A metallic stamp and die for the craft industry comprises a predetermined acid-etched design on a surface of a metallic plate. A first layer of a metallic paint is applied over the front and back surfaces of the metallic stamp and die. A second layer of a rubber paint is applied over the metallic paint. The metallic paint facilitates bonding of the rubber paint to the metallic plate and increases the life of the coating of the rubber paint. The rubber paint is configured to absorb and store an ink and facilitate transfer of the ink to one or more substrates, thus enabling stamping of the design on the substrate. The metallic die can be configured for a plurality of uses, such as embossing, cutting, heat-foiling, stamping, scoring, and inserting patterns or designs in a plurality of substrates.

Self-inking stamp comprises: a porous marking block; an ink storage body disposed on an upper surface of the porous marking block; an absorber disposed on an upper surface of the ink storage body and configured to generate a capillary force less than that of the ink storage body, and absorb excess ink from the ink storage body; an ink tank comprising an ink supply tube having an open distal end connected to the ink storage body; a wall member covering an outer lateral peripheral surface of the ink storage body in such a manner as to prevent ink leakage; an ink outlet opening provided in a part or an entirety of a lower surface of the ink storage body; and an air passage opening provided in at least a part of an outer lateral peripheral surface of the absorber in communicating relation with atmospheric air.

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.

An example ink cartridge for a stamp may comprise an image-forming component, a first ink-storage component made of an ink-absorbent material, a second ink-storage component made of an ink-absorbent material having one or more channels in it, and a frame made of a rigid, non-ink-absorbent material. The frame may comprise a floor having one or more holes in it. The frame may comprise an outer wall along its perimeter. The outer wall may extend up from the floor such that the outer wall is capable of retaining ink while the ink is being absorbed by the first ink-storage component and the second ink-storage component, thereby increasing the effective volume of the channel(s). The one or more holes may align with the one or more channels such that ink is enabled to flow through the hole(s) into the channel(s).

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.
