Title: Method for repeated thermal shock test
Inventor: KUROKI HIRONORI
IPC: G01N3/60
Filed: 1979-12-28
Abstract: PURPOSE: To make possible to find the ability of withstanding cracking due to thermal shocks in a state based on real conditions by causing cracks in a test piece by flowing a primary high frequnecy current through dual eye heating coils for a short time to heat the test piece, then cooling it, and further repeating heating and cooling the test piece.  
     CONSTITUTION: Two rectangualr coils are disposed above the surface of a metal test piece slightly apart from it, and by flowing a primary high frequency current through the coils for a short time, a part of the test piece near its surface is heated. Then it is cooled, and further heating and cooling are repeated to cause cracks in the metal test piece: by so doing, cracks can be generated in parallel to the induced currents, the induced currents therefore do not flow around the tips of the generated cracks or all around the cracks, so that the cracks can be developed under the same conditions as those of actual heating and cooling.

Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for testing an optical member by which information caused by working trace can be removed and information caused by optical defect be extracted. SOLUTION: A knife edge 6a is arranged at a focal point of an optical member A to be tested. Therefore, an illumination light emitted from the knife edge 6a and entering the optical member A is made to be a parallel light through the optical member A, and it enters an image pickup device 7. Respective picture data sensed by an image pickup element 7 at the respective rotary positions of the knife edge 6a are differentiated respectively by a picture processing part 14 and then they are synthesized as one picture data. The picture data is changed into two data, that is, one picture data to be extracted from which only a high-frequency element is removed and the other picture data in which only a low-frequency element is remained. The latter is shifted by a slight quantity in a high luminance direction, and it becomes a threshold data.  Among respective picture elements comprising the former, those having higher luminance values than that of the picture element of corresponding threshold data are judged to have an optical failure and they are extracted as a result.
