Abstract: An evaluation method uses a Talbot imaging apparatus. In the evaluation, an evaluation target is a brittle material having a high transmittance (I/Io) of an electromagnetic wave including light and having a defect part. The method includes: imaging the evaluation target to obtain a small-angle scattering image; obtaining a scattering signal intensity of the defect part from the small-angle scattering image; and calculating depth-direction information of the defect part from the scattering signal intensity.

Abstract: A reverse type stamp includes an outer cylindrical body, an inner cylindrical body which is movable relative to the outer cylindrical body, an elastic member that constantly urges the inner cylindrical body in a protruding direction inside the outer cylindrical body, an inversion body which is reversed and returned in synchronization with the relative movement, and a print body which is joined to the inversion body. When the outer cylindrical body is pressed down while the inner cylindrical body stands on a paper surface, the inversion body is reversed inside the inner cylindrical body for an imprinting operation. An ink pad is provided inside a movable container inside a cartridge. The movable container is elastically supported inside the cartridge by a coil spring provided at a rear surface thereof. Since contact between the ink pad and the print body is buffered, the sagging of the ink pad can be prevented.

Abstract: A self-inking stamp is configured such that, in a marking preparation state, a marking member is maintained in a state in which it is oriented upwardly within a stamp body of the self-inking stamp and pressed against an ink pad to supply ink thereto, and, during a marking operation, after the inner frame is moved downwardly while being reversingly rotated and oriented downwardly, the downwardly-oriented marking member is exposed from the stamp body and enabled to make a mark. The self-inking stamp is also configured to lock the marking member in a state in which it is exposed from the stamp body, for replacement and cleaning of the marking member.
