An inkjet printing apparatus includes a surface acoustic wave module including an inner passage and a surface acoustic wave generator around the inner passage; and an outflow passage connected to the surface acoustic wave module to discharge ink, where the outflow passage includes a first outflow passage connected to the inner passage to discharge first ink particles and a second outflow passage connected to the inner passage to discharge second ink particles having an average diameter smaller than that of the first ink particles, and the surface acoustic wave generator is closer to the second outflow passage than the first outflow passage.

A memory cell includes an input coupled to a read line, an output coupled to a circuit ground, a bi-polar memristor, and at least one address switch coupled to an address line to select the memory cell. A memory includes the bi-polar memristor and a one-way current conducting device, wherein the one-way current conducting device is positioned between the memristor cell output and the circuit ground, or between the read line and the memristor cell input.

In some examples, a print cartridge includes a memory device comprising quantized coefficients derived from a lossy compression, at a selected step size, of a difference color table including a plurality of difference nodes in which each difference node represents a difference value that is a difference of a value of a node of a color table and a value of a corresponding node of a reference table, the quantized coefficients useable to produce a reconstructed difference color table including a first set of difference nodes each representing a difference value that is within an error threshold at the selected step size, and a second set of difference nodes each representing a difference value that is outside an error threshold at the selected step size. The memory device further comprises corrective information to correct the second set of difference nodes of the reconstructed difference color table.

A fluidic delivery device includes a fluid supply containing a fluid, the fluid supply has a fluid reservoir and a pair of fluid permeable compressible bodies located in the fluid reservoir. One of the fluid permeable compressible bodies has an effective greater density than the other fluid permeable compressible body.

A liquid supply device includes a connection body which includes a liquid introduction portion which is capable of connecting to a liquid outlet portion of a liquid container which includes the liquid outlet portion which contains the liquid which is supplied to the liquid ejecting unit which ejects the liquid and is capable of guiding out the liquid, a liquid container support portion which is capable of supporting the liquid container in a state in which the liquid introduction portion is capable of being connected to the liquid outlet portion to be capable of being freely attached and detached, and a connection body holding portion which holds the connection body in a state in which a connection of the liquid introduction portion with the liquid outlet portion is released.

A liquid ejecting apparatus includes a liquid ejecting head ejecting liquid onto a medium transported on a transport path extending in a depth direction, a carriage holding the liquid ejecting head and reciprocally moving in a width direction so as to cross the transport path, and a waste liquid containing portion containing waste liquid discharged from the liquid ejecting head. The carriage includes a plurality of liquid containers that contain the liquid and are mounted on the carriage in such a manner that a plurality of the liquid containers are arranged side by side with each other in the depth direction. A portion of the carriage overlaps the waste liquid containing portion in a vertical direction when the liquid ejecting head is outside the transport path.

When a filter for example is provided in a liquid supply path in the manufacture of a liquid ejection head, the filter can be prevented from being displaced or deformed. A manufacture method of a liquid ejection head having a liquid ejection unit for ejecting liquid and a liquid supply unit for supplying liquid to the liquid ejection unit has a processing of abutting a filter to a melting unit provided in the liquid supply unit and applying heat to the melting unit via the filter to melt the melting unit to thereby fix the filter to the melting unit, and a processing of burying the melting unit fixed to the filter by molding material.

A shaping device, that shapes a three-dimensional object, includes an ink jet head that discharges an ink to become a material of shaping; and an ink supplying unit that supplies a pre-toned ink, which is the ink toned in advance in accordance with a color to be colored on the 3D object, to the ink jet head, where the ink jet head forms at least one part of the 3D object while coloring the one part with the color of the pre-toned ink by discharging the pre-toned ink.
