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.

In some embodiments, a stamp comprising at least one stamping component and one stamping insert with a mounted band unit. The stamping component may comprise a top part and a bottom part with a cushion-receiving element. The mounted band unit may be connected so as to move synchronously via a reversing mechanism in the bottom part to the top part. In the resting position a text plate mounted on the stamping insert and a stamping area of the mounted band unit may abut against an ink pad soaked with ink in the cushion-receiving element. During a stamping process for producing a stamp impression the stamping insert can be shifted via the reversing mechanism into a stamping position. On the stamping insert, a height adjustment element for the mounted band unit and/or a text plate carrier may be provided.

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 stamp has a retaining seat, a moving seat, a spring, a handle, and a bottom cover. The moving seat is moveably mounted in the retaining seat. The spring is mounted on the moving seat and abuts the retaining seat. The handle is mounted on the moving seat and extends around the retaining seat. The bottom cover is mounted on a bottom of the retaining seat. The moving seat has a printing assembly and an ink-filling member. The printing assembly has a printing face and multiple ink-filling holes. The ink-filling member is mounted on the printing assembly and has multiple ink-filling tubes. Each one of the ink-filling tubes has a caliber smaller than a caliber of each one of the ink-filling holes. The printing assembly may perform the test print. The combining time of the stamp and operating time of the test print are also decreased.

A fixing device for a self-inking stamp includes a stop for a contact surface of a housing of the self-inking stamp and a latching element connected to the stop, wherein a front face of the latching element is designed for latching on an inner face of an operating part of the self-inking stamp. The latching element is also designed to rest, with a rear face of the latching element opposite the inner face of the operating part, on the housing of the self-inking stamp fixed using the fixing device. Also, a stamp device, includes the fixing device and a self-inking stamp having an operating part, a housing and an imprinting unit, wherein the self-inking stamp is fixed using the fixing device.

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.
