Publication number: 20120165188Abstract: The present disclosure provides a microwaveable information destruction apparatus for rendering unreadable indicia printed on a label. In various embodiments the apparatus comprises an attachable information destruction strip structured and operable to be adhered to a substrate having disposed thereon a thermally responsive label with indicia printed thereon and/or the thermally responsive label. The information destruction is attachable such that the information destruction strip is in a thermally conductive relationship with the thermally responsive label. The information destruction strip is sized to cover at least the indicia printed on the thermally responsive label. Additionally, the information destruction strip comprises a microwave activated material operable to generate heat when exposed to microwave energy.Type: ApplicationFiled: December 8, 2011Publication date: June 28, 2012Inventor: Timothy Croskey

Publication number: 20120149562Abstract: According to one embodiment, first and second branch paths of a decoloring apparatus are formed downstream in a sheet conveying direction of a reading section in a conveying path. A diverting section is provided at a branch point of the first and second branch paths in the conveying path. A control section determines on the basis of image data whether decoloring processing should be applied to a sheet, diverts, if determining that the decoloring processing should be applied to the sheet, the sheet to the first branch path with the diverting section, and diverts, if determining that the decoloring processing should not be applied to the sheet, the sheet to the second branch path with the diverting section. A decoloring section is provided between the reading section and the branch point in the conveying path and heats the sheet to decolor an image formed with a decolorable color material.Type: ApplicationFiled: December 8, 2011Publication date: June 14, 2012Applicants: Toshiba Tec Kabushiki Kaisha, Kabushiki Kaisha ToshibaInventors: Ken IGUCHI, Isao Yahata, Takahiro Kawaguchi, Hiroyuki Taguchi, Hiroyuki Tsuchihashi, Hiroyuki Taki

Patent number: 8163670Abstract: To provide a thermal recording medium, which can realize easy maintenance, does not produce wastes such as cartridges, and can realize easy control of recording sheets, and an apparatus and method for image formation. [MEANS FOR SOLVING PROBLEMS]A high-temperature color development capsule (23), a low-temperature color development capsule (27), and a low-temperature color development suppression capsule (28) are incorporated in a recording sheet (10). In a printer, the low-temperature color development capsule (27) is subjected to low-temperature color development and is then pressed to break the low-temperature color development suppression capsule (28), whereby low-temperature color development is fixed. Thereafter, the high-temperature color development capsule (23) is subjected to high-temperature color development.Type: GrantFiled: April 16, 2007Date of Patent: April 24, 2012Assignee: Alps Electric Co., LtdInventor: Hiroyasu Miyata
