PROBLEM TO BE SOLVED: To shorten a time required for the ink melt of a solid ink.SOLUTION: A volumetric container for storing phase-change ink includes a housing 204 that is comprised primarily of a thermally insulating material and a heater element 212 positioned in the housing. The heater element has a surface area larger than a surface area defined based on the height and width of a space amount. At least part of the heater element disposed to approach an outlet 224 in fluid communication with a printing apparatus melts the solid ink disposed to approach the outlet more quickly than one in the rest part of the space area, and thereby printing operation can be performed.

PROBLEM TO BE SOLVED: To provide a printhead and reservoir for use in a solid ink printing system. SOLUTION: The printhead and reservoir assembly is provided with an ink input port, an ink reservoir for holding ink to be stored through the ink input port, an ink channel to distribute ink to a jetting port and an air vent present at the top of the channels for discharging air bubbles from a jetting ink path when pressure is applied. The air vents have channels separate from the jetting fluid path that exit a jet stack. A manifold plate has at least one manifold to direct ink to a jetting path. Each manifold plate has a bottom edge and a top edge, the top edge being scalloped to form traps, and manifold plate outlets correspond to siphon and vents on the back side of the manifold plate such that air exits to the front side of the manifold plate.

PROBLEM TO BE SOLVED: To provide a system which efficiently reduces the power consumption of a device. SOLUTION: In a process for controlling a power consumption level in the device, the device is operated at a complete-operation power level; a first standby time is counted; and a first standby time changer is changed in response to the detection of the use of the device before the completion of the first standby time. Additionally, the power consumption is reduced to a low power level from the complete operation level in response to the completion of the first standby time. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To let out air trapped in a cavity in an ink reservoir of a print head. SOLUTION: This print head reservoir for use in an inkjet printer comprises a main body, an ink bucket and a filter 76. Ink cavities 74 and 86 are formed in the main body. The ink cavity comprises a cavity inlet, a cavity outlet, and a vent hole 100 which is positioned above the cavity inlet so as to let out the air from the ink cavity. The ink bucket is attached to the main body. The ink bucket communicates with the cavity through the cavity inlet. The air in the cavity is discharged from the vent hole and returned to the ink bucket. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To purge a printhead only with as small quantity of ink as possible by using a positive pressure purging system. SOLUTION: A printhead reservoir includes: a plate 12 having first and second sides; and a passage extending through the plate. The plate defines an angled channel 98 in communication with the passage. The plate also defines an outlet region 102 in communication with the channel 98. The channel 98 consists of sloping portions and defines an outlet region 102 at an apex of the sloping portions. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To perform effective recovery and movement of purged ink.SOLUTION: An inkjet printer includes: a plurality of inkjet ejectors 116; a receptacle 132 mounted adjacent to the plurality of inkjet ejectors, which has an opening 137 configured to receive ink purged from the plurality of inkjet ejectors and a discharge port 138 fluidly connected to an ink reservoir 154; and a one-way valve 140 for allowing a single conduit 160 to supply the ink to the ink reservoir 154 and for withdrawing the purged ink from the receptacle 132 into the ink reservoir 154. A bidirectional pump 158 is alternately operated in both directions to withdraw the ink from the receptacle 132 when supplying the ink into the ink reservoir 154.
Abstract:
PROBLEM TO BE SOLVED: To provide a thermal insulating blanket exhibiting excellent heat insulating performance, thin and flexible, easily manufacturable at low cost. SOLUTION: The thermal insulating blanket includes a plurality of film layers, and at least one conductive barrier arranged between at least two of the plurality of the film layers. At least one of the plurality of the film layers include a film coated on at least one side with a heat reflective material. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To prevent suction of ink into a jetting part from being disturbed due to a pressure drop by filter resistance and to suppress cost required for the filter. SOLUTION: A filter 14, which checks granular substances to prevent the jetting part being a nozzle 28 from being clogged, is provided on a path or an ink injection path 22 for leading ink from the ink pouring port 12 allowing the ink supplied from an ink source to pass through to a chamber 16 to store the ink. The chamber 16 located between the filter 14 and the nozzle 28 once stores the ink, allowing the nozzle 28 to normally suck the ink against a reduction in pressure generated between the filter 14 in front and the filter at the back. The filter 14 may be small and inexpensive to be fitted into an ink injection opening 12. A vent hole 18 at the top of the chamber 16 forms a ventilation path 26, allowing the inner pressure of the chamber 16 to be automatically adjusted. Preferably, the vent hole 18 is provided with a filter for checking foreign matters. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a system for recycling waster phase change ink in a phase change ink imaging device.SOLUTION: A system for recycling a waste phase change ink in a phase change ink imaging device includes a waste ink collector positioned within the phase change ink imaging device to collect the waste phase change ink produced by a printhead 33 in the phase change ink imaging device. The waste ink collector includes a heater for heating the waste phase change ink in the collector to at least a phase change ink melting temperature. A waste phase change ink conveyor is configured to convey the melted waste phase change ink from the waste ink collector to an ink reservoir for the printhead 33.
Abstract:
PROBLEM TO BE SOLVED: To provide an improved aperture plate used for an aperture plate for an inkjet printing head that can provide a desired emissivity and reduce radiation power loss.SOLUTION: The aperture plate 10 includes: a first layer 12 having a first emissivity; a second layer 14 having a second emissivity and disposed over the first layer, wherein the first emissivity is higher than the second emissivity; and at least one additional layer 18 disposed over the second layer including a coating layer for controlling a contact angle.
