Title: Separation device
Inventor: TAKAYAMA TORU
IPC: H01H85/02
Filed: 1989-03-08
Abstract: PURPOSE:To simplify structure and cut cost for a pair of auto-exothermic resistors by linking them together through a low temperature solder that melts when its temperature is raised to a predetermined level, and by externally engaging a cylindrical arc- extinguishing resin with the resistors in such a way that it can slide freely, so as to ensure cutoff of dynamic current. CONSTITUTION:When an arrester 2 deteriorates and cannot cut normal voltage to ground, and leakage current is increased, resistors 11, 12 become self-exothermic, and when the temperature reaches a predetermined level, a low temperature solder 13 between the resistors 11, 12 melts. The resistors 11, 12 are separated vertically at high speed by the force of tensile spring. As the resistors 11, 12 are engaged in an arc-extinguishing resin 20, a prearcing part is confined in a narrow space. At the prearcing point, high temperature gas is generated as well as arc, and, being confined in the narrow space, becomes rapidly of high pressure. The surface of the arc- extinguishing resin 20 is affected by the arc and an arc-extinguishing vapor such as H is generated. The arc is extinguished in a short period of time owing to the rapid increase in gas pressure and the generation of the arc-extinguishing vapor, whereby dynamic current due to the normal voltage to ground at a charging part of such as a distribution line is cut off.

Title: Flaw inspecting method for appearance inspecting device

IPC: G01N21/958
Filed: 1994-03-02
Abstract: PURPOSE:To detect a scratch on the surface of translucent glass product with high accuracy by condensing a label made of multiple dots into one point, and judging the intensity values of picture elements on a straight line obtained from the addresses of two condensed scratch candidate points. CONSTITUTION:The image of an object to be inspected (translucent glass product) taken into an image input means is binarized, and a scratch on the surface is extracted. When the calculated label area is a set value or above, the object has a scratch (defective), and the inspection is completed. When the label area is the set value or below, i.e., when a thin scratch exists on the surface of the object, the shrinking process is applied to intermittent points, and a flock of several dots are condensed into one point to judge whether the intermittently existing labels are a scratch or not. Addresses of two optional points among the condensed scratch candidate points are calculated, the equation of a straight line is calculated, and whether it is a scratch or not is judged in consideration of the ratio that the intensities of picture elements on the straight line exceed a prescribed threshold value and the length of the straight line.
