  • Patent number: 11466410
    Abstract: A method of producing a lid including a top plate and a side wall extending downward from a periphery of the top plate, using molds, the molds including a papermaking mold and a drying mold. The top plate is provided with an abutting part abutting against an edge of an opening of a container, while an undercut part to be fitted to a lower part of the edge is formed on the side wall so as to be located below the abutting part. The papermaking mold is provided with suction holes at a level corresponding to a level of the undercut part formed on an inner surface of the side wall. The side wall is suctioned using the suction holes when a molded article is at least in one of several states to form the undercut part in a convex shape on the inner surface of the side wall.

  • Patent number: 11407565
    Abstract: A method of forming an undercut which is engageable with an edge, on a side wall of a cover intermediate body using a cover intermediate body and a secondary processing die. In the secondary processing die, a moving inner core has, on the outer surface thereof, a concave shape corresponding to a convex shape of the inner surface of the undercut. The moving inner core is made up of a plurality of core segments which are arranged along the circumferential direction. Each core segment is vertically movable along an inclined surface of a core. When the moving inner core is moved upward, the moving inner core transforms smaller than the inner diameter of the side wall of a cover. The slide core has, on the inner surface thereof, a convex shape corresponding to the concave shape of the undercut.

  • Patent number: 6714227
    Abstract: In an image forming apparatus using an indirect transferring method, an ink ribbon is selectively heated by a thermal head, in a state where an intermediate transfer film and the ink ribbon are put one on the other on a platen roller, so that a record-image is formed as a mirror image on an image-forming layer of the intermediate transfer film. Then, the intermediate transfer film and a target object are supplied with heat and pressure between a heating roller and a pressure roller, so that the record-image is transferred along with the image-forming layer of the intermediate transfer film to the target object. The intermediate transfer film and the ink ribbon are respectively accommodated in cassettes detachably mounted in the apparatus, and are used for forming the record-image while being fed from the cassettes.

  • Patent number: 5566379
    Abstract: An audio signal recording and reproducing apparatus can perform realtime processing with a structure having a low cost. The audio signal recording and reproducing apparatus records a series of input audio signals as digital audio data, and reproduces and outputs the input signals using the recorded digital audio data as output audio signals. An input audio signal processing unit converts the series of input audio signals into digital audio data. A data file recording unit records the digital audio data, as digital audio data file information, on a recording medium, the recording medium having a plurality of clusters in which data having a predetermined number of bytes is recorded, the digital audio file information being recorded over a plurality of clusters. A file management information recording unit records on the recording medium file management information representing the reproducing order of the clusters in which the digital audio data file information is recorded.
