Title: Method for inspecting surface defect and its device
Inventor: HIRONO AYUMI
IPC: G01N21/88
Filed: 1992-10-09
Abstract: PURPOSE:To make easy detection of a defect of moderate recesses and projections of a surface on which a uniform membrane is applied to a base of metal and the like by detecting a change of an axial center direction boundary part of a projection light image having an end edge crossing at right angles with an axial center direction formed on the surface of a cylinder. CONSTITUTION:A projector 4 serves to form a belt-like projection light image 6 crossing at right angles with an axial center direction of a cylinder 1 for the surface of the cylinder 1. A light receiver 5 for making a visual field 7 of a boundary part 8 of the projection light image 6 is arranged and serves to receive reflection light in the neighborhood of the boundary part 8 in the visual field 7. In the case where a defect 3 exists on the surface 2 of the cylinder 1, a strain occurs on a projection light image end edge part of the boundary part 8 due to existence of the defect 3 and appears in the output of the light receiver 5. Accordingly a signal corresponding to the strain is analyzed for the purpose of detection of a defect on the surface. As the result, since the neighborhood of the boundary part in the longitudinal direction of the cylinder of the projection image formed on the surface of the cylinder is made a light receiving position of a line sensor constituting the light receiver, the detection of moderate recesses and projections defects of the surface is made easy.

Filed: 1991-07-20
Abstract: PURPOSE:To eliminate the errors in set and provided information such as confirmation of stable operation by comparing the output signal of a semiconductor pressure sensitive element with a detection threshold and a stable operation threshold to generate a detection output and a stable operation output. CONSTITUTION:A setting inputting means 2 is first operated in the state forming a minimum pressure value, and the output signal of a semiconductor pressure sensitive element 1 at this time is read as the lower limit value X of an effective pressure range. The means 2 is then operated in the state forming a maximum pressure value, and the output signal of the element 1 at this time is read as the upper limit value Y of the effective pressure range. Thus, the effective pressure range is set in an effective pressure range setting means 3. A threshold setting means 4 calculates and sets a detection threshold W on the basis of the effective pressure range, and also sets stable operation thresholds T, U on the basis of the effective pressure ranges X, Y and the threshold W. A judging means 5 compares the output signal of the element 1 with the threshold W and the thresholds T, U, and generates a detection output and a stable operation output, which are used as the information for sequence processing.
