IPC: H05K3/46
Filed: 1992-03-27
Abstract: PURPOSE: To obtain a method by which the positional deviation between layers in a multilayer body containing conductors can be detected by appropriately positioning a hole formed through the multilayered body for electrically connecting different layers to each other. CONSTITUTION: In a positional deviation detecting method, the relative deviation of layers constituting a multilayered laminated body 4 containing conductors is detected so as to position the multilayer laminated body serially formed to electrically connecting conductor planes to each other to a hole formed through the laminated body. Each layer has optically distinguishable patterns 15 and 16 at clearly defined positions, with the patterns 15 and 16 being partially matched to each other in the laminated body 4, and at least one inspection hole 14 is formed in the body 4. Therefore, the hole 14 intersects the patterns 15 and 16 in the body 4 and the cut edges of the patterns 15 and 16 are optically detected in the hole 14.

Title: Inspecting instrument
Inventor: TANAKA MIKIO
IPC: G01B21/02
Filed: 1985-04-04
Abstract: PURPOSE:To prevent deviation of a reference set value by a mechanical impact at the time of measuring by preventing contacting of a dimension measuring means with an object to be measured. CONSTITUTION:A carriage base 1 conveyed in a specific direction on a rail 2 is first confirmed on its existence by existence detectors 4 and 5 and its height dimensions are measured by a dimension measuring instrument 3. Then, in case the height dimensions of the carriage base 1 are decided to be out of the allowable limits at this stage by a comparing and deciding circuit 7, a rail 9 is moved and the carriage base 1 is removed from a conveying line at a point of time when it is detected that the carriage base 1 is conveyed to the position of the rail 9 by an existence detector 8. Accordingly, since the dimension measuring instrument 3 does not contact with the carriage base 1, the mechanical impact at the time of measuring is not transmitted to the dimension measuring instrument 3 and the reference set value is not deviated.
