter d2 of which is gradually increased from a diameter d1 at its front end. As a result the diameter of the hole 5 is gradually increased toward the surface of the foil 3 from the innermost section of the hole 5. Then a plated layer 6 is stuck to the internal surface of the hole 5 by performing plating, for example, copper plating to the internal surface. Therefore, a BVH having high plate connecting reliability is formed, because the plated layer 6 is uniformly stuck to the internal surface of the hole 5.

Abstract: PURPOSE:To detect the occurrence of partial hydroplaning by analyzing the frequency of the high-frequency vibration contained in the output signal of a vehicle speed sensor, and comparing it with the reference value during a travel on a dry road. CONSTITUTION:The output signal of a wheel speed sensor 1 is filtered by a plurality of band pass filters 21, 22... Sn and inputted to a CPU 3.
