A system and method for disassembling and assembling a product. The system includes a production facility for assembling a product, a processing facility for disassembling a used product and offering the unit or parts of the used product for assembling the product after the unit and parts are processed, and a commonly-used processing facility for practicing mutually reversible steps between the process of assembling the product and the process of disassembling the used product and offering the unit and parts for assembling the product and/or for practicing steps which are identical for the assembling and disassembling processes. The method includes the steps of performing an assembling process, performing a disassembling process, and performing in a commonly-used processing facility mutually reversible steps between the assembling and disassembling process and/or performing steps which are identical for the assembling and disassembling processes.

Product disassembling and assembling system and a method of disassembling and assembling the product

A cleaning system and a cleaning method is provided with a cleaning medium comprising a magnetic substance and a magnetic field generating device for applying a magnetic force to the magnetic substance in the cleaning medium so that the magnetic substance and the area to be cleaned are rubbed together. The area to be cleaned is cleaned by the rubbing action of the cleaning medium. The interior of the cleaned object not reachable by hands or instruments can be easily cleaned with this device. The cleaning medium, made of a magnetic substance, is guided into the interior of the cleaned object. The magnetic field generating device generates a magnetic field in the cleaning medium and thereby applies a force to the magnetic substance. By rubbing the magnetic substance on the inner wall surface of the area to be clean, the object can be cleaned efficiently.

Cleaning system and a method of cleaning

In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a transfer paper sheet, the toner on the transfer paper sheet is heated to be melted or softened. An offset belt having adhesive force stronger than that between the transfer paper sheet and the toner comes in contact with the toner. The toner is separated and removed from the transfer paper sheet when the offset belt and the transfer paper sheet are separated from each other. Heating of the toner is maintained until the transfer paper sheet is separated from the offset belt. The transfer paper sheet is separated from the offset belt before the toner is cooled and solidified. A toner heating maintaining device is constructed by using a heating-supporting member having a heater therein and arranged such that the transfer paper sheet and the offset belt are supported between the heating-supporting member and a heating roller. The heating-supporting member has a bent portion on a downstream side in a conveying direction of the transfer paper sheet.

Method and apparatus for removing image forming substance from image

An image forming substance removing apparatus for preventing an unstabilizing liquid from being excessively applied to a sheet material unnecessarily, preventing a bad state of transporting the sheet material, and not requiring a long time for drying the sheet material is provided. In the above-mentioned apparatus, an unstabilizing liquid supplying unit applies the unstabilizing liquid to the transfer material and is constructed with an applying roller for pumping up the unstabilizing liquid by an action of its rotation, a restriction roller for bringing the applying roller into contact with the transfer paper, and others. And further, in order to move the restriction roller between a position of coming into contact with the applying roller and a position of departing therefrom, a tip end sensor for sensing the tip end of the transfer paper, a spring, and a solenoid, etc. are provided in the apparatus.
