A method is provided for extending the frequency band of an audio signal during a decoding or improvement process. The method includes obtaining the decoded signal in a first frequency band, referred to as a low band. Tonal components and a surround signal are extracted from the signal from the low-band signal, and the tonal components and the surround signal are combined by adaptive mixing using energy-level control factors to obtain an audio signal, referred to as a combined signal. The low-band decoded signal before the extraction step or the combined signal after the combination step are extended over at least one second frequency band which is higher than the first frequency band. Also proved are a frequency-band extension device which implements the described method and a decoder including a device of this type.

A plate carrier (1) for a self-inking stamp (5) and a method for producing a plate carrier (1) having an adhesive surface (9) for attaching a text plate (14) to a printing side (2) of the plate carrier (1), the plate carrier (1) having, on the printing side (2), a grid pattern (13) aligned in relation to the edges (3, 6, 7) of the plate carrier (1) for aligning the text plate (14) when attaching it to the plate carrier (1).

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.

Provided is a stamp unit comprises a case that accommodates an ink occluding member and a frame on which an impression member formed of a porous film is tightly stretched, and a leaf spring is provided between the case and the frame. By an elastic repulsive force of the leaf spring, the impression member and the ink occluding member are constantly separated from each other, and the ink is not allowed to penetrate the impression member during distribution. In this way, even when an unexpected external force is applied to an unprocessed stamp unit, the impression member and the ink occluding member do not come into contact with each other, and penetration of ink into the impression member is prevented from starting.
