  • Patent number: 8540337
    Abstract: A disclosed image forming apparatus is capable of solving the problems of deterioration of a foam application function and driving systems caused by the dried and fixed foam remaining without being applied. The image forming apparatus includes a foam forming section forming foam, a reservoir section supplying foam formed by the foam forming section to an application roller, a discharge channel through which extra foam is collected from the reservoir section, and a heating unit for heating the extra foam to return the extra foam to a liquid form. The discharged liquid prepared by defoaming the foam discharged through the discharge channel is returned to a container containing the defoamed liquid.

  • Patent number: 8474946
    Abstract: An image forming apparatus is disclosed that includes an image forming unit that forms an image on a medium to be recorded; and a foam application unit that applies a foam generated from at least any one of a liquid and a gel to the medium to be recorded or an intermediate member for applying the foam to the medium to be recorded. The foam application unit has a foam generation unit that generates the foam, an application unit that applies the generated foam to the medium to be recorded or the intermediate member, a foam supplying path through which the generated foam is supplied to the application unit, and a unit that increases a volume of the foam supplying path. The foam application unit increases the volume of the foam supplying path when stopping the supply of the foam to the application unit.

  • Patent number: 8398225
    Abstract: A foamed liquid coating apparatus prevents curling or warping of a sheet caused by coating irregularities when coated with a preprocessing solution using a coating roller or a liquid discharge head. The foamed liquid coating apparatus includes a container holding a liquid that can be foamed. A first foamed liquid producing/transporting unit produces a foamed liquid having a foam size greater than a required foam size from the liquid supplied from the container. A second foamed liquid producing/transporting unit produces a foamed liquid having the required foam size from the foamed liquid produced by the first foamed liquid producing/transporting unit. The foamed liquid produced by the second foamed liquid producing/transporting unit is applied onto a first coating roller. The foamed liquid is further supplied from the first coating roller to a second coating roller that coats a sheet with the foamed liquid.

  • Patent number: 7905573
    Abstract: A liquid ejection head includes a nozzle plate having a nozzle that ejects liquid drops, an actuator that deforms a portion of the nozzle plate surrounding the nozzle with heat, and a flow path member opposing the nozzle plate, which forms a flow path for guiding liquid to the nozzle. A fluidity resistance path is provided in the flow path between a nozzle plate portion surrounding the nozzle and a portion of the flow path member opposing the nozzle plate portion. A fluidity resistance of the fluidity resistance path is changed by deforming the nozzle plate portion.

  • Patent number: 5758040
    Abstract: An energy-saving unit causes a facsimile apparatus to enter an energy-saving mode in which power consumption is reduced in the facsimile apparatus, and further determines to cause the facsimile apparatus to exit the energy-saving mode when a predetermined cause has been detected. A main control unit controls the entirety of the facsimile apparatus and supplies an energy-saving control signal to the energy-saving unit, the energy-saving control signal indicating instructions that the energy-saving unit is to perform. The energy-saving unit supplies an energy-saving canceling cause signal to the main control unit, the energy-saving canceling cause signal indicating the predetermined cause due to which the energy-saving unit has determined to cause the facsimile apparatus to exit the energy-saving mode.
